Comparison of blood flow changes with soft tissue mobilization and massage therapy

Comparison between effects of instrument-assisted soft tissue mobilization and manual myofascial release on pain, range of motion and function in myofascial pain syndrome of upper trapezius - A randomized controlled trial

Background

Myofascial pain syndrome (MPS) is a muscle pain disorder characterized by the presence of Myofascial Trigger Point (MTrP) within a taut band, local tenderness, referral of pain to a distant site, restricted range of motion, and autonomic phenomena. The upper trapezius is the muscle most often affected by MTrPs. Manual myofascial release (MFR) and Instrument-Assisted Soft Tissue Mobilization (IASTM) are techniques of soft tissue release that are used to resolve MPS. Fifty six percent of physiotherapists complain of pain in multiple areas due to the massage and manual therapy that they have to perform.

Objective

The objective of this study is to find whether IASTM is better than manual MFR in treating patients with MPS in upper trapezius.

Methods

This study was a single-blinded randomized controlled trial that included 31 participants, both males and females between the age groups of 18-50 years. Participants were randomly divided into two groups. Three sessions were given over a period of one week for both groups. Group A received IASTM along with conventional treatment and Group B received Manual MFR along with the conventional treatment. The outcome measures evaluated were pain, cervical range of motion, pain pressure threshold (PPT) of trigger points, and the neck disability index. Pre- and post-measurements were taken and the analysis was done.

Results

Both the treatment methods significantly reduced pain, improved PPT, range of motion, and function. The effects between the groups showed that IASTM was significantly better than manual MFR to reduce pain. The improvement in PPT, range of motion and function were equal in both the groups.

Conclusion

IASTM and manual MFR both are effective individually as treatment procedures for pain, PPT, range of motion, and function. Neither of the treatment options can be considered better that the other. The clinician can decide based on the availability of the instrument, training, patient's preference, and his/her comfort whether which of the two treatment methods should be used.

Effect of instrument-assisted soft tissue mobilization combined with exercise therapy on pain and muscle endurance in patients with chronic neck pain: a randomized controlled study

OBJECTIVES

The use of instrument-assisted soft tissue mobilization (IASTM) has been documented to be effective for improving pain and function, but it is unclear whether it helps improve muscle performance in musculoskeletal diseases. This study investigated the effects of IASTM combined with exercise therapy on muscle endurance and pain intensity in patients with chronic neck pain.

METHODS

Forty-eight individuals with chronic neck pain were randomly divided into exercise therapy (ET, n = 24) and combined therapy (CT, n = 24) groups. For 4 weeks, each group underwent exercise therapy 3 days a week for a total of 12 sessions. The ET group received exercise therapy only. The CT group received IASTM combined with exercise therapy twice per week for a total of 8 sessions. The muscle endurance of the participants was assessed with the Deep Neck Flexor Muscle Endurance (DNFE) test and pain intensity with Visual Analogue Scale (VAS) at baseline and post-treatment.

RESULTS

While both groups showed significant improvement in pain intensity (p < 0.05), the CT group showed a greater effect size for pain (CT group: Cohen's d = 3.28; ET group: Cohen's d = 2.12). The CT group showed significant improvement for muscle endurance (p < 0.05), whereas the ET group did not (p > 0.05).

CONCLUSION

In the current study, the IASTM intervention combined with ET improved pain and muscular endurance in participants with chronic neck pain compared to exercise therapy alone. As an alternative method, IASTM intervention before exercise seems to increase the short-term recovery effect in chronic neck pain conditions.

Differential Effects of Classical vs. Sports Massage on Erector Spinae and Upper Trapezius Muscle Stiffness: A Shear-Wave Elastography Study in Young Women

Classical and sports massages are commonly used interventions, but their comparative effects on muscle stiffness remain unclear. Classical massage is more general and uses light to moderate pressure, and its main purpose is relaxation. Sports massage, on the other hand, is more specialized and targets the unique needs of massaged individuals using moderate to firm pressure. This study aimed to evaluate the impacts of classical and sports massages on the stiffness of the erector spinae (ES) and upper trapezius (UT) muscles. Fifteen recreationally active young women, aged 22.9 ± 1.2 years, underwent a randomized cross-over study (with three conditions). Participants received either a five-minute classical or sports massage or a passive rest as a control on distinct days. Muscle stiffness was assessed using shear-wave elastography. The ES shear modulus displayed a significant time effect (p < 0.001; η2 = 0.515) without noticeable differences between the conditions, and the time × massage-type interactions approached statistical significance (F = 2.014; p = 0.073). There was also a large and statistically significant effect of the time on the UT (F = 11.127; p < 0.001; η2 = 0.443). We could not prove that classical and sports massages reduced muscle stiffness. The absence of significant differences might be attributed to the specific intervention parameters (massage duration of 5 min) and the small, only young women sample size. Given some tendencies towards significant effects, larger sample sizes are needed to further investigate this research question.

Effectiveness of instrument assisted soft tissue mobilization versus foam rolling on trigger point release in calf muscles

BACKGROUND

Instrument assisted soft tissue mobilization and foam rolling are two techniques that have been proven effective in treating Myofascial Trigger Points, irrespective of the type of trigger point. However, little is known about the comparative effectiveness of Instrument assisted soft tissue mobilization and foam rolling. This study proposed to evaluate the effectiveness of either technique on plantar flexors trigger points, ankle dorsiflexion, and lower limb power present in the calf muscles in non-symptomatic patients.

METHOD

Forty-two subjects with bilateral calf muscle tightness, at least one trigger point in the calf muscle, and fulfilling the inclusion criteria were randomly assigned to either of the groups. Group A was treated for gastrocnemius and soleus trigger points using Instrument assisted soft tissue mobilization and Group B was treated using the Foam Rolling method. Treatment was given every alternate day, a total of 3 sessions. Subjects were evaluated on 1st and 3rd sessions for pre-post differences of ankle dorsiflexion Range of motion in weight bearing and non-weight bearing position, pressure pain threshold for gastrocnemius trigger point 1(G1), 2(G2), and soleus point 1(S1) on both sides, and lower limb power.

RESULT

Within group analyses, both groups had shown statistically significant results for all parameters except gastrocnemius trigger point 2 of foam rolling. For between group comparison foam rolling had a statistically significant result in non-weight bearing ankle dorsiflexion range of motion.

CONCLUSION

Both Instrument assisted soft tissue mobilization and Foam rolling were equally effective for treating calf trigger points. But foam rolling was more effective in improving ankle dorsiflexion range of motion.

Comparison of the effectiveness of instrument-assisted soft tissue mobilization and extracorporeal shock wave therapy in myofascial pain syndrome

Background/aim

To compare the effectiveness of instrument-assisted soft tissue mobilization (IASTM) and extracorporeal shock wave therapy (ESWT) used in myofascial pain syndrome (MPS) and to determine whether they are superior to conservative treatment (CT).

Materials and methods

A total of 42 female patients (aged 18-60 years) diagnosed with MPS were enrolled and randomly assigned to either the CT (n = 14), CT+IASTM (n = 14), or CT+ESWT group (n = 14). All of the groups received treatment for 3 weeks (CT: 5 sessions per week, 15 sessions in total, ESWT and IASTM: 2 sessions per week, 6 sessions in total). Neck stretching exercises were given to all of the patients as a home program. The pain intensity of the patients was determined using the visual analog scale (VAS). The pressure pain threshold (PPT) was measured with an algometer. Cervical joint range of motion (ROM) was measured with a cervical ROM (CROM) device. Pain, cervical disability, quality of life, and sleep disturbances were evaluated with the Neck Outcome Score (NOOS). Depression and anxiety parameters were evaluated with the Hospital Anxiety and Depression Scale (HADS). Evaluations were made before treatment and 3 days after the last treatment session.

Results

The CT+IASTM group was more successful than the other groups in terms of pain intensity, PPT, and improvements in the ROM parameters (p < 0.05). No significant difference was found between the NOOS and HADS scores of the groups when the posttreatment changes were compared to pretreatment (p > 0.05).

