Standardised 25-Step Traditional Thai Massage (TTM) Protocol for Treating Office Syndrome (OS)

Traditional Thai massage (TTM) is a unique form of whole body massage practiced to promote health and well-being in Thailand since ancient times. The goal of the present study was to create a standardised TTM protocol to treat office syndrome (OS) diagnosed based on the identification of the palpation of at least one so-called myofascial trigger point (MTrP) in the upper trapezius muscle. The new 90 min TTM protocol, which was developed following appropriate review of the literature and in consultation with relevant experts, has 25 distinct steps (20 pressing steps, 2 artery occlusion steps, and 3 stretching steps). Eleven TTM therapists treated three patients each using the new 90 min TTM protocol. All of the therapists reported scores greater than 80% in respect to their satisfaction and confidence to deliver the protocol, and all of the patients gave the treatment a satisfaction score of greater than 80%. The treatment produced a significant reduction in pain intensity measured on a Visual Analogue Scale (VAS), with minimum and maximum values of 0 and 10 cm, of 2.33 cm (95% CI (1.76, 2.89 cm), p < 0.001) and significant increase in pain pressure threshold (PPT) of 0.37 kg/cm² (95% CI (0.10, 0.64 kg/cm²), p < 0.05). The protocol was revised based on the feedback and the results obtained, and the new standardised TTM protocol will be applied in a randomised control trial (RCT) to compare the efficacy of TTM and conventional physical therapy (PT) for treating OS.

The benefits of Shuai Shou Gong (SSG) demonstrated in a Randomised Control Trial (RCT) study of older adults in two communities in Thailand

INTRODUCTION

Shuai Shou Gong (SSG) is a type of Arm Swing Exercise (ASE) developed and practiced especially by older people in China for over one thousand years to maintain physical health and well-being. Until now the potential benefits of SSG have not been investigated in a Randomised Control Trial (RCT).

MATERIALS AND METHODS

Fifty six older women were recruited from each of two urban communities in Khon Kaen, Thailand. One community was randomly assigned as the Exercise Group (mean age 68.3 years, standard deviation 5.6 years) and the other as the Control Group (69.4 years, 4.4 years). The Exercise Group performed SSG for 40 minutes, three days per week for two months, whereas the Control Group maintained their usual daily life. Measurements of Posture (C7 to Wall Distance (C7WD), Standing Height (SH), Flexibility (Back Scratch of Left and Right arms (BSL and BSR) and Chair Sit and Reach of Left and Right legs (CSRL and CSRR), Gait (Timed Up and Go (TUG)), and Cognition (Barthel Activities of Daily Living Index (BADL) and Rosenberg Self Esteem Scale (RSES) questionnaires) were recorded for each group prior to, on day 1, week 4, and week 8 of the SSG training.

RESULTS

The 8 week SSG training course produced a significant interaction between group and time for the combined set of all outcome measures (C7WD, SH, BSL, BSR, CSRL, CSRR, TUG, BADL, and BSES) (Modified ANOVA-Type Statistic (MATS) p-value < 0.001) and for the four categories of Posture, Flexibility, Gait, and Cognition (all Wald-Type Statistic (WTS) p-values < 0.05) and in all cases the changes in the Exercise Group were in the direction predicted to be beneficial. No significant interaction effect between time and group was found after either one session or four weeks of SSG training for any of the categories (all WTS p > 0.05) with significant effects only arising after eight weeks (all WTS p < 0.05). Thus although alterations were shown to be increasingly beneficial over time the minimum period required to produce a statistically significant benefit from performing SSG training was 8 weeks. For the Control Group no significant changes were identified for Posture, Flexibility and Cognition however a significant deterioration was observed in TUG (WTS p = 0.003).

CONCLUSIONS

SSG is a holistic, gentle, rhythmic, whole body sequence of movements that may be readily learned and enjoyed in a group setting and has been confirmed in an RCT study of older adult females to produce significant benefits in Posture, Flexibility, Gait and Cognition.

Different Protocols for Low Whole-Body Vibration Frequency for Spasticity and Physical Performance in Children with Spastic Cerebral Palsy

Background: Whole-body vibration (WBV) is a therapeutic exercise tool that can be used in children with cerebral palsy (CP). A low vibration frequency with different protocols has been suggested, but no optimal dose has been explicitly indicated. We aimed to determine the superiority of a gradually increased 7–18 Hz WBV protocol over a static 11 Hz WBV and the immediate and short-term effects of WBV training on improving spasticity, functional strength, balance, and walking ability in children with spastic CP. Methods: Twenty-four participants with CP (mean age: 11.5 ± 2.9 years) were randomly allocated into protocols of a static 11 Hz vibration frequency group (SVF) or one that increased from a 7 to an 18 Hz vibration frequency (IVF) (n = 12/group). The WBV programmes were completed for 30 min/session/day to identify immediate effects, and the short-term programme then continued for four days/week for eight weeks. Results: Modified Ashworth Scale scores significantly and immediately improved in the IVF group (hip adductor and knee extensor, p < 0.05), and after eight weeks showed significant improvement in the SVF group (ankle plantar flexor, p < 0.05). Within groups, the Five Times Sit to Stand Test (FTSTS), the Time Up and Go Test and the Functional Reach Test significantly improved in the SVF group, whereas only the FTSTS improved in the IVF group (p < 0.05). There were no significant between-group differences at the eight-week postintervention, except reduced spasticity. Conclusions: A protocol of 7–18 Hz WBV seems to offer superior immediate results in terms of improved spasticity; however, a static 11 Hz protocol appears to offer superior results after eight weeks, although the two protocols did not differ significantly in effects on physical performance. This finding may facilitate preparations to normalise muscle tone before functional mobility therapy. The study results may support future studies about the dose-response of WBV frequency.

