May 27, 2026 updated by: George Hornby, Indiana University

Feasibility and Potential Efficacy of High-intensity Gait Training in Individuals With Cerebellar Damage

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

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: High-intensity training in variable contexts
High-intensity training focused on stepping tasks in variable contexts (tasks and environments) while targeting higher cardiovascular intensity (>75% maximum predicted heart rates) during up to 40 mins of 1-hr sessions. A total of 20 sessions will be targeted.
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 the treadmill speed and incline as well as addition of weights to the torso or limbs for the purpose of error augmentation and not to dampen ataxia. Sessions will focus on achieving up to 40 minutes of stepping training within each 60-minute session. Potential tasks include walking in multiple directions, over inclines and obstacles, and/or with weighted vests and leg weights with limited handrail use as tolerated and decided by the therapist and participant.
Other Names:
  • Locomotor training at higher intensities
Active Comparator: Conventional balance training
Conventional balance activities will consist of sitting and standing balance exercises, with selected dynamic stability exercises performed during walking tasks. Heart rates will be monitored with no targeted range. All sessions will be 1-hr long with balance activities for up to 40 minutes per session. A total of 20 sessions will be targeted.
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 activities in the sitting position, ~20 minutes (50% of sessions) of standing positions and ~10 minutes (25% of sessions) of walking training.
Other Names:
  • Static and dynamic stability training
