N2 - Walking is a routine activity and is performed by exerting the lower limb muscles. The abnormality of lower limb muscle activity influenced by the use of footwear will cause injury to the neuro-musculoskeletal system. This study attempts to analyze changes in the lower limb muscle activity pattern during walking when using three different types of shoe soles flexibility. Walking under barefoot conditions will be the control variable in this study. Based on Electromyography and Ground Reaction Force signals, 30 healthy participants with an age range of 30.93±7, weight of 64.41±10, and height of 166.6±6 were participating in this study. The analyzed muscle activity was Gastrocnemius Medial (GM), Tibialis Anterior (TA), and Vastus Medial (VM) when walking under four conditions (Barefoot, using flexible, Mid-flexible flexible, and hard soles). Electromyography and GRF signals will be analyzed using time domain analysis. We hypothesized that walking in three different flexures can change the pattern of muscle activity in the parameters of peak amplitude, duration of muscle activity, and peak amplitude position when compared to the control variables. The plantar pressure during walking also changes compared to the control variable. We found that in flexible shoes, the parameters of peak amplitude in the GM and VM muscles showed the closest pattern to the control variable, that is barefoot. Similar conditions happen on peak amplitude position parameters in the GM and TA muscles, while in the duration of muscle activity parameter, all three muscles of flexible shoes showed the closest pattern to the barefoot condition. When referring to the GRF, pressure patterns close to barefoot conditions were found in the flexible shoes, followed by mid-flexible shoes and hard shoes. However, when analyzing the peak position of GRF during walking different patterns happen. Changes in muscle activity patterns during walking when wearing three different conditions of shoe soles can be a consideration when choosing shoes that will be used daily to reduce the adverse effects in the future.
