Sedentary behavior and neck pain in adults: A systematic review and meta-analysis.

Sedentary lifestyle is an imperative risk for musculoskeletal pain. We sought to investigate the association between different types of sedentary behaviors (SBs) and neck pain (NP) among adults. A systematic search was conducted in PubMed, Web of Science, Embase, Scopus, and Google Scholar up to the end of April 2023. The odds ratio (95% CI) was considered as the desired effect size for the association between SBs and the NP. Among 1881 records found by primary search, 46, and 27 reports were included in the qualitative and quantitative analysis respectively. All included studies qualified as good or fair. Our results indicated that SB is a risk factor for NP among adults (OR = 1.5, [1.29, 1.76]). Computer and mobile phone use were also found to be considerable risk factors for NP (OR = 1.3, [1.12, 1.53], and OR = 2.11, [1.32, 3.42] respectively). However, sitting time showed an insignificant association with NP (OR = 1.33, [0.86, 2.07]). Subgroup analysis revealed that SBs are a significant risk factor for NP among university students (OR = 1.58, [1.27, 1.97]), but the association among office workers was marginally insignificant (OR = 1.36, [0.98, 1.89]). According to the meta-regression results, the male gender was found to increase the risk of NP. Meanwhile, Egger's test revealed the presence of publication bias (p-value <0.0001). A sedentary lifestyle as well as computer and mobile phone use is associated with a considerable risk of NP among adults, especially university students. Further, longitudinal studies are needed to better clarify the causality relationships.

Effectiveness of extracorporeal shockwave therapy for chronic Achilles tendinopathy: A randomized clinical trial.

BACKGROUND: In this study, we aimed to evaluate the effectiveness of extracorporeal shockwave treatment (ESWT) on pain and ankle-hindfoot scale of the American Orthopedic Foot and Ankle Society (AOFAS) score of patients with chronic Achilles tendinopathy (AT). MATERIALS AND METHODS: In this double-blind clinical trial, 43 patients with chronic AT were selected and randomly allocated in two groups to receive a basic treatment with ESWT or sham SWT (radial and focused shock waves, four sessions once a week for 4 weeks). AOFAS and pain scores for each patient were recorded at baseline (before intervention), immediately after intervention, and 4 and 16 weeks after intervention using AOFAS and visual analog scale (VAS) scaling method. RESULTS: A total of 43 patients (22 ESWT and 21 sham SWT) were participated in this study. Both groups improved during the treatment and follow-up period. The mean VAS score decreased from 7.55 to 3 in the intervention group and from 7.70 to 4.30 in the sham SWT group. Mean AOFAS and VAS scores were significantly different between ESWT and no ESWT groups at 16 weeks of follow-up (P = 0.013) (P = 0.47). There was no significant difference in terms of AOFAS and VAS scores between both the groups in the other follow-up times. CONCLUSION: Overall, ESWT causes decrease in VAS score and increase in AOFAS score. However, due to the small sample size, the results were not statistically significant. It is recommended to plan more interventional studies with larger sample size in the future.

Effects of aerobic exercise on hematologic indices of women with rheumatoid arthritis: A randomized clinical trial.

BACKGROUND: To investigate the effects of moderate aerobic exercise on the hemoglobin, hematocrit, and red blood cell (RBC) mass of women with rheumatoid arthritis (RA). MATERIALS AND METHODS: This randomized clinical trial was conducted at the Specialized Clinic of Physical Medicine and Rehabilitation, Al-Zahra Hospital of Isfahan, during a 4-month period in 2014. We included patients with RA who did not have any malignancy and hematologic disorder. Two groups - one group receiving aerobic therapy along with medical therapy (N = 16) and the other group receiving medical therapy alone (N = 17) both for a period of 8 weeks. The levels of RBC mass, Hb, and HCT were measured before and after the intervention. The changes in these parameters were compared between the two study groups. RESULTS: There was no significant difference between the two study groups regarding the baseline characteristics. The aerobic exercise resulted in increased RBC mass (P < 0.001), Hb (P < 0.001), and HCT (P < 0.001). However, those who received medical therapy alone did not experience any significant changes in these parameters. We found that the RBC mass (P = 0.581), Hb (P = 0.882), and HCT (P = 0.471) were comparable between the two study groups after 8 weeks of intervention. CONCLUSION: Although the aerobic exercise results in increased Hb, HCT, and RBC mass in patients with RA, the increase was not significant when compared to that in controls. Thus, the increase in the HB, HCT, and RBC could not be attributable to aerobic exercise.

