Review on: Performance Analysis of HIP Continuous Passive Motion Machine for Post Operative Rehabilitation

This review paper presents an analytical overview of the performance and clinical effectiveness of Continuous Passive Motion (CPM) machines developed for hip rehabilitation following surgical procedures. The study consolidates insights from recent clinical trials, biomechanical assessments, and design evaluations to understand the therapeutic potential and limitations of CPM therapy in post-operative recovery. Evidence indicates that hip CPM devices can enhance early joint mobility, reduce pain, and support tissue healing during the initial recovery phase; however, long-term functional outcomes often align with those achieved through traditional physiotherapy. The paper further emphasizes the importance of ergonomic design, precise alignment, and individualized motion control to optimize therapeutic benefits and minimize discomfort. Despite encouraging results, variations in patient response and the absence of standardized clinical protocols highlight the need for further research. Future advancements integrating sensor technology, feedback systems, and patient-specific customization could transform hip CPM devices into more adaptive and effective rehabilitation tools.
