Effects on pain of kinesiology tape in patients with plantar fasciitis: a randomized controlled study

PURPOSE.

Plantar fasciitis is the most frequent cause of heel pain. Custom-made plantar supports are a common treatment solution, while the application of kinesiology tape (KT) can be an effective measure to alleviate pain. The objective was to evaluate the effects of KT on the pain of patients with plantar fasciitis.

METHODS.

Randomized controlled trial including participants with plantar fasciitis. There was an experimental group (n = 17), whose participants underwent a KT treatment, and a control (sham tape) group (n = 17). The pain, measured with a visual analog scale (VAS), was the primary outcome and was assessed daily until the fifth day of wearing the tape and 24 h after removing it. Inferential statistics looked for time, group, and time per group differences with CI at 95%.

RESULTS.

The greatest between-group VAS difference was 3.5 points, and occurred at the 2-day follow-up assessment. Then, pain differences decreased over time until the last assessment point. Statistically significant time, group, and time*group differences were found with p < 0.001.

CONCLUSION.

This study supports that KT is effective in reducing pain in the short term in patients with plantar fasciitis, and more effective than a sham intervention with tape.

Low-intensity shockwave therapy improves baseline erectile function: a randomized sham-controlled crossover trial

Background

Low-intensity shockwave therapy for erectile dysfunction is emerging as a promising treatment option.

Aim

This randomized sham-controlled crossover trial assessed the efficacy of low-intensity shockwave therapy in the treatment of erectile dysfunction.

Methods

Thirty-three participants with organic erectile dysfunction were enrolled and randomized to shockwave therapy (n = 17) or sham (n = 16). The sham group was allowed to cross over to receive shockwave therapy after 1 month.

Outcomes

Primary outcomes were the changes in Sexual Health Inventory for Men (SHIM) score and Erection Hardness Score at 1 month following shockwave therapy vs sham, and secondary outcomes were erectile function measurements at 1, 3, and 6 months following shockwave therapy.

Results

At 1 month, mean SHIM scores were significantly increased in the shockwave therapy arm as compared with the sham arm (+3.0 vs -0.7, P = .024). Participants at 6 months posttreatment (n = 33) showed a mean increase of 5.5 points vs baseline (P < .001), with 20 (54.6%) having an increase ≥5. Of the 25 men with an initial Erection Hardness Score <3, 68% improved to a score ≥3 at 6 months. When compared with baseline, the entire cohort demonstrated significant increases in erectile function outcomes at 1, 3, and 6 months after treatment.

Clinical Implications

In this randomized sham-controlled crossover trial, we showed that 54.6% of participants with organic erectile dysfunction met the minimal clinically important difference in SHIM scores after treatment with low-intensity shockwave therapy.

Strengths and Limitations

Strengths of this study include a sham-controlled group that crossed over to treatment. Limitations include a modest sample size at a single institution.

Conclusions

Low-intensity shockwave therapy improves erectile function in men with erectile dysfunction as compared with sham treatment, which persists even 6 months after treatment.

Dry Needling Adds No Benefit to the Treatment of Neck Pain: A Sham-Controlled Randomized Clinical Trial With 1-Year Follow-up

OBJECTIVE

To examine the short- and long-term effectiveness of dry needling on disability, pain, and patient-perceived improvements in patients with mechanical neck pain when added to a multimodal treatment program that includes manual therapy and exercise.

DESIGN

Randomized controlled trial.

METHODS

Seventy-seven adults (mean ± SD age, 46.68 ± 14.18 years; 79% female) who were referred to physical therapy with acute, subacute, or chronic mechanical neck pain were randomly allocated to receive 7 multimodal treatment sessions over 4 weeks of (1) dry needling, manual therapy, and exercise (needling group); or (2) sham dry needling, manual therapy, and exercise (sham needling group). The primary outcome of disability (Neck Disability Index score) and secondary outcomes of pain (current and 24-hour average) and patient-perceived improvement were assessed at baseline and follow-ups of 4 weeks, 6 months, and 1 year by blinded assessors. Between-group differences were analyzed with a 2-way, repeated-measures analysis of variance. Global rating of change was analyzed with a Mann-Whitney U test.

RESULTS

There were no group-by-time interactions for disability (Neck Disability Index: F_2.37,177.47 = 0.42, P = .69), current pain (visual analog scale: F_2.84,213.16 = 1.04, P = .37), or average pain over 24 hours (F_2.64,198.02 = 0.01, P = .10). There were no between-group differences for global rating of change at any time point (P≥.65). Both groups improved over time for all variables (Neck Disability Index: F_2.37,177.47 = 124.70, P<.001; current pain: F_2.84,213.16 = 64.28, P<.001; and average pain over 24 hours: F_2.64,198.02 = 76.69, P<.001).