A randomized clinical trial on comparison of corticosteroid injection with or without splinting versus saline injection with or without splinting in patients with lateral epicondylitis.

BACKGROUND: Lateral epicondylitis is a common problem affecting 1-3% of the population. There has been much debate about the best treatment modality for this condition. There is, however, no conclusive evidence in support of any of the proposed treatment modalities. In this trial, we have studied the effect of corticosteroid injection (with or without splinting) with normal saline injection (with or without splinting). MATERIALS AND METHODS: In this double-blind, randomized clinical trial, individuals were randomly assigned to either of four treatment groups and received either 40 mg depomedrol injection alone, 40 mg depomedrol injection with splinting, normal saline injection alone, or normal saline injection with splinting. They were evaluated using the visual analog scale (VAS) at weeks 2, 4 and 24 and with the Oxford elbow scale (OES) at 24 weeks. RESULTS: A total of 79 patients were participated in the study. The corticosteroid injection groups had better pain relief as measured by VAS at 2 and 4 weeks compared with the two saline injection groups. Mean VAS difference at week 0 versus week 2 was 4.5 ± 0.9 and 2.8 ± 0.6 in corticosteroid injection groups and saline injection groups respectively (P < 0.01) but at 24 weeks, there was only moderate benefit reported for the group which received steroid injection and splinting (P < 0.01) compared to the saline injection groups. The saline injection groups reported better improvement in OES scores (20.1 ± 3.7) at the end of the trial compared corticosteroid injection groups (16.1 ± 2.9) (P < 0.05). CONCLUSION: Our results indicate that despite the clear pain reduction benefit associated with steroid injection in short term, this benefit in comparison with normal saline injection fades by the 24(th) week of follow-up.

Long-term effect of extracorporeal shock wave therapy on the treatment of chronic pelvic pain syndrome due to non bacterial prostatitis.

BACKGROUND: There is limited evidence about the chronic pelvic pain syndrome (CPPS) treatment by shockwave therapy, and the aim of this study was to evaluate the effect of extracorporeal shockwave therapy on CPPS due to non bacterial prostatitis in a long-term period. MATERIALS AND METHODS: In a follow-up survey, 40 patients with CPPS (that were randomly distributed into the treatment or sham groups were evaluated at 16, 20, and 24 weeks. In the treatment group, patients were treated by extracorporeal shock wave therapy (ESWT) once a week for 4 weeks by a protocol of 3000 impulses, 0.25 mJ/m(2) and 3 Hz of frequency. 0.05 mJ/m(2) were added in each week. In the sham group, the same protocol was applied, but with the probe being turned off. The follow-up assessments were done by visual analog scale for pain and National Institutes of Health-developed Chronic Prostatitis Symptom Index (NIH-CPSI). Data were compared using independent t-test or analysis of variences. RESULTS: Three patients did not complete the study protocol, 37 patients were evlauated (19 patients in treatment and 18 patients in the sham group). At week 24, the mean of pain score, urinary score, quality-of-life and NIH-CPSI score between two groups were not statistically different. CONCLUSION: Although, ESWT therapy as a safe and effective therapy in CPPS in short-term follow-up has been established, its long-term efficacy was not supported by this study.

Aerobic exercise improves signs of restless leg syndrome in end stage renal disease patients suffering chronic hemodialysis.

BACKGROUND: Restless leg syndrome (RLS) is one of the prevalent complaints of patients with end stage renal diseases suffering chronic hemodialysis. Although there are some known pharmacological managements for this syndrome, the adverse effect of drugs causes a limitation for using them. In this randomized clinical trial we aimed to find a nonpharmacological way to improve signs of restless leg syndrome and patients' quality of life. MATERIAL AND METHODS: Twenty-six patients were included in the study and divided into 2 groups of control and exercise. The exercise group used aerobic exercise during their hemodialysis for 16 weeks. The quality of life and severity of restless leg syndrome were assessed at the first week of study and final week. Data were analyzed using SPSS software. RESULTS: The difference of means of RLS signs at the first week of study and final week was -5.5 ± 4.96 in exercise group and -0.53 ± 2.3 in control group. There was not any statistical difference between control group and exercise group in quality of life at the first week of study and final week. CONCLUSIONS: We suggest using aerobic exercise for improving signs of restless leg syndrome, but no evidence was found for its efficacy on patient's quality of life.

