简要总结
Background: Although rehabilitation activities, including physical therapy, are known to be beneficial for stroke patients, many patients still have poor walking function, especially after the acute phase of three months, where the recovery of lower limb walking ability through traditional rehabilitation therapy gradually decreases, requiring alternative approaches. Exoskeleton robots appear to provide benefits for stroke patients by providing exercise guidance, thus improving their independent gait endurance and stair climbing ability. For stroke patients who cannot continue to improve through general rehabilitation and have ongoing mobility difficulties, exoskeletons may be a potential solution. However, previous literature on the use of exoskeletons to assist gait training has had mixed results, with one major reason being that the frequency of use is too low or the duration of use is too short, due to the high cost and inconvenience of travel to medical institutions. Therefore, it is necessary to find ways to enable patients to use them frequently and for a long period.
Method: investigators designed a non-blinded, randomized crossover trial to observe the potential benefits of using the device at home for one month. Patients were randomly divided into two groups, one receiving traditional rehabilitation first and the other using the exoskeleton first. There were four time points for testing: before, after the first stage of treatment, after the second stage of treatment, and one month after completing the second stage, to observe the sustained effects.
The testing involved executing a 6-minute walk test, timed up and go test, and a 10-step stair test (up and down) both with and without the device. An electronic software app was used to record daily usage time to determine the quantity and degree of home use.
Analysis: Repeated measures ANOVA models were used to analyze the effects and correlations of the experiment. The effects of the duration/frequency of use on dosage were also analyzed.

结局指标
主要结局
Time difference of Timed up and go' test (TUG)
时间窗: before, after the first stage of treatment, after the second stage of treatment, and one month after completing the second stage, to observe the sustained effects.
The TUG test (time measured in seconds) is a common clinical test for mobility function, using the 3-meter TUG test and following the procedure of Podsiadlo and Richardson's standards. The method involves asking the patient to sit on a straight-backed chair, then stand up, walk three meters forward at their usual pace, turn around, and return to sit on the chair. The total time is recorded with a stopwatch. The test is repeated five times. For this test, a lower score (time to complete) means better overall mobility.
Time difference of 10-step stair test
时间窗: before, after the first stage of treatment, after the second stage of treatment, and one month after completing the second stage, to observe the sustained effects.
Timed Stair Test(TST) is a timed test measured in seconds, where the participant ascends and descends 10 steps of a staircase. The time taken to ascend(TSTup) and descend(TSTdn) is measured separately using a stopwatch. A lower score on this test indicates better stair climbing performance.
final distance walked by the 6-minute walk test
时间窗: before, after the first stage of treatment, after the second stage of treatment, and one month after completing the second stage, to observe the sustained effects.
Unit in meters, used to evaluate gait function and endurance. Participants walk along a 30-meter walkway, turning back within 6 minutes and recording the total distance covered at the end. Patients are allowed to rest during the test but not run. A higher score (walking distance) indicates better gait and endurance.This range overlaps with data reported in other populations.
