Abstract

Purpose: This study aimed to determine the most effective way to facilitate the abductor hallucis muscle during PNF leg pattern-emphasized hallux abduction. Methods: The study recruited 18 healthy adults. All participants agreed voluntarily to take part in the study following an explanations of its purpose and procedures. They randomly performed the PNF leg pattern-emphasized hallux abduction variations in a hook-lying or sitting position. Activation of the abductor hallucis (AbH), adductor hallucis (AdH), extensor hallucis longus (EHL), and tibialis anterior (TA) muscles, and the ratio of AbH/AdH, were measured during PNF exercises using electromyography. One-way repeated ANOVA was used to compare the activation of foot intrinsic and extrinsic muscles during the four PNF exercises. Results: PNF leg pattern-emphasized hallux abduction using normal timing was significantly higher in TA compared to PNF leg pattern-emphasized hallux abduction using timing for emphasis, regardless of the starting position. The PNF leg pattern-emphasized hallux abduction using timing for emphasis in the hook-lying position was significantly higher in AbH than in other exercises. Although there was no statistically significant difference in the ratio of AbH/AdH, it was higher in the hook-lying position. Conclusion: PNF leg pattern-emphasized hallux abduction using timing for emphasis in the hook-lying position can be recommended as a method to optimize the activation of AbH and the ratio of AbH/AdH.
