Abstract:Objective To investigate the clinical effect of extracorporeal shock wave therapy (ESWT) combined with 3M physical therapy on temporomandibular joint disorder (TMD).Methods Forty patients with TMD admitted to our hospital were selected as research objects from January 2021 to October 2022, and they were divided into control group (n = 20) and observation group (n = 20) by random number table. The control group was treated with 3M physical therapy (including physical factor therapy, manual therapy and exercise therapy), and the observation group was treated with ESWT on the basis of the control group. The pain, maximum mouth opening and temporomandibular joint function were compared between the two groups before and after treatment.Results The difference between the two groups before and after treatment was statistically significant (P <0.05), and the observation group was larger than the control group. The difference between the two groups in visual analogue score (VAS) before and after treatment was statistically significant (P < 0.05). The observation group was larger than the control group. The differences between the two groups in the scores of joint murmur (JN), joint compression test (JP), mandibular movement (MM), muscle compression test (MP), and the differences of temporomandibular joint dysfunction index (DI), muscle tenderness index (PI), and Friton temporomandibular joint disorder index (CMI) before and after treatment were statistically significant (P < 0.05), and the observation group was greater than the control group.Conclusion Combined with ESWT on the basis of 3M physical therapy is beneficial to relieve the pain degree of TMD patients, increase the maximum opening limit, and promote the recovery of temporomandibular joint function.