Evaluation of Ulnar neuropathy on hemodialysis patients.

BACKGROUND: Ulnar nerve entrapment at the elbow is the second most common upper extremity nerve involvement after median nerve involvement at the wrist or carpal tunnel syndrome (CTS) considering the frequency of occurrence in the upper limb with variable causes. Hemodialysis, because of elbow positioning during dialysis, upper extremity vascular-access, and underlying disease is one cause of ulnar entrapment. This study considers evaluating the effect of elbow positioning on ulnar involvement prevalence during dialysis. MATERIALS AND METHODS: This cross-sectional study started in June 2011 and completed in December 2011. The patients receiving dialysis with at least one symptom or sign of ulnar nerve involvement underwent nerve conduction studies. Electromyography testing (EMG) performed to confirm the ulnar neuropathy. To review the ulnar nerve, patients must be in supine position with arm in 90° abduction and elbow in 135° flexion. We stimulated the ulnar nerve at three different points, including 6 cm above and 4 cm below the elbow and over the wrist. According to the electrophysiological data, the intensity of nerve entrapment and possibility of associated polyneuropathy determined. RESULTS: Clinically and electrodiagnostically, evidence confirmed that ulnar neuropathy was present in 11 (27.5%) of 40 hemodialysis patients and in 10 (25%) of 40 peritoneal patients (P value: 0.83). Also, the prevalence of median neuropathy in hemodialysis and peritoneal dialysis patients was 14 (35%) and 10 (25%), respectively (P value: 0.33). CONCLUSION: The frequency of median and ulnar neuropathy in hemodialysis patients is more than peritoneal dialysis, but this different is not significant. In addition, comparing sitting position with prolonged elbow flexion and supine position with elbow extension during hemodialysis, recommended doing hemodialysis in later position with using an elbow pad.

Extracorporeal shock wave therapy in patients with plantar fasciitis. A randomized, placebo-controlled trial with ultrasonographic and subjective outcome assessments.

BACKGROUND AND AIM: Results of previous studies have been conflicting on the efficacy of extracorporeal shock wave therapy (ESWT) in the treatment of plantar fasciitis. We evaluated the effects of ESWT on plantar fasciitis in terms of ultrasonographic and subjective evaluations. MATERIALS AND METHODS: In this randomized placebo-controlled trial, patients with plantar fasciitis were assigned to receive ESWT (4000 shock waves/session of 0.2 mJ/mm(2)) in 3 sessions at weekly intervals) or sham therapy (n = 20 in each group). Outcomes were documented by the ultrasonographic appearance of the aponeurosis and by patients' pain scores, performed at baseline and 12 weeks after completion of the therapy. RESULTS: The two groups were similar in baseline characteristics. Over the study period, plantar fascia thickness significantly reduced in the ESWT group (4.1 ± 1.3 to 3.6 ± 1.2 mm, P < 0.001), but slightly increased in the sham group (4.1 ± 0.8 to 4.5 ± 0.9 mm, P = 0.03). Both groups showed significant pain improvement over the course of the study (P < 0.001), though pain scores were significantly more reduced in the ESWT than the sham group (-4.2 ± 2.9 vs. -2.7 ± 1.8, P = 0.049). CONCLUSIONS: Extracorporeal shock wave therapy contributes to healing and pain reduction in plantar fasciitis and ultrasound imaging is able to depict the morphologic changes related to plantar fasciitis as a result of this therapy.

Effects of Transfer Energy Capacitive and Resistive On Musculoskeletal Pain: A Systematic Review and Meta-Analysis:.

