Study of simple and easy method for elbow joint torque measurement using Hand-held sensor

Elbow isometric flexion joint torque (EF) and elbow isometric extension joint torque (EE) were measured with the hand-held dynamometer (HHD) in 24 normal healthy men and women aged 20s decade to 50s decade, to test the validity of EF and EE measured with HHD comparing with the torque measurement machine (TM), in order to prepare the measurement of upper and lower limb ʼ s isometric joint torque with about 1,000 subjects across the age, with the examiners who were not medical specialists. As a result, intra-session variation of HHD measurements were fare (coefficient of variation ranged from 0.01 to 0.08), and there were not significant differences in inter-session variation and also in inter-tester variation (correlation coefficients ranged from 0.915 to 0.959). In comparison with HHD measurements and TM measurements, they did not differ significantly and validity of HHD measurements were fair (correlation coefficients ranged from 0.813 to 0.950).
