Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

BACKGROUND: The first metatarsal and medial cuneiform form an important functional unit in the foot called "first ray". The first ray normal function requires that it load part of the body weight in the last period of the stance phase of gait. A dorsiflexed first ray may exist due to abnormal function of the peroneus longus muscle.

OBJECTIVE: To evaluate the improvement in first ray function in tha push-off phase of gait after a 4-week strengthening programme for the peroneus longus.

SUBJECTS: Patients with flexible dorsiflexed first ray. INTERVENTIONS: Patients will be randomly assigned to either group A, which will receive instructions for a strengthening programme of the peroneus longus muscle, or group B, which will receive no treatment.

MAIN MEASURES: The primary outcomes will be mean and maximum plantar pressure under the first metatarsal head.

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Strengthening exercises

The participants in this group will be given instructions to follow a resistance exercises to strengthen the peroneus longs muscle.

Group Type EXPERIMENTAL

Strengthening exercises

Intervention Type OTHER

Participants in group A will be required to complete 12 sessions in 4 to 6 weeks. Resistance-Bands will be used to do ankle plantar flexion and eversion (3 sets of 10 repetitions). Participants will have to be seated on the floor with the knee extended and instructed to perform the movement at the ankle joint without allowing extraneous movement at hip and knee. The resistance band will be doubled and securely attached to the base of a table. The training resistance will be determined by calculating 70% of the resting length of the resistance band and adding this distance to the resting length of the resistance band. Using this calculated distance, the examiner will place a mark to which the resistance band will be stretched during exercise performance on the floor. Each week a study investigator will track each participant's completion. Participants will be instructed to move through their entire range of motion for the direction of each exercise.

Control

Participants in this group will be given no treatment.
