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

Abstract

Objective: This systematic review and meta-analysis investigates the effects of resistance training in supporting the recovery in stroke patients. Data sources: PubMed, the Cochrane Central Register of Controlled Trials and the PEDro databases were reviewed up to 30 April 2020. Review methods: Randomized controlled trials were included, who compared: (i) resistance training with no intervention, (ii) resistance training with other interventions and (iii) different resistance training protocols in stroke rehabilitation. Results: Overall 30 trials ( n = 1051) were enrolled. The parameters evaluated were: (1) gait, (2) muscular force and motor function, (3) mobility, balance and postural control, (4) health related quality of life, independence and reintegration, (5) spasticity and hypertonia, (6) cardiorespiratory fitness, (7) cognitive abilities and emotional state and (8) other health-relevant physiological indicators. The data indicates that: (i) resistance training is beneficial for the majority of parameters observed, (ii) resistance training is superior to other therapies on muscular force and motor function of lower and upper limbs, health related quality of life, independence and reintegration and other health-relevant physiological indicators, not significantly different from other therapies on walking ability, mobility balance and postural control and spasticity and hypertonia, and inferior to ergometer training on cardiorespiratory fitness and (iii) the type of resistance training protocol significantly impacts its effect; leg press is more efficient than knee extension and high intensity training is superior than low intensity training. Conclusion: Current data indicates that resistance training may be beneficial in supporting the recovery of stroke patients. However, the current evidence is insufficient for evidence-based rehabilitation.