The use of transfer energy capacitive and resistive (TECAR) therapy to treat musculoskeletal pain has not been clearly established. Hence, this study was conducted to combine the available results. We searched the main databases, including PubMed (January 1950), Web of Knowledge (January 1945), Scopus (January 1980), and ProQuest (January 1983) until December 2021, to find the related studies. Only those studies were included that assessed the pain in participants who received TECAR therapy and compared it with a control group. Using the random effect model, standardized mean difference (SMD) was calculated at a 95% confidence interval (CI). The differences between patients and control group were -1.04 after four weeks of intervention (95% CI: -1.59 to -0.48, I2=86.9%) and -1.80 after eight weeks (95% CI: -2.15 to -1.46, I2=87%), which was significant (P0.001). The intra-group pain comparison before and after two, four, and eight weeks of TECAR therapy obtained SMD levels of -3.96 (95% CI: -5.28 to -2.65, I2=96.9%), -4.12 (95% CI: -5.98 to -2.26, I2=97.3), and -5.03 (95% CI: -7.23 to -2.83, I2=92.2%), respectively. Despite some limitations, our findings may assist clinicians in decision-making about TECAR therapy for the approach to musculoskeletal pain based on evidence-based medicine.

Effects of Dry Needling and Low-Power Laser for the Treatment of Trigger Points in the Upper Trapezius Muscle: A Randomized Clinical Trial.

Objective: The purpose of this study was to compare the effect of low-power laser therapy, dry needling, and exercise therapy on treating patients with neck and back pain and a diagnosis of the myofascial trigger points in the upper trapezius muscle. Methods: A randomized clinical trial was conducted in Isfahan, Iran, in 2019. The study sample (78 participants) was randomly allocated to 3 groups of 26, including stretching exercises (3 times a day for 2 weeks, control group), low-power laser (3 sessions for 2 weeks, 6 J/cm2, mean power of 100 MW in each point), and dry needling (4 sessions, with 25 × 0.25-mm needles). For all patients, the visual analog scale (VAS), neck disability index (NDI), and shoulder pain and disability index (SPDI) were completed at baseline, immediately, and 1 month after treatment. Results: Final participants in this study (n = 60) consisted of 33 (55%) female patients and 27 (45%) male patients, with a mean age of 51.25 ± 7.94 years. In the exercise group, VAS, NDI, and SPDI scores were not remarkably different in the studied periods (P > .05). Moreover, a notable decrease in VAS, NDI, and SPDI scores were observed in the treatment intervals. However, by excluding the effect of the control group, no substantial difference was observed between the 2 treatments (P > .05). Conclusion: The use of laser therapy and dry needling methods induced a rapid response to pain relief. There was no difference between the 2 forms of treatment in the short term.

Sedentary behavior and neck pain in children and adolescents; a systematic review and meta-analysis.

Background: Sedentary behavior (SB) is considered a risk factor for musculoskeletal pain. We aimed to explore the association of sedentary behavior indicators with neck pain among children and adolescents. Methods: A comprehensive review was performed in different databases until the end of January 2022. Odds ratios (ORs) with 95% confidence intervals were used as desired effect sizes to evaluate the association between prolonged screen time or mobile phone (MP) usage and neck pain risk. Results: Among 1651 records, 15 cross-sectional studies were included in the systematic review, and 7 reports were included in the meta-analysis. Our results suggested a significant relationship between prolonged MP use and neck pain (OR=1.36, 95% CI=1.001-1.85, I2=40.8%, P value for heterogeneity test=0.119). Furthermore, a marginally insignificant association was found between prolonged screen time and neck pain (OR=1.13, 95% CI=0.98-1.30, I2=60.3%, P value=0.01); however, after sensitivity analysis and removing one study, this association became significant (OR=1.30, 95% CI=1.03-1.64). Moreover, a significant association between prolonged sitting time and neck pain was reported in two studies. Conclusion: Available good-quality evidence reveals a significant mild association between sedentary behavior and the risk of neck pain among children and adolescents. However, longitudinal studies with objective measurement tools are warranted. In particular, potential preventive educational programs are suggested for pediatrics to reduce sedentary behavior and neck pain.

Extracorporeal Shockwave Therapy for Chronic Venous Ulcers: A Randomized Controlled Trial.

