Which physical assessment technique is useful for evaluating scapular dyskinesia?

• A. Visual inspection with static posture assessment
• B. Dynamic motion analysis during shoulder movements
• C. Palpation of the rotator cuff muscles
• D. Measurement of shoulder range of motion

Answer: (B)

Dynamic motion analysis during shoulder movements is the most suitable technique for evaluating scapular dyskinesia because it allows for real-time observation of scapular mechanics in conjunction with shoulder joint motions. This assessment provides insight into how the scapula moves during various activities, which is essential for identifying any abnormal motion patterns or imbalances. Scapular dyskinesia often manifests during dynamic activities such as reaching, lifting, or overhead movements, making this method crucial for assessing its impact on shoulder function.

While other techniques like visual inspection can offer a snapshot of the static position, they may not capture the complexities of motion and movement dynamics that are pivotal for diagnosing dyskinesia. Palpation of the rotator cuff muscles primarily assesses muscle tenderness or strength but does not provide insight into scapular motion patterns. Additionally, measuring shoulder range of motion can indicate limitations or restrictions but does not directly assess how the scapula is functioning or moving in relation to the humerus. Thus, dynamic motion analysis is integral for comprehensive evaluation and understanding of scapular dyskinesia.
