Investigating the effect of sand training on running mechanics in individuals with anterior cruciate ligament reconstruction and pronated feet.

BACKGROUND: Running on sand could be a method for the rehabilitation of individuals with anterior cruciate ligament reconstruction and pronated feet. However, there is a lack of knowledge about the effects of running on sand on running biomechanics and muscle activities. RESEARCH QUESTION: What is the effect of sand training on running mechanics in individuals with anterior cruciate ligament reconstruction and pronated feet? METHODS: Twenty-eight adult males with anterior cruciate ligament reconstruction and pronated feet were divided into two equal groups (intervention and active control groups). Participants were asked to run at a constant speed of ∼3.2 m/s over an 18 m runway, respectively. Ground reaction forces were recorded using a Bertec force plate. Muscle activities were recorded using a surface bipolar electromyography system. RESULTS: In intervention group but not control group, post-hoc analysis demonstrated significantly longer time-to-peak of impact vertical ground reaction force at post-test than that pre-test (p = 0.047). In intervention group but not control group, post-hoc analysis demonstrated significant decreases of semitendinosus activities during push-off at post-test compared with the pre-test (p = 0.005). SIGNIFICANCE: Sand training improved time-to-peak of ground reaction forces (e.g., time-to-peak of peak of impact vertical ground reaction force) and muscle activities (e.g., semitendinosus activities) in adult males with anterior cruciate ligament reconstruction and pronated feet.

The effects of balance board on the balance parameters in five children with spastic cerebral palsy.

PURPOSE: This study evaluated the effects of an instrumented balance board on the balance parameters in children with spastic cerebral palsy by carrying out a pilot single-group pre-post clinical trial. METHODS: Five children aged 5 to 15 years with spastic diplegia and a Gross Motor Function Classification System level of I or II were included. All participants attended 20 sessions with an instrumented balance board, 45 minutes per session, 3 times a week for 7 weeks. The main outcome measures included the center of pressure excursion, velocity, and overshoot during quiet standing with open and closed eyes. The assessments were performed in the mediolateral and anteroposterior directions at pre- and one week post-intervention. RESULTS: Non-parametric tests showed that the excursion did not change significantly except in the mediolateral direction with eyes closed (p < 0.05). The velocity of the center of pressure improved in both directions and eye conditions (p < 0.05). Also, the maximum velocity decreased with eyes open (mediolateral, anteroposterior, and total) (p < 0.05), while the change was not significant with the eyes closed. The overshoot measurements did not change significantly. CONCLUSION: It is recommended to consider balance board training for improving balance parameters in children with cerebral palsy.

Dextrose prolotherapy versus radial extracorporeal shock wave therapy in the treatment of chronic plantar fasciitis: A randomized, controlled clinical trial.

In the recent years, prolotherapy is increasingly being used in the field of musculoskeletal medicine. However, few studies have investigated its effectiveness in plantar fasciitis (PF). The purpose of this study was to compare the effectiveness of ultrasound-guided dextrose prolotherapy with radial extracorporeal shock wave therapy (ESWT) in the treatment of chronic PF. This randomized controlled trial was conducted on 59 patients with chronic PF. Patients were randomly assigned into two groups receiving three sessions of radial ESWT (29 patients) vs. two sessions of ultrasound-guided intrafascial 2 cc dextrose 20% injection (30 patients). The following outcome measures were assessed before and then six weeks and 12 weeks after the treatments: pain intensity by visual analog scale (VAS), daily life and exercise activities by Foot and Ankle Ability Measure (FAAM), and the plantar fascia thickness by ultrasonographic imaging. The VAS and FAAM scales showed significant improvements of pain and function in both study groups 6 weeks and 12 weeks after the treatments. A significant reduction was noted for plantar fascia thickness at these intervals (all p < .05). The inter-group comparison revealed that except for the FAAM-sport subscale which favored ESWT, the interaction effects of group and time were not significant for other outcome measures. Dextrose prolotherapy has comparable efficacy to radial ESWT in reducing pain, daily-life functional limitation, and plantar fascia thickness in patients with PF. No serious adverse effects were observed in either group. LEVEL OF EVIDENCE: Level I, randomized controlled trial.

A randomized comparative trial of corticosteroid phonophoresis, local corticosteroid injection, and low-level laser in the treatment of carpal tunnel syndrome.