CONCLUSION

There were no differences in outcomes between trigger point dry needling and sham dry needling when added to a multimodal treatment program for neck pain. Dry needling should not be part of a first-line approach to managing neck pain. J Orthop Sports Phys Ther 2021;51(1):37-45. doi:10.2519/jospt.2021.9864.

Immediate effects of Mulligan's techniques on pain and functional mobility in individuals with knee osteoarthritis: A randomized control trial

BACKGROUND AND PURPOSE

Mulligan's mobilization with movement was shown to be effective when implemented in multimodal therapy for knee osteoarthritis. However, no study has evaluated the Mulligan's technique in isolation and compared the relative effectiveness with sham-controlled interventions. Hence, the present study examined the immediate effects of Mulligan's techniques with sham mobilization on the numerical pain rating scale (NPRS) and timed up and go (TUG) test in individuals with knee osteoarthritis.

METHODS

Thirty participants (mean age: 55.3 ± 8.3 years) with symptoms at the knee and radiographic diagnosis of knee osteoarthritis were randomized into sham (n = 15) and intervention (n = 15) groups. The intervention (I) group received Mulligan's mobilization glides that resulted in relative pain relief for three sets of 10 repetitions. For the sham (S) group, the therapist's hand was placed over the joint surfaces mimicking the pain-relieving glides, without providing the gliding force. The outcome measures NPRS and TUG were recorded by a blinded assessor pre- and post-intervention.

RESULTS

Statistically significant differences were identified between the groups in post-intervention median (interquartile range) NPRS (I group: 4.00 [2.00-5.00]; S group: 6.00 [4.00-7.00]) and TUG scores (I group: 10.9 [9.43-10.45]; S group: 13.18 [10.38-16.00]) with the intervention group demonstrating better outcomes (p < .05). Within-group, the post-intervention scores of NPRS and TUG were significantly lower (p < .05) compared to the pre-intervention scores in the intervention group. In the sham group, a statistically significant pre-post change was noticed only in the NPRS scores but not in the TUG scores.

CONCLUSION

Mulligan's techniques were effective in improving pain and functional mobility in individuals with knee osteoarthritis. The underlying mechanisms for observed effects must be examined further, as participants reported pain relief following sham mobilization.

A randomized trial of trigger point dry needling versus sham needling for chronic tension-type headache

BACKGROUND

In this randomized, double-blind, parallel-group trial, we aimed to explore the effectiveness of trigger point dry needling in patients with chronic tension-type headache in reducing headache frequency, intensity and duration, and improvement of health-related quality of life.

METHODS

The 168 patients in 2 neurology clinics with chronic tension-type headache. The participants were randomly assigned to one of two treatment groups for dry needling or sham dry needling, delivered in 3 sessions a week for 2 weeks. The 160 patients fulfilled the study requirements. The dry needling was applied in active trigger points located in the musculature of the head and the neck. The patients received dry needling using sterile stainless-steel acupuncture needles of 0.25 × 40 mm and 0.25 × 25 mm dimensions. The sham dry needling procedure was applied into the adipose tissue located at any area where an active trigger point was absent. The primary outcome measurement was the headache intensity. Secondary outcomes were frequency and duration of headache, and quality of life, assessed by the Short Form-36. All outcomes were measured at baseline, at the end of 2-week, and 1-month follow-up period.

RESULTS

In the dry needling group, intensity, frequency and duration of headache, and the scores of Short Form-36 subscales were significantly improved after treatment (P < .05). In the dry needling group, all the effect sizes for headache variables were large.

CONCLUSIONS

The results of this clinical trial suggest that trigger point dry needling in patients with chronic tension-type headache is effective and safe in reducing headache intensity, frequency and duration, and increasing health-related quality of life.

Pulsed electromagnetic field therapy in the treatment of pain and other symptoms in fibromyalgia: A randomized controlled study

Low-energy pulsed electromagnetic field (PEMF) therapy has been suggested as a promising therapy to increase microcirculation, which is of great concern in patients with fibromyalgia. This study evaluated the effectiveness of PEMF therapy on the treatment of fibromyalgia. A group of 108 women with fibromyalgia were allocated to a 12-week treatment period with an active Bio-Electro-Magnetic-Energy-Regulation (BEMER) device and a similar treatment period with an inactive device. Each patient received active and sham treatments in a random order. Pain and stiffness were assessed on a visual analog scale (VAS, scale 0-100 mm), and functional status was assessed by the Fibromyalgia Impact Questionnaire (FIQ). Mean VAS pain scores before the active and sham treatment periods were 66 (SD 22) and 63 (SD 22), respectively. After treatment periods, mean VAS pain scores had decreased significantly in active treatment, -12, 95% CI [-18, -6], and in sham treatment, -11, 95% CI [-17, -5]. Similarly, the decrease in stiffness and FIQ index after both treatments was statistically significant. However, per-protocol analysis showed no differences between active and sham treatments at any of the outcomes. This study demonstrated that low-energy PEMF therapy was not efficient in reducing pain and stiffness or in improving functioning in women with fibromyalgia.