Responsiveness of the Mini-Balance Evaluation System Test in Type 2 Diabetic Patients with Peripheral Neuropathy

Background

Mini-BESTest is an instrument for assessing the balance impairment; however, the use of the Mini-BESTest in type 2 diabetic patients with peripheral neuropathy is not well documented in the literature. The aim of this study was to examine the responsiveness and the minimal important change (MIC) of the Mini-BESTest after four weeks of the balance exercises.

Methods

A prospective single group pretest-posttest design was applied, and forty-eight type 2 diabetic patients with peripheral neuropathy were participated (mean age of 59.04 ± 7.533 years; 3 males and 45 females). All participants were given an intervention program including foot care and balance exercises (50-minute sessions, three times a week for four weeks). The responsiveness of the Mini-BESTest was determined using two approaches: 1) the distribution-based method evaluating the change scores (pre- and post-intervention), the effect size (ES), the standard response mean (SRM), the standard error of measurement (SEM) and the minimum detectable change (MDC₉₅) and 2) the anchor-based method evaluating the MIC using the Global Rating of Change scale (GRC) as an external criterion.

Results

After the balance exercises treatment, the Mini-BESTest scores significantly improved (p < 0.001) with an ES of 3.9 and SRM of 4.32. SEM was 0.73 and MDC₉₅ was 2.03 points. The area under the receiver operating characteristic (ROC) curve corresponded to 81%. The cutoff point of the Mini-BESTest was ≥5 points corresponding to the GRC ≤3 versus >3 for the discrimination of the Mini-BESTest between improvement and no improvement after exercises.

Conclusion

The Mini-BESTest can be demonstrated as high responsiveness according to the determination of the distribution-based and the anchor-based methods. The MIC of the Mini-BESTest was taken as ≥5 points and could be used as an outcome measure for the discriminated evaluation of type 2 diabetic patients with peripheral neuropathy.

A 6-Week Nine-Square Exercise Programme for Collegiate Athletes with Chronic Ankle Instability: A Randomised Controlled Trial

Background

Individuals with chronic ankle instability (CAI) have poor postural stability, functional limitations and low quality of life. Although nine-square exercise can improve postural control, there is limited evidence demonstrating whether it can function as an alternative CAI rehabilitation programme. This study aimed to determine the effects of nine-square exercise on postural stability and self-reported outcomes in individuals with CAI.

Methods

Eighteen male collegiate athletes with CAI participated in either a 6-week nine-square exercise or a control group (n = 9 per group). At baseline and post-intervention, the participants undertook clinical tests to measures dynamic and static postural control, and self-reported outcomes regarding ankle stability and function.

Results

Within-group differences, the nine-square exercise group experienced improved dynamic postural control (P = 0.004), static postural control (P = 0.001) and self-reported outcomes (P < 0.05). For the control group, only static postural control improved (P = 0.018). Post-intervention, the nine-square exercise group experienced significant improvements in dynamic postural control (P < 0.001), ankle stability (P = 0.002) and functional ability (P < 0.05) relative to the control group.

Conclusion

These findings suggest that the nine-square exercise can offer an alternative rehabilitation programme for improving postural control, self-perceived ankle stability and functional ability in CAI.

Quadriceps Electromyographic Activity in Closed and Open Kinetic-Chain Exercises with Hip-Adductor Co-Contraction in Sedentary Women

BACKGROUND

Different closed and open kinetic-chain exercises with hip-adductor co-contraction have different effects on quadriceps activity. The aim of this study was to investigate the difference in quadriceps activity during the squat (SQ) and knee extension (KE) and straight leg raise (SLR) exercises with and without hip adduction in sedentary women.

METHODS

Twenty-eight sedentary women aged 44.5 ± 8.5 years were recruited. They performed three exercises with and without hip adduction. Surface electromyography (sEMG) activity was measured on the rectus femoris (RF), vastus medialis oblique (VMO) and vastus lateralis (VL) muscles. The levels of sEMG activities of the three muscles were compared among the six exercises using a repeated-measures ANOVA.

RESULTS

The findings showed that RF activity was lowest during the SQ alone and highest during the SLR exercise (p < 0.05 to 0.001). The VMO activity was significantly greater in the SQH than in the five types of exercises (p < 0.05 to 0.001), which led to a significant VMO/VL ratio as well. VL activity increased while the squat with hip adduction and knee extension with hip adduction exercise compared with SQ alone.

