Effectiveness of Lower-Extremity Functional Training (LIFT) in Young Children With Unilateral Spastic Cerebral Palsy: A Randomized Controlled Trial.

Background. Children with unilateral spastic cerebral palsy (USCP) have strength, coordination, and balance deficits affecting gross motor skills, such as walking, running, and jumping. However, there is a paucity of evidence for effective treatments for lower-extremity (LE) function in children with USCP. Objective. To determine the effectiveness of LE intensive functional training (LIFT) compared with an attention control group receiving upper-extremity bimanual training (Hand-Arm Bimanual Intensive Therapy [H-HABIT]). Methods. A total of 24 children with USCP were randomized to receive 90 hours of LIFT (5.8 [2.3] years) or an equivalent dosage of H-HABIT (5.1 [2.6] years) delivered 2 h/d, 5 d/wk for 9 weeks. Caregivers were trained to administer the intervention in the home setting. Progress and skill progression were monitored, and supervision was provided via weekly telerehabilitation. The primary outcome was the 1-minute walk test (1MWT). Secondary outcomes included self-selected and fast walking speeds, ABILOCO-kids, 30-s chair rise test, and single-leg stance. Results. LIFT showed greater improvement for the 1MWT (P = .017) and ABILOCO-kids (P = .008) compared with controls. The other secondary outcomes were not different between groups. Conclusions. The administration of LE intensive interventions in the home setting by caregivers was shown to be an effective and novel mode of delivery for improving gait capacity and performance. LIFT delivered in the home setting using telerehabilitation for monitoring resulted in improvements in ambulation distance and overall walking ability as compared to an intervention of equal intensity and duration that also controlled for the increased social interaction and attention between caregiver and child.
