Brief Summary

This randomized, single-blind clinical trial investigates whether adding whole-body vibration (WBV) to a supervised foot core exercise program improves ankle muscle strength, balance, and proprioception in overweight and obese young adults (BMI 25.0-39.9 kg/m²). Participants attended 24 face-to-face sessions over 8 weeks (3×/week) under physiotherapist supervision. Outcomes included isometric inversion/eversion strength (hand-held dynamometry) and instrumented balance/proprioception tests (Limits of Stability, mCTSIB, single-leg balance, single-leg proprioception) recorded by a computerized balance analysis system.

Foot Core; Balance; Proprioseption; Whole Body Vibration

Outcome Measures

Primary Outcomes (1)

• Limits of Stability (composite score, %)

  Composite score from PROKIN computerized balance analysis system; higher scores reflect better voluntary control within stability boundaries; device-generated percentage scale. Safety Issue: No.

  Baseline to Week 8

Secondary Outcomes (4)

• Single-Leg Balance test (device score)

  Baseline to Week 8

• Modified Clinical Test of Sensory Interaction on Balance (mCTSIB)

  Baseline to Week 8

• Ankle Strength (kg-force)

  Baseline to Week 8

• Single-Leg Proprioception

  Baseline to Week 8

Study Arms (2)

Exercise Group (EG)

ACTIVE COMPARATOR

Progressive foot core exercise program performed on a vibration platform with vibration disabled; supervised 3×/week for 8 weeks (24 sessions). Standardized warm-up/self-massage, then sequence including foot tapping, bilateral heel raises, arch raises with toe ab/adduction, and single-leg stance on BOSU; progression by repetitions and active time.

Behavioral: Supervised Foot Core Exercise Training (No Vibration); Device: Whole-Body Vibration via DKN Technology Xg-10 Pro

WBV-Combined Exercise Group (TEG)

EXPERIMENTAL

Identical supervised foot core exercise program performed with whole-body vibration during exercises; same schedule (3×/week, 8 weeks).

Device: Whole-Body Vibration via DKN Technology Xg-10 Pro

Interventions

Supervised Foot Core Exercise Training (No Vibration) BEHAVIORAL

24 face-to-face sessions over 8 weeks; physiotherapist-led progression in repetitions/active time; performed on DKN Xg-10 Pro with vibration off.

Exercise Group (EG)

Whole-Body Vibration via DKN Technology Xg-10 Pro DEVICE

Tri-directional vibration delivered during exercises at 20-50 Hz with 15-60 s stimulus durations per set, progressing across sessions; administered concurrently with the foot core tasks under physiotherapist supervision (total 24 sessions).

Exercise Group (EG); WBV-Combined Exercise Group (TEG)