CONCLUSION

This study indicates that a closed-chain squat with hip co-contraction can produce the VMO and VMO/VL ratio activity, while an open chain of SLR better activates the RF activity. The findings support the understanding of quadriceps activity in different exercises to be an alternative home-based exercise for physical therapy in women facing muscle weakness.

Prevalence of Static Balance Impairment and Associated Factors of University Student Smartphone Users with Subclinical Neck Pain: Cross-Sectional Study

The aim of this study was to assess the prevalence of static balance impairment in university student smartphone users with subclinical neck pain and identify the associated risk factors. Because of rapid and widespread smartphones use, and the subsequent effect on neck pain in university students, it is essential to determine the prevalence of balance impairment and associated factors in this population. Simple random sampling was completed among eighty-one participants in this cross-sectional study. A self-reported questionnaire, fitted precisely for smartphone users, was used prior to clinical assessment by the Balance Error Scoring System. Both simple and multiple logistic regressions were used to analyze the prevalence of static balance impairment and associated factors. The prevalence of static balance impairment in university student smartphone users with subclinical neck pain was 74.07% (95% CI: 64.32 to 83.82). The significant risk factors were "daily smartphone use ≥ 4 h'' (AOR: 19.24 (95% CI 4.72 to 78.48) p = 0.000), "≥4 years of smartphone use" (AOR: 5.01 (95% CI 1.12 to 22.38) p = 0.035), and "≥7 neck disability index score'' (AOR: 12.91 (95% CI 2.24 to 74.45) p = 0.004). There was a high prevalence of static balance impairment in university smartphone users with subclinical neck pain. University student smartphone users with subclinical neck pain who met at least one of the risk factors should realize their static balance impairment.

Physical Performance Tests in Adult Neck Pain Patients with and without Clinical Myelopathic Signs: A Matched Case-Control Study

Patients with neck pain may experience cervical myelopathy, this may be detected by clinical myelopathic signs, although they did not have any symptom of myelopathy, except having neck pain. Decreasing physical performance is one symptom of cervical myelopathy that can lead to reduced quality of life in the elderly, however, in adult neck pain with clinical myelopathic signs have not been evaluated. Therefore, this research aimed to compare physical performance in two groups of adult patients with neck pain: those with and without clinical myelopathic signs. A total of 52 participants, gender, age, and body mass index (BMI) matched were allocated into 2 groups of 26 subjects with neck pain, those with, and without, clinical myelopathic signs. The grip and release test, nine-hole peg test, ten second step test and foot-tapping test were evaluated. The group of neck pain participants with clinical myelopathic signs exhibited greater impairment in all the tests than the group without clinical myelopathic signs (p < 0.001). Effect sizes (Cohen’s d) were grip and release test: 2.031, nine-hole peg test: 1.143, ten second step test: 1.329, and foot-tapping test: 0.798. Neck pain participants with clinical myelopathic signs demonstrated reduced physical performance. Physical performance tests may need to assessed in adult patients with neck pain who had clinical myelopathic signs.

Translation, cross-cultural adaptation, and psychometric properties of the Thai version of the Identification of Functional Ankle Instability (IdFAI-THAI) questionnaire

BACKGROUND

This study developed a Thai version of the Identification of Functional Ankle Instability (IdFAI-THAI) questionnaire.

METHODS

To determine construct validity, 200 participants with a history of lateral ankle sprain completed the IdFAI-THAI, the Modified Thai Lower Extremity Functional Scale (LEFS), the Visual Analog Scale of Instability (VAS-I), and the Thai Foot and Ankle Ability Measure (FAAM). Eight days later, 100 randomly selected participants refilled the IdFAI-THAI to assess test-retest reliability and internal consistency.

RESULTS

The IdFAI-THAI moderate correlated with the LEFS (r_s = -0.62), the VAS-I (r_s = 0.62), and the FAAM (r_s = -0.63 and -0.69 for the activities of daily living and sports subscales, respectively). The IdFAI-THAI had good test-retest reliability (ICC_2,1 = 0.89) and excellent internal consistency (Cronbach's alpha = 0.94). Ceiling and floor effects were absent.

CONCLUSION

The valid and reliable IdFAI-THAI can identify chronic ankle instability among Thai speakers in clinical and research settings.

The Cut-Off Score of Four Clinical Tests to Quantify Balance Impairment in Individuals with Chronic Ankle Instability

Background

Balance impairment is a common consequence of chronic ankle instability (CAI). This study aimed to assess the discriminative validity of four clinical tests for quantifying balance impairment in individuals with CAI.

Methods

Participants were screened for their balance using the single-leg balance test (SLBT) and were assigned to either the positive or the negative SLBT groups. Fifty-four individuals with CAI (N = 27 per group) were recruited and completed four clinical tests including the foot-lift test (FLT), the time-in-balance test (TIBT), the modified star excursion balance test in the posteromedial (mSEBT-PM) direction and the side-hop test (SHT). The receiver operating characteristics (ROC) curve coupled with Youden index were calculated to determine the optimal cut-off scores of each test.

