The Influence Of 4 Weeks PNF Training On The Dynamic Balance Ability Of Functional Ankle Instability Patients

Objective:To investigate the influence of dynamic balance ability on the patients with the functional ankle instability (FAI), and to observe the influence of the proprioceptive neuromuscular facilitation techniques (PNF) training on dynamic balance ability of the FAI patients.Methods:56 subjects were recruited, including 28 patients with functional ankle instability (Group F),28 people without injure (Group H). Group F accepted PNF technique training,3 times per week and for 4 weeks. PNF training includes:combination of lower extremity isotonic D2 model portfolio, combined with the stability of lower limb model D2 flip, ankle dorsiflexion and toe flexion varus valgus rhythmic stabilization techniques, each action of each training cycle to 3 groups 10. H group was not on any intervention, only groups of indicators for F normal controls. Before and after training on the F MJS balance tester dynamic balance ability of the test group, H group only tested once before the experiment. Test indicators include:left/right foot overall stability index, stability index and so steady before and after the index. Statistical analysis of test results, compared to patients with functional ankle instability and dynamic balance ability does not hurt the differences between people, and 4 weeks of PNF training methods of functional ankle instability on dynamic balance ability of patients.Results:(1)before training, compared with Group H, the dynamic balance ability of the injured side had had a very significant difference (p <.01), and the, and the normal side had significant difference (p<.05). (2) For Group F, Before training, the index of left/right foot overall stability and anterior-posterior stability had significant difference (P<.05) between the injuried and normal sides, the index of left-right stability had no difference. (3)The dynamic balance ability of Group F's injuried side had a very significant difference (p<.01)between before and after the training. (4)After the 4-week PNF manual training, the dynamic balance ability of Group F's normal side had a very significant difference (p<.01) compared with the beginning.(5) After the 4-week PNF manual training, Group F's both sides had no difference compared with the Group H, and there was no difference between the injuried and normal side.Conclusion:(1) The dynamic balance ability of the patients with functional ankle instability (FAI) was weaker than the uninjuried people-significantly, and the injuried side was worse than the normal side. (2)4-week PNF training not only significantly improved the dynamic balance ability of injuried side for the FAI patients, and it was effective enough to improve the dynamic balance ability of injuried side to the normal level. (3) 4-week PNF manualtraining pointing at the injuried side of FAI patients, also had the capacity to improve the dynamic balance of the normal side and reach the level of uninjured people, and thers was no difference between the injuried and normal sides in the dynamic balance ability.论文随机验证编号:BT674011164037...
