三维足踝运动干预年轻女性轻中度拇外翻的效果OA

Objective To investigate the effects of three-dimensional foot-ankle exercises(3DFAE)on mild-to-moderate hallux val-gus in young women. Methods From October to December,2024,45 female patients aged 18 to 26 years with hallux valgus were recruited from Capital University of Physical Education and Sports.They were randomly divided into control group(n=15),toe-spread-out(TSO)group(n=15)and 3DFAE group(n=15).The control group only received foot health education,while the two intervention groups performed corresponding exercise training,for four weeks.Hallux valgus angle(HVA)was measured with photographic method,abductor hallucis activation was detected with sur-face electromyography,cross-sectional area of abductor hallucis was measured with Doppler ultrasound,and ac-tive ankle dorsiflexion range of motion(ROM)was assessed with a goniometer,before intervention,immediately after intervention,and four weeks after training cessation.A perceived difficulty scale was adopted to evaluate the training difficulty of TSO group and 3DFAE group at the first training session and upon completion of inter-vention. Results The effects of time and interaction were significant for bilateral HVA,abductor hallucis activation,cross-section-al area of abductor hallucis and ankle dorsiflexion ROM(F>2.728,P<0.05),and the effect of group of left an-kle dorsiflexion ROM was also significant(F=4.995,P<0.05).After intervention,bilateral HVA,abductor hal-lucis activation,cross-sectional area of abductor hallucis and ankle dorsiflexion ROM were all better than those before intervention(P<0.05),and most indicators were superior to those measured at the 4-week follow-up(P<0.05).The left ankle dorsiflexion ROM was better in 3DFAE group than in the control group and TSO group(P<0.05).At the first intervention session,the perceived training difficulty was lower in 3DFAE group than in TSO group(t=3.334,P=0.002),and it decreased(t=5.292,P<0.001)after four weeks of training in TSO group,with no significant difference compared with 3DFAE group(P>0.05). Conclusion 3DFAE can improve ankle dorsiflexion ROM in young female patients with hallux valgus,with no more dif-ficulty than TSO,and lower initial operation difficulty.