Results

We found significant differences in balance between groups for all tests, with good to excellent values for the area under the ROC curve (AUC). All four tests reached good to excellent sensitivity and specificity values and had significant cut-off scores to discriminate balance performance among CAI participants.

Conclusion

All four clinical tests can be conducted with their respective cut-off scores to quantify balance impairment in individuals with CAI.

Effects of mechanical bed massage on biochemical markers of exercise-induced back muscle fatigue in athletes: A randomized controlled trial

BACKGROUND

Many previous studies have explored the effects of manual massage on back muscle fatigue, and most of the mechanical massage techniques imitate manual massage. However, it is unknown whether mechanical and manual massage have the same functions for exercise-induced back muscle fatigue.

OBJECTIVE

To investigate the effects of mechanical bed massage on the biochemical markers of exercise-induced back muscle fatigue in male collegiate athletes.

METHODS

Twenty-eight male collegiate athletes who met the experimental criteria were recruited in this randomized controlled trial, and randomly assigned to a mechanical bed massage group (experimental group) or resting group (control group). The subjects performed eight bouts of reverse sit-up in the prone position and received 20 minutes of the intervention. Creatine kinase, blood lactate, and serum cortisol levels were measured at baseline, after fatigue, after intervention, and after 24 hours.

RESULTS

The level of serum cortisol of the control group was significantly higher than that of the experimental group after the intervention (p< 0.05). The comparison of the two groups for blood lactate levels showed no significant differences at any of the measurement time-points (p> 0.05). There was no significant difference in creatine kinase levels immediately after the intervention (p> 0.05), but a significant difference in creatine kinase level was observed between the two groups 24 hours later (p< 0.05).

CONCLUSIONS

Significant differences were observed between mechanical bed massage and rest condition on serum cortisol and creatine kinase for exercise-induced muscle fatigue. Therefore, mechanical bed massage may reduce stress and muscle damage for the athlete after training or competition.

A Screening Tool for Patients With Lumbar Instability: A Criteria-related Validity of Thai Version

STUDY DESIGN

The study is a cross-sectional, diagnostic validity study.

OBJECTIVE

The aim of this study was to examine the performance characteristics and validity of an existing lumbar instability questionnaire as a screening tool for lumbar instability among chronic low back pain (CLBP) patients.

SUMMARY OF BACKGROUND DATA

Lumbar instability is an initial stage of more severe spinal pathology. Early screening for this condition should help prevent more structural damage. To meet this need, the present study developed numerical cutoff scores for the lumbar instability screening tool.

METHODS

Lumbar instability screening tool responses and x-ray assessments were reviewed from a sample of 110 patients with CLBP (aged 20-59 years). Receiver operator curves were constructed to optimize sensitivity and specificity of the tool.

RESULTS

Fourteen (12.73%) patients had radiological lumbar instability. These patients reported a higher mean lumbar instability questionnaire score than those without radiological lumbar instability. A questionnaire score of at least 7 had a sensitivity of 100% (95% CI, 100-100) and a specificity of 26.04% (95% CI = 17.84-34.24) for detecting lumbar instability when compared with x-ray examination. Receiver operator curve analysis revealed the lumbar instability screening had an area under the curve of 0.62 (95% CI, 0.47-0.77).

CONCLUSION

A lumbar instability screening tool total score of at least 7 was ruled out lumbar instability in CLBP patients. This cutoff score may be used as a marker of conservative treatment response. The sample size of patients with lumbar instability in this study was small, which may hinder the reliability of the data. Further studies are needed.

Immediate Effects of Self-Thai Foot Massage on Skin Blood Flow, Skin Temperature, and Range of Motion of the Foot and Ankle in Type 2 Diabetic Patients

Objectives: The purpose of this study was to investigate the immediate effects of self-Thai foot massages (STFMs) on the foot skin blood flow, the foot skin temperature, and range of motion (ROM) of the foot and ankle in type 2 diabetic patients with peripheral neuropathy. Design: A randomized crossover study. Subjects: Twenty five diabetic patients with peripheral neuropathy were recruited. Interventions: Participants were randomly assigned to either STFM or Thai foot massage (TFM) performed by a massage therapist; then, they were switched to the other group after a 1-week washout period. In both groups, the foot massage was performed in a seated position on the dominant lower leg and foot for 25 min. Outcome measures: Before and immediately after treatment, foot skin blood flow, foot skin temperature, and ROM of the foot and ankle were evaluated. Heart rate was measured throughout the treatment. Results: After a single treatment of the massage, foot skin blood flow and ROM of the foot and ankle significantly improved in both groups (p < 0.05). Foot skin temperature did not change in STFM, whereas it significantly increased in TFM. Heart rate significantly increased in STFM, whereas it tended to decrease in TFM. Conclusions: Both STFM and TFM by a massage therapist could improve foot skin blood flow and ROM of the foot and ankle in diabetic patients with peripheral neuropathy. An STFM could be a promising alternative treatment that patients can perform at home.

