Plantar Stimulation, Whole-Body Vibration, and Baduanjin for Muscle Activation
Study on the Activation Effect of Vibration Training Under Plantar Stimulation and Baduanjin on Lower Limb Muscles
This study will examine how different short-term exercise and vibration conditions affect lower-limb muscle activity in young adults with flat feet and young adults with normal feet.
Participants will complete several conditions, including whole-body vibration, whole-body vibration combined with plantar stimulation under different areas of the foot, and a Baduanjin heel-raise exercise. Surface electromyography sensors will be placed on the skin over selected lower-limb muscles to record muscle activity before and during each condition. Each participant will complete all study conditions in a balanced order.
This study does not aim to treat flat feet or evaluate long-term clinical benefits. The purpose is to collect preliminary information on immediate muscle activation and foot discomfort, which may help design future studies on foot-related exercise, plantar stimulation, and rehabilitation training.

상세 설명
This is a prospective, exploratory, self-controlled crossover study designed to investigate the immediate effects of different exercise and vibration-based conditions on lower-limb muscle activation.
Flat feet may be associated not only with structural changes of the foot arch, but also with altered neuromuscular control of the lower limb. Whole-body vibration provides a standardized mechanical stimulus, while Baduanjin heel-raise exercise represents an active movement-based training condition. Because the plantar surface is an important sensory input area, this study will also examine whether adding regional plantar stimulation to whole-body vibration produces different muscle activation patterns compared with whole-body vibration alone.
Participants will be classified as having flat feet or normal feet based on foot type assessment. Each participant will complete all study conditions in a balanced order, including whole-body vibration alone, whole-body vibration combined with stimulation of different plantar regions, and Baduanjin heel-raise exercise. Surface electromyography will be used to record lower-limb muscle activity before and during each condition.
This study is not designed to evaluate treatment efficacy or long-term clinical outcomes. Its purpose is to collect preliminary mechanistic data on immediate neuromuscular responses, which may inform future studies on plantar stimulation, vibration training, and individualized rehabilitation strategies.

실험적: Flatfoot Group
Participants will complete three types of study conditions. In the whole-body vibration (WBV) condition, they will stand barefoot at the center of the vibration platform with feet about 20 cm apart, knees flexed at 20°-25°, arms relaxed, head and neck neutral, eyes forward, and body weight evenly distributed. WBV will be delivered at 20 Hz and 2 mm for 60 seconds. For WBV plus regional plantar stimulation, the same posture and WBV parameters will be used. A plantar stimulation module will be placed on the platform, and participants will position the assigned plantar region on the module. Four regions will be stimulated separately: toe region, metatarsal head region, medial plantar/tibial-side region, and lateral plantar/fibular-side region. Each condition will last 60 seconds. For the Baduanjin condition, participants will perform the "Bei Hou Qi Dian Bai Bing Xiao" heel-raise movement under professional guidance, with 6 repetitions completed within 60 seconds. |

Root Mean Square Value

Electrodes were placed per SENIAM standards (2000 Hz sampling, 20-450 Hz band-pass and 50 Hz band-stop filtering).
Data were collected during a 30 s resting baseline and the 30-60 s stable phase of intervention.
After offline full-wave rectification, RMS was calculated using a 200 ms sliding window (100 ms step).
Mean RMS within each epoch was adopted as the representative value.