BACKGROUND AND AIMS: Carpal tunnel syndrome is the most prevalent peripheral neuropathy and has a considerable burden on health services. We tried to compare the therapeutic effects of local corticosteroid injection, low-level laser, and corticosteroid phonophoresis in the treatment of carpal tunnel syndrome. SUBJECTS AND METHODS: We performed a randomized clinical trial with three parallel groups. The study was carried out at a University Hospital. In total, 42 participants including 31(73.8%) women were randomly allocated to the treatment groups with equal sizes. We assessed pain, symptom severity and functional status with Boston Carpal Tunnel Questionnaire, and performed median nerve conduction velocity studies. Evaluations were done before the interventions and in the fourth week of study. For the group corticosteroid, under the guidance of sonography, methylprednisolone with lidocaine was injected into the carpal tunnel. For laser therapy, we administered 10 sessions, each lasting 10 seconds. We used topical hydrocortisone acetate gel 10% as the anti-inflammatory agent with phonophoresis, 3 times per week for 10 sessions. RESULTS: Within-group analyses with paired t-test showed that local corticosteroid, laser, and phonophoresis are all effective treatments. Between-group analyses with ANOVA indicated that there were significant differences among the groups after four weeks in terms of pain (p = 0.004), in favor of corticosteroid; and in sensory delay (p = 0.001), in favor of laser. For the Boston Carpal Tunnel Questionnaire and median nerve motor latency, the results were not significant. There was no important side-effect after four weeks of follow-up. CONCLUSION: The three treatments are comparable and beneficial for carpal tunnel syndrome.

Subacromial corticosteroid injection versus subcutaneous 5% dextrose in patients with chronic rotator cuff tendinopathy: A short-term randomized clinical trial.

Aim: The aim of this study is to compare subcutaneous 5% dextrose versus subacromial corticosteroid injection for the treatment of chronic rotator cuff tendinopathy. Methods: We carried out a randomized clinical trial with two parallel groups at a university hospital. Overall, 57 (32 women) were included in two groups of corticosteroid (n = 29) and dextrose (n = 28). The mean pain score was 6.6 (1.0). We used a visual analog scale for pain and goniometry for the range of motion. The measurements were repeated 1 month after the interventions. For corticosteroid, a single injection of triamcinolone and 1% lidocaine, and for dextrose, a mixture of 5% dextrose and 2% lidocaine three times weekly were prescribed. Results: Both interventions were effective in decreasing pain compared to the baseline (both p < 0.001). The difference in pain between the two groups was nearly significant 1-month post-intervention (p = 0.052). The comparison of the two groups in considerable pain reduction (≥2.8) was in favor of dextrose (p = 0.046). The differences in the range of motion were not conclusive. None of the participants reported an important adverse effect. Conclusion: The 5% dextrose treatment is at least as effective as corticosteroid for reducing pain in patients with rotator cuff tendinopathy.

The Prevalence of Pronator Teres among Patients with Carpal Tunnel Syndrome: Cross-sectional Study.

The aim of conducting this study was to determine the prevalence of PTS among patients with carpal tunnel syndrome. The study was conducted from March 2014 to April 2015 in the EDX ward and clinic of physical medicine and rehabilitation at the university hospital; Baqiytallah, a large referral practice and research center in Tehran. We included patients with clinical symptoms and signs of CTS. Clinical assessments were aimed to the diagnosis of CTS and PTS. At the next stage, ultrasound study was performed for the participants with suspected CTS. Sample size calculations were based on the formula: [Formula: see text]. Results showed that 13 (8.8%) patients presented electrodiagnostic, and 27 (18.2%) had clinical manifestations of pronator teres syndrome of which, 17 showed ultrasonic signs of the syndrome. In addition, 2, 7, and 8 out of the 17 patients had mild, moderate, and sever carpal tunnel syndrome, respectively. Age was not significantly different between the patients with, and without pronator teres syndrome (p-value=0.179). Nine participants with pronator teres syndrome were male and there was a significant difference concerning sex (p-value=0.013). There was a good agreement between electrodiagnostic and ultrasound findings (Cohen's kappa coefficient=0.71, p-value<0.0001). Taken together, pronator teres syndrome should be considered as a possibility among patients with carpal tunnel syndrome especially in sever forms. Both electrodiagnostic and sonographic studies are efficient for diagnosing pronator teres syndrome. Men are more prone to develop pronator teres syndrome.

