Positive effects of lower extremity constraint-induced movement therapy on balance, leg strength and dual-task ability in stroke patients: a longitudinal cohort study

Objective: To investigate whether high-intensity lower extremity constraint-induced movement therapy can improve balance, leg strength, and dual-task ability. Design: A longitudinal cohort study in a real-world outpatient clinic. Patients: 147 community-dwelling participants in the subacute and chronic poststroke phases. Methods: Participants received lower extremity constraint-induced movement therapy for 6 hours/day during 2 consecutive weeks, including balance, strength, and functional training. The Berg Balance Scale (BBS), Single-Leg-Stance (SLS) bilaterally, one Repetition Maximum (1RM) in a leg press, symmetry of leg strength (Diff-1RM), Timed Up and Go (TUG), and the TUG Manual test were assessed before, after, and 3 months after lower extremity constraint-induced movement therapy. Results: Compared with preintervention data, statistically significant improvements after lower extremity constraint-induced movement therapy (p
