BACKGROUND: The traditional ankle-foot orthosis focuses on the protection, correction, stability, and compensation;therefore, it is important to explore a new rehabilitation method for ankle joint dysfunction.OBJECTIVE: To explore the effect of computer-aided movable and measurable ankle-foot orthosis that designed by the Department of Rehabilitation in Longgang Central Hospital of Shenzhen on postoperative dysfunction after ankle fracture.METHODS: Fifty-two patients with ankle fractures at 3 weeks after internal fixation were selected and equivalently randomized into two groups. Both groups received conventional oral medication and rehabilitation therapy. In addition,the patients in control group were given joint mobilization treatment, while those in experimental group were given computer-aided movable and measurable of ankle-foot orthosis, 20 minutes daily, 6 days weekly for consecutive 4 weeks. The efficacy was evaluated by muscle strength, active range of motion, Kofoed ankle score and visual analogue scale on computer at baseline, 7, 14, and 28 days after training.RESULTS AND CONCLUSION: (1) There were no significant differences in baseline data and ankle function scores between two groups before training (P > 0.05), and all above indicators were significantly improved in both two groups at 4 weeks after training (P < 0.05). (2) Compared with the control group, the muscle strength, Kofoed ankle score and visual analogue scale scores on computer in the experimental group were significantly improved at 7, 14 and 28 days after training (P < 0.05). (3) The active plantar flexion angle in the experimental group was significantly larger than that in the control group at 28 days after training (P < 0.05).The active plantar flexion and dorsiflexion angles at 7 and 14 days after training, and active dorsiflexion angle at 28 days after training did not differ significantly between two groups (P >0.05). To conclude, the unique ankle-foot orthosis can reduce postoperative pain, enhance muscle strength and improve ankle mobility after ankle fracture.

Objective To study the incidence of depression in essential tremor (ET) and associated factors. Methods Depression in 62 ET patients and 60 healthy subjects as control was evaluated by means of Hamilton Depression Scale ( HAMD ) , as well as Fahn-Tolosa-Marin Tremor Rating Scale (TRS) and Pittsburgh Sleep Quality Index (PSQI). Results Fifty-three point two percent(33/62) of ET patients and 11.7% (7/60) of healthy subjects were found to have at least mildly depression (HAMD score of 8 or higher), 35. 5% (22/62) of ET patients and 8. 3% (5/60) of healthy subjects fell into the mildly-to-mederately depression (HAMD score between 8 and 20 ), 17.7% (11/62) of ET patients and 3.3% (2/60) of healthy subjects were classified into moderately-to-severely depressed range (HAMD score between 21 and 35). There were statistical differences in ET group and healthy subjects group (X2= 23.898, 13.043, 6.649, all P <0.01). Additionally, there were statistical differences in anxiety/ somatization (t=-6.747, P<0.01), cognitive impairment (t=-2.017, P=0.05), block(t= -4.145, P<0.01), sleep disorders (t=-4.500, P<0.01) and despair (t=-3.591, P<0.01) between depression group and non-depression group. There were marked differences in PSQI total score ( t =-3.196, P=0.003 ), subjective sleep ( F1, t=-3.037, P=0.004), quality sleep latency (F2, t= -4.674, P<0.01) and sleep disturbances (F5, t=-2.594, P=0.013 ) between depression disorder group and non-depression disorder group. Meanwhile, the score of TRS, PSQI and sex were closely correlated with HAMD (β=0.589, P=0.000 ;β=0.469,P=0.000 ;β=0.256, P=0.027 ). Conclusions The incidence of depression is high in ET. Manifestation of depression are anxiety, reduced interest in work, sleep disorders, retardneas, inferiority complex, etc. The degree of symptoms relates to the severity of ET, sleep quality and gender.
