Muscle strength measurements with the handheld dynamometer are sometimes performed according to manual muscle testing. However, measuring hip extensor muscle strength in the prone position is difficult, since the some older adults have kyphosis or flexion contracture of the lower limbs. Alternatively, there is the standing position method of manual muscle testing, which accomodates those malalignments; however, it is known that the muscle strength of the lower limb that is not measured affects the measurement result. Hence, we devised the hip extensor strength measurement in a sitting position for healthy males in previous studies. This study examined the reliability and validity of the sitting measurement by a handheld dynamometer in older adults.
