Abstract:

Aim: The study aims to compare shoulder pain, functionality, range of motion (ROM), endurance, and strength between individuals with partial rotator cuff injury (PRCI) and individuals without PRCI-like symptoms. Method: The study group of 16 individuals with PRCI aged 40-60 years who were treated at Başakşehir City Hospital, and 16 individuals without PRCI were included as asymptomatic groups. Participants were assessed by Visual Analog Score (VAS), Constant Murley Score (CMS), Timed Functional Arm and Shoulder Test (TFAST), and Simple Shoulder Test (SST). The groups were compared with t-test, Mann-Whitney U, and chi-square analysis. The effect size was calculated with Cohen’s d score. Results: The study group's pain at night and during movement was 8.06 (±5.68) and 7.06 (±2.76), respectively, with all parameters adversely affected at the statistically significant and large efficacy level in the study group. The most affected parameters were CMS (p<0.001, Cohen’s d=4.41) and BOT (p<0.001, Cohen’s d=3.16). The mean shoulder flexion was 142º (p<0.001, Cohen's d= 1.76, and the abduction was 111º (p<0.001, Cohen's d= 2.68) in the study group and significantly lower than in the control group. Conclusion: In PRCI, nocturnal pain of the shoulder is more severely affected than pain during movement, and shoulder abduction is more severely affected than shoulder flexion. The study results may support clinicians in goal setting and monitoring prognosis in the rehabilitation of patients with PRCI.
