OBJECTIVE: To evaluate the clinical efficacy of ultrasound-guided acupuncture at myofascial trigger points (MTrPs) on treating post-stroke foot drop. METHODS: Sixty patients with post-stroke foot drop were randomly assigned to an observation group 1 (20 cases, 1 case dropped out), an observation group 2 (20 cases, 2 casses dropped out), and a control group (20 cases). The control group received conventional acupuncture at Yanglingquan (GB34), Jiexi (ST41), Taichong (LR3), Zusanli (ST36), Xuanzhong (GB39), and Qiuxu (GB40) on the affected side, once daily. In addition to the treatment of the control group , the observation group 1 received acupuncture at the tibialis anterior and gastrocnemius MTrPs, once every other day, while the observation group 2 received ultrasound-guided acupuncture at the tibialis anterior and gastrocnemius MTrPs, once every other day. All groups were treated for two weeks. Three-dimensional gait analysis was performed using an infrared motion capture system, and the Holden walking scale was used to evaluate walking ability before and after treatment in the three groups. RESULTS: Compared before treatment, the patients in the observation groups 1 and 2 showed increased walking speed (P<0.05, P<0.01), and improved Holden walking scale grades (P<0.05, P<0.01) after treatment; the patients in the observation group 2 also showed increased ankle dorsiflexion angles (P<0.05). The walking speeds of the observation groups 1 and 2 were faster than those of the control group after treatment (P<0.05), the Holden walking scale grade in the observation group 2 was superior to that in the control group (P<0.05). CONCLUSION The ultrasound-guided acupuncture at MTrPs could effectively improve gait function in post-stroke foot drop patients.

OBJECTIVE: To test the validity and reliability of the Chinese version of Mobile Phone Involvement Questionnaire (MPIQ) in college students. METHODS: We assessed the degree of phone dependence using the MPIQ among 2122 college students. One month later, 60 students were randomly selected for assessment with the MPIQ, and the ROC curve was generated to evaluate the true positive rate (sensitivity) and false positive rate at different cutoff values to determine the optimal cutoff score of the MPIQ. RESULTS: Among 98.9% of the participants who finished all the items, their MPIQ scores show a positive skew distribution and a one-factor structure. The load scores of the items ranged from 0.54 to 0.77. The Cronbach's α coefficient and the Spearman Brown split reliability were 0.84 and 0.83, respectively, the correlation coefficients between the items and total score ranged from 0.54 to 0.76, and the test-retest reliability was 0.48 ( < 0.001). At the optimal cut-off score of 32, the sensitivity and the specificity of the MPIQ were 0.634 and 0.652, respectively. CONCLUSIONS At the optimal cut-off score of 32, the MPIQ has good validity and reliability for assessing phone dependence among college students.
