The purpose of the study was to examine the effect of resistance training on joint flexibility and muscle strength of upper extremities of institutionalized elderly with impaired cognition. The study design was pretest-posttest control group study and inclusion criteria were elderly aged 65-year older, MMSE score 23 or less, ones who had no serious physical and/or mental problem except impaired cognition, and were capable to carry out resistance training. After consents were obtained participants were randomly assigned. Pre-post evaluation was performed by staff nurses trained beforehand. Among those 4-week study period, experiment was carried out during 5 consecutive days a week for 3 weeks. ROM and extension range of shoulder joints and muscle strength of shoulders and hands for both sides were measured. Flexion, extension, abduction range of right shoulder joint was significantly improved. Flexion and extension muscle strength of left side shoulder and abduction muscle strength of both sides of shoulder were significantly improved. With the study result, it could be concluded that resistance training has therapeutic effects on joint flexibility and muscle strength. More studies adopted longer experimental period to evaluate timing of effect and extinction to refine the protocol are called for.