Transcutaneous electrical nerve stimulation and placebo analgesia: is the effect the same for young and older individuals?

Purpose

Placebo analgesia refers to a perceived reduction in pain intensity following the administration of a simulated or otherwise medically ineffective treatment. Previous studies have shown that many factors can influence the magnitude of placebo analgesia. However, few investigations have examined the effect of age on placebo analgesia, and none have done it in the context of electrotherapeutic interventions. The objective of this study is to compare the placebo response induced by sham transcutaneous electrical nerve stimulation (TENS) between young and older individuals, using an experimental heat-pain paradigm.

Patients and methods

Twenty-two young (21–39 years) and 22 older (58–76 years) healthy adults participated in this comparative study. Experimental heat pain was evoked with a thermode (2-min stimulation at a constant individually adjusted temperature) applied on the lumbar region. Participants were asked to evaluate the intensity of their pain using a computerized visual analog scale. Experimental pain was induced before and after an unconditioned placebo intervention (placebo TENS) applied for 25 min.

Results

In young individuals, no significant pain reductions were noted, whereas in older individuals, a statistically significant pain reduction was observed after the placebo stimulation (P<0.01). Between-group analyses revealed that placebo analgesia was greater in older individuals (40% pain reduction) compared with young individuals (15% pain reduction) (P<0.05). However, sham TENS increased heat-pain thresholds in the young group (P<0.01), but not in the older group (P=0.43).

Conclusion

Our results indicate that placebo analgesia is influenced by age, with older individuals showing larger placebo analgesia than young adults. Although these results should be confirmed in clinical pain populations, the current observations bear potentially important consequences for the design of future placebo-controlled trials and for healthcare professionals working with elderly patients.

Kinesio taping or just taping in shoulder subacromial impingement syndrome? A randomized, double-blind, placebo-controlled trial

OBJECTIVE

To verify effects of kinesio taping (KT) in shoulder subacromial impingement syndrome (SIS) when compared to sham taping applied in the same way with KT.

PATIENTS AND METHODS

Patients were randomized as group 1 (n = 21) KT group and group 2 (n = 20) sham-taping group. Taping was applied every three days, three times during the study period. We assessed all the patients at baseline, at the end of the taping period (12th day), and at one-month post-intervention. We assessed pain on the 100 mm visual analog scale (VAS). Shoulder range of motion (ROM), Constant Scores, and Nottingham Health Profile (NHP) scores were evaluated.

RESULTS

Of the 41 participants, 13 were males (32%) and 28 were females (68%). The mean age was 45 ± 15 years (range 20-65 years). We documented a significant decrease in VAS for nocturnal pain, and Constant Score in both groups. The KT group showed additional significant change in NHP pain and physical activity scores.

CONCLUSION

KT and sham taping generated similar results regarding pain and Constant Scores.

A comparative study of pelvic floor muscle training in women with multiple sclerosis: its impact on lower urinary tract symptoms and quality of life

OBJECTIVE

To compare pelvic floor muscle training and a sham procedure for the treatment of lower urinary tract symptoms and quality of life in women with multiple sclerosis.

METHODS

Thirty-five female patients with multiple sclerosis were randomized into two groups: a treatment group (n = 18) and a sham group (n = 17). The evaluation included use of the Overactive Bladder Questionnaire, Medical Outcomes Study Short Form 36, International Consultation on Incontinence Questionnaire Short Form, and Qualiveen questionnaire. The intervention was performed twice per week for 12 weeks in both groups. The treatment group underwent pelvic floor muscle training with assistance from a vaginal perineometer and instructions to practice the exercises daily at home. The sham group received a treatment consisting of introducing a perineometer inside the vagina with no exercises required. Pre- and post-intervention data were recorded.

RESULTS

The evaluation results of the two groups were similar at baseline. At the end of the treatment, the treatment group reported fewer storage and voiding symptoms than the sham group. Furthermore, the differences found between the groups were significant improvements in the following scores in the treatment group: Overactive Bladder Questionnaire, International Consultation on Incontinence Questionnaire Short Form, and the General Quality of Life, and Specific Impact of Urinary Problems domains of the Qualiveen questionnaire.

CONCLUSIONS

The improvement of lower urinary tract symptoms had a positive effect on the quality of life of women with multiple sclerosis who underwent pelvic floor muscle training, as the disease-specific of quality of life questionnaires demonstrated. This study reinforces the importance of assessing quality of life to judge the effectiveness of a treatment intervention.