INVESTIGATION OF THE EFFECTIVENESS OF ACUPUNCTURE IN THE TREATMENT OF FROZEN SHOULDER.

BACKGROUND: Adhesive capsulitis is a common disease that causes pain and reduced range of motion, but vague on the shoulder. Woman are affected fewer than men, but there is no known racial or genetic tendency. Most patients with adhesive capsulitis will improve with nonsurgical treatment. Acetaminophen and nonsteroidal anti-inflammatory drugs for pain relief in patients without contraindication are first-line options. Acupuncture considered being safe and effective in reducing pain. The aim of this study was to Investigation of the effectiveness of acupuncture in the treatment of frozen shoulder. MATERIALS AND METHODS: In a controlled clinical trial, patients referred to the Baqiatallah clinic in 91 years with shoulder pain, frozen shoulder diagnosed based on history and physical exam, they have been enrolled. Indicators measured in the study was included the involved joint pain, range of motion and quality of life. Patients, first at baseline, one and a half months later (end of session) and then 3 months after the examination information about each individual entered in the from of questionnaires were pre-determined and data were analyzed by SPSS 17 software. RESULTS: In this clinical trial study total 40 patients with frozen shoulder (20 interference with the acupuncture and 20 people control) study that patients average age 55/54. Age maximum 71 years and minimum 44 years. Acupuncture in the treatment of frozen shoulder with the results achieved in the general case acupuncture may improve shoulder motion in patients. VAS index at three months after treatment compared with the control group had a greater improvement. CONCLUSION: In the case of acupuncture and ultimately improve the overall look of all the movement of flexion and adduction of the shoulder, but the movement has been further improved, VAS index at three months after treatment compared with the control group had a greater improvement and finally, we perform acupuncture as a way to improve shoulder motion in patients with frozen shoulder offered.

The prevalence of carpal tunnel syndrome among long-term manual wheelchair users with spinal cord injury: A cross-sectional study.

CONTEXT: Use of a handrim wheelchair could force the wrist into extreme excursions and encroachment of the median nerve. OBJECTIVE: We performed a study of the prevalence of carpal tunnel syndrome in prolonged wheelchair users. DESIGN AND SETTING: A cross-sectional study was conducted for one year in an outpatient clinic of spinal cord injury. PARTICIPANTS: Patients had traumatic injury at the first thoracic level and below, with time since injury of at least 5 years. OUTCOME MEASURE: The prevalence of carpal tunnel syndrome by history taking, clinical examinations and motor and sensory nerve conduction studies of median nerve performed for both hands. RESULTS: Participants (N = 297) were all male. Mean (SD) age and duration since injury were 48 (8.5) and 23 (6.6) years, respectively. A significant difference in median duration of injury based on the severity of the syndrome (P < 0.001), and a significant trend in time since injury for the severity (P (one tailed) < 0.001) were seen. There was a significant difference in the median age among the groups (P = 0.009), and the median increased with the severity (P (one tailed) = 0.001). CONCLUSIONS: Carpal tunnel syndrome is a common side effect of the long time use of wheelchair, and its severity is associated with duration of wheelchair use and age. Alternative methods for wheelchair propulsion should be developed to diminish the likelihood of the syndrome.

Paresthesia and forearm pain after phlebotomy due to medial antebrachial cutaneous nerve injury.

BACKGROUND: Although phlebotomy is a common procedure, there is limited information concerning to documented complications of venipuncture. CASE PRESENTATION: A 45 year old left- handed woman was refered for elecrodiagnostic study with dysesthesia and pain in left medial forearm. She noted these symptoms three weeks after phelebotomy. Electrodiagnostic study showed severe involvement of left side Medial Antebrachial Cutaneous nerve (MAC nerve). CONCLUSION: Phelebotomy is a cause of MAC nerve injury. Electrodiagnostic testing can be helpful in evaluating cases of sensory disturbance after phlebotomy.

Sjögren-Larsson syndrome in two brothers: a case report.

Sjögren-Larsson syndrome is a rare autosomal recessive disorder that was originally recognized in the coexistence of congenital ichthyosis, spastic diplegia or quadriplegia and mental retardation. We recently saw two cases with characteristic features of this rare syndrome. Two brothers aged 21 and 25 years presented with triad of congenital ichthyosis, mental retardation and spastic diplegia. Magnetic resonance imaging showed demyelinating disease in one of these cases. Electrodiagnostic studies were normal in all cases.
