Study Arms:
- Error reduction (Type: EXPERIMENTAL): Participants will complete a 12-week training program, in which they practice walking on a treadmill for 30-minutes during twice-weekly training sessions. During these sessions, participants will interface with a custom-built force-field able to exert mediolateral forces on the legs, which will be in error reduction mode. This training period will be followed by a 12-week follow-up period. Five assessment sessions will be interspersed throughout this total 24-week period.
- Error augmentation (Type: EXPERIMENTAL): Participants will complete a 12-week training program, in which they practice walking on a treadmill for 30-minutes during twice-weekly training sessions. During these sessions, participants will interface with a custom-built force-field able to exert mediolateral forces on the legs, which will be in error augmentation mode. This training period will be followed by a 12-week follow-up period. Five assessment sessions will be interspersed throughout this total 24-week period.
- Activity matched control (Type: SHAM_COMPARATOR): Participants will complete a 12-week training program, in which they practice walking on a treadmill for 30-minutes during twice-weekly training sessions. During these sessions, participants will interface with a custom-built force-field able to exert mediolateral forces on the legs, which will be in transparent mode. This training period will be followed by a 12-week follow-up period. Five assessment sessions will be interspersed throughout this total 24-week period.

Based on this trial design, predict the completion outcome and termination type (if applicable).
