This study examines the efficacy of a gait trainer with body-weight support (BWS) in patients post-stroke. The top graph depicts effective body-weight support recorded over 10 strides for a representative 66-year-old patient with a functional ambulation category score of 0. The bottom graphs illustrate acceleration in craniocaudal, laterolateral, and anteroposterior directions during the session, which utilized a static body-weight support of 30 kg, walking speed of 0.5 m/s, and step length of 0.4 m. The findings highlight the impact of gait training on both paretic and nonparetic limb performance.

Figure 4. Top graph shows effective body-weight support (BWSe) recorded during 10 strides for representative patient (age = 66 years, body mass = 78 kg, Functional Ambulation Category score = 0). Bottom graphs show relevant acceleration (a) in craniocaudal (aCC), laterolateral (aLL), and anteroposterior (aAP) directions. Gait Trainer parameters during this session were body-weight support in static posture (BWSs) = 30 kg, effective walking speed = 0.5 m/s, and step length = 0.4. Dark and light gray bands represent steps of paretic and nonparetic limbs, respectively. Iosa M, Morone G, Bragoni M, De Angelis D, Venturiero V, Coiro P, Pratesi L, Paolucci S.
