Study of the Discomfort Resulting from Leg Swelling during Prolonged Standing and Walking Seiji SAITO, Satoshi MURAKI Faculty of Computer Science and Systems Engineering, Okayama Prefectural University, Faculty of Design, Kyushu University Abstract : The purpose of this study was to investigate the leg discomfort related to swelling of the leg during prolonged standing and walking. Ten male subjects were asked to stand upright for 0 min and walk at.8 km/h for 0 min (rest: work ratio, 0:0). To evaluate swelling, the discomfort in the thigh, lower leg, and foot were assessed every 5 min, and the circumference and muscle hardness of the thigh and lower leg, impedance value of the lower leg, ground contact area of foot, and height of the first cuneiform bone were evaluated every 0 min. Leg discomfort gradually increased in both standing and walking sessions and was larger at the lower leg and foot compared to the thigh. During the standing session, subjects complained of undesirable sensations, such as lower-leg fatigue, foot strain, pain, and pressure, more frequently and sooner than they did during walking. Circumference of the thigh and lower leg increased over time in the standing position but did not change during walking. The impedance of the lower leg decreased over time during standing but gradually increased during walking. These observations suggest that the discomfort and related symptoms associated with swelling of the leg, including fatigue, strain, pain, and pressure sensations, appear to be prominently related to the lower leg posture during standing. Prolonged walking, compared to standing, appears to attenuate symptoms associated with the occurrence of leg discomfort related to leg swelling.
