Abstract

Aims: The majority of people develop hemiparetic shoulder inferior subluxation following stroke, but the timing of onset is unknown. This study aimed to assess changes in glenohumeral joint centre of rotation (GHJC) during the first six weeks following stroke. Methods: Thirty patients with confirmed diagnosis of stroke (age 65 ± 19 years, 60% female, 40% right side affected) were assessed within 14 days of admission and at six weeks along with matched controls. Bilateral GHJC was determined using a three-dimensional electromagnetic tracking device (ETD). Results: At baseline, GHJC in the stroke group was positioned posteriorly on the hemiparetic side compared to the non-hemiparetic side (mean difference −4.0, 95% confidence interval (CI) − 7.7 to −3.0 mm). In matched controls, GHJC was positioned anterior to the acromion with no significant difference between limbs. At six weeks, the only significant difference occurred for the stroke group; non-hemiparetic GHJC was positioned 12.3 mm (95% CI 2.5–22.1) closer to the acromion compared with control group. Conclusion: Minimal changes in glenohumeral joint positioning occurs early post-stroke. Clinicians should consider changes in glenohumeral joint position for both non- and hemiparetic sides during the early rehabilitation phase following stroke.
