Features<\/td>In addition to the fatigue caused by standing, the concentration of the weight load on the lower body causes pain in the soles of the feet.<\/td>Sitting on a chair rounds your back and crushes your pelvis, putting a strain on your lower back and causing stiff neck and shoulders.<\/td>When Archelis is worn, the pelvis stands up, the S-shape of the spine is maintained, the trunk is stabilized, and an ideal standing posture is maintained.<\/td><\/tr><\/tbody><\/table><\/figure>\n<\/div><\/div>\n\n\n\n

Distribution of weight<\/span><\/strong><\/h2>\n\n\n\n
\n
\n

When standing unassisted, our weight is concentrated on the soles of our feet, leading to pain or fatigue.<\/p>\n\n\n\n

By distributing weight across the thighs and shins, Archelis can reduce stress on the feet by up to 50%. This can help relieve chronic pain or fatigue caused by prolonged standing.<\/p>\n<\/div>\n\n\n\n

In a study conducted by the Ministry of Health, Labour and Welfare, it was found that the use of Archelis reduced the strain on key muscle groups in the legs and back. The study showed a decrease of up to 41% of activity in the erector spinae and calf gastrocnemius muscles.<\/p>\n<\/div>\n\n\n\n

Additionally, musculoskeletal analysis on a human model showed a reduced load on the lower back by up to 33%. From these studies and simulations it has been shown that Archelis can reduce the strain of standing work.
