高齢者におけるフットタッピング動作による足底屈および足背屈最大筋力の簡易推定法の提案

抄録

  The purpose of this study was to propose the simple estimative method for clarifying the relationship between the maximum strength and the number of foot-tapping during 15sec on planter-flexion and dorsi-flexion. The subjects were 80 elderly persons who were in stable health condition. The originally designed equipment was used for this study, and it measured the maximum strength on planter-flexion and dorsi-flexion. At this measurement, the posture was set the back position, because it was not affected from the hip extension and knee extension. The number of foot-tapping movement during 15sec was counted by a light-sensor of the originally equipment. The posture at the foot-tapping test was the sitting position (knee joint was 90 degree and ankle joint was 90 degree). In results, there was significant relationship between the number of planter-flexion foot-tapping movement and measurement of the strength on planter-flexion. On the other hand, there was no-significant relationship between the number of dorsi-flexion foot-tapping and measurement of the maximum strength on dorsi-flexion. In conclusion, these results suggest that the maximum number of planter-flexion foot-tapping could estimate the maximum strength on planter-flexion in the elderly.
