Low level Laser Therapy versus Ultrasonic therapy for the Treatment of Shoulder Impingement Syndrome A Systematic Review of randomized controlled trials

AbstractBackgroundShoulder impingement syndrome is a common cause of shoulder pain in primary health care settings. Many physical modalities of treatment are available in clinical practice, however there is insufficient evidence on their relative effectiveness. This review compares the effectiveness of Low Level Laser Therapy (LLLT) with ultrasonic therapy.ObjectivesTo assess the effectiveness of LLLT vs. ultrasonic therapy in patients with subacromial impingement syndromeSearch methodsWe searched Cochrane Central Register of Controlled Trials (CENTRAL) on the Cochrane Library, MEDLINE (Pubmed), Embase, Scopus. We searched trials registries on ClinicalTrials.gov (www.ClinicalTrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) Search Portal (apps.who.int/trialsearch/). We also hand-searched reference lists of all included primary studies, relevant conference proceedings and academic literature, and relevant systematic reviews (both Cochrane and non Cochrane), to identify additional studies missed from the original electronic searches (e.g., unpublished or in press citations). We did not use date or language restrictions.Selection criteriaRandomized controlled trials comparing LLLT vs. US therapy in adult patients with subacromial impingement syndrome.Data collectionTwo authors independently assessed trial quality and extracted data. We contacted study authors for additional information. We collected our primary outcomes information from the trials a...