Conclusions

All 3 of these treatments can be used to alleviate the negative effects of MPS. IASTM treatment can be preferred primarily in the creation of combined treatment programs for patients with ROM limitations and low PPTs.

Effectiveness of instrument assisted soft tissue mobilization (IASTM) and muscle energy technique (MET) on post-operative elbow stiffness: a randomized clinical trial

BACKGROUND

Stiffness is a common complication following trauma and surgeries around the elbow, which can result in upper limb functional disabilities. Soft tissue mobilization techniques such as Instrument-assisted Soft Tissue Mobilization (IASTM) and Muscle Energy Technique (MET) have limited evidence in elbow rehabilitation. This study aimed to compare their effects on postoperative elbow stiffness.

METHODOLOGY

26 subjects were recruited (13 each group) with postoperative elbow stiffness (minimum 6 weeks post surgery) and randomly allocated in two groups: IASTM and MET. Pain [Numeric Pain Rating Scale NPRS)], ROM (Goniometer), and Function [Disability of Arm, Shoulder and Hand (DASH) and Patient-Specific Functional Scale (PSFS)] were assessed at baseline and post-intervention.

RESULTS

The data of 26 subjects were analyzed and both groups significantly improved in outcome scores post-intervention. The improvements in ROM and function between groups were comparable, but NPRS and PSFS showed greater improvement in the IASTM group (p < 0.05).

CONCLUSION

IASTM and MET were both effective in improving outcomes in postoperative elbow stiffness. IASTM was more effective in improving pain and patient-specific function.

Instrumented assisted soft tissue mobilization vs extracorporeal shock wave therapy in treatment of myofascial pain syndrome

BACKGROUND

Active myofascial trigger points (TrPs) often occur in the upper region of the upper trapezius (UT) muscle. These TrPs can be a significant source of neck, shoulder, and upper back pain and headaches. These TrPs and their related pain and disability can adversely affect an individual’s everyday routine functioning, work-related productivity, and general quality of life.

AIM

To investigate the effects of instrument assisted soft tissue mobilization (IASTM) vs extracorporeal shock wave therapy (ESWT) on the TrPs of the UT muscle.

METHODS

A randomized, single-blind, comparative clinical study was conducted at the Medical Center of the Egyptian Railway Station in Cairo. Forty patients (28 females and 12 males), aged between 20-years-old and 40-years-old, with active myofascial TrPs in the UT muscle were randomly assigned to two equal groups (A and B). Group A received IASTM, while group B received ESWT. Each group was treated twice weekly for 2 weeks. Both groups received muscle energy technique for the UT muscle. Patients were evaluated twice (pre- and post-treatment) for pain intensity using the visual analogue scale and for pain pressure threshold (PPT) using a pressure algometer.

RESULTS

Comparing the pre- and post-treatment mean values for all variables for group A, there were significant differences in pain intensity for TrP1 and TrP2 (P = 0.0001) and PPT for TrP1 (P = 0.0002) and TrP2 (P = 0.0001). Also, for group B, there were significant differences between the pre- and post-treatment pain intensity for TrP1 and TrP2 and PPT for TrP1 and TrP2 (P = 0.0001). There were no significant differences between the two groups in the post-treatment mean values of pain intensity for TrP1 (P = 0.9) and TrP2 (P = 0.76) and PPT for TrP1 (P = 0.09) and for TrP2 (P = 0.91).

CONCLUSION

IASTM and ESWT are effective methods for improving pain and PPT in patients with UT muscle TrPs. There is no significant difference between either treatment method.

Effect of massage on retinol skin penetration

Topical administration of active substances may be promoted by optimizing not only the vehicle formulation but also the application protocol. The formulation aspects are widely studied in the literature while a few works are dedicated to the development of application methods. In this context, we studied an application protocol usable as a part of skincare routine by investigating the effect of massage on the skin penetration of retinol. Retinol is a lipophilic molecule widely used as an anti-ageing firming agent in cosmetic formulations. Massage was applied to pig skin explants mounted to Franz diffusion cells after or before the deposit of the retinol-loaded formulation. Thetype of skin massage (roll or rotary type) and its duration were varied.The massage protocol had a significant influence on retinol skin penetration. Due to its highly lipophilic character, retinol accumulated into the stratum corneum but, depending on the massage protocol, a significant retinol concentration was obtained after 4 hours in epidermis and dermis layers. Results showed that the roll-type massage was significantly more efficient than the rotary process that exhibited little effect on retinol cutaneous penetration. Such results could be interesting for the development of massage devices in association with cosmetic formulations.

The Effects of Light Pressure Instrument-Assisted Soft Tissue Mobilization at Different Rates on Grip Strength and Muscle Stiffness in Healthy Individuals

CONTEXT

Instrument-assisted soft tissue mobilization (IASTM) is a popular myofascial treatment utilized by health care professionals. Currently, there is a lack of research on the effects of a light pressure IASTM treatment on the forearm region. The purpose of this study was to explore the effects of a light pressure IASTM technique at different application rates on grip strength and muscle stiffness. This study was considered exploratory with the goal of establishing methodology for future controlled studies.

DESIGN

Observational pretest and posttest clinical study.

METHODS

Twenty-six healthy adults underwent one light pressure IASTM treatment to their dominant forearm muscles. Participants were allocated to 2 groups of 13 based upon treatment rate: 60 beats per minute and 120 beats per minute. Participants were tested pretreatment and posttreatment for grip strength and tissue stiffness via diagnostic ultrasound. One-way analyses of covariance were used to assess group differences posttreatment for grip strength and tissue stiffness.

RESULTS

Statistically significant posttreatment changes for grip strength and tissue stiffness were not found. Despite the nonstatistical significance, there were small decreases in grip strength and tissue stiffness. Faster (120 beats/min) IASTM application may have produced clinically meaningful decreases in grip strength along with a small decrease in tissue stiffness.

CONCLUSIONS

This report helps to establish methodology for future controlled studies on this topic. Sports medicine professionals should consider these results as exploratory and interpret them with caution. Future research is needed to confirm these findings and begin to postulate possible neurophysiological mechanisms.

Effect of Localized Vibration Massage on Popliteal Blood Flow

There is a broad scope of literature investigating whole-body vibration (WBV) effects on blood flow (BF). However, it is unclear how therapeutic localized vibrations alter BF. Low-frequency massage guns are advertised to enhance muscle recovery, which may be through BF changes; however, studies using these devices are lacking. Thus, the purpose of this study was to determine if popliteal artery BF increases from localized vibration to the calf. Twenty-six healthy, recreationally active university students (fourteen males, twelve females, mean age 22.3 years) participated. Each subject received eight therapeutic conditions randomized on different days with ultrasound blood flow measurements. The eight conditions combined either control, 30 Hz, 38 Hz, or 47 Hz for a duration of 5 or 10 min. BF measurements of mean blood velocity, arterial diameter, volume flow, and heart rate were measured. Using a cell means mixed model, we found that both control conditions resulted in decreased BF and that both 38 Hz and 47 Hz resulted in significant increases in volume flow and mean blood velocity, which remained elevated longer than the BF induced by 30 Hz. This study demonstrates localized vibrations at 38 Hz and 47 Hz significantly increase BF without affecting the heart rate and may support muscle recovery.

