Summary
Patients with Prader-Willi (PWS) and Down Syndrome (DS) exhibit distinct gait patterns. Down Syndrome patients demonstrate a less stable and physiological gait compared to Prader-Willi Syndrome patients, requiring targeted rehabilitation.
Area of Science:
- Biomedical Engineering
- Clinical Biomechanics
- Human Movement Science
Background:
- Prader-Willi Syndrome (PWS) and Down Syndrome (DS) share common clinical and functional features, necessitating a comparative analysis of their motor deficits.
- Understanding the determinants of motor disability in PWS and DS is crucial for developing effective rehabilitation strategies.
Purpose of the Study:
- To quantitatively measure and compare the gait patterns of individuals with PWS and DS.
- To provide data for the development of evidence-based, deficit-specific, or common rehabilitation strategies for PWS and DS patients.
Main Methods:
- Gait analysis was performed on 19 PWS patients and 21 DS patients using an optoelectronic system and force platforms.
- Kinematic and kinetic parameters during walking were measured and compared to a control group of normal-weight individuals.
Main Results:
- Both PWS and DS groups exhibited cautious, abnormal gait patterns, with DS showing a less stable strategy than PWS.
- DS patients displayed significantly reduced hip and knee flexion and ankle range of motion compared to PWS patients.
- DS had lower ranges of motion in all joints and significantly reduced ankle push-off compared to controls and PWS, with increased hip and ankle stiffness.
Conclusions:
- Down Syndrome is associated with a less physiological gait pattern than Prader-Willi Syndrome.
- Both PWS and DS patients require targeted rehabilitation focusing on hypotonia, muscle strength, and motor control.
- Improving pelvic and hip range of motion is a key specific goal for optimizing gait in DS patients.
