[Abstract] Ankle plantarflexor spasticity is not differentially disabling for those who are weak following traumatic brain injury

ABSTRACT

Primary objectives: The main aim of this study was to determine whether the presence of distal lower-limb spasticity had a greater impact on mobility for those who had greater levels of muscle paresis following traumatic brain injury (TBI).

Research design: This was a cross-sectional cohort study of convenience. Seventy-five people attending physiotherapy for mobility limitations following TBI participated in this study. All participants had sustained a moderate–severe TBI and were grouped according to the presence or absence of ankle plantarflexor spasticity for comparison.

Main outcomes and results: The primary outcome measure for mobility was self-selected walking speed and the primary outcome measure for muscle strength was hand-held dynamometry. Secondary outcome measures for mobility and muscle strength were the High-level Mobility Assessment Tool (HiMAT) and ankle power generation (APG) at push-off. Spasticity was quantified with the Modified Tardieu scale. Participants with ankle plantarflexor spasticity (Group 2) had slower self-selected walking speeds. There was no statistically significant effect for Group and plantarflexor strength (p = 0.81).

Conclusion: Although participants with ankle plantarflexor spasticity walked significantly slower than those without, the presence of ankle plantarflexor spasticity did not lead to greater mobility limitations for those who were weak.
