The distribution of positive work and power generation amongst the lower-limb joints during walking normalises following recovery from traumatic brain injury

Abstract

OBJECTIVE: To determine whether better walking performance following recovery from traumatic brain injury (TBI) is attributable to an accentuation of compensatory strategies or an improvement in the way positive work is done and power is generated by the lower-limb joints. SETTING: A large metropolitan rehabilitation hospital. PARTICIPANTS: Thirty-five ambulant people with extremely-severe TBI who were attending physiotherapy for mobility limitations, and a comparative sample of 25 healthy controls (HC). DESIGN: Cross-sectional cohort study with six month follow-up. MAIN MEASURES: Positive work done and average power (i.e. over time) generation by the hip, knee and ankle during stance as wel..
