ObjectiveTo assess the value of comfortable and maximum walking speed of outcome measuring for locomotion recovery after stroke.Methods10m walking speed of 32 stroke subjects who were able to walk independently were tested in the freely chosen and maximum. The motor function of the paretic lower limb and balance were evaluated with the Fugl-Meyer Assessment,Berg Balance Scale and ambulatory item of Functional Independence Measure. The level of association between gait speeds and the clinical variables were examined with Pearson's correlation coefficients.ResultsComfortable walking speed were significantly positively related to maximum walking speed(r=0.953,P<0.001),and balance, motor function of the lower limb and ambulatory function were significantly positively related to comfortable and maximum walking speed(r=0.742-0.834,P<0.001).The relationship between comfortable walking speed and clinical variables was higher(r=0.787-0.834,P<0.001).Conclusions Both comfortable and maximum walking speed can reflect locomotion recovery after stroke, but comfortable walking speed is more pragmatic,securer and more sensitive.

Objective To analyze the effect of limited internal fixation contrasting micro -external fixator in the treatment of fractures around the hand.Methods Sixty patients with fractures around the hand treated in the First People′s Hospital of Huizhou from May 2015 to May 2017 were selected and randomly divided into the internal fixation group and the external fixation group,and then were treated with effective internal fixation and mini external fixator respectively.The curative effect,operation condition,postoperative recovery and complications of the two groups were compared.Results The treatment effect(excellent and good rate was 96.67%(29/30)),fracture recovery time((6.37 ± 1.25)weeks),hospitalization time((4.32 ±1.23)d)and postoperative complication rate(10.0%(3/30))in the external fixation group were superior to those in the internal fixation group(76.67%(23/30),(8.87 ± 2.12)weeks,(7.29 ± 2.15)d,33.3%(10/30)),the differences were statistically significant(P=0.032;t=15.459,P=0.005;t=17.788,P =0.001;P=0.012).However,there were no significant differences between the external fixation group and internal fixation group in the operation time and the blood loss during operation((28.41±2.87)min vs.(27.67±1.42)min;(16.87 ± 3.71)ml vs.(16.43 ± 2.89)ml)(t=2.459,P=0.423;t=1.788,P =0.619). Conclusion Compared with limited internal fixation,the mini external fixator is reliable and effective,with less complications,and is more conducive to the early activity and functional recovery of the patients with hand fractures.
