Background Shoulder pain is common among patients with musculoskeletal pain and the prevalence of patients with subacromial pain syndrome (SAPS) is high. Despite the high prevalence, there is a lack of an extensive evaluation of the proprioception acuity in patients with SAPS. Knowledge of the proprioceptive deficit would assist clinicians in the proper treatment and may offer an alternative explanation for the mechanisms underlying SAPS, which are poorly understood. Objective To compare the proprioceptive function of the shoulder in patients with SAPS and matched controls. Study Design Matched case‐control study. Setting Physical Functional Rehabilitation Service of an outpatient clinic. Participants A total of 32 consecutive patients with SAPS who sought physical therapy for shoulder pain and 32 healthy participants (control group) matched for age, sex, and handedness. Interventions All participants completed a questionnaire containing sociodemographic information, pain intensity and characteristics, the Numerical Pain Rating Scale, and the Shoulder Pain and Disability Index. Main Outcome Measurements The proprioceptive assessment was performed through kinesthesia, passive joint position sense (PJPS), and the active joint position sense (AJPS). Results The groups showed no statistically significant differences in kinesthesia, PJPS, and AJPS for internal or external rotation. The proprioceptive acuity was not associated with pain intensity or functional disability in patients with SAPS. Conclusions Participants with SAPS did not present proprioceptive deficits in a pain‐free motion of medial and lateral rotation when compared to their matched controls. The proprioceptive deficit may not be involved with the mechanisms underlying SAPS and seems not to interfere with the clinical outcomes of patients with SAPS. Level of Evidence Level III.
