Manual muscle strength testing device

Abstract

The purpose of the present invention is: to providing a manual muscle strength testing device with which it is possible, by using an inertial sensor and a load exercise measurement device of simple configuration, to capture very small muscle contractions of the fingers while suppressing the compensatory effects of surrounding muscles; and to make it possible to evaluate the state or the degree of recovery of the median, ulnar, and radial nerves by measuring only a load exercise of the index finger. A manual muscle strength testing device according to the present invention has, inter alia: a finger insertion portion 30, comprising an other finger fixation portion 28 having a space that is shaped so as to prevent movement, in any direction, of a middle, a ring, or little finger inserted thereinto, and an index finger insertion portion 29 having a space that is shaped such that an inserted index finger is able to move towards the ventral side or the thumb side, or the nail side or the thumb side; a ring 15 that can be fitted onto the fingertip of the index finger; a pressure sensor 32 capable of measuring the magnitude of a load applied on the fingertip and a 3-axis acceleration sensor 11 capable of measuring the movement of the fingertip, fixed to the ring 15; and a load elastic body 31 that applies an adjustable load to the fingertip on which the ring 15 is worn.
