| Outline of Final Research Achievements |
In a cycle of treadmill walking, the displacement range and speed of skin around the knee joint were about 3 mm / 10 mm and 10 mm / s. Therefore, we investigated postural responses to skin stretch stimuli, applying these values as stimulation intensity. For the stimulation to various positions around the knee, postural response was most frequently observed at the myotendinous junction of the rectus femoris (RF), and the ratio of forward leaning response to backward was six to four. For the stimulation at this position with various pressure, forward and backward leaning responses were mainly induced with lower and higher pressure than 25 g, respectively. For the simultaneous stimulation to the front and back of the hip, knee or ankle, clear postural response was observed in any joint. The simultaneous stimulation to the front of the knee and ankle induced forward leaning response more clearly.
