ObjectiveTo explore the rehabilitation effect of a domestic lower limb rehabilitation robot on patients with chronic stroke.MethodsChronic stroke patients who were hospitalized in the Department of Rehabilitation Medicine, the First Affiliated Hospital of Chongqing Medical University from September 2017 to August 2019 were collected. These patients underwent A3 robot-assisted gait training for 6 weeks. The differences of gait parameters, spatiotemporal asymmetries, total score and score of each item of Barthel Index were analyzed before and after 6 weeks training.ResultsA total of 15 patients were included, and 12 patients finally completed the trial. After the training, the gait parameters of patients with chronic stroke were significantly improved. Comparing with the baseline data, the cadence, stride length, velocity, step length of the affected leg, and step length of the healthy leg significantly increased (P<0.05) after the training; the stride time and the double-support time were significantly shorter (P<0.05); the stance phase of the affected leg was shortened (P<0.05); the swing phase of the affected leg was prolonged (P<0.05); While no significant difference in the stance phase or swing phase of the healthy leg was found (P>0.05). The spatiotemporal asymmetries had no significant change compared with the baseline data, including the ratio of step length [(1.26±0.23) vs. (1.13±0.10); t=1.816, P=0.097] and the ratio of swing phase of both lower limbs [1.14 (0.23) vs. 1.10 (0.38); Z=−0.153, P=0.878]. The activities of daily living were improved after the training, and the total score of Barthel Index [(72.92± 13.05) vs. (85.42±14.38); t=−6.966, P<0.001] was significantly higher than that before the training. Among the items, the scores of bathing [0.00 (3.75) vs. 5.00 (5.00); Z=−2.000, P=0.046], walking on the flat ground [10.00 (3.75) vs. 15.00 (5.00); Z=−3.000, P=0.003], and going up and down stairs [5.00 (5.00) vs. 7.50 (5.00), Z=−3.000, P=0.003] were higher than the baseline data, and the differences were statistically significant.ConclusionsA3 robot-assisted gait training can effectively improve the walking ability and activities of daily living of patients with chronic stroke but not the spatiotemporal asymmetries. Whether the spatiotemporal asymmetries can be improved by adjusting the robot equipment parameters needs to be further studied.
Objective To investigate the effect of lower limb rehabilitation robot combined with virtual reality training on walking ability after anterior cruciate ligament reconstruction (ACLR). Methods Patients after ACLR treated in the Rehabilitation Medical Center of the Second Hospital of Jiaxing between May 2019 and July 2021 were selected. The patients were randomly divided into two groups. The patients with conventional ACLR rehabilitation training + lower limb rehabilitation robot combined with virtual reality training were used as the treatment group, and only the patients with conventional ACLR rehabilitation training were used as the control group. The rehabilitation training lasted for 8 weeks. After 4 and 8 weeks of treatment, the two groups were evaluated by Lysholm knee score scale (LKSS), Holden walking score and Gait watch gait analysis. Results A total of 40 patients were included, with 20 patients in each group. There was no significant difference between the two groups in LKSS score, Holden walking score and Gait watch gait analysis dynamic data at 4 weeks of treatment (P>0.05). After 8 weeks of treatment, the LKSS score [(77.74±5.53) vs. (69.53±5.26) points], Holden walking score [(4.79±0.34) vs. (4.45±0.39) points] and Gait watch gait analysis dynamic data [step size: (78.35±2.43) vs. (73.64±3.35) cm, step frequency: (115.10±4.49) vs. (107.71±5.14) step/min, step speed: (108.63±8.55) vs. (96.78±8.47) cm/s] of the treatment group were better than those of the control group (P<0.05), The above indexes of the two groups were improved compared with those at 4 weeks of treatment (P<0.05). Conclusion Lower limb rehabilitation robot combined with virtual reality training can effectively improve walking ability after ACLR.