Immediate Effects of Myofascial Release Treatment on Lumbar Microcirculation: A Randomized, Placebo-Controlled Trial

(1) Background: Inflammatory processes in the thoracolumbar fascia (TLF) lead to thickening, compaction, and fibrosis and are thought to contribute to the development of nonspecific low back pain (nLBP). The blood flow (BF) of fascial tissue may play a critical role in this process, as it may promote hypoxia-induced inflammation. The primary objective of the study was to examine the immediate effects of a set of myofascial release (MFR) techniques on the BF of lumbar myofascial tissue. The secondary objectives were to evaluate the influence of TLF morphology (TLFM), physical activity (PA), and body mass index (BMI) on these parameters and their correlations with each other. (2) Methods: This study was a single-blind, randomized, placebo-controlled trial. Thirty pain-free subjects (40.5 ± 14.1 years) were randomly assigned to two groups treated with MFR or a placebo intervention. Correlations between PA, BMI, and TLFM were calculated at baseline. The effects of MFR and TLFM on BF (measured with white light and laser Doppler spectroscopy) were determined. (3) Results: The MFR group had a significant increase in BF after treatment (31.6%) and at follow-up (48.7%) compared with the placebo group. BF was significantly different between disorganized and organized TLFM (p < 0.0001). There were strong correlations between PA (r = -0.648), PA (d = 0.681), BMI (r = -0.798), and TLFM. (4) Conclusions: Impaired blood flow could lead to hypoxia-induced inflammation, possibly resulting in pain and impaired proprioceptive function, thereby likely contributing to the development of nLBP. Fascial restrictions of blood vessels and free nerve endings, which are likely associated with TLFM, could be positively affected by the intervention in this study.

Instrument-Assisted Soft Tissue Mobilization Increased Hamstring Mobility

CONTEXT

Limited research reveals that the use of different soft tissue mobilization techniques increases tissue mobility in different regions of the body.

OBJECTIVE

The purpose of this study was to determine whether there is a difference between administering instrument-assisted soft tissue mobilization (IASTM) and therapeutic cupping (TC) on hamstring tightness.

DESIGN

Subjects attended one session wherein treatment and leg order were randomized before attending the session. A statistical analysis was completed using a 2 (intervention) × 2 (time) repeated-measures analysis of variance at α level ≤ .05.

PARTICIPANTS

Thirty-three subjects between the age of 18-35 years old with bilateral hamstring tightness participated in this study.

INTERVENTIONS

The IASTM and TC were administered on different legs for 5 minutes and over the entire area of the hamstring muscles. One TC was moved over the entire treatment area in a similar fashion as the IASTM.

MAIN OUTCOME MEASURES

The intervention measurements included soreness numeric rating scale, Sit-n-Reach (single leg for side being tested), goniometric measurement for straight-leg hip-flexion motion, and superficial skin temperature. The timeline for data collection included: (1) intervention measurements for the first randomized leg, (2) 5-minute treatment with the first intervention treatment, (3) intervention measurements repeated for postintervention outcomes, and (4) repeat the same steps for 1 to 3 with the contralateral leg and the other intervention.

RESULTS

There was a main effect over time for Sit-n-Reach, measurement (pre-IASTM-29.50 [8.54], post-IASTM-32.11 [8.31] and pre-TC-29.67 [8.21], post-TC-32.05 [8.25]) and goniometric measurement (pre-IASTM-83.45 [13.86], post-IASTM-92.73 [13.20] and pre-TC-83.76 [11.97], post-TC-93.67 [12.15]; P < .05).

CONCLUSION

Both IASTM and TC impacted hamstring mobility during a single treatment using only an instrument-assisted soft tissue mobilization technique without any additional therapeutic intervention.

Exploring Force Production Reliability across Different Levels of Clinical Experience during a Simulated One-handed Instrument-Assisted Soft Tissue Mobilization Treatment: A Pilot Study

Background

Instrument-assisted soft tissue mobilization (IASTM) is a commonly utilized intervention for musculoskeletal pain and dysfunction. However, little is known regarding the reliability of forces applied by clinicians of different experience levels during an IASTM intervention.

Purpose

The purpose of this pilot study was to assess intra-clinician reliability of IASTM force (i.e., mean normal force) during a simulated, one-handed stroke IASTM intervention across different levels of IASTM clinical experience.

Design

Descriptive laboratory study.

Methods

The researchers conducted a repeated measures trial in a laboratory setting with a convenience sample of ten participants who had previously completed professional IASTM training. Participants performed 15 one-handed sweeping strokes with an IASTM instrument on a skin simulant attached to a force plate for a standardized hypothetical treatment scenario. The participants performed the treatment on two separate days, 24-48 hours apart. The researchers examined the intra-rater reliability for average (mean) normal forces using Bland-Altman (BA) plots and Coefficient of Variation (CV) values.

Results

The BA plot results indicated all participants (professional athletic training students = 4, athletic trainers = 6; males = 5, females = 5; age = 32.60 ± 8.71 y; IASTM experience = 3.78 ± 4.10 y), except participant D (1.9N, 190g), were consistently reliable within 1N (100g) or less of force for mean differences and within the maximum limits of agreement around 3.7N (370g). Most participants' CV scores ranged between 8 to 20% supporting reliable force application within each treatment session.

Conclusion

The data indicated that IASTM trained clinicians could produce consistent forces within and across treatment sessions irrespective of clinical experience.

Computational modeling of posteroanterior lumbar traction by an automated massage bed: predicting intervertebral disc stresses and deformation

Spinal traction is a physical intervention that provides constant or intermittent stretching axial force to the lumbar vertebrae to gradually distract spinal tissues into better alignment, reduce intervertebral disc (IVD) pressure, and manage lower back pain (LBP). However, such axial traction may change the normal lordotic curvature, and result in unwanted side effects and/or inefficient reduction of the IVD pressure. An alternative to axial traction has been recently tested, consisting of posteroanterior (PA) traction in supine posture, which was recently shown effective to increase the intervertebral space and lordotic angle using MRI. PA traction aims to maintain the lumbar lordosis curvature throughout the spinal traction therapy while reducing the intradiscal pressure. In this study, we developed finite element simulations of mechanical therapy produced by a commercial thermo-mechanical massage bed capable of spinal PA traction. The stress relief produced on the lumbar discs by the posteroanterior traction system was investigated on human subject models with different BMI (normal, overweight, moderate obese and extreme obese BMI cases). We predict typical traction levels lead to significant distraction stresses in the lumbar discs, thus producing a stress relief by reducing the compression stresses normally experienced by these tissues. Also, the stress relief experienced by the lumbar discs was effective in all BMI models, and it was found maximal in the normal BMI model. These results are consistent with prior observations of therapeutic benefits derived from spinal AP traction.

The effects of instrument-assisted soft tissue mobilisation and kinesiology taping on pain, functional disability and depression in patients with chronic low back pain: A randomised trial

Objectives: Low back pain is a common condition that can become chronic, which reduces the life quality of the patient by causing functional disability and depression. This study aimed to investigate the effects of instrument-assisted soft tissue mobilisation (IASTM) and kinesiology taping (KT) along with conservative treatment in patients with chronic nonspecific low back pain. Patients and methods: A total of 30 patients (22 males, 8 females; mean age IASTM = 37.3 ± 7.1 years, KT = 37.3 ± 6.6 years; range, 30–50 years) with chronic nonspecific low back pain (CNLBP) were randomised into the IASTM (n = 15) and KT (n = 15) groups. Both the groups underwent conservative treatment that comprised of a hot pack, ultrasound, transcutaneous electrical nerve stimulation and home exercises. The pain level was assessed using the Visual Analog Scale, the functional impairment level was assessed using the Roland Morris Disability Questionnaire and the level of depression was measured using the Beck Depression Inventory. The measurements were carried out at the beginning and end of the treatment. Results: The two methods did not have superiority over each other in parameters like pain, functionality and depression (p>0.05). Conclusion: IASTM and KT have therapeutic effects on pain, functionality and depression in patients with CNLBP.

