NCT03423498

Brief Summary

The effectiveness of conservative treatment of hallux valgus deformity has not been sufficiently explored yet. The aim of this study was to assess the effect of the toe-spread-out exercise on the amplitude and frequency pattern in a surface electromyographic examination in patients with hallux valgus and in people without the deformity. An additional objective is the assessment of nerve conduction in an electroneurography and the assessment of range of motion in a clinical examination.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of changes in amplitude of motor unit action potential (MUAP)

    The amplitude of motor unit action potential (MUAP) recorded from the abductor hallucis muscle in three phases of exercise and measured in mV

    2 weeks (14 days)

Secondary Outcomes (1)

  • Evaluation of changes in frequency pattern of abductor hallucis muscle activity

    2 weeks (14 days)

Other Outcomes (3)

  • Evaluation of changes in amplitude of the CMAP (compound muscle action potential) from the tibial nerve and of the SNAP (sensory nerve action potential) from the sural nerve

    2 weeks (14 days)

  • Evaluation of changes in latency of the CMAP (compound muscle action potential) from the tibial nerve and of the SNAP (sensory nerve action potential) from the sural nerve

    2 weeks (14 days)

  • Evaluation of changes in conduction velocity of the CMAP (compound muscle action potential) from the tibial nerve and of the SNAP (sensory nerve action potential) from the sural nerve

    Time frame: 2 weeks (14 days)

Study Arms (2)

groups with toe-spread-out exercise

EXPERIMENTAL

This arm included individuals with hallux valgus (research group A) and without deformation (research group B), who were patients of Department of Rehabilitation, Poznan University of Medical Sciences. They performed the toe-spread-out exercises for 14 days and were examined twice: before and after exercises. The examination of participants included a surface electromyography, electroneurography and goniometer tests to measure the range of motion in the hallux joints.

Other: toe-spread-out exercise

control group

NO INTERVENTION

This arm included individuals with hallux valgus deformity from the control group which did not undergo any therapy of hallux. They were patients of Department of Rehabilitation as well. These participants were examined twice at an interval of 14 days in the same way as the patients from experimental arm.

Interventions

The therapeutic intervention lasted 14 days and focused on doing the TSO exercise. This exercise was performed unilaterally under the supervision of a qualified physiotherapist. The starting position of the TSO exercise was the sitting position with the knee joint and hip bent at 90 degrees. The exercise consisted of 3 consecutive phases: dorsiflexion of the toes keeping the metatarsal heads and the heel on the ground, moving the fifth toe down and in a lateral direction, moving the big toe down and abduction. The final position needs to be maintained for 5 seconds. The whole sequence was repeated 200 times a day.
