The aim of the study was to investigate if progressive resistance strength training (PRST) can have a beneficial effect on muscle weakness, activity limitations and participation restrictions in adults with traumatic brain injury (TBI). Seven people, six men and one woman, participated in this AB single-system trial. After an 8-week baseline phase, community-based PRST was conducted twice a week for 8 weeks. Changes in maximal isotonic strength (1RM for arm and leg press), activity limitation (maximal gait speed and three items on the Motor Assessment Scale, MAS) and participation restriction (BICRO-39 Scale) were evaluated across the baseline and intervention phases. Leg press strength significantly increased in four participants and arm press strength significantly increased in two participants. Two improved on the sit-to-stand item (MAS). Maximal gait speed and the BICRO-39 Scale scores did not change.
Following a TBI, some adults increased their muscle strength and improved their ability to stand up following a community-based PRST programme.
