The sit to stand (STS) analysis and particularly the 5-repetition sit-to-stand test (FRSTST) introduced by Bohannon [1] are widely used measurements of functional strength and disability level of young and elderly subjects. For example in rehabilitation and orthopedics,

• children with cerebral palsy, for which the FRSTST was found a reliable and valid test to measure functional muscle strength in children with spastic diplegia in clinics [2, 3]; • older adults, for which the FRSTST test-retest reliability can be interpreted as good to high

• subjects with rheumatoid arthritis [9] or alterations in advanced knee osteoarthritis [10];

• STS and gait support system for elderly and disabled [13], and also handrail positions and
