NCT04303078

Brief Summary

The purpose of this study is to examine the underlying mechanisms that contribute to high energy costs for people with cerebral palsy (CP) as they walk. The investigators will characterize the cost landscape of children with CP, quantifying the magnitude of cost (net nondimensional oxygen consumption) associated with walking and common sub-tasks of walking, such as supporting and stabilizing the body.

Outcome Measures

Primary Outcomes (1)

  • Net Nondimensional Oxygen Cost

    Steady-state net nondimensional oxygen consumption while walking on a treadmill. Percent change in oxygen consumption was evaluated between baseline without support and with vertical and lateral support.

    Baseline walking trial with harness on (5-minutes) and support walking trials with vertical or lateral support in harness system (5-minutes)

Secondary Outcomes (7)

  • Three-dimensional Gait Kinematics (Baseline)

    Initial trial without support (5-minutes)

  • Three-dimensional Gait Kinematics (Support)

    Trial with maximum support (5-minutes)

  • Three-dimensional Gait Kinetics (Baseline)

    Initial trial without support (5-minutes)

  • Three-dimensional Gait Kinetics (Support)

    Trial with maximum support (5-minutes)

  • Passive Joint Range of Motion

    One-time research visit (15 minutes)

  • +2 more secondary outcomes

Study Arms (2)

Children with Cerebral Palsy (Cases)

EXPERIMENTAL

Children meeting inclusion/exclusion criteria with a diagnosis of cerebral palsy.

Other: Varying levels of harness support during walking

Typically Developing Children (Controls)

OTHER

Children meeting inclusion/exclusion criteria without a diagnosis of cerebral palsy or other condition.

Other: Varying levels of harness support during walking

Interventions

Participants will complete a standard gait and motion analysis at varying levels of harness support and stabilization (low, moderate, and high levels).