Background: Chronic venous ulcers (CVUs), demanding specialized care, are still a major socioeconomic problem facing health care systems worldwide. This study's main goal was evaluating the efficacy of ESWT application as an AT in the treatment of wounds for curing CVUs. Materials and Methods: 50 patients presenting with CVUs were divided into two groups of ESWT and control randomly. Then, ESWT was applied one session per week, during four weeks, along with routine CB. The control group also received sham ESWT together with CB. In this respect, pain score, wound size, patient satisfaction and quality of life (QoL) using the Charing Cross Venous Ulcer Questionnaire (CCVUQ) were consequently assessed at baseline, week four, and week eight and then compared between both groups. Results: The findings showed that patients receiving ESWT along with CB had significantly lower pain and were also feeling more satisfied than the cases undergoing CB alone (P<0.05). The significant efficiency of ESWT in improving the healing process of CVUs was further observed (P<0.05). In addition, QoL, assessed by the CCVUQ, was significantly higher in patients receiving ESWT (P<0.05). Conclusion: These findings established that ESWT was a feasible and safe option to treat patients presenting with CVUs in another word,ESWT seems to be a safe and effective adjunct therapy (AT) compared with CB in patients with CVUs.

Association between sedentary behavior and low back pain; A systematic review and meta-analysis.

Background: Sedentariness is a substantial risk for many chronic diseases. We aimed to investigate the correlation of sedentary behavior and its indicators with low back pain (LBP) among adults and children. Methods: Original articles published up to April 28, 2020, using PubMed, Embase, Web of Science and Scopus were evaluated. Odds ratio (OR, 95% CI) was considered the overall effect size for desired associations. Results: We reviewed 49 English articles with analytical observational study design, of which, 27 studies with cross sectional/survey design were retained in the meta-analysis. Among adults, sedentary lifestyle was a considerable risk factor for LBP (OR=1.24, 1.02-1.5); prolonged sitting time (OR=1.42, 1.09-1.85) and driving time (OR=2.03, 1.22-3.36) were the significant risk factors. Sedentary behavior was associated with LBP in office workers (OR=1.23). Moreover, excess weight (OR=1.35, 1.14-1.59) and smoking (OR=1.28, 1.03-1.60) were associated with LBP. Among children, sedentary lifestyle was a remarkable risk factor for LBP (OR=1.41, 1.24- 1.60); prolonged TV watching (OR=1.23, 1.08-1.41) and computer/mobile using and console playing time (OR=1.63, 1.36-1.95) were significant risk factors for LBP. Consumption of coffee, however, has yield conflicting results to be considered as a risk factor. Moreover, the researches on the correlation between sedentariness and high-intensity LBP are scarce and inconclusive. Conclusion: Sedentary behavior, whether in work or leisure time, associates with a moderate increase in the risk of LBP in adults, children and adolescents.

The Effect of Extracorporeal Shock Wave Therapy in the Treatment of Patients with Trigger Finger.

INTRODUCTION: Trigger finger disorder is a sudden release or locking of a finger during flexion or extension. Regarding the complications and disadvantages mentioned for the methods used in the treatment of trigger finger disorder, the aim of this study was to investigate the effect of extracorporeal shock wave therapy in the treatment of patients with trigger finger. METHODS: This study was an interventional study recruiting 19 patients with trigger finger disorder. Evaluation of pain severity, severity of triggering, and functional impact of triggering was carried out using the Visual Analogue Scale, Trigger Finger Score suggested by Quinnell, and Quick-Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, respectively, before intervention, immediately after intervention, and in 6 and 18 weeks after intervention. Each patient was treated with extracorporeal shock wave therapy in three sessions with a 1-week interval. Data were analyzed in Statistical Package for the Social Sciences (SPSS) software using ANOVA to monitor changes in pain severity, severity of triggering, and functional impact of triggering during follow-ups. RESULTS: There were statistically significant differences with regard to reduction of the pain severity, severity of triggering, and functional impact of triggering before intervention, immediately after intervention, and in 6 and 18weeks after intervention (P<0.01). However, the effect of extracorporeal shock wave therapy on reducing severity of triggering immediately after intervention did not yield a statistically significant difference compared to before intervention (P>0.01). CONCLUSION: It seems that extracorporeal shock wave therapy leads to a reduction in pain severity, severity of triggering, and functional impact of triggering. These effects persisted until the 18th week after the intervention. It is recommended to use extracorporeal shock wave therapy in terms of a non-invasive intervention with no significant complications for patients with trigger finger.

