Blood flow restriction during walking training in bilateral cerebral palsy (EMBRIN): a pilot feasibility study protocol

Year: 2026

Type: article

Abstract: INTRODUCTION: Children with bilateral cerebral palsy (BCP) frequently develop progressive gait impairments driven in part by muscle weakness. Although power training, which involves high-velocity loaded movements, can enhance functional capacity, its substantial physical demands often limit feasibility in this population. Blood flow restriction (BFR) training has emerged as a promising alternative, capable of eliciting comparable physiological benefits while using low-intensity exercise. This study evaluates the feasibility, safety and clinical effects of integrating BFR with treadmill training in children with BCP, an innovative approach that may deliver the advantages of intensive strengthening while reducing physical burden. METHODS AND ANALYSIS: This single-centre pilot study uses a double-baseline design with 13 participants with BCP (Gross Motor Function Classification System II-III), aged 8-18. The protocol consists of a 10-week usual care period followed by a 10-week Blood Flow Restriction Treadmill Training (BFR-TT) intervention, with three sessions per week. Feasibility targets were defined as completion of at least 80% of at least 80% of sessions. Safety is monitored through pain scales and adverse events. Outcomes assess body function (strength, GAITRite), activity (walking speed, walking endurance and motor function) and participation (daily activities), comparing changes between the usual care and BFR-TT periods. ETHICS AND DISSEMINATION: This study was approved by the French Protection of Persons Committee (2024-A00791-46). Results will be published in peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBER: NCT06533956.
