Background: Chronic low back pain (CLBP) due to the degenerative intervertebral disk diseases is one of the most common musculoskeletal conditions in contemporary societies. A variety of pharmacological, non-pharmacological and surgical options is available for treatment of CLBP. The use of non-pharmacological methods have drastically increased in recent years, offering fewer complications and expenses. This study was conducted to compare the efficacy of the neuromuscular electrical stimulation (NMES) and electro acupuncture (EAP) with exercise therapy alone in patients with chronic low back pain. Materials and Methods: This was a randomized case-controlled clinical trial. Sixty patients with CLBP were randomly assigned to 3 groups (20 cases each) of the EAP with exercise therapy, NMES with exercise therapy, and exercise therapy only. Severity of pain and disability improvement were assessed using the visual analog scale (VAS) and Quebec back pain disability scale respectively. Results: A total of 66 individuals were enrolled, out of which 6 were excluded due to patients’ lack of cooperation. A significant decline in the amounts of Quebec and VAS was observed in the three groups (p

Background: Knee medial collateral ligament (MCL) sprain is common in athletes, which keeps them away from trainings. Platelet-rich plasma (PRP) injection is used as an adjunct for treatment of musculoskeletal injuries. This study was supposed to define effect of PRP injection on high-grade MCL sprain healing, in comparison to rehabilitation alone. Materials and Methods: This study was performed on 46 healthy athletes with high-grade MCL sprains who came to sports medicine clinic of Taleghani Hospital, Tehran over a one-year period (2017-2018). In first visit injury grade, its location, baseline pain, Lysholm score and joint stability was determined. Participants randomly allocated to 2 groups (n=23), “group A” had 12-week functional rehabilitation and “group B” had the same rehabilitation plus a single PRP injection. At 4-week intervals valgus stress testing, pain and Lysholm scores was reassessed. The scores of 4th, 8th and 12th weeks was compared to the baseline scores. Results: Mean baseline pain score in control and intervention group was 5.09±0.949 and 5.26±0.810 respectively that in the fourth week of study reduced to 1.30±0.765 and 2.43±0.507 (p

Introduction: In recent years, platelet rich plasma (PRP) has been receiving increasing attention for the treatment of soft tissue injuries. These numerous applications have raised a great deal of questions and debate about the effectiveness of this method. This study aimed to determine the efficacy of PRP in improving sports injuries and subsequently throw some light on these controversies. Methods: A systematic review of the literature and meta-analysis of results were undertaken. All related databases, such as PubMed, Cochrane Database of Systematic Reviews, DARE, and EMBASE, were searched on the use of PRP on athletes and in sports medicine. The search was conducted from June 2013 to February 2014. Results: Our search retrieved 905 studies, of which 13 randomized control trials (RCT) met our inclusion criteria for systematic review and meta-analysis. All articles were appraised by Critical Appraisal Skills Program (CASP) checklist for RCT studies. The analysis of the results of pain scores and physical activity/functions did not show any superiority for PRP as opposed to the other options. Conclusions: The meta-analysis showed no more effectiveness for PRP application in sports-related injuries in terms of physical function improvement and pain relief. Therefore, the extensive use of PRP for such injuries should be limited. Well-designed RCTs are needed to support the findings.
