Exploring Muscle Strength, Proprioception, and Pain Duration in Shoulder Impingement Syndrome
Öz
This study aimed to explore how proprioception and muscle strength relate to pain duration in individuals with shoulder impingement syndrome. The study involved 45 participants (15 males and 30 females), aged between 22 and 74 years, all diagnosed with shoulder impingement syndrome and experiencing pain lasting from 1 to 36 months. After assessment of pain duration, muscle strength was measured using a hand-held dynamometer (K-Force Kinvent, 34000 Montpellier, France), and shoulder joint proprioception was assessed with an inclinometer (Goniometer Pro, 5fuf5 Co., New Jersey, USA). All measurements were taken on the affected side with impingement. Pearson's correlation analysis was used to examine the relationship between muscle strength and proprioception with the duration of pain in parametric data, while Spearman's rank correlation coefficient was employed for non-parametric data. The results were evaluated at a significance level of 0.05. At the end of the study, there was no significant correlation found between pain duration and both muscle strength and proprioception (p> 0.05). The study concluded that there is no relationship between muscle strength, proprioception, and the duration of pain in shoulder impingement syndrome. Our findings suggest that when investigating upper extremity disorders with primary outcomes of muscle strength and proprioception, pain duration need not be included in study eligibility criteria. The absence of significant correlations suggests these parameters function independently of how long symptoms have persisted. Further studies are needed to explore the relationship between pain chronicity, strength deficits, and proprioceptive alterations across different painful conditions.
