Official title
Feasibility and Potential Efficacy of High-intensity Gait Training in Individuals With Cerebellar Damage
Overview
The goal of this study is to evaluate the feasibility and potential preliminary efficiency of high-intensity training focused on stepping in variable contexts as compared to conventional training in individuals with cerebellar disease
Detailed description
The goal of this study is to evaluate the feasibility and potential preliminary efficiency of high-intensity training focused on stepping in variable contexts as compared to conventional training in individuals with cerebellar disease
Interventions
- Other High-intensity training in variable contexts
High intensity stepping training: Training sessions will focus on maximizing stepping activities in variable contexts while targeting ≥70% HR reserve (or approximately 80% age-predicted maximum HR) calculated using the Karvonen formula. Target HR will be decreased by 10 beats if the individual is on beta-blockers. Intensity will also be monitored using the Borg RPE scale every 3-5 minutes with goals of ≥15 on a 6-20 scale. The intensity of the walking training will be primarily modulated through - Other Conventional balance training
Conventional training: Training sessions will focus on improving static and dynamic balance, while calculated using the Karvonen formula. Target HR ranges will be decreased by 10 beats if the individual is on beta-blockers. Intensity will also be monitored using heart rates and RPE every 3-5 minutes with goals of \<14 on a 6-20 scale. Sessions will focus on balance training for up to 40 minutes within a 60-minute session. Individuals will perform \~10 minutes (\~25% of sessions) on balance activ
Primary outcome measures
- 6-min walk test [Time frame: Changes from baseline to post-training following up to 20 sessions over approximately 8 weeks]