Extracorporeal Shock Wave Therapy for Lateral Epicondylitis, Lonely or in Combination with Topical Corticosteroid; Which Approach is Superior?

BACKGROUND: Lateral epicondylitis (LE) is a common musculoskeletal disorder. Although varieties of modalities have been proposed for its treatment, the outcomes are uncertain, and the responses would diminish early by the time passage. The current study was aimed to assess the efficacy of extracorporeal shock wave therapy (ESWT) merely and in combination with topical corticosteroid for the treatment of LE. MATERIALS AND METHODS: In the current double-blinded randomized clinical trial, 70 patients with the diagnosis of LE were randomly allocated to two intervention groups of ESWT merely (control group) (n=35) or ESWT plus topical corticosteroid (intervention group) (n=35). The ESWT was performed weekly for three weeks. Topical clobetasol was utilized within 30 minutes before ESWT for the intervention group, while Vaseline gel was used in a similar pattern for controls. Pain based on a visual analog scale (VAS), handgrip strength (HGS) and the Patient-Rated Tennis Elbow Evaluation (PRTEE) were assessed for the patients before the intervention, following the intervention cessation, and within two months post-intervention. RESULTS: Statistically significant improvement was found following both interventions in terms of pain, HGS, and function (P-value<0.001 for all), while the comparison of the two interventions, ESWT, merely versus in combination with topical clobetasol, revealed insignificant difference (P-value>0.05). CONCLUSION: The findings of our study are in favor of ESWT use either merely or in combination with topical steroids for the treatment of LE, while the comparison of the two techniques revealed insignificant differences.

Evaluation of Relationship between Extensor Digitorum Communis Hoffmann-reflex Latency and Upper Limb Length and Age.

BACKGROUND: The aim of this study was to evaluate the relation between normal values of extensor digitorum communis (EDC) Hoffmann-reflex (H-reflex) latency, upper limb length and age in normal participants, and to determine whether there is any regression equation between them. MATERIALS AND METHODS: In this cross-sectional study, 120 upper limbs of 76 normal volunteers (55 limbs of 34 men and 65 limbs of 42 women) were participated in this study. The onset latency of EDC H-reflex was determined with standard electrodiagnostic techniques and was recorded. RESULTS: The mean EDC H-reflex latency was 15.89 ± 1.41 ms. There was a positive significant correlation between EDC H-reflex latency and upper limb length (r = 0.749, P < 0.0001) and also arm length (r = 0.758, P < 0.0001), but there was a nonsignificant indirect correlation between age and EDC H-reflex latency (r = -0.111, P = 0.227). The relation between H-reflex and sex was not statistically significant (P = 0.46). CONCLUSION: According to our result, there are good predictive values between upper limb length and arm length for the estimation of normal EDC H-reflex latency.

Enhancement of the Effectiveness of Extracorporeal Shock Wave Therapy with Topical Corticosteroid in Treatment of Chronic Plantar Fasciitis: A Randomized Control Clinical Trial.

BACKGROUND: Chronic recalcitrant plantar fasciitis is a disabling condition. We presumed if shock wave could increase the permeability of skin and facilitate penetration of topical corticosteroid through the skin; the combinational therapeutic effect would be stronger than using shock wave alone. The study purpose was to utilize the synergistic effect of shock wave and topical corticosteroid in treatment of plantar fasciitis. MATERIALS AND METHODS: Patients in both groups (n = 40) received four sessions of shock wave with the same protocol at weekly intervals. At 30 min before each session, we used an occlusive dressing of topical clobetasol for the intervention group and Vaseline oil for the control group. Pain severity was assessed with visual analog scale (VAS) and modified Roles and Maudsley score (RMS) at baseline and 1 month and 3 months after intervention. Plantar fascia (PF) thickness was measured with ultrasonography at baseline and 3 months after intervention. RESULTS: One month after intervention, VAS morning showed significant improvement in intervention group (P = 0.006) and RMS showed better improvement in intervention group (P = 0.026). There was no significant difference between the two groups after 3 months in RMS or VAS score. PF thickness was decreased significantly in both groups, but it was not significant between the two groups (P = 0.292). CONCLUSIONS: This combinational therapy yielded earlier pain reduction and functional improvement than using shock wave alone; topical corticosteroid could enhance the effectiveness of shockwave in short-term in the treatment of recalcitrant plantar fasciitis.

