An isokinetic muscle strengthening program for adults with an acquired brain injury leads to meaningful improvements in physical function

Primary objective: To investigate if an isokinetic strength training programme for leg muscles lead to personally meaningful changes in adults with an acquired brain injury (ABI). Research design: A qualitative exploratory design. Methods: Twelve people with ABI participated in pre- and post-intervention face-to-face interviews with open ended questions. Data were initially analysed using a case study research approach exploring individuals experiences and then cross case analysis to determine common themes for the group. Intervention: Twelve-week isokinetic strength training programme for ankle and knee muscles. Outcomes: Participants perceived changes. Results: Thematic analysis determined four main themes arising from the interviews; occupation, vitality, sense of self and personal interactions. Participants reported reductions in impairments as a response to the exercise programme and these changes led to increased function and participation in activities they valued. Also marked improvements in vitality were reported as well as increases in self-esteem and general well-being for many participants. Conclusions: An isokinetic strength training programme resulted in improvements in motor skills and functional abilities that were meaningful for the participants.