The Effectiveness of Massage Therapy on Healing of Diabetic Neuropathy in Diabetes Mellitus Patients

BACKGROUND: Diabetic neuropathy reduces the patient’s quality of life and the quality of diabetes management itself and, as a result, worsens the prognosis of other diabetic complications. Various complaints that are often felt by diabetes mellitus (DM) patients due to neuropathy include pain in the legs, numbness, and weakness in the affected leg, paresthesia, or numbness, and the absence of tendon reflexes in the affected leg. AIM: This study aimed to determine the effectiveness of electric massage therapy on neuropathy healing in DM patients. METHODS: The pre-test and post-test experimental design without a control group was employed. Patients with neuropathy diabetic were recruited as the subject of the study. The total number of participants in the study was 30 people. All the subjects were assessed for neuropathy using the neuropathy assessment instrument and the monofilament test. The Kolmogorov–Smirnov test was employed to analyze the normality of the data. The Wilcoxon signed-rank test was employed for non-normally distributed data. The study used a 95% confidence interval, and significance was assessed at alpha <0.05. RESULTS: Mean difference test resulted that the Z value was −4.791; (p < 0.01). These results indicate that there was a statistically significant difference in the level of neuropathy before and after the massage therapy intervention. CONCLUSIONS: Foot massage therapy has a significant effect in reducing the complaints of diabetic peripheral neuropathy (DPN). It is recommended for the DPN patients to conduct foot massage independently regularly as an alternative treatment in-home care treatment.

Evaluation of Local Skeletal Muscle Blood Flow in Manipulative Therapy by Diffuse Correlation Spectroscopy

Manipulative therapy (MT) is applied to motor organs through a therapist’s hands. Although MT has been utilized in various medical treatments based on its potential role for increasing the blood flow to the local muscle, a quantitative validation of local muscle blood flow in MT remains challenging due to the lack of appropriate bedside evaluation techniques. Therefore, we investigated changes in the local blood flow to the muscle undergoing MT by employing diffuse correlation spectroscopy, a portable and emerging optical measurement technology that non-invasively measures blood flow in deep tissues. This study investigated the changes in blood flow, heart rate, blood pressure, and autonomic nervous activity in the trapezius muscle through MT application in 30 volunteers without neck and shoulder injury. Five minutes of MT significantly increased the median local blood flow relative to that of the pre-MT period (p &lt; 0.05). The post-MT local blood flow increase was significantly higher in the MT condition than in the control condition, where participants remained still without receiving MT for the same time (p &lt; 0.05). However, MT did not affect the heart rate, blood pressure, or cardiac autonomic nervous activity. The post-MT increase in muscle blood flow was significantly higher in the participants with muscle stiffness in the neck and shoulder regions than in those without (p &lt; 0.05). These results suggest that MT could increase the local blood flow to the target skeletal muscle, with minimal effects on systemic circulatory function.

Positional release therapy and therapeutic massage reduce muscle trigger and tender points

OBJECTIVE

To determine if positional release therapy (PRT) or therapeutic massage (TM) was more effective in the treatment of trigger and tender points in the upper trapezius muscle.

BACKGROUND

Trigger points in the upper trapezius muscle are common and can be painful. Trigger points are commonly treated using TM however, PRT is a novel treatment that deserves further investigation.

METHODS

Sixty healthy male (24) and female (36) participants, (age = 27.1 ± 8.8 years, wt = 75.2 ± 17.9 kg, ht = 172.8 ± 9.7 cm) presenting with upper trapezius pain and a trigger point were recruited and randomized into either the TM or PRT group. Upper trapezius trigger points were found via palpation. Pain level was evaluated using a visual analog scale (VAS) and pain pressure threshold (PPT) was assessed using a pressure algometer. Muscle thickness was measured by B-mode ultrasound, while muscle stiffness was measured by shear-wave elastography (SWE). Participants were measured at baseline, posttreatment and again 48 h later.

RESULTS

Both treatments were effective in treatment of pain and muscle stiffness. Although no statistical group differences existed, treatment using PRT showed decreased pain averages and decreased pressure sensitivity at both post treatment, and 48 h later. Neither treatment was able to maintain the reduced muscle stiffness at the 48-h measure in males.

CONCLUSION

Both treatments showed a significant ability to reduce pain and acutely decrease muscle stiffness. Although not statistically different, clinically PRT is more effective at decreasing pain, and decreasing pressure sensitivity. Neither treatment method produced a long lasting effect on muscle stiffness in males.

Effects of self-myofascial release interventions with or without sliding pressures on skin temperature, range of motion and perceived well-being: a randomized control pilot trial

Background

Self-myofascial release is an emerging technique in strength and conditioning. Yet, there is no consensus regarding optimal practice guidelines. Here, we investigated the acute effects of various foam rolling interventions targeting quadriceps muscles, with or without sliding pressures.

Methods

We conducted a blinded randomized control pilot trial in 42 healthy weightlifting athletes over 4 weeks. Participants were randomly allocated to one of the four intervention (120 s massage routine) groups: foam rolling, roller massager, foam rolling with axial sliding pressures, foam rolling with transverse sliding pressures. Knee range of motion, skin temperature and subjective scores of the perceived heat, range of motion, muscle pain and relaxation were the dependent variables. Measurements were carried on before, after and up to 15 min (follow-up) after the massage intervention.

Results

The range of motion increased immediately after the various foam rolling interventions (+ 10.72%, 95% CI 9.51 to 11.95, p < 0.001), but progressively returned back to the pre-intervention baseline along within the 15 min post-intervention. Foam rolling was the most effective intervention to increase skin temperature from thermographic measures (+ 14.06%, 95% CI 10.97 to 17.10, p < 0.001), while the increase in perceived heat was comparable in all experimental groups (107%, 95% CI 91.08 to 122.61, p < 0.001).

Conclusions

Subjective indexes of heat, range of motion, muscle pain and relaxation improved immediately after the intervention, but also gradually returned to the pre-intervention baseline. Overall, combining foam rolling with sliding pressures did not yield additional benefits from objective measures.

Comparison of the Immediate Effect of Petrissage Massage and Manual Lymph Drainage Following Exercise on Biomechanical and Viscoelastic Properties of the Rectus Femoris Muscle in Women

CONTEXT

Fast and adequate recovery after exercise and activity is important for increasing performance and preventing injuries. Inadequate recovery usually causes changes in the biomechanical and viscoelastic properties of the muscle.

OBJECTIVE

To compare the immediate effect of petrissage massage (PM) and manual lymph drainage (MLD) following submaximal exercise on the biomechanical and viscoelastic properties of the rectus femoris muscle in healthy women.

DESIGN

Cross-sectional, repeated-measures.

SETTING

Marmara University.

PARTICIPANTS

18 healthy female students.

INTERVENTION(S)

Following the submaximal quadriceps strengthening exercise performed in 3 sets of 8 repetitions with intensity of 75% of 1 maximum repetition, participants' right leg received a 5-minute PM (PM group) and the contralateral leg received a 5-minute MLD application (MLD group).

MAIN OUTCOME MEASURES

Skin temperature was measured using P45 thermographic thermal camera (Flir System; ThermaCAM, Danderyd, Sweden), and muscle tone, biomechanical, and viscoelastic features were measured with a myometer (Myoton AS, Tallinn, Estonia) at baseline, immediately postexercise, post-PM/MLD application, and 10 minutes postexercise.

RESULTS

In the PM group, the tonus (P = .002) and stiffness (P < .001) values measured after the massage and at the end of the 10-minute resting period were found to be statistically different than those measured right after the exercise (P < .05). Relaxation time and creep values at all measurement times were significantly different (P < .05). In the MLD group, it was observed the tonus (P < .001), stiffness (P = .025), and relaxation time (P < .01) values decreased significantly after the MLD compared with the values measured after the exercise; however, the creep value was found to be significantly different in all measurements (P < .05).

CONCLUSION

PM and MLD reduce passive tissue stiffness and improve the extent of muscle extensibility over time against the muscle tensile strength. PM and MLD are therapeutic methods that can be used to support tissue recovery after exercise and prevent injuries.

Combining targeted instrument-assisted soft tissue mobilization applications and neuromuscular exercises can correct forward head posture and improve the functionality of patients with mechanical neck pain: a randomized control study

Background

The purpose of this study was to evaluate the short- and intermediate-term effects of the combined application of instrument-assisted soft tissue mobilization (IASTM) techniques and neuromuscular exercises of the cervical and thoracic area on the improvement of the functionality of patients with mechanical neck pain and accompanying forward head posture (FHP).

