Pelvic-Restricted vs. Pelvic-Free Robot-Assisted Gait Training in Stroke Patients

Starting soon · Not applicable

Conditions studied: Stroke, Hemiplegia, Gait Disorder, Sensorimotor, Balance Impairment, Fear of Falling

In brief

This randomized controlled clinical trial aims to compare the effects of pelvic-free versus pelvic-restricted robot-assisted gait training (RAGT) on gait pattern, balance, and fear of falling in stroke patients. Stroke survivors often experience gait impairments, reduced balance, and fear of falling, which limit independence and quality of life. Conventional physiotherapy requires high intensity and repetition but is restricted by therapist capacity. Robotic gait systems provide intensive, repetitive, and safe training; however, most limit pelvic motion, potentially disrupting natural gait patterns and balance strategies. A total of 36 participants with chronic stroke (≥6 months post-stroke, age ≥18 years, hemiplegic gait disorder, Functional Ambulation Category ≥2) will be randomized into two groups: (1) pelvic-free RAGT plus conventional rehabilitation, or (2) pelvic-restricted RAGT plus conventional rehabilitation. Interventions will consist of 8 RAGT sessions (twice weekly) and 20 conventional rehabilitation sessions (five times weekly) over 4 weeks. Primary outcomes include gait analysis parameters (gait speed, step length, cadence, temporal symmetry index) and clinical measures such as the Berg Balance Scale, Functional Ambulation Category, Motricity Index (lower limb), and Falls Efficacy Scale-International. Assessments will be performed at baseline and after 4 weeks of treatment. The study hypothesizes that pelvic-free RAGT will improve gait symmetry, balance, and reduce fear of falling more effectively than pelvic-restricted training. Results are expected to provide evidence supporting the integration of pelvic-free robotic gait systems into post-stroke rehabilitation to enhance functional recovery and patient confidence
