Randomized Controlled TrialBlind or ultrasound-guided corticosteroid injections and short-term response in subacromial impingement syndrome: a randomized, double-blind, prospective study.
The aim of this study was to compare the accuracy of blind vs. ultrasonography-guided corticosteroid injections in subacromial impingement syndrome and determine the correlation between accuracy of the injection location and clinical outcome. ⋯ Blind injections performed in the subacromial region by experienced individuals were reliably accurate and could therefore be given in daily routines. Corticosteroid injections in the subacromial region were very effective in improving the pain and functional status of patients with subacromial impingement syndrome during the short-term follow-up.

Randomized Controlled TrialAnalgesic effect of transcutaneous electrical nerve stimulation after laparoscopic cholecystectomy.
This study aimed to assess the effect of Transcutaneous Electrical Nerve Stimulation (TENS) on pain, nausea, and emesis in patients submitted to surgery for laparoscopic cholecystectomy. ⋯ Active TENS promoted significant postoperative pain relief, and fewer complaints of nausea and emesis, in patients submitted to laparoscopic cholecystectomy surgery.
