Clinical Observation Of MTrPs Dry Needle Inactivation Therapy Combined With Rehabilitation Training In The Treatment Of Functional Ankle Instability

Objective:To observe the clinical efficacy of dry needling in myofascial trigger points(MTr Ps)combined with rehabilitation training in the treatment of functional ankle instability(FAI),and to compare it with the clinical efficacy of acupuncture of surrounding acupoints combined with rehabilitation training for FAI.Methods: FAI patients were recruited from the Affiliated Sports Hospital of Chengdu Sports University using a randomized controlled clinical trial design,with23 cases in the experimental group and 22 cases in the control group.The experimental group received dry needling in MTr Ps combined with rehabilitation training,and the control group received acupuncture of surrounding acupoints combined with rehabilitation training.Before training and after 2 and 4 weeks of treatment,the CAIT-C score,AJFAJ score,Y-balance test score,and single-leg stance test time with eyes closed was observed and recorded.The distribution of activated MTr Ps in FAI patients,the safety and tolerability of needle insertion during treatment was also observed and recorded during the process.After the trial,the obtained data were statistically analyzed.Results: 1.No safety events such as needle bending,needle retention,needle breakage,infection,or fainting occurred during needle insertion in either group,and the pain grade of the control group was lower than that of the experimental group(p<0.05).2.Within-group comparison: as the treatment effect accumulated,the experimental and control groups gradually improved in the CAIT-C score,AJFAJ score,Y-balance test score,and single-leg stance test results,with significant differences before and after treatment(p<0.05).3.Between-group comparison: the experimental group had better results than the control group in the CAIT-C score,AJFAJ score,and Y-balance test score in the second and fourth weeks of treatment,with significant differences(p<0.05);there was no significant difference between the two groups in the single-leg stance test score in the second week of treatment(p=0.714,p>0.05),but the control group had better results than the experimental group after 4 weeks of treatment,with significant differences(p<0.05).Conclusion: 1.Dry needling in MTr Ps is generally safe and the pain after acupuncture was stronger than acupuncture of surrounding acupoints.2.Dry needling in MTr Ps combined with rehabilitation training and acupuncture of surrounding acupoints combined with rehabilitation training can both improve ankle joint stability in FAI patients.3.Dry needling in MTr Ps is more effective in improving joint dynamic stability than acupuncture of surrounding acupoints,while acupuncture of surrounding acupoints is more advantageous in improving ankle joint static stability in the later stages of treatment.