Progressive decrease in leg-power performance during a fatiguing badminton field test

[Purpose] This study aimed to evaluate the changes in leg-power generation that accompany competitive badminton, as simulated in a badminton field test (FT). [Participants and Methods] Fifteen male badminton players with 1–2 years of experience performed five repetitions of an FT involving rapid and randomly assigned shuttle-run movements between markers distributed around a badminton court. Repetitions were separated by a 1-minute rest period. Peak mechanical power, obtained from the serial vertical jump tests, was used to estimate fatigue and performance reduction. [Results] Decreases in distance and time were significantly different in each of the five FT repetitions while maintaining the same speed for the condition. The peak mechanical power and fatigue index significantly declined. The reduction in the peak mechanical power percentage (11.78–35.49%) was in the acceptable peak mechanical power range for each FT set. These results were confirmed by the significant increase in the participants’ blood lactate concentration levels, the rating of perceived exertion, and heart rate. [Conclusion] Leg-power generation could gradually be decreased in badminton competition as indicated by a badminton field test.

The prevalence and work-related physical factors associated with knee pain in older Thai farmers

[Purpose] The aim of this study was to examine the prevalence of knee pain in older farmers and to identify the associated factors, including the demographic variables, behaviours and physical activity/exercise levels. [Participants and Methods] A cross-sectional survey was conducted among a total of 285 systematically randomized farmers who were 60 years and older. [Results] The results of this study showed that the overall prevalence of knee pain in this population was 54.04% (n=154) based on a self-reported standardized Nordic Musculoskeletal Questionnaire. The highest prevalence of knee pain was 23.9% [95% confidence interval (CI): 17.75 to 30.05%] for two periods of time (within the past 7 days and over past 12 months). The intolerable physical activity risk factors that were significantly associated with knee pain included prolonged walking, standing and side sitting (odds ratio=2.39%, 95% CI: 1.06 to 5.39%). [Conclusion] The results of this study suggested that a high prevalence of knee pain in these older farmers may be particularly associated with sustaining a weight-bearing position.

Characteristics and distributions of myofascial trigger points in individuals with chronic tension-type headaches

[Purpose] To investigate the characteristics and distributions of the myofascial trigger point (TrP) and pressure pain threshold (PPT) of the active TrP in individuals with chronic tension-type headache (CTTH). [Participants and Methods] Fifty-three CTTH patients and 53 age and gender-matched individuals without CTTH (CON) were recruited. The TrPs and tenderness points were first identified by manual palpation, and the PPTs of the active TrPs were determined by using a manual algometer. [Results] The active TrP, latent TrP and tenderness point totals per person in the head, neck, shoulder and upper back in CTTH were 4.3 ± 2.1, 0.6 ± 1.0 and 1.9 ± 1.8, respectively, while those in CON were 0, 0.7 ± 1.5 and 1.9 ± 1.8, respectively. The PPT levels of the active TrPs were 0.7 ± 0.2 to 1.2 ± 0.6 kg/cm² in the muscles of the head, neck, shoulder and upper back. A larger number of active TrPs and lower PPT levels of the active TrPs were found in the head, neck and shoulder regions than in the upper back region. [Conclusion] Lower PPTs of the active TrPs in the head, neck and shoulder regions could influence the individuals with CTTH.

Effects of task-oriented training on upper extremity functional performance in patients with sub-acute stroke: a randomized controlled trial

[Purpose] The present study aimed to determine the effects of a task-oriented training on paretic upper extremity functional performance in patients with subacute stroke. [Participants and Methods] Twenty-eight subacute stroke sufferers (mean age: 50.07, standard deviation 9.31 years; mean time since stroke 11.11, standard deviation 6.73 weeks) were randomly allocated to task-oriented training (n=14) or conventional exercise program (n=14) group. They were trained as a hospital-based, individualized training 1 hour a session, 5 sessions a week for 4 weeks. Wolf Motor Function Test (primary outcome), motor portion of Fugl-Meyer assessment upper extremity, and hand function domain of Stroke Impact Scale were assessed at baseline, after 2 and 4 weeks of training. [Results] All participants completed their training programs. At all post-training assessments, the task-oriented training group showed significantly more improvements in all outcomes than the conventional exercise program group. No serious adverse effects were observed during or after the training. [Conclusion] Task-oriented training produced statistically significant and clinically meaningful improvements of paretic upper extremity functional performance in patients with subacute stroke. These beneficial effects were observed after 2 weeks (10 hours) of training. Future investigation is warranted to confirm and expand these findings.

