Comparison of Shoulder Pain Upper Extremity Function Strength and Endurance in Partial Rotator Cuff Injury

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.

Kısmi Rotator Manşet Yırtığında Omuz Ağrısı, Fonksiyonellik, Kuvvet ve Enduransın İncelenmesi

Öz

Amaç: Çalışmanın amacı, kısmi rotator manşet yaralanması (KRMY) olan bireyler ile KRMY benzeri semptomu olmayan bireyler arasında omuz ağrısı, fonksiyonellik, eklem hareket açıklığı (EHA), endurans ve kuvveti karşılaştırmaktır. Yöntem: Çalışmaya Başakşehir Şehir Hastanesi’nde tedavi gören 40-60 yaş arası KRMY’li 16 birey çalışma grubu, KRMY benzeri semptomu olmayan 16 birey asemptomatik grup olarak alındı. Katılımcılara Görsel Analog Skorlaması (GAS), Constant Murley Skoru (CMS), Zamanlı Fonksiyonel Kol ve Omuz Testi (ZFKOT) ve Basit Omuz Testi (BOT), uygulandı. Gruplar t testi, Mann-Whitney U ve ki-kare analiziyle karşılaştırıldı ve etki büyüklüğü Cohen’s d skoru ile hesaplandı. Bulgular: Çalışma grubunun gece ve hareket sırasındaki ağrısı sırasıyla 8,06±5,68 ve 7,06±2,76 olup bütün parametreler çalışma grubunda istatistiksel olarak anlamlı ve büyük etki düzeyinde olumsuz etkilenmiştir. En yüksek etkilenim gösteren parametreler CMS (p<0,001; Cohen’s d=4,41) ve BOT (p=0,001; Cohen’s d=3,16) parametreleriydi. Çalışma grubunda ortalama omuz fleksiyonu 142º (p<0,001; Cohen’s d=1,76), abdüksiyonu 111º’dir (p<0,001; Cohen’s d=2,68) ve anlamlı bir şekilde kontrol grubuna göre düşüktür. Sonuç: KRMY’de omuzun gece ağrısı hareket sırasındaki ağrıya göre, omuz abdüksiyonu ise omuz fleksiyonuna göre daha şiddetli etkilenmektedir. Çalışma sonuçları klinisyenleri KRMY hastalarının rehabilitasyonunda hedef belirleme ve klinik seyir takibinde destekleyebilir.
