Resistance training in stroke rehabilitation: systematic review and meta-analysis.

Strength training is a familiar tool in general rehabilitation, but its place in stroke recovery has been less settled, since weakness after stroke often coexists with spasticity and balance problems that some clinicians worry resistance work might aggravate. This review pooled 30 randomized trials involving just over a thousand stroke patients to compare resistance training against no intervention, against other therapies, and against different resistance protocols, across outcomes like gait, strength, balance, quality of life, spasticity and cardiorespiratory fitness. The broad picture was encouraging for several outcomes: resistance training outperformed other therapies for muscular strength and motor function, quality of life, independence and reintegration, and some physiological measures, while showing no statistically significant difference from other therapies for walking ability, balance and spasticity. It was less effective than ergometer training specifically for cardiorespiratory fitness.

Training details mattered too, with leg press outperforming knee extension and higher intensity outperforming lower intensity. The authors themselves caution that despite these promising patterns, the evidence base remains too limited to firmly guide rehabilitation practice.

If you or someone you know is recovering from a stroke, you may wonder whether strength training, not just walking or balance practice, has a place in rehab. This review looked at 30 studies involving just over a thousand stroke patients to see how resistance training compared with doing nothing, with other types of therapy, and with different ways of doing resistance training itself. Overall, resistance training seemed to help with several important things, including muscle strength, motor function, quality of life, and independence in daily life, showing an advantage over other therapies in these areas.

For walking, balance, and muscle stiffness, it worked about as well as other therapies but not clearly better. For improving heart and lung fitness specifically, training on an exercise bike appeared to work better than resistance exercises.

The way training was done also seemed to matter, with certain exercises and higher effort levels showing more benefit than others. The researchers are clear that even though these patterns look encouraging, the overall evidence is not yet strong enough to say definitively how resistance training should be used in stroke recovery.

This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.

This meta-analysis pooled 30 randomized controlled trials (n=1051) comparing resistance training against no intervention, against alternative interventions, and across differing resistance protocols in stroke rehabilitation, evaluating eight outcome domains including gait, strength/motor function, balance, quality of life, spasticity, cardiorespiratory fitness, cognition and other physiological indicators. Results indicated resistance training was superior to other therapies for muscular force and motor function of upper and lower limbs, health-related quality of life, independence and reintegration, and select physiological indicators. No statistically significant difference was detected versus other therapies for walking ability, mobility/balance/postural control, or spasticity and hypertonia.

Resistance training was inferior to ergometer training specifically for cardiorespiratory fitness. Protocol characteristics influenced outcomes, with leg press more efficient than knee extension and high-intensity training superior to low-intensity training. Despite the reasonably large pooled sample across 30 trials, the authors explicitly state the current evidence is insufficient for evidence-based rehabilitation, implying meaningful heterogeneity in trial design, populations, and protocols that limits firm clinical conclusions.

Clinicians should interpret these comparative findings as hypothesis-generating patterns from synthesized trial data rather than settled, high-certainty guidance, given the acknowledged limitations in the underlying evidence base.