The prevalence and work-related physical factors associated with knee pain in older Thai farmers

[Purpose] The aim of this study was to examine the prevalence of knee pain in older farmers and to identify the associated factors, including the demographic variables, behaviours and physical activity/exercise levels. [Participants and Methods] A cross-sectional survey was conducted among a total of 285 systematically randomized farmers who were 60 years and older. [Results] The results of this study showed that the overall prevalence of knee pain in this population was 54.04% (n=154) based on a self-reported standardized Nordic Musculoskeletal Questionnaire. The highest prevalence of knee pain was 23.9% [95% confidence interval (CI): 17.75 to 30.05%] for two periods of time (within the past 7 days and over past 12 months). The intolerable physical activity risk factors that were significantly associated with knee pain included prolonged walking, standing and side sitting (odds ratio=2.39%, 95% CI: 1.06 to 5.39%). [Conclusion] The results of this study suggested that a high prevalence of knee pain in these older farmers may be particularly associated with sustaining a weight-bearing position.

An exploration of the relationship between foot skin temperature and blood flow in type 2 diabetes mellitus patients: a cross-sectional study

[Purpose] The current study aimed to investigate the reliability of infrared thermography as a method of determining foot skin temperature, and to determine the relationship between foot skin temperature and blood flow in type 2 diabetes mellitus (DM) patients. [Participants and Methods] Eighty-five patients were recruited and their foot skin temperature and the ankle brachial index (ABI) were measured using infrared thermography and an automated oscillometry, respectively. A correlation between foot skin temperature and blood flow was performed. The patients were screened and classified according to two groups; diabetic peripheral neuropathy (DPN) and non-DPN. Discriminant validity was determined by comparing the foot skin temperature between the two groups. [Results] The test-retest reliability of foot skin temperature was high. A positive correlation was found between foot skin temperature and ABI in both feet. The foot skin temperatures in the DPN group were found to be significant lower when compared with those in the non-DPN group. [Conclusion] Foot skin temperature is an indirect method of evaluating blood flow in the feet of diabetic patients and can be used as a clinical outcome measurement of treatments used to improve blood flow in type 2 DM patients.

Altered postural sway during quiet standing in women with clinical lumbar instability

[Purpose] The current study aimed to investigate the center of pressure, as an indicator of postural sway, to determine any differences between women with clinical lumbar instability and asymptomatic low back pain. [Participants and Methods] Thirty healthy and fifteen clinical lumbar instability participants were measured for their postural sway in the anterior-posterior and medial-lateral directions. The women were tested for postural sway on a force plate in quiet standing and eyes closed. Center of pressure path length and mean velocity in the anterior-posterior and medial-lateral directions and total area of excursion were measured and analyzed for 30 seconds. [Results] Clinical lumbar instability participants showed a significantly increase when compared with healthy participants, in path length and mean velocity in both directions and total area of excursion. [Conclusion] The findings suggest that chronic low back pain patients with clinical lumbar instability have increased postural sway when vision is deprived. The clinical significance of this has not yet been determined but may provide an opportunity for therapy directed at improving balance control in this patient group.

Immediate effects of dynamic sitting exercise on the lower back mobility of sedentary young adults

[Purpose] The aim of this study was to investigate the effects of dynamic sitting exercises during prolonged sitting on the lower back mobility of sedentary young adults. [Subjects and Methods] Seventy-one subjects aged between 18–25 years participated in this study. Following a randomized crossover study design, subjects were randomly assigned to two groups: sitting only and dynamic sitting exercise. The dynamic sitting exercise was a combination of lower back hyperextension and abdominal drawing-in movements which were repeated 6 times in a 1-minute period and performed every 20 minutes during a 2-hour sitting session. Lumbar range of movement was measured with the modified-modified Schober test, and the pain intensity was evaluated using the visual analog scale. [Results] After the experiment, the lumbar range of movement was significantly impaired in the sitting only group; however, it was significantly improved in the dynamic sitting exercise group. There were significant differences in lumbar range of movement of both flexion and extension between the groups. No significant difference in pain intensity between the groups was found. [Conclusion] These results suggest that dynamic sitting exercises during prolonged sitting can prevent decreases in lumbar range of movement in both back flexion and extension following a 2-hour sitting period.

Effectiveness of a back care pillow as an adjuvant physical therapy for chronic non-specific low back pain treatment: a randomized controlled trial

[Purpose] The aim of this study was to investigate the effect of a back care pillow (BCP) on pain, lumbar range of motion (LROM) and functional disability of patients with chronic non-specific low back pain (LBP). [Subjects and Methods] Fifty-two subjects who were aged between 20–69 years old, who presented with LBP of more than 3 months duration with a numerical rating scale (NRS) value of at least 4 were randomly assigned to treatment (BCP) and control (CON) groups. Participants in each group received six sessions of the 30 minutes treatment for two weeks. The BCP group was asked to wear the BCP during the daytime during the study period. Pain, lumbar ROM and functional disability were assessed before and after the 2-week treatment, and at the end of a 12-week follow up. [Results] After the 2-week treatment and 12-week follow up, all outcomes had improved in both groups; the BCP group had maintained the decrease in pain intensity and improved lumbar ROM in the extension position after the 12-week follow up, and showed better improvements in all outcomes at 2 weeks and after the 12-week follow up. [Conclusion] BCP combined with physical therapy had better pain, lumbar ROM and functional disability outcomes than physical therapy alone.

