Proprioceptive neuromuscular facilitation combined with core stability training can help relieve functional an-kle instability

目的观察本体感觉神经促进技术（PNF）联合核心稳定性训练对功能性踝关节不稳（FAI）患者下肢功能康复的影响。方法选取FAI患者20例，按随机数字表法分为实验组和对照组，每组患者10例。2组患者均采用常规康复训练，对照组在此基础上增加躁关节肌力训练和本体感觉训练；实验组则在常规康复训练的基础上增加PNF联合核心稳定性训练。2组患者均于治疗前和治疗12次后（治疗后）采用Cumberland踝关节不稳定评价问卷（CAIT）、踝关节等速向心肌力测试、踝关节本体感觉测试、星形偏移平衡测试（SEBT）进行评定。结果治疗后，2组患者的CAIT评分与组内治疗前比较差异均有统计学意义（P〈0．01），且实验组治疗后的CAIT评分与对照组比较，差异亦有统计学意义（P〈O．05）。治疗后，2组患者的踝关节等速肌力测试、本体感觉测试与组内治疗前比较，差异均有统计学意义（P〈O．05）。治疗后，实验组SEBT测试各项数值与组内治疗前比较，差异均有统计学意义（P〈0．05），且实验组治疗后的外后（PLAT）、后（POST）、内后（PMED）、内（MediM，MED）、内前（AMED）5个方向上SEBT测试数值与对照组治疗后比较，差异均有统计学意义P〈0．05）。结论PNF联合核心稳定性训练可改善FAI患者踝关节的功能（肌力和本体感觉）和下肢动态平衡能力。

Objective To observe the effect of proprioceptive neuromuscular facilitation （PNF） technology combined with core stability training on the rehabilitation of patients with functional ankle instability （FAI）. Methods Twenty FAI patients were randomly divided into an experimental group and a control group, each of 10. The control group was given routine rehabilitation together with ankle strengthening training and proprioeeption train- ing. The experimental group was provided with PNF combined with core stability training in addition to the routine re- habilitation. Before and after the 12 training sessions, both groups were evaluated using the Cumberland ankle insta- bility tool （ CAIT）. The strength of their ankle flexors and extensors was measured in isokinetic concentric contrac- tion, ankle proprioception was tested and the star excursion balance test （SEBT） was administered. Results Before the intervention there were no significant inter-group differences in any of the measurements. Afterward, significant improvements were observed in the first three tests, with the experimental group＇s average improvement significantly better than that of the control group. All of the SEBT measurements were significantly better than before the treatment, with significant differences between the two groups in the posterolateral, posterior, posteromedial, medial and antero- medial directions. Conclusion PNF technology combined with core stability training can improve ankle strength and proprioception and the dynamic balance of FAI patients.
