Continuous shortwave diathermy with exercise reduces pain and improves function in Lateral Epicondylitis more than sham diathermy: A randomized controlled trial.

INTRODUCTION: Lateral epicondylitis or tennis elbow, causes significant pain and disability in the upper extremity. Conservative approaches include using thermal and electrical agents. The aim of this study was to explore the effectiveness of shortwave diathermy on pain, function and grip strength of patients with chronic lateral epicondylitis. A randomized placebo-controlled design with concealed allocation, assessor blinding and intention-to-treat analysis was conducted. METHODS: Fifty patients suffering from lateral epicondylitis for more than 3 months, without any systemic diseases or history of other pathologies, were divided into two groups. In both groups, the patients were instructed to perform specific stretching and strengthening exercises. In addition, the patients in the experimental group, received 15 min of 40-60 W, continuous short wave diathermy while sham diathermy was applied for the control group. The primary outcome measure was pain and the secondary outcome measures were functional ability and pain free grip strength. Outcomes were assessed at the base line, after the 5th and the 10th session of treatment as well as after 3 months. RESULTS: Mixed ANOVA analysis showed significant improvement in both groups. Meanwhile, there was a significant interaction effect of time and group on all outcome measures implying the greater improvement in pain, function and grip strength in the group receiving real diathermy. CONCLUSIONS: Adding continuous short wave diathermy to a specific regimen of exercises, reduces pain and improves function in patients suffering from chronic lateral epicondylitis more than sham diathermy and exercise.

Low frequency repetitive transcranial magnetic stimulation to improve motor function and grip force of upper limbs of patients with hemiplegia.

BACKGROUND: Stroke is the most common and debilitating neurological disorder among adults, and is a sudden onset of neurological signs caused by brain blood vessels impairments. OBJECTIVES: Some new therapeutic methods focus on the use of magnetic stimulation to produce therapeutic effects by inducing the currents. The aim of this study is to determine the effects of rTMS plus routine rehabilitation on hand grip and wrist motor functions in patients with hemiplegia, and compare with pure routine rehabilitation programs. PATIENTS AND METHODS: In this study, 12 patients with hemiplegia were randomly divided in two groups. Control group, received the rehabilitation program with placebo magnetic stimulation, and the experimental group, received magnetic stimulation with routine rehabilitation program for 10 sessions for three times per week. Pre and post evaluations of treatment performed using Barthel and Fugl-Meyer indices and dynamometers. RESULTS: In the control group, Barthel and Fugl-Meyer indices showed significant improvement (P = 0.01, P = 0.00), while in the experimental group, significant improvement in Barthel and Fugl-Meyer indices and dynamometers has been observed (P = 0.01, P = 0.00, P = 0.007). CONCLUSIONS: rTMS can improve hand muscle force and functions of patients with chronic hemiplegia, while conventional treatment is not effective.

Comparison of the effects of acupuncture and isometric exercises on symptom of knee osteoarthritis.

BACKGROUND: The investigation and comparison of the effects of acupuncture and isometric exercises on pain and quality of life in patients suffering from knee osteoarthritis (OA). OA is the most common form of joint disease and one leading cause of disability in the elderly. The symptoms of OA are pain, morning stiffness, and joint limited motion. Different treatments have been proposed for management of OA, but the results are not clear. We studied the effects of acupuncture and isometric exercises on symptoms of the knee OA. METHODS: Forty patients with knee OA according to, American college of rheumatology criteria were recruited using strict inclusion and exclusion criteria. All the patients were randomly divided into two groups (A and B).The acupuncture group (A) received only acupuncture at selected acupoint for knee pain. The exercise group (B) received isometric exercise of the knee. Each group received treatment 12 sessions for 4 weeks. Evaluating measuring tools were pain intensity and function was measured with knee injury and OA outcome score (KOOS) questionnaire. RESULTS: After treatment, acupuncture and in isometric exercise groups reported that KOOS increased significantly (improvement) in Quality of Life score as shown (P value <0.05). VAS of acupuncture group changed from 7.25 ± 0.91 to 5.41 ± 1.23.In additions, VAS in isometric exercise group changed from 7.85 ± 1.35 to 5.34 ± 1.26. Total KOOS scores have not shown significant difference in comparative with exercise group (P value > 0.11). CONCLUSIONS: Both acupuncture and isometric exercises decrease pain and increase quality of life in patients who suffer from OA.

Diabetic distal symmetric polyneuropathy: effect of low-intensity laser therapy.

Low-intensity laser therapy (LILT) has been considered as a treatment modality in diabetic distal symmetric polyneuropathy (DSP). The aim of this study is to determine the effectiveness of LILT on DSP. We examined 107 subjects with type 2 diabetes for detection of DSP using the Michigan Neuropathy Screening Instrument (MNSI). Seventeen subjects were eligible to be enrolled in the study. Nerve conduction studies (NCS) were performed in all eligible subjects as an objective method to confirm neuropathy. The participants received LILT three times a week for ten sessions. NCSs were reevaluated after completion of the treatment. The absolute changes in NCS parameters were considered to establish the effectiveness of the treatment. Baseline demographics were similar in all participants. The mean differences of NCV parameters were considered for comparison. At the end of the study, the subjects showed a significant increase in neural potential amplitudes (p < 0.05). This study clearly demonstrated a significant positive effect of LILT on improvement of nerve conduction velocity on diabetic distal symmetric polyneuropathy (DSP). This finding supports the therapeutic potential of LILT in DSP.