Effects of seated lumbar extension postures on spinal height and lumbar range of motion during prolonged sitting

Prolonged sitting during sedentary work has been reported as a potential risk factor for low back pain. Furthermore, prolonged sitting can result in both reduced spinal height (SH) and lumbar range of motion (LROM). This study compared the effects of no intervention (control) with two recovery postures on SH and LROM (flexion and extension) during prolonged sitting. Twenty-four participants were randomly assigned to three interventions for three consecutive days. The interventions comprised two seated lumbar extension recovery postures (unsupported sustained and supported dynamic lumbar extension postures) and a control. Both interventions facilitated a relatively short recovery period for both SH and LROM. Supported dynamic lumbar extension conditions significantly helped SH recovery, as compared with control condition, after the first recovery posture intervention, and both postures have potential to maintain LROM. However, both postures failed to induce SH recovery over an extended time.

PRACTITIONER SUMMARY

Unsupported sustained lumbar extension and supported dynamic lumbar extension postures may serve as effective and practical methods for reducing rate of SH loss and maintaining LROM. However, these postures should be further examined in various ‘doses’ to define optimal protocol for effectively minimising SH loss over time.

Effect of Kaempferia parviflora Extract on Physical Fitness of Soccer Players: A Randomized Double-Blind Placebo-Controlled Trial

Background

Physical fitness is a fundamental prerequisite for soccer players. Kaempferia parviflora is an herbal plant that has been used in some Asian athletes with the belief that it might prevent fatigue and improve physical fitness. This study aimed to determine the effects of Kaempferia parviflora on the physical fitness of soccer players.

Material/Methods

Sixty soccer players who routinely trained at a sports school participated in a double-blind placebo-controlled trial and were randomly allocated to the treatment group or the placebo group. The participants in both groups were given either 180 mg of Kaempferia parviflora extract in capsules or a placebo once daily for 12 weeks. Baseline data were collected using the following 6 tests of physical performance: a sit-and-reach test, a hand grip strength test, a back-and-leg strength test, a 40-yard technical test, a 50-metre sprint test, and a cardiorespiratory fitness test. All of the tests were performed every 4 weeks throughout the 12-week study period.

Results

The study showed that after treatment with Kaempferia parviflora, the right-hand grip strength was significantly increased at weeks 4, 8, and 12. The left-hand grip strength was significantly increased at week 8. However, the back-and-leg strength, the 40-yard technical test, the sit-and-reach test, the 50-metre sprint test, and the cardiorespiratory fitness test results of the treatment group were not significantly different from those of the placebo group.

Conclusions

Taking Kaempferia parviflora supplements for 12 weeks may significantly enhance some physical fitness components in soccer players.

Effects of thai foot massage on balance performance in diabetic patients with peripheral neuropathy: a randomized parallel-controlled trial

BACKGROUND Peripheral neuropathy is the most common complications of diabetic patients and leads to loss of plantar cutaneous sensation, movement perception, and body balance. Thai foot massage is an alternative therapy to improve balance. Therefore, the purpose of this study was to investigate the effects of Thai foot massage on balance performance in diabetic patients with peripheral neuropathy. MATERIAL AND METHODS Sixty patients with type-2 diabetes were recruited and randomly assigned into either the Thai foot massage or control groups. The Thai foot massage group received a modified Thai traditional foot massage for 30 min, 3 days per week for 2 weeks. We measured timed up and go (TUG), one leg stance: OLS), the range of motion (ROM) of the foot, and foot sensation (SWMT) before treatment, after the first single session, and after the 2-week treatment. RESULTS After the single treatment session, only the Thai foot massage group showed a significant improvement in TUG. After the 2-week treatment, both Thai foot massage and control groups showed a significant improvement of TUG and OLS (P<0.05); however, when comparing between 2 groups, the Thai foot massage group showed better improvement in TUG than the control group (p<0.05). The Thai foot massage group also showed significant improvements in ROM and SWMT after the 2-week treatment. CONCLUSIONS The results of this study suggest that Thai foot massage is a viable alternative treatment for balance performance, ROM of the foot, and the foot sensation in diabetic patients with peripheral neuropathy.

Effects of Thai massage on physical fitness in soccer players

[Purpose] The aim of this study was to determine the effects of Thai massage on physical fitness in soccer players. [Subjects and Methods] Thirty-four soccer players were randomly assigned to receive either rest (the control group) or three 30-minute sessions of Thai massage over a period of 10 days. Seven physical fitness tests consisting of sit and reach, hand grip strength, 40 yards technical agility, 50-meter sprint, sit-ups, push-ups, and VO_{2, max} were measured before and after Thai massage or rest. [Results] All the physical fitness tests were significantly improved after a single session of Thai massage, whereas only the sit and reach, and the sit-ups tests were improved in the control group. [Conclusion] Thai massage could provide an improvement in physical performance in soccer players.

