Analysis of Surface Muscle Activity of Lower and Upper Musculus Erector Spinae According to Walkers form

Abstract

The aims of this study are to analysis about surface muscle activity of lower and upper musculus erector spinae according to walkers form. The subjects of the current step is inconvenient to use a walker and five people over the age of 65 valid samples were selected as final. All the subjects were measured in three forms. Wireless EMG muscle activity is a measure of surface measurements were measured using a system, both musculus vastus lateralis, outside the erector spinae muscle, musculus biceps femoris, gastrocnemius muscle was attached to the channel electrodes. According to the results, First, gastrocnemius muscle activity showed significant differences by type of gait. Second, the muscle activity of the erector spinae muscle walking showed significant differences by type, side grip type showed the lowest muscle activity. Consequently, the present study is the efficient use of the four-wheel walker will provide the baseline data.

An analysis of the negative asymmetry in the coronal body shape of the old people in South Korea

“…The stretched posture of Koreans can cause a pelvic list, resulting in scoliosis. The muscle atrophy and the walking posture of older people leads to coronal asymmetry in their body shape [9], and this trend of asymmetry increases with age.…”
