Objective To explore the factor structure of the anxiety imagery characteristics questionnaire.Methods Through the literature review and expert group discussion,the initial anxiety imagery features questionnaire was created.The first questionnaire contained 49 items of anxiety imagery,which was answered by 106 imagery dialogue psychotherapists.After analysis of the items and exploratory factors,the formal questionnaire that contained 20 items of anxiety imagery characteristics was formed.The formal questionnaire was measured by 115 imagery dialogue psychotherapists,then,exploratory and confirmatory factor analyses were made.Results The exploratory factor analysis showed that four factors whose Eigen value were more than 1 were extracted from l0 items,including emotional panic,uneasy,tense muscles,and motor restlessness.Those four factors explained 54.39％ of the total variance.Confirmatory analysis showed that x2/df was 2.142 ; root mean square error of approximation (RMSEA) was 0.059 ; and comparative fit index (CFI),goodness-of-fit index (GFI),non-normed fit index (NNFI) and RSMEA was 0.912,0.935,0.896,and 0.057,respectively.Conclusions The four-factor structure was constructed by 10 items of anxiety imagery characteristics questionnaire.

Objective To observe the effect of surface electromyographic biofeedback (sEMG BFB) combined with routine swallow training in treating dysphagia among those with nasopharyngeal carcinoma after radiation therapy.Methods Fifty dysphagic patients with nasopharyngeal carcinoma after radiation therapy were randomly divided into a biofeedback training group and a routine treatment group,each of 25.Both groups were given routine training including orofacial function training,sensory irritation,behavioral swallowing training,and electrical stimulation.The biofeedback group was additionally given behavioral swallowing training based on sEMG BFB.Before and 4 weeks after the treatment,a videofluoroscopic swallowing study was performed to observe the opening of the upper esophageal sphincter (UES).The penetration aspiration scale (PAS) and the functional oral intake scale (FOIS) were used to evaluate the subjects' swallowing function.Results Before the treatment there were no significant differences between the two groups in terms of UES opening,average PAS score or average FOIS score.Everyone improved significantly after the treatment,but compared with the routine treatment group,UES opening was significantly better after the treatment,the average PAS score was lower and the average FOIS score was higher in the biofeedback training group.Conclusion sEMG BFB combined with routine swallowing training can improve the UES opening and swallowing ability of dysphagic patients with nasopharyngeal carcinoma after radiation therapy.

Objective:To analyze the short-term therapeutic efficacy of radial extracorporeal shock wave therapy for patients with subacromial impingement syndrome.Methods:A total of 106 patients diagnosed as having subacromial impingement syndrome between October 2017 and April 2019 were randomized into a radial extracorporeal shock wave therapy (rESWT) group of 36, an exercise rehabilitation group of 35 and a conventional therapy group of 35. In addition to family exercise therapy, the rESWT group underwent 2000 to 2500 shots of extracorporeal shock wave therapy at 10 Hz and a pressure of 1.5-2.5 bar, once a week for four consecutive weeks. The exercise group was given range of motion exercises, joint control training and tendon movement training for 45 minutes, three times a week for four consecutive weeks. The conventional therapy group was treated with a laser apparatus and low-frequency electrotherapy, once a day, three times a week. Constant-Murle scores (CMSs) and the short form health survey (SF-36) were used to evaluate the clinical efficacy before and after 1 month of treatment.Results:Before the treatment there were no significant differences among the 3 groups in any of the measurements. After one month of treatment the average CMS pain score and total score of the exercise rehabilitation group were significantly better than the conventional therapy group′s averages. Moreover, the average body pain score, daily life ability, range of motion, muscle strength and total score of the rESWT group were all significantly better than the exercise and conventional therapy groups′ averages. In the SF-36 the average physical function, bodily pain, general health, and mental health scores of the rESWT groups were also significantly better than the other 2 groups′ averages.Conclusions:Radial extracorporeal shock wave therapy is superior to exercise therapy and conventional therapy for patients with subacromial impingement syndrome. It can restore shoulder joint function and improve the quality of life in one month.