Methods

Twenty patients with neck pain and FHP were randomized and received eight treatment sessions of either targeted IASTM in combination with neuromuscular exercises (Group A) or a classical massage and the same set of exercises (Group B). The cervical vertebral angle (CVA), cervical range of motion (ROM) and strength, pain (visual analogue scale-VAS), and neck disability index (NDI) were measured throughout the treatment period and in the two- and four-week post-treatment periods.

Results

The combined application of IASTM and neuromuscular exercises contributed to a significantly greater improvement in CVA (Group A: + 7,2 deg vs Group B: + 1,1 deg) and NDI (Group A:-25,2 vs Group B:-5,8) than massage and the application of the same exercises. Both interventions improved cervical ROM and strength in the short term. Pain was also significantly improved in both groups in both the short (Group A VAS: − 5,97 vs Group B VAS: − 3,1) and intermediate term (Group A VAS:-5,5 vs Group B:-1,5).

Conclusions

Combining IASTM and exercises for the cervical and thoracic area can induce positive postural adaptations and improve the functional status of neck pain patients.

Intermittent pressure imitating rolling manipulation ameliorates injury in skeletal muscle cells through oxidative stress and lipid metabolism signalling pathways

BACKGROUND

Traditional Chinese medicine manipulation (TCMM) is often used to treat human skeletal muscle injury, but its mechanism remains unclear due to difficulty standardizing and quantifying manipulation parameters.

METHODS

Here, dexamethasone sodium phosphate (DSP) was utilized to induce human skeletal muscle cell (HSkMC) impairments. Cells in a three-dimensional environment were divided into the control normal group (CNG), control injured group (CIG) and rolling manipulation group (RMG). The RMG was exposed to intermittent pressure imitating rolling manipulation (IPIRM) of TCMM via the FX‑5000™ compression system. Skeletal muscle damage was assessed via the cell proliferation rate, superoxide dismutase (SOD) activity, malondialdehyde (MDA) content and creatine kinase (CK) activity. Isobaric tagging for relative and absolute protein quantification (iTRAQ) and bioinformatic analysis were used to evaluate differentially expressed proteins (DEPs).

RESULTS

Higher-pressure IPIRM ameliorated the skeletal muscle cell injury induced by 1.2 mM DSP. Thirteen common DEPs after IPIRM were selected. Key biological processes, molecular functions, cellular components, and pathways were identified as mechanisms underlying the protective effect of TCMM against skeletal muscle damage. Some processes (response to oxidative stress, response to wounding, response to stress and lipid metabolism signalling pathways) were related to skeletal muscle cell injury. Western blotting for 4 DEPs confirmed the reliability of iTRAQ.

CONCLUSIONS

Higher-pressure IPIRM downregulated the CD36, Hsp27 and FABP4 proteins in oxidative stress and lipid metabolism pathways, alleviating excessive oxidative stress and lipid metabolism disorder in injured HSkMCs. The techniques used in this study might provide novel insights into the mechanism of TCMM.

The Recovery Benefit on Skin Blood Flow Using Vibrating Foam Rollers for Postexercise Muscle Fatigue in Runners

PURPOSE

To determine the effect of vibrating rollers on skin blood flow after running for recovery from muscle fatigue.

METHOD

23 healthy runners, aged between 20 to 45 years, participated in a crossover trial. Muscle fatigue was induced by running, and recovery using a vibrating roller was determined before and after the intervention. Each subject was measured at three time points (prerun, postrun, and postroller) to compare skin blood flow perfusion and blood flow oscillation at the midpoint of the dominant gastrocnemius muscle. The results show that blood perfusion is greater when a vibrating roller is used than a foam roller, but there is no statistical difference. The analysis of blood flow oscillation shows that vibrating rollers induce 30% greater endothelial activation than a foam roller. Vibrating rollers significantly stimulate the characteristic frequency for myogenic activation (p < 0.05); however, the effect size is conservative.

The Rolf Method of Structural Integration on Fascial Tissue Stiffness, Elasticity, and Superficial Blood Perfusion in Healthy Individuals: The Prospective, Interventional Study

Introduction: There are multiple theories surrounding the physiological impact of structural integration (SI) with little evidence or research corroborating any of these. The aim of the study was to assess the effectiveness of 10 sessions of SI on fascial tissue (FT) superficial blood perfusion, stiffness, and elasticity in 13 healthy women.

Methods: This was a prospective, interventional study. The primary outcome measures were FTs’ superficial blood perfusion, stiffness, and elasticity of bilateral selected FT points on the body. Data were collected before and after 10 sessions of SI intervention. Statistical analysis was performed using the non-parametric Wilcoxon test (intragroup comparison).

Results: The superficial blood perfusion increased significantly in the most selected FT points on the body (p < 0.05). SI interventions produced significant decreases in selected points (brachioradialis, biceps brachii, and trapezius; p < 0.05) of FT stiffness and significant increases in elasticity (brachioradialis, biceps brachii, triceps surae, and trapezius; p < 0.05), especially in the FT of the right (dominant) upper limb.

Conclusion: A 10-session of SI demonstrated positive effects on increasing superficial blood perfusion contributed to a decrease in FT stiffness and an increase in elasticity properties in the dominant upper limb. Data collection for this study is currently underway, and the trial is registered at ISRCTN.com with the identifier: ISRCTN46707309.

Effects of instrument-assisted soft-tissue mobilization at three different application angles on hamstring surface thermal responses

[Purpose] This study aimed to examine the thermal skin responses (thermal buildup and retention rate) to instrument-assisted soft tissue mobilization (IASTM) procedures applied on hamstrings at different angles. [Participants and Methods] Thirty university students (age: 20 ± 4 years, weight: 70.61 ± 9.11 kg, height: 168.5 ± 7.5 cm) received three sessions of 10-min Ergon^® IASTM treatment on their dominant limbs' hamstrings at 20°, 60°, and 90° application angles, respectively. The skin temperature was measured with a thermometer immediately before and after treatment, and every minute thereafter until it returned to the baseline value. [Results] IASTM resulted in a significant increase in skin temperature irrespective of the application angle. The thermal retention rate produced by the treatment at a 90° angle was significantly higher than that produced by the 20° application angle (78.9 vs. 64.53 min). No significant differences were observed between the 60° and 90° angle applications (72.5 vs. 78.9 min). [Conclusion] IASTM application at 60° and 90° angles can increase and retain the hamstring's skin temperature for more than an hour, creating the conditions for potential positive adaptations to local metabolism and muscle tone.

Knowledge and Perception of Athletes on Sport Massage Therapy (SMT)

BACKGROUND

Interest in sport massage is steadily increasing in recent times especially in developing countries. One study showed that general practitioners had minimal or no knowledge about sport massage therapy (SMT). Coaches, athletes, and sports medicine personnel have various beliefs about the benefits and efficacy of SMT. It would be prudent, therefore, for athletes who are frequent users of SMT to possess adequate knowledge and appropriate attitudes about SMT.

PURPOSE

The purpose of this study was to determine the knowledge and perceptions of athletes about SMT.

SETTING

The study setting was located in the City of Cape Town, Western Cape Province, South Africa.

RESEARCH DESIGN

A quantitative, cross-sectional and descriptive study design was used.

PARTICIPANTS

The study sample consisted of 100 conveniently sampled athletes, males and females aged 18 years and older, from various mountain biking and trail running events in the City of Cape Town.

METHODS

A researcher-generated and self-administered demographic questionnaire was distributed amongst the participants either as a hardcopy or completed online via Google forms. The knowledge and perception questionnaire consisted of 10 knowledge and 17 perception questions, and was based on previously validated questionnaires. The data were analyzed descriptively using frequencies (percentages).

RESULTS

The results of the study indicated that the participants had a moderate-to-high knowledge of SMT and that they had positive perceptions overall about SMT.

