Scapular muscle endurance, shoulder pain, and functionality in patients with rotator-cuff-related shoulder pain: a matched, case-control study

Background Deficiency in scapular muscle endurance (SME) is a risk factor for rotator-cuff-related shoulder pain (RCRSP). However, the exact relationship among SME, pain, and functionality remains unclear. This study aims to compare SME, pain, and functionality in RCRSP patients to those in age-sex-matched healthy controls. Methods Twenty-three patients with RCRSP and 23 age-sex matched healthy controls were included in the study. SME was measured using a 1-kg dynamometer. Self-reported pain level was assessed using a visual analog scale. The Functional Impairment Test-Hand, Neck, Shoulder, and Arm (FIT-HaNSA) was also used to assess functional impairment. Results The control group had higher SME and total FIT-HaNSA scores than the patient group (P<0.05). There was a statistically significant and positive correlation between SME and FIT-HaNSA scores in both groups (P<0.05). Conclusions SME was affected by RCRSP. Pain and functional impairment were correlated with low SME. Level of evidence IV

Genç Milli ve A Milli Tekerlekli Sandalye Basketbol Sporcularında Kuvvet ve Anaerobic Gücün Karşılaştırmalı Çalışması

Objective: The aim of the study was to compare the body composition, anaerobic power and isokinetic muscle strength of the shoulder rotators of the young National and National Junior Male Wheelchair Basketball players. Materials and Methods: A total of 28 male wheelchair basketball players aged between 15 and 31 years participated in the study. The age, height, weight, body mass index, and lean body mass of both the teams were compared, and isokinetic strength testing of the internal shoulder and external rotator muscles was performed at speeds of 60 degrees/s and 180 degrees/s in the scapular plane. The Wingate anaerobic power test (30 s) was performed using an upper body ergometer. The results were compared using the Mann-Whitney U test. Results: There were statistically significantly difference in isokinetic strength and body composition of two teams (p0.05). Conclusion: We believe that this difference in strength originates from the muscle kinetics of wheelchair propulsion.WoSScopu
