Abstract:Objective To investigate the clinical effect of internal heated needle in the treatment of plantar fasciitis. Methods A total of 56 patients with plantar fasciitis were randomly divided into treatment group and control group. The patients in the treatment group were given internal heated needle therapy, and those in the control group were given blocking therapy. Before treatment, after 2 weeks of treatment, and at 2 months after treatment, the Visual Analogue Scale (VAS) was used to evaluate the degree of foot pain, and the American Orthopaedic Foot and Ankle Society-Ankle-Hindfoot Scale (AOFAS-AHS) was used to assess foot function. Results After 2 weeks of treatment and at 2 months after treatment, both groups had a significant reduction in VAS score (P<0.05) and a significant increase in AOFAS-AHS score (P<0.05). After 2 weeks of treatment, there were no significant differences between the two groups in VAS and AOFAS-AHS scores (P>0.05). At 2 months after treatment, the treatment group had a significantly lower VAS score and a significantly higher AOFAS-AHS score than the control group (P<0.05). Conclusion Both internal heated needle therapy and blocking therapy have a good short-term clinical effect in the treatment of plantar fasciitis, while internal heated needle therapy has a better long-term effect than blocking therapy.
