Abstract
Background: Blood flow restriction creates a state with increased motor function that permits treatment modalities to induce muscle hypertrophy. Blood flow-restricted exercise training (BFRET) may induce motor learning and boost the facilitatory effect of exercise training (ET).
Objective: This study investigated the effects of BFRET on post-stroke hemi paretic lower extremity function and walking capacity recovery.
Methodology: This randomized clinical trial was conducted from September 2021 to October 2022 at the Department of Rehabilitation Medicine of the Second Affiliated Hospital of Chongqing Medical University in China. Participants were randomized 1:1 to BFRET or ET, each involving 30 minutes of training twice per day for 4 weeks.
Main outcomes measures: The main outcomes were manual muscle testing (MMT) and Fugl-Meyer assessment scale-lower extremity (FMA-LE), the timed up and go test (TUGT), Outcomes were assessed by blinded raters after 4 weeks of training.
Results: 40 participants mean [SD] age 48.79[12.58] years, 30 males [75%], 20 were randomized to BFRET and 20 to ET. The mean (SD) time since stroke was 2.5 (1.3) years. The MMT scores showed greater strength by within-group comparisons and superior changes in hip flexion and plantar flexion in the BFRET group.
Conclusions: BFRET is superior to ET alone in enhancing muscle mass and strength in the lower extremities. BFRET may improve the function of the lower extremities through physiological adaptations for muscle hypertrophy.
期刊介绍:
Topics in Stroke Rehabilitation is the leading journal devoted to the study and dissemination of interdisciplinary, evidence-based, clinical information related to stroke rehabilitation. The journal’s scope covers physical medicine and rehabilitation, neurology, neurorehabilitation, neural engineering and therapeutics, neuropsychology and cognition, optimization of the rehabilitation system, robotics and biomechanics, pain management, nursing, physical therapy, cardiopulmonary fitness, mobility, occupational therapy, speech pathology and communication. There is a particular focus on stroke recovery, improving rehabilitation outcomes, quality of life, activities of daily living, motor control, family and care givers, and community issues.
The journal reviews and reports clinical practices, clinical trials, state-of-the-art concepts, and new developments in stroke research and patient care. Both primary research papers, reviews of existing literature, and invited editorials, are included. Sharply-focused, single-issue topics, and the latest in clinical research, provide in-depth knowledge.
