Comparative Study on the Intervention Effect of Different Physical Therapies on Functional Ankle Instability
Objective:This study aimed to compare the effects of Maitland joint mobilization and proprioceptive neuromuscular fa-cilitation(PNF)training interventions on functional ankle instability(FAI).Methods:A total of thirty participants with FAI were recruited and randomly assigned to either the joint group(n=15)or the PNF group(n=15).Both groups received routine reha-bilitation training consisting of muscle strength and balance exercises.Additionally,the joint group underwent Maitland joint mo-bilization three times a week for eight consecutive weeks,while the PNF group received isotonic combination training and stability inversion training in addition to the routine rehabilitation.Pre-and post-intervention assessments were conducted for both groups,including the Star Excursion Balance Test(SEBT),muscle strength assessment,postural control ability assessment,and Cumberland Ankle Instability Tool(CAIT),to evaluate balance,muscle strength,postural control,and ankle joint function.Results:Both groups demonstrated significant improvements in balance,muscle strength,postural control,and ankle joint func-tion after the treatment(P<0.05)comparedtobaseline.Thejointgroupexhibitedsuperiorperformancein SEBT-Aand SEBT-C compared to the PNF group.On the other hand,the PNF group showed greater improvement in dorsiflexion and plantarflexion muscle strength compared to the joint group.Furthermore,the joint group demonstrated better frequency,amplitude,and oscilla-tion coefficient,resulting in statistically significant differences(P<0.05)when compared to the PNF group.Conclusion:Both joint mobilization and PNF training interventions were found to enhance balance,muscle strength,and postural control in patients with FAI.Joint mobilization demonstrated an advantage in terms of improving balance and lower limb postural control,while PNF training had a greater impact on enhancing muscle strength around the ankle.
