Both group will record his/her baseline activity level with a given pedometer. After one week recording, we started initial evaluation (history taking, physical examination) and intervention.~Participants are taught thera-band resisted exercise, including large musculature of upper and lower extremities, each exercise are conducted 10-15 times for 3 sets.~Traditional group will receive an education leaflet and a notebook to record his/ her daily activity and frequency of exercise to record the compliance.~Video-assisted group will receive a QR code, which contain a website of exercise video on the cloud.~After 3 months intervention, participant will come back to our center for final examination.
This research aims to identify whether the effects of video-assisted physical therapy, including home resistance training, is superior to traditional physical therapy, education leaflet for example.~This is an interventional research, single-blind, randomized control trail. We recruit high risk of sarcopenia people (low muscle strength and low physical performance) Two groups of participants are divided into traditional group and video-assisted group, both group are taught the same resisted exercise by physical therapist.