CONCLUSION

This study indicated that athletes who made use of SMT were quite knowledgeable about SMT and that they were well-disposed towards SMT as a beneficial modality for sport performance and postexercise recovery.

Comparison of Myofascial Release Techniques on Pectoralis Minor Length, Glenohumeral Total Arc of Motion, and Skin Temperature: A Pilot Study

CONTEXT

The pectoralis minor (PM) is an important postural muscle that may benefit from myofascial techniques, such as Graston Technique® (GT) and self-myofascial release (SMR).

OBJECTIVE

To examine the effects of GT and SMR on PM length, glenohumeral total arc of motion (TAM), and skin temperature.

DESIGN

Cohort.

SETTING

Laboratory.

PARTICIPANTS

Twenty-six healthy participants (19 females and 7 males; age = 20.9 [2.24] y, height = 170.52 [8.66] cm, and weight = 72.45 [12.32] kg) with PM length restriction participated.

INTERVENTIONS

Participants were randomized to the intervention groups (GT = 12 and SMR = 14). GT and SMR interventions were both applied for a total of 5 minutes during each of the 3 treatment sessions.

MAIN OUTCOME MEASURES

PM length, TAM, and skin temperature were collected before and after each intervention session (Pre1, Post1, Pre2, Post2, Pre3, and Post3) and at 1-week follow-up (follow-up). Separate intervention by time analyses of variance examined differences for each outcomes measure. Bonferroni post hoc analyses were completed when indicated. Significance was set a priori at P ≤ .05.

RESULTS

No significant intervention by time interactions were identified for PM length, TAM, or temperature (P > .05). No significant intervention main effects were identified for PM length (P > .05), TAM (P > .05), or temperature (P > .05) between the GT or SMR technique groups. Overall, time main effects were found for PM length (P = .02) and temperature (P < .001). Post hoc analysis showed a significant increase in PM length for both intervention groups at follow-up (P = .03) compared with Post2. Furthermore, there were significant increases in temperature at Post1 (P < .001), Post2 (P = .01), and Post3 (P < .001) compared with Pre1; Post2 was increased compared with Pre2 (P = .003), Pre3 (P < .001), and follow-up (P = .01); Post3 increased compared with Pre3 (P = .01) and follow-up (P = .01).

CONCLUSION

Serial application of GT and SMR to the PM did not result in increases in PM length or TAM. Regardless of intervention, skin temperature increased following each intervention.

Sedentary behaviour at work increases muscle stiffness of the back: Why roller massage has potential as an active break intervention

There is increasing evidence that subjects who are exposed to long sitting periods suffer from musculoskeletal discomfort and back pain. The underlying mechanism and effective prevention strategies are still largely unknown. In this study, muscle stiffness of the back was measured in 59 office workers who followed their usual desk work regime for 4.5 h in a sitting posture. The sitting period was either followed by an 8-min roller massage intervention or a controlled standing task. Results showed that muscle stiffness increased significantly after the 4.5 h sitting period. When the sitting period was followed by roller massage, the stiffness values dropped slightly below baseline stiffness. In contrast, the stiffness values remained increased when the sitting period was followed by controlled standing. This study indicates that short-duration tissue manipulation can be an effective active break between prolonged sitting periods to prevent musculoskeletal issues, such as musculoskeletal discomfort and back pain.

Crossover Effects of Unilateral Static Stretching and Foam Rolling on Contralateral Hamstring Flexibility and Strength

CONTEXT

Static stretching (SS) and self-administered foam rolling (SAFR) are both effective techniques often used in rehabilitation settings to improve one's range of motion (ROM). However, their effects on nonintervened contralateral limb's performance remain equivocal.

OBJECTIVE

To examine the acute effects of unilateral hamstring's SS and SAFR on the contralateral hip-flexion passive ROM and the strength performance.

DESIGN

Randomized crossover trial.

SETTING

Controlled laboratory.

PARTICIPANTS

A total of 23 healthy young adults (13 males and 10 females) participated in this investigation.

INTERVENTIONS

Ten sets of 30-second SS or SAFR were performed on the participants' dominant hamstring muscles.

MAIN OUTCOME MEASURES

Before (pre) and after (post) the interventions, the contralateral hip-flexion passive ROM, the isometric strength of the contralateral hamstrings, and surface electromyography amplitude were measured. Separate 2-way (time × intervention) repeated measures analyses of variance were used to examine the changes in the dependent variables.

RESULTS

Both interventions significantly increased the contralateral hip-flexion passive ROM. In addition, the post-ROM value was significantly greater (P = .03) for the SS (mean ± SE = 73.5° ± 4.7°) than that for the SAFR (mean ± SE = 70.3° ± 4.5°). There were also main effects for time (P = .03) and intervention (P = .02) for the contralateral hamstring strength. However, no significant interaction or main effects were found for the normalized electromyography amplitude of the knee flexor muscles.

CONCLUSIONS

The increased contralateral hip-flexion passive ROM following both interventions was likely due to the enhanced stretch tolerance. However, the differential strength performance responses might be due to different neural mechanisms, which are proposed and discussed.

Tissue Structure and Edema Fluid Events During Treatment of Lymphedema of Limbs with a Manual Pressure-Calibrated Device, Linforoll

Background: Linforoll is a device composed of handpiece with roller and pressure sensor connected wireless to the computer displaying the pressure curve of the applied force. In a previous study, we proved it to regulate the applied force according to the hydromechanic conditions of the massaged tissues. Standardization of massage based on applied force was repeatable in the same patient; it decreased limb volume and provided evident increase in tissue elasticity. Methods and Results: In this study, we measured additional parameters useful for the understanding of tissue and fluid events and approval of the device for general practice. These were skin stiffness, subcutaneous tissue stiffness independent of skin, skin water concentration, changes in skin temperature, skin capillary blood flow, subcutaneous tissue fluid pressure, volume of the moved edema fluid, and visualization of movement on indocyanine green (ICG) lymphography. Measurements were done before and during the massage. The data were obtained from a group of 20 patients with obstructive lymphedema of lower limbs during the Linforoll massage. There was a lack of significant changes in skin stiffness, skin water concentration, skin surface temperature, and capillary blood flow, but evident increase in the subcutaneous tissue elasticity (tonometry) and lymphography-shown flow of the edema fluid. Conclusions: The skin tissue hydromechanic parameters remained normal proving lack of destructive changes under high massaging pressures. The obtained data evidently show that not the skin but the subcutis accumulated edema fluid that can successfully be moved proximally under pressures of 80-120 mmHg.

Comparison of Muscle Temperature Increases Produced by Moist Hot Pack and ThermoStim Probe

Background: ThermoStim Probe (TSP) has recently joined the market as a superficial heating modality. Although there is limited research into the intramuscular heating capability of superficial heating modalities in general (moist hot pack [MHP], paraffin, warm whirlpool), no previous research has examined intramuscular heating capability of TSP. Objective: Evaluate rate and magnitude of intramuscular heating via TSP compared with hydrocollator MHP, and determine if TSP can increase tissue temperature 3°C-4°C (vigorous heating range). Design: Repeated-measures counterbalanced study. Setting: Multisite trial; 2 college/university research laboratories. Patients or Other Participants: A total of 18 healthy college-aged participants (11 females and 7 males, age: 23.0 [2.1] y, weight: 74.64 [18.64] kg, height: 168.42 [9.66] cm, subcutaneous adipose: 0.71 [0.17] cm) with calf subcutaneous adipose <1.2 cm. Interventions: MHP and TSP were applied to the posterior aspect of the nondominant calf for 20 minutes; participants underwent each treatment in a counterbalanced order. Main Outcome Measurements: Muscle temperature at a depth of 1.5 cm was measured via 21-gauge catheter thermocouple. Temperatures were recorded at baseline and during the 20-minute treatment. Results: There was a significant treatment-by-time interaction during the treatment period (F_5,85 = 14.149, P < .001), as well as significant main effects for treatment (F_1,17 = 7.264, P = .02) and for time (F_5,85 = 34.028, P < .001). Muscle temperature increased an average of 1.7° (0.9°) for the MHP and 0.6° (1.0°) for the TSP. Pairwise comparisons of the interaction (using least significant difference adjustment for multiple comparisons) indicated that MHP heated faster than TSP at minutes 12 (P = .02), 16 (P = .002), and 20 (P = .001). There was no significant correlation between subcutaneous adipose thickness and maximum temperature increase obtained with either MHP (r = -.033, P = .90) or TSP (r = -.080, P = .75). Conclusions: MHP increased intramuscular temperature significantly more than TSP; however, neither modality was capable of producing a 3°C-4°C temperature increase associated with increased tissue extensibility.

