Pulsed Shortwave Diathermy and Joint Mobilizations for Achieving Normal Elbow Range of Motion After Injury or Surgery With Implanted Metal: A Case Series

摘要

Context: Regaining full, active range of motion (ROM) after trauma to the elbow is difficult. Objective: To report the cases of 6 patients who lacked full ROM in the elbow because of trauma. The treatment regimen was thermal pulsed shortwave diathermy and joint mobilizations. Design: Case series. Setting: University therapeutic modalities laboratory. Patients of Other Participants: Six patients (5 women [83%], 1 man [17%]) lacked a mean active ROM of 24.5 of extension approximately 4.8 years after trauma or surgery. Intervention(s): Treatment consisted of 20 minutes of pulsed shortwave diathermy at 800 pulses per second for 400 microseconds (40–48 W average power, 150 W peak power) applied to the cubital fossa, immediately followed by 7 to 8 minutes of joint mobilizations. After posttreatment ROM was recorded, ice was applied to the area for about 30 minutes. Main Outcomes Measure(s): Changes in extension AROM were assessed before and after each treatment. Once the patient achieved full, active ROM or failed to improve on 2 consecutive visits, he or she was discharged from the study. Results: By the fifth treatment, 4 participants (67%) achieved normal extension active ROM, and 2 of the 4 (50%) exceeded the norm. Five participants (83%) returned to normal activities and full use of their elbows. One month later, the 5 participants had maintained, on average, (mean ± SD) 92% ± 6% of their final measurements. Conclusions: A combination of thermal pulsed shortwave diathermy and joint mobilizations was effective in restoring AROM of the elbow extension in 5 of the 6 patients (83%) who lacked full ROM after injury or surgery.