Prevalence and individual risk factors associated with clinical lumbar instability in rice farmers with low back pain

INTRODUCTION

Clinical lumbar instability (CLI) is one of the subgroups of chronic non-specific low back pain. Thai rice farmers often have poor sustained postures during a rice planting process and start their farming at an early age. However, individual associated factors of CLI are not known and have rarely been diagnosed in low back pain. This study aimed to determine the prevalence and individual associated factors of CLI in Thai rice farmers.

METHODS

A cross-sectional survey was conducted among 323 Thai rice farmers in a rural area of Khon Kaen province, Thailand. Face-to-face interviews were conducted using the 13-item Delphi criteria questionnaire, after which an objective examination was performed using aberrant movement sign, painful catch sign, and prone instability test to obtain information. Individual factors such as sex, body mass index, waist-hip ratio, smoking, and number of years of farming experience, were recorded during the face-to-face interview.

RESULTS

The prevalence of CLI in Thai rice farmers calculated by the method described in this study was 13% (age 44±10 years). Number of years of farming experience was found to be significantly correlated with the prevalence of CLI (adjusted odds ratio =2.02, 95% confidence interval =1.03-3.98, P<0.05).

CONCLUSION

This study provides prevalence of CLI in Thai rice farmers. Those with long-term farming experience of at least 30 years have a greater risk of CLI.

The Effectiveness of Thai Exercise with Traditional Massage on the Pain, Walking Ability and QOL of Older People with Knee Osteoarthritis: A Randomized Controlled Trial in the Community

[Purpose] This study investigated the effectiveness of a class- and home-based exercise with massage between Thai traditional and standardized physical therapy (TPT and SPT) in older people with knee osteoarthritis (KOA). [Subjects and Methods] Thirty-one subjects with KOA (aged 50-85 years) in two selected villages were randomly assigned into the TPT or SPT programs. Seventeen TPT subjects received Thai exercise with traditional massage, and 14 SPT individuals performed strengthening exercise with Swedish massage. Both programs consisted of a class with supervision plus home self-care for 8 weeks; the subjects then managed home self-care for 1 year. [Results] After 2 months, the six-minute walk test (6MWT), Western Ontario and McMaster Universities Arthritis Index (WOMAC), and SF-36 testing showed significant improvement in both groups, but the improvement of the TPT group was greater. After 1year, only the score for the 6MWT was greater in the TPT group than in the SPT group. [Conclusion] The TPT program yielded better results for the 6MWT, but, both programs had beneficial effects on the pain, function, and QOL of middle-aged and older patients with KOA in the community setting.

The effects of thoracic manipulation versus mobilization for chronic neck pain: a randomized controlled trial pilot study

[Purpose] To investigate effects of thoracic manipulation versus mobilization on chronic neck pain. [Methods] Thirty-nine chronic neck pain subjects were randomly assigned to single level thoracic manipulation, single level thoracic mobilization, or a control group. The cervical range of motion (CROM) and pain ratings (using a visual analog scale: VAS) were measured before, immediately after and at a 24-hour follow-up. [Results] Thoracic manipulation significantly decreased VAS pain ratings and increased CROM in all directions in immediate and 24-hour follow-ups. The thoracic mobilization group significantly increased in CROM in most directions at immediate follow-up and right and left rotational directions at the 24-hour follow-up. Comparisons between groups revealed the CROM for the manipulation group to increase significantly more than for control subjects in most directions at immediate follow-up and flexion, left lateral flexion and left rotation at the 24-hour follow-up. The CROM for the thoracic mobilization group significantly increased in comparison to the control group in flexion at immediate follow-up and in flexion and left rotation at the 24-hour follow-up. [Conclusion] The study demonstrated reductions in VAS pain ratings and increases in CROM at immediate and 24-hour follow-ups from both single level thoracic spine manipulation and thoracic mobilization in chronic neck pain.

Effects of handicraft sitting postures on lower trunk muscle fatigue

The purpose of this study was to assess trunk muscle fatigue in seated handicraft tasks using surface electromyography (sEMG) and visual analogue scale (VAS) ratings for trunk discomfort, and to assess the relationship of these responses. Twenty-three participants were randomly assigned to assumed crossed-leg and heel sitting postures for 30 min. Normalised median frequency (NMF) slopes for lumbar multifidus (LM) and internal oblique (IO) muscles and VAS ratings were recorded. Results revealed that the crossed-leg posture produced significantly steeper NMF slopes for both sides of the LM and IO muscles than heel sitting. Greater VAS ratings were found in crossed-leg sitting posture than the heel sitting posture. The NMF slopes and the VAS ratings had significant negative correlations for both postures. Findings support heel sitting in handicraft tasks over crossed-leg sitting due to greater trunk muscle fatigue and discomfort during the latter posture. Results support VAS ratings as a complementary method to sEMG for identifying trunk muscle fatigue. Practitioner Summary: Trunk muscle fatigue in handicraft work is a potential risk for low back pain. Based on EMG and discomfort analyses, heel sitting is preferred to crossed-leg posture. Discomfort ratings are consistent with EMG measures in identifying trunk muscle fatigue in such postures.
