This training methodology focuses on adjusting the treadmill's speed according to the individual's walking pace, creating a more dynamic and adaptive exercise environment. SDTT is designed to mimic real-world walking conditions and challenges, promoting neuromuscular coordination, balance, and overall mobility. By tailoring the treadmill speed to match the user's gait, SDTT encourages the development of natural and efficient walking patterns. This training technique has shown promise in various clinical settings, aiding individuals with gait impairments caused by neurological conditions, musculoskeletal disorders, or post-injury rehabilitation. Its adaptability allows for progressive adjustments as a person's walking abilities improve, making it a versatile tool for optimizing gait mechanics and functional mobility. To ensure continued progress and integration into daily life, home-based walking training, supported by a phone application, will be included between T1 and T2.

EEG measures brain activity to assess cortical involvement and sensorimotor integration for foot placement control. We'll specifically analyze beta power and beta band corticomuscular coherence with the rectus femoris muscle. Before analysis, EEG data will be cleaned using filtering and ICA to remove artifacts like muscle and eye movements. Coherence will be computed across the gait cycle using time-normalized EEG and EMG cross-spectra, and beamforming will localize sources.

It typically consists of 18 items where participants rate their feelings about physical activity on a 7-point bipolar scale. It has a minimum possible score of 18 (if each item is rated '1') and a maximum possible score of 126 (if each item is rated '7'). Scores from all 18 items are summed to create a total score. Higher scores on the PACES indicate greater enjoyment of physical activity, representing a better outcome. Additionally it includes questions developed specifically for the components of this study.

The Exercise Self-Efficacy Scale (ESES) is designed to assess an individual's confidence in their ability to engage in regular exercise, particularly in challenging situations. There are various versions of self-efficacy scales, but they generally follow a similar structure. It has a minimum possible score of 0 (or the lowest point on the chosen confidence scale) and a maximum possible score of 100 (or the highest point on the chosen confidence scale). Participants typically rate their confidence for various exercise-related scenarios on a percentage scale, for instance, 0% = not at all confident to 100% = completely confident. The scores are then averaged or summed. Higher scores on the Exercise Self-Efficacy Scale indicate greater confidence in one's ability to exercise, representing a better outcome.
