Plantar Stimulation, Whole-Body Vibration, and Baduanjin for Muscle Activation

9 settembre 2026 aggiornato da: Nanfang Hospital, Southern Medical University

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.

Descrizione dettagliata

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.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: 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.

Lasso di tempo
Root Mean Square Value
Lasso di tempo: Day 1: from the resting baseline immediately before each intervention condition through completion of that intervention condition.
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.
Day 1: from the resting baseline immediately before each intervention condition through completion of that intervention condition.
