Question	ChatGPT	DeepSeek
Action of serratus anterior muscle	Detailed explanation covering protraction, upward rotation, stabilization, accessory breathing role, innervation, clinical implications, and sports relevance.	Concise summary focusing on protraction, upward rotation, stabilization, innervation, and functional significance. Less detail on biomechanics and clinical applications.
Scapulohumeral rhythm	Thorough breakdown of the 2:1 movement ratio, phases of movement, muscles involved, clinical relevance, and common deviations. Well-structured with cause-effect explanations.	Summarized key points on the 2:1 ratio, movement phases, involved muscles, and clinical importance, but with fewer details on biomechanics and reasoning.
Scapular downward rotation movement impairment syndrome	Comprehensive discussion on pathomechanics, muscle imbalances, assessment, contributing biomechanics, treatment approaches, and prognosis. Includes rehabilitation exercises.	Summarized key aspects, highlighting muscle imbalances, symptoms, diagnostic tests, and general rehabilitation principles but without in-depth assessment techniques.
Upper crossed syndrome	Detailed explanation of postural imbalances, affected muscles, symptoms, common causes, assessment techniques, and specific corrective exercises.	Covers major features, emphasizing tight/weak muscles, causes, symptoms, and broad rehabilitation approaches but lacks detailed assessment methods.
Kinetic medial rotation test	Describes functional assessment of lower limb control during movement, related to knee valgus and ACL injury risk. Explains biomechanics, test procedure, abnormal findings, and clinical applications.	Focuses on shoulder medial rotation assessment, particularly in overhead athletes. Covers procedure, ROM measurement, and clinical relevance.
Management of glenohumeral joint after surgery	Structured post-operative management plan with detailed phase-by-phase rehabilitation, including immobilization, ROM progression, strengthening, neuromuscular control, and return to function.	Summarizes key phases of rehabilitation with emphasis on pain control, ROM, strengthening, and functional recovery but lacks in-depth justifications for specific interventions.
