AIM: To investigate the effects of a 12-week split-belt treadmill walking (Sb-TW) practice using an error augmentation strategy on temporospatial gait asymmetries, dynamic balance, and locomotor capacity in adolescents with unilateral cerebral palsy (ULCP).
METHODS: Fifty-two adolescents with ULCP (age: 10-16 years) were randomized into either the Sb-TW group ( = 26; underwent repeated Sb-TW practice, with exaggeration of the initial step-length asymmetry, three times/week, for 12 sequential weeks) or control group ( = 26; received equivalent dosages of traditional single-belt treadmill training). Step-length and swing-time asymmetries, directional (LoS) and overall (LoS) limits of stability, and locomotor capacity [6-minute walk test (6-MWT), Timed Up and Down Stair test (TUDS), and 10-m Shuttle Run Test (10mSRT)] were assessed pre- and post-intervention.
RESULTS: The Sb-TW group demonstrated more favorable changes in step-length asymmetry ( < .001, = 0.27), LoS [affected side direction ( = .033, = 0.09), forward direction ( = .004, = 0.16), and backward direction ( = .01, = 0.12)], and LoS ( < .001, = 0.31) than the control group. Also, the Sb-TW group showed significantly higher locomotor capacity [6-MWT ( < .001, = 0.38), TUDS ( = .032, = 0.09), 10mSRT ( = .021, = 0.10)] as compared to the control group.
CONCLUSION: The Sb-TW-induced adaptations can be capitalized on for remediating spatial gait asymmetry, dynamic balance deficits, and impaired locomotor performance in adolescents with ULCP.