Effects of Massage as a Combination Therapy with Lumbopelvic Stability Exercises as Compared to Standard Massage Therapy in Low Back Pain: a Randomized Cross-Over Study

BACKGROUND

Little is known about the effects of providing massage as a combination therapy (CT) with lumbopelvic stability training (LPST) in management of chronic nonspecific low back pain (CLBP) among elite female weight lifters. It is unclear whether massage therapy (MT) together with LPST has any additional clinical benefits for individuals with CLBP.

PURPOSE

The current study compares the therapeutic effects of CT against MT as a stand-alone intervention on pain intensity (PI), pain pressure threshold (PPT), tissue blood flow (TBF), and lumbopelvic stability (LPS) among elite weight lifters with CLBP.

SETTING

The study was conducted at the campus for National Olympic weight lifting training camp.

PARTICIPANTS

A total of 16 professional female elite weight lifting athletes who were training for Olympic weight lifting competition participated in the study.

RESEARCH DESIGN

A within-subject, repeated measures, crossover, single-blinded, randomized allocation study.

INTERVENTION

The athletes were randomized into three sessions of CT and MT with a time interval of 24 hrs within sessions and a wash out period of four weeks between the sessions.

MAIN OUTCOME MEASURES

The PI, PPT, TBF, and LPS were measured before and after each session repeatedly in both groups of intervention. The changes in the PI, PPT, TBF, and LPS were analyzed using repeated measures analysis of variance (ANOVA).

RESULTS

The results showed that the CT significantly demonstrated greater effects in reducing pain perception (45%-51%), improving pain pressure threshold (15% up to 25%), and increasing tissue blood flow (131%-152%) than MT (p < .001).

CONCLUSION

The combination therapy of massage therapy and LPST is likely to provide more clinical benefits in terms of PI, PPT, and TBF when compared to massage as a stand-alone therapy among individuals with chronic nonspecific low back pain.

Lipedema: friend and foe

Background Lipedema is a chronic disorder presenting in women during puberty or other times of hormonal change such as childbirth or menopause, characterized by symmetric enlargement of nodular, painful subcutaneous adipose tissue (fat) in the limbs, sparing the hands, feet and trunk. Healthcare providers underdiagnose or misdiagnose lipedema as obesity or lymphedema. Materials and methods The benefits (friend) and negative aspects (foe) of lipedema were collected from published literature, discussions with women with lipedema, and institutional review board approved evaluation of medical charts of 46 women with lipedema. Results Lipedema is a foe because lifestyle change does not reduce lipedema fat, the fat is painful, can become obese, causes gait and joint abnormalities, fatigue, lymphedema and psychosocial distress. Hypermobility associated with lipedema can exacerbate joint disease and aortic disease. In contrast, lipedema fat can be a friend as it is associated with relative reductions in obesity-related metabolic dysfunction. In new data collected, lipedema was associated with a low risk of diabetes (2%), dyslipidemia (11.7%) and hypertension (13%) despite an obese average body mass index (BMI) of 35.3 ± 1.7 kg/m2. Conclusion Lipedema is a painful psychologically distressing fat disorder, more foe than friend especially due to associated obesity and lymphedema. More controlled studies are needed to study the mechanisms and treatments for lipedema.

Effect of myofascial trigger point therapy with an inflatable ball in elderlies with chronic non-specific low back pain

BACKGROUND

Myofascial trigger points (MTrPs) are related to low back pain and back muscle stiffening, and secondarily to movement impairment. MTrP therapy with an inflatable ball would improve clinical outcomes for chronic non-specific low back pain (CNSLBP) after 6 weeks.

OBJECTIVE

The aim of this study was to investigate the effects of MTrPs with an inflatable ball for the elderly with CNSLBP.

METHODS

Fifteen elderly patients with chronic non-specific low back pain were evaluated for pain, pressure sensitivity, and physical function at baseline and 1, 3, and 6 weeks of therapy. The visual analog scale (VAS) and pressure pain threshold (PPT) were used to measure pain intensity and sensitivity, respectively. Straight-leg-raise (SLR) test, back range of motion (BROM), and Oswestry disability index were used to assess physical function.

RESULTS

Significant differences were observed between the 3- and 6-week VAS scores (-34.6%; p= 0.03); baseline and 1-week (7%; p= 0.02), 1- and 3-week (-14%; p= 0.01), and 3- and 6-week PPTs (18%; p= 0.01); 3- and 6-week BROMs (Flexion, 7.1%; Extension, 41%; p= 0.048); baseline and 1-week (-6.9%; p= 0.02), 1- and 3-week (3%; p= 0.01), and 3- and 6-week active SLR test scores (7%; p= 0.011); and baseline and 1-week (-2.6%; p= 0.03), 1- and 3-week (8.34%; p= 0.01), and 3- and 6-week passive SLR test scores (5.3%; p= 0.025).

CONCLUSION

Myofascial trigger point therapy with an inflatable ball relieved pain and improved physical function in the elderly with CNSLBP.

Instrument-assisted soft tissue mobilization increases myofascial trigger point pain threshold

BACKGROUND

A myofascial trigger point (MTrP) has been defined as a hyperirritable, palpable nodule in a skeletal muscle. The signs and symptoms of a MTrP include muscle pain, weakness, and dysfunction. MTrPs are common problems associated with soft tissue pathology. Having an intervention to decrease MTrP pain can be clinically valuable.

PURPOSE

To determine if a series of six instrument-assisted soft tissue mobilization (IASTM) treatments rendered over three weeks would influence the pressure pain threshold (PPT) of a myofascial trigger point (MTrP).

METHODS

Randomized, control trial of healthy individuals (n = 29) with MTrPs in the upper trapezius muscle. The intervention was six IASTM treatments rendered over three weeks. Each treatment included 1 min of sweeping with the GT-1/HG-2 (handle bar), 1 min of swivel with the knob of the GT-1/HG-2 directly over the MTrP, 2 min of fanning with the GT-4/HG-8 (convex single bevel), and concluded with 1 min of sweeping with GT-1/HG-2. The outcome measure used a dolorimeter to compare PPT before and after three weeks in both the treatment and control groups.

RESULTS

Paired t-test for PPT pre-test and post-test of the control and treatment groups were p = 0.42159 and p = 0.00003, respectively. A one-way ANOVA of the control and IASTM groups revealed a statistically significant difference (p < 0.0001). The power calculation was greater than 0.99.

CONCLUSIONS

A 5-min intervention using three IASTM techniques can effectively increase the PPT of a MTrP in six treatments over a three-week period of time.

The effects of aroma massage and foot bath on psychophysiological response in stroke patients

[Purpose] This research aimed to examine the effects of back massage and foot bath with blended essential oil on psychophysiological response in stroke patients. [Subjects and Methods] The subjects were 14 adult stroke patients randomly divided into the experimental group (7 patients) and the control group (7 patients). Physical and psychological stress, mood state and sleep satisfaction was measured using evaluation instruments and body temperature was measured with infrared thermography (T-1000). [Results] Measurements included physical and psychological stress, and mood state of the experiment group became significantly lower than that of the control group. The body temperature and sleeping satisfaction of the experimental group became significantly higher than that of the control group. [Conclusion] The present study suggested that aroma therapy and foot bath that can be used as alternative physical therapy that offers an overall beneficial effect on psychophysiological response such as reduced stress, mood state and increased body temperature, sleeping satisfaction of stroke patients.

