Objective:To explore the effect of task-oriented training on balance dysfunction in patients with ankle sprain.Method:Forty subjects with ankle sprain were divided into experimental group (group A) and control group (group B) according to the random number table method,with 20 cases in each group. On the basis of rou-tine training in both groups,group A was given task-oriented balance training,and group B was given bal-ance board training. Two groups of subjects performed static balance function[LOS:maximum excursion (MXE),movement velocity(MVL),reaction time (RT)],dynamic balance (Y-Balance) and Cumberland An-kle Instability Tool (CAIT) assessment before and after training for 4 weeks.Result:Before treatment,there was no significant difference in the scores of limbs between the two groups(P>0.05).After 4 weeks of training,the balance function MXE,MVL and RT scores of group A were significantly im-proved compared with those before treatment(P<0.05);but there was no significant difference in the scores of group B(P>0.05). The Y-balance scores of group A and group B after treatment were improved compared with those before treatment,and the difference was statistically significant(P<0.05). The CAIT scores of group A were improved compared with those before treatment(P<0.05),and those of group B were improved but had no signifi-cant difference(P>0.05). The changes in Y-balance and CAIT scores of group A were better than those in group B (P<0.05);there was no significant difference in the changes of LOS score between group A and group B(P>0.05).Conclusion:Task-oriented training can improve the balance dysfunction and motor function of patients with an-kle sprain.

ObjectiveTo explore the correlation among knee hyperextension angle, lower limb joints kinematics parameters and the activation of main muscles of lower limb in stroke hemiplegic patients with knee hyperextension during walking. MethodsFrom August, 2020 to September, 2021, 24 stroke hemiplegic patients with knee hyperextension and 24 healthy subjects matched with sex, age, height and body mass with knee hyperextension were analyzed with three-dimensional gait analysis system and the wireless surface electromyography acquisition system, to record the range of motion of pelvis, hip, knee and ankle joints in sagittal plane, and the activation of bilateral gluteus maximus, biceps femoris, vastus medialis and gastrocnemius medialis. ResultsAs the maximum of knee hyperextension, range of motion of the joints in sagittal plane and the activation of the muscles were different between the patients and the healthy subjects during the single-support phase of walking (|t| > 3.080, P < 0.01), and the maximum of knee hyperextension correlated with the activation of gluteus maximus in the patients (r = -0.532, P < 0.01), and the range of motion of ankle plantar flexion in both the patients and the healthy subjects (r > 0.686, P < 0.001). ConclusionThe correction for knee hyperextension gait in stroke hemiplegic patients may not only need to pay attention to knee joint control, but also need further treatment of ankle control and hip muscle function.
