Methods | Design: randomised trial of close kinetic chain resistance exercise versus open kinetic chain resistance exercise versus no intervention Randomisation: unclear Allocation concealment: information not included Blinding: information not included ITT: no ITT but no losses Measurements: end of intervention (6 weeks) Withdrawals: none |
|
Participants | Randomised: total 33 participants. 11 to close kinetic chain exercise (CKC), 11 to open kinetic chain exercise (OKC) and 11 to control Intervention 1 (CKC): 11 participants; 7 male, 4 female; mean age: 59.3 (SD 8.87); months after stroke 19.9 (SD 7.59) Intervention 2 (OKC) 11 participants; 7 male, 4 female; mean age 58.8 (SD 6.81); months post‐stroke 20.3 (SD 8.13) Control: 11 participants 6 male 5 female; mean age 60.10 (SD 7.01); months after stroke 19.70 (SD 9.42) Inclusion criteria: age 30 to 65 years; stroke occurring at least 6 months before start of study; sufficient cognition to comprehend study purpose; one‐sided hemiparesis of lower extremity Exclusion criteria: severe cognitive, communicative, perceptual or sensory problems preventing understanding of study purpose; other neurologic or psychiatric problems causing difficulties in following programme; unstable cardiovascular/ventilatory problems |
|
Interventions | Resistance training 5 times/week for 6 weeks Warm up – 4 reps at 25% of 1‐RM followed by 3 sets (8 to 10 reps) at 70% of 1‐RM adjusted weekly Intervention 1 (CKC): – seated, paretic foot on pedal of a leg press machine with pneumatic resistance, extend leg and slowly flex Intervention 2 (OKC) – sat in chair, back facing leg press exercise machine, knee maintained at 90 degrees of flexion with free distal extremity. Extend and slowly flex knee Control: no intervention (maintained routine activity) Setting: unclear |
|
Outcomes | Included outcomes: balance (postural sway) Other outcomes: muscle activation (limb muscle EMG recordings) |
