DALLAS — In this video from the Orthopaedic Research Society Annual Meeting, Alexis K. Nelson spoke about force and muscle activation for external rotation after reverse shoulder arthroplasty in patients with teres minor deficiency.
“Teres minor deficient groups showed greater muscle activations in the moderate neutral position compared to the abduction [position]; however, [they showed] greater force-producing capability in the abduction position compared to the moderate neutral [position],” she said.
“For clinical relevance, we found that placing your arm in a moderate neutral position or abduction position does affect which muscle groups are being activated,” Nelson said, noting, “Clinical care should include that within the patient population rehabilitation post-RSA in a specific teres minor-deficient patient population.”
