At GF Strong Rehabilitation Center (GFS), the usual care provided to the ambulatory ABI patients consists of individualized one to one physiotherapy treatment, as well as a high level BT class. Currently, this BT class is a circuit training class that focuses on task-oriented gait exercises. FallProof balance training is a group- based approach that includes multisensory, postural strategy, centre of gravity control and gait pattern training. It was originally developed for older adults with impaired balance; but there is no research on the effectiveness of this approach for ABI patients. The FallProof approach has been introduced to the low level and intermediate level BT class at GFS, for ABI patients with sever and moderate balance impairments. These classes received positive feedback from patients and therapists. Patients reported improved functional mobility and confidence after attending the class. However, there was no functional outcome measurements collected to compare the effectiveness of the previous class and the new FallProof class. We plan to modify the current circuit training high level balance class with the FallProof approach in the spring of 2017. Before introducing the FallProof class, we would like to collect outcome measures with the current BT class for three months, and then collect collect data with the new class for comparison. We would like to determine if a multidimensional group based BT treatment approach is more effective at improving functional outcomes compared to the current practice.