Effects of Taping on Pain and Functional Outcome of Patients with Knee Osteoarthritis: A Pilot Randomized Single-blind Clinical Trial.

BACKGROUND: To determine the effects of knee taping in combination with exercise and medical treatment on functional outcome and pain of patients with knee osteoarthritis (OA). MATERIALS AND METHODS: In a randomized single-blinded clinical trial, 36 patients with knee OA were randomly assigned to two study groups. Both groups received exercise and medical therapy for 6 weeks. In addition, the first group (20 patients) received taping in the first 3 weeks. Pain severity (assessed by visual analog scaling), weekly amount of analgesics consumption, timed get up and go test (TUG), and step tests were recorded at baseline, 3 and 6 weeks after the treatment and were further compared between two study groups. RESULTS: There was no significant difference between two groups in pain severity score (P = 0.228), step test score (P = 0.771), TUG test score (P = 0.821) and weekly amount of analgesics consumption (P = 0.873) at baseline. After 3 weeks, weekly amount of analgesics consumption (P = 0.006), pain severity (P < 0.001) was significantly lower in taping group whereas step test score (P = 0.006) was significantly higher in the taping group. After 6 weeks, patients in taping group had significantly lower pain severity (P = 0.011) and higher step test score (P = 0.042). However, there was no significant difference in TUG test score (P = 0.443) and weekly amount of analgesics consumption (P = 0.270) between two groups. CONCLUSION: Therapeutic knee taping may be an effective method for short-term management of pain and disability in patients with knee OA.

Effect of Extracorporeal Shock Wave Therapy on Lower Limb Spasticity in Stroke Patients.

BACKGROUND: This study aims to evaluate the effect of extracorporeal shock wave therapy (ESWT) on lower limb spasticity in stroke patients. METHODS: Twenty-eight eligible patients with ankle plantar flexor spasticity were randomly assigned to two groups. ESWT group received 1 session per week for 3 weeks of ESWT along with oral anti-spastic medications and stretching exercises. The control group received only oral anti-spastic medications and stretching exercises similar to ESWT group. At baseline, weeks 1, 3 and 12, spasticity was assessed and compared between the two groups using Modified Ashworth Scale (MAS), clonus score, passive range of motion (ROM) of joint, pain score, 3-m walk duration and lower extremity functional score (LEFS). Three patients were lost during follow-up; 25 patients completed the study and were analyzed. RESULTS: After one session of ESWT treatment, MAS, pain, ROM and LEFS improved significantly compared to baseline. After three weeks of ESWT treatment, MAS, pain and 3-m walk duration improved significantly compared to week 1. At week 12, MAS, pain, ROM, 3-m walk duration and LEFS improved significantly compared to the control group after controlling baseline values. The trend of decrease in pain score and MAS was significantly different between the groups. The trend of increase in ROM and LEFS was significantly different between the groups. CONCLUSION: ESWT significantly improved lower limb spasticity, pain, passive ROM, 3-m walk duration and LEFS immediately and 12 weeks after treatment. So, ESWT in combination with oral anti-spastic medications and stretching exercises could be useful for improvement of spasticity in stroke patients.

Integrating physical medicine and rehabilitation into the curriculum of Iranian medical students.

PURPOSE: To evaluate the attitude of interns toward Physical Medicine and Rehabilitation (PM&R) and design a PM&R curriculum for medical students with continued medical education programmes and workshops based on the needs and interest of Iranian medical community. METHOD: Eighty questionnaires were distributed to the medical interns on the last day after attendance in the PM&R ward after participating in a one-month outpatient and inpatient course including 12 lectures. RESULTS: Out of 80 participants, 34 (42.5%) were female and 46 (57.5%) were male. All the participants believed participating in a rehabilitation course was necessary; 52 (65%) believed that participating in a separate course of PM&R was necessary, and 28 (35%) believed that rehabilitation of each field of medicine should be presented in its course. A significant percentage (31.4%) of the participants were interested in continuing their education in PM&R specialty. CONCLUSION: The enthusiasm of the medical students towards PM&R is a promising sign toward progress of PM&R in Iran which must be directed through a strong effort of physiatrists through setting up appropriate educational programmes for medical students and continued medical education programme s in the universities.