Effects of friction massage of the popliteal fossa on blood flow velocity of the popliteal vein

[Purpose] Friction massage (friction) of the popliteal fossa is provided for the purpose of relieving pain related to circulatory disorders by improving venous flow in the lower legs. The purpose of this study is to verify the effects of enhancing the venous flow based on measuring the blood flow velocity of the popliteal vein before and after providing friction to the patients. [Subjects and Methods] Fifteen healthy male university students participated in the study. The Doppler ultrasonography (DU) was used to measure the blood flow velocity of the popliteal vein, in order to verify the effects of enhancing the venous flow by comparing the measured values before and after a friction massage. [Results] The result of comparing the blood flow velocity before and after providing friction showed that there was a significant increase after friction. [Conclusion] This study proved that friction to the popliteal fossa is effectively enhances venous flow by increasing the blood flow velocity in the popliteal vein.

Effects of a skin-massaging device on the ex-vivo expression of human dermis proteins and in-vivo facial wrinkles

Mechanical and geometrical cues influence cell behaviour. At the tissue level, almost all organs exhibit immediate mechanical responsiveness, in particular by increasing their stiffness in direct proportion to an applied mechanical stress. It was recently shown in cultured-cell models, in particular with fibroblasts, that the frequency of the applied stress is a fundamental stimulating parameter. However, the influence of the stimulus frequency at the tissue level has remained elusive. Using a device to deliver an oscillating torque that generates cyclic strain at different frequencies, we studied the effect(s) of mild skin massage in an ex vivo model and in vivo. Skin explants were maintained ex vivo for 10 days and massaged twice daily for one minute at various frequencies within the range of 65–85 Hz. Biopsies were analysed at D0, D5 and D10 and processed for immuno-histological staining specific to various dermal proteins. As compared to untreated skin explants, the massaging procedure clearly led to higher rates of expression, in particular for decorin, fibrillin, tropoelastin, and procollagen-1. The mechanical stimulus thus evoked an anti-aging response. Strikingly, the expression was found to depend on the stimulus frequency with maximum expression at 75Hz. We then tested whether this mechanical stimulus had an anti-aging effect in vivo. Twenty Caucasian women (aged 65-75y) applied a commercial anti-aging cream to the face and neck, followed by daily treatments using the anti-aging massage device for 8 weeks. A control group of twenty-two women, with similar ages to the first group, applied the cream alone. At W0, W4 and W8, a blinded evaluator assessed the global facial wrinkles, skin texture, lip area, cheek wrinkles, neck sagging and neck texture using a clinical grading scale. We found that combining the massaging device with a skin anti-aging formulation amplified the beneficial effects of the cream.

Therapeutic effectiveness of instrument-assisted soft tissue mobilization for soft tissue injury: mechanisms and practical application

This article reviews the mechanism and effects of instrument-assisted soft tissue mobilization (IASTM), along with guidelines for its practical application. IASTM refers to a technique that uses instruments to remove scar tissues from injured soft tissues and facilitate healing process through formation of new extracellular matrix proteins such as collagen. Recently, frequent use of this instrument has increased in the fields of sports rehabilitation and athlete training. Some experimental studies and case reports have reported that IASTM can significantly improve soft tissue function and range of motion following sports injury, while also reducing pain. Based on the previous studies, it is thought that IASTM can help shorten the rehabilitation period and time to return to sports among athletes and ordinary people who have suffered sports injuries. However, few experimental studies of the mechanisms and effects of IASTM have examined, while case reports have accounted for the majority of articles. In the future, the scientific basis of IASTM and its reliability should be provided through well-designed experimental studies on humans. Moreover, IASTM studies that have mostly focused on tendons need to broaden their scope toward other soft tissues such as muscles and ligaments.

Spinal manipulative therapy, Graston technique® and placebo for non-specific thoracic spine pain: a randomised controlled trial

Background

Few controlled trials have assessed the efficacy of spinal manipulative therapy (SMT) for thoracic spine pain. No high quality trials have been performed to test the efficacy and effectiveness of Graston Technique® (GT), an instrument-assisted soft tissue therapy. The objective of this trial was to determine the efficacy of SMT and GT compared to sham therapy for the treatment of non-specific thoracic spine pain.

Methods

People with non-specific thoracic pain were randomly allocated to one of three groups: SMT, GT, or a placebo (de-tuned ultrasound). Each participant received up to 10 supervised treatment sessions at Murdoch University chiropractic student clinic over a 4 week period. The participants and treatment providers were not blinded to the treatment allocation as it was clear which therapy they were receiving, however outcome assessors were blinded and we attempted to blind the participants allocated to the placebo group. Treatment outcomes were measured at baseline, 1 week, and at one, three, six and 12 months. Primary outcome measures included a modified Oswestry Disability Index, and the Visual Analogue Scale (VAS). Treatment effects were estimated with intention to treat analysis and linear mixed models.

Results

One hundred and forty three participants were randomly allocated to the three groups (SMT = 36, GT = 63 and Placebo = 44). Baseline data for the three groups did not show any meaningful differences. Results of the intention to treat analyses revealed no time by group interactions, indicating no statistically significant between-group differences in pain or disability at 1 week, 1 month, 3 months, 6 months, or 12 months. There were significant main effects of time (p < 0.01) indicating improvements in pain and disability from baseline among all participants regardless of intervention. No significant adverse events were reported.

Conclusion

This study indicates that there is no difference in outcome at any time point for pain or disability when comparing SMT, Graston Technique® or sham therapy for thoracic spine pain, however all groups improved with time. These results constitute the first from a fully powered randomised controlled trial comparing SMT, Graston technique® and a placebo.

Massage therapy decreases pain and perceived fatigue after long-distance Ironman triathlon: a randomised trial

QUESTION

Can massage therapy reduce pain and perceived fatigue in the quadriceps of athletes after a long-distance triathlon race (Ironman)?

DESIGN

Randomised, controlled trial with concealed allocation, intention-to-treat analysis and blinded outcome assessors.

PARTICIPANTS

Seventy-four triathlon athletes who completed an entire Ironman triathlon race and whose main complaint was pain in the anterior portion of the thigh.

INTERVENTION

The experimental group received massage to the quadriceps, which was aimed at recovery after competition, and the control group rested in sitting.

OUTCOME MEASURES

The outcomes were pain and perceived fatigue, which were reported using a visual analogue scale, and pressure pain threshold at three points over the quadriceps muscle, which was assessed using digital pressure algometry.

RESULTS

The experimental group had significantly lower scores than the control group on the visual analogue scale for pain (MD -7 mm, 95% CI -13 to -1) and for perceived fatigue (MD -15 mm, 95% CI -21 to -9). There were no significant between-group differences for the pressure pain threshold at any of the assessment points.

CONCLUSION

Massage therapy was more effective than no intervention on the post-race recovery from pain and perceived fatigue in long-distance triathlon athletes.

Massage therapy: understanding the mechanisms of action on blood pressure. A scoping review

Massage therapy (MT) has shown potential in reducing blood pressure (BP); however, the psychophysiological pathways and structures involved in this outcome are unclear. The aims of this scoping review were twofold. (1) To summarize the current knowledge of the mechanisms of action of MT on BP. (2) To highlight the research gaps and challenges that researchers must overcome to further elucidate how MT attenuates BP. A scoping review was conducted to examine the evidence regarding the mechanisms of action of MT on BP. This review included the thematic analysis of 27 publications that considered the influence of MT on BP. Based on this analysis, six potential BP mediating pathways were identified Current theories suggest that MT exerts sympatholytic effects through physiologic and psychological mechanisms, improves hypothalamus-pituitary-adrenocortical axis function, and increases in blood flow, which, in turn, may improve endothelial function. Future study is needed, using more scientifically rigorous methodology, to fully elucidate the mechanism of action of MT.
