Abstract

Background: Joint Hypermobility Syndrome (JHS) symptoms of widespread joint hypermobility and pain, muscle weakness and reduced muscle-tendon stiffness suggest that there may be an impact on gait parameters. Identification of gait abnormalities may inform assessment and management.
Objective: To explore the impact of JHS on gait parameters.
Study design: Cross-sectional design.
Methods: A JHS group of 29 participants (mean age 37.57 (S.D. 13.77) years) was compared to a healthy control group of 30 participants (mean 39.27 (S.D. 12.59) years). Spatiotemporal parameters, joint kinematics and joint kinetics were captured using the Qualisys motion capture system synchronized with a Kistler force platform.
Results: Statistically significant reductions in walking speed, stride length and step length were found in the JHS group, whilst stance and double support durations were significantly increased (p < 0.01). During the swing phase, the JHS group showed significantly less knee flexion (p < 0.01). Reductions hip extensor moment, and knee power generation and absorption were identified in the JHS group (p < 0.01). No other gait parameters were significantly altered.
Conclusion: The JHS group walked more slowly with a kinematic ‘stiffening’ pattern. Hypermobility was not evident during gait. The observed stiffening pattern could be a strategy to avoid pain and improve balance. Impairments in moment and power generation could be related to several symptomatic and aetiological factors in JHS. Clinicians should carefully consider gait in the assessment and management of people with JHS targeting the impairments identified by the current study.
