Study Arms (2)

Combined training group

EXPERIMENTAL

Biomechanical taping will first being applied to the participants of the combined training group. They will be asked to perform following exercises in this session afterwards. As the treatment session goes on, a set of foot intrinsic muscle strengthening exercise and lower extremity neuromuscular exercise will be provided.

Other: combined training

Proximal training group

ACTIVE COMPARATOR

For participants of the proximal training group, only a set of lower extremity neuromuscular exercise will be provided. This set of exercises is designed to be the same as for participants of combined training group.

Other: Proximal training

Interventions

combined training OTHER

The whole intervention period will last for 6 weeks, 2 visits per week, 1 hour per visit in the Research Building Room 630 of National Yang Ming University. All programs will be under the supervision of a physiotherapist with 2-year experience individually. 1. Hallux valgus correction: 1.1 Joint alignment correction (Grade II joint mobilization, 10 times/set, 3 sets/visit) - 1st MTP joint distraction - Proximal talofibular joint anteroposterior glide - (Grade III joint mobilization if any restriction being found) 1.2 Biomechanical taping (using Dynamic taping, 1 time/ visit, keep the taping for 2 days minimum) 1.3 Foot intrinsic muscle strengthening (10 times/set for each exercise, 3 sets/visit): - Short foot exercise - Toespread out exercise - Heel-rise exercises 2. Lower extremity neuromuscular exercises: (10-15 times/set, 3 sets/visit) 2.1 Single lunge 2.2 Stepping down 2.3 Vertical squat 2.4 Vertical jumping

Also known as: hallux valgus correction, lower extremity neuromuscular exercises

Combined training group

Proximal training OTHER

1\. Lower extremity neuromuscular exercises: (10-15 times/set, 3 sets/visit) 1.1 Single lunge 1.2 Stepping down 1.3 Vertical squat 1.4 Vertical jumping All exercises will first start on firm surface without additional resistance/weight. Later, settings will be gradually shifted into on firm surface with resisted band from random direction, on a cushion with/ without resisted band, on a BOSU balance trainer. Progression are made every 2 weeks ideally, while adjustments may be taken into concern due to individual differences.

Also known as: lower extremity neuromuscular exercises

Proximal training group
