NCT04142671

Brief Summary

This study evaluates the efficacy of a gait modification intervention using real-time biofeedback on reducing the knee joint loading in Alkaptonuria patients during treadmill walking. It will also assess whether the individualised adopted gait modification can be retained without feedback and during over ground walking.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline 3D knee joint moment impulse after intervention

    This represents the knee joint load during walking measured from kinematic and kinetic data obtained during the 3D gait analysis

    At baseline and immediately after the intervention

Secondary Outcomes (4)

  • Change from baseline joint angles after intervention

    At baseline and immediately after the intervention

  • Change from baseline joint moments after intervention

    At baseline and immediately after the intervention

  • Change from baseline joint powers after intervention

    At baseline and immediately after the intervention

  • Knee injury and Osteoarthritis Outcome Score

Study Arms (1)

Individualised Gait Modification Intervention

EXPERIMENTAL

Patients will carry out several walking trials to test the efficacy of an individualised gait modification intervention. Pre-intervention over ground walking, pre-intervention treadmill walking, intervention treadmill walking with real-time biofeedback on their knee loading, intervention treadmill walking with no feedback, and post-intervention over ground walking.

Other: Individualised gait modification intervention

Interventions

An individualised gait modification intervention to reduce knee joint loading. Knee joint loading will be presented in real-time during treadmill walking. A 10% reduction of each patients baseline knee loading will be used as a target threshold along with visualisation of the history of 5 previous steps. Patients are encouraged to determine their own gait modification strategy that is most efficient for them. Previous examples of gait modifications that mechanically reduce knee loading will be presented to them.
