| Objective: To study the effect of Lokomat lower limb rehabilitation robot training duration on the improvement of walking function in stroke patients with hemiplegia at different walking function levels, and to provide basis for the selection of lower limb rehabilitation robot treatment for stroke patients with hemiplegia. Methods: A total of 120 stroke patients with hemiplegia were collected. Patients evaluated with functional walking scale (FAC) 0 and 1 were included in the low level walking function group, and those evaluated with FAC 2 and 3 were included in the high level walking function group, with 60 cases in each group. Each group was further divided into 20 min subgroup, 30 min subgroup and 40 min subgroup according to the training time of lower limb robot, with 20 cases in each subgroup. All patients in the 6 groups received 4 weeks of routine training plus step robot training. The scores of the simplified Fugl-Meyer Motor Function Scale (FMA), Berg Balance Scale (BBS) and Functional Walking Scale (FAC) were compared before and after treatment. Results: The differences of FMA, BBS and FAC scores in the 6 groups before and after treatment were significantly different within the group (P<0.01), but in the low level walking function group, the improvement of FMA, BBS and FAC scores in patients with shorter limb robot training duration of 20 min was more obvious than that in those with 30 min or 40 min of training. The results of FMA, BBS and FAC in the high level walking function group with training duration of 40 min were significantly improved (P<0.05). Conclusion: Different walking training duration of Lokomat lower limb robot can affect the walking function of hemiplegic stroke patients. In patients with low walking function level, walking for 20 min can achieve better training effect, while in patients with high walking function level, walking for 40 min has better rehabilitation effect, which is worthy of clinical promotion and application. |
