Impact of the BOOST GAIT Program on Gait Recovery and Functional Mobility After Stroke

The overarching goal is to determine if the BOOST GAIT program can improve functional mobility in patients with stroke who are undergoing inpatient rehabilitation and have some walking function, through the application of augmented therapeutic exercises designed to achieve a normative gait pattern. The evaluation will be conducted using a combination of clinical scales and objective motion sensors that map walking quality and performance during activities of daily living, such as rising from a chair and standing.

It is acknowledged that this single-group pilot study, which aims to include 12 participants, is insufficiently powered to address the primary objective. A larger parallel-design study is required to definitively address this issue. To help design a larger study, the current objectives are: first, to have realistic expectations regarding recruitment and dropout rates; second, to identify potential barriers to therapy adherence and data collection that may impede the success of a larger study; third, assess the test-retest reliability of sensor-based motion capture of movement quality during walking and related tasks in hemiparetic stroke patients. For the latter objective, the sensor measurements at the end of the intervention will be repeated on two consecutive days.

In addition to their usual care, participants will undergo additional therapy over a four-week period, with sessions occurring five times per week for one hour as part of the BOOST GAIT program. The BOOST GAIT sessions will be conducted as group-based therapy with four patients and two physiotherapists present to oversee the performance of mobility-specific exercises, including sit-to-stand transfers, standing and stepping, and eventually walking. The rationale for this approach is that the combined effects of augmenting the amount of therapeutic exercises and specifically targeting motor control of the paretic leg will facilitate symmetry during tasks, which in turn will have carry-over effects on safe performance of walking and other mobility tasks.
