The effect of sequential combination of mirror therapy and robot-assisted therapy on motor function, daily function, and self-efficacy after stroke

Abstract

Robot-assisted therapy and mirror therapy are both effective in promoting upper limb function after stroke and combining these two interventions might yield greater therapeutic effects. We aimed to examine whether using mirror therapy as a priming strategy would augment therapeutic effects of robot-assisted therapy. Thirty-seven chronic stroke survivors (24 male/13 female; age = 49.8 ± 13.7 years) were randomized to receive mirror therapy or sham mirror therapy prior to robot-assisted therapy. All participants received 18 intervention sessions (60 min/session, 3 sessions/week). Outcome measures were evaluated at baseline and after the 18-session intervention. Motor function was assessed using Fugl-Meyer Assessment and Wolf Motor Function Test. Daily function was assessed using Nottingham Extended Activities of Daily Living Scale. Self-efficacy was assessed using Stroke Self-Efficacy Questionnaires and Daily Living Self-Efficacy Scale. Data was analyzed using mixed model analysis of variance. Both groups demonstrated statistically significant improvements in measures of motor function and daily function, but no significant between-group differences were found. Participants who received mirror therapy prior to robot-assisted therapy showed greater improvements in measures of self-efficacy, compared with those who received sham mirror therapy. Our findings suggest that sequentially combined mirror therapy with robot-assisted therapy could be advantageous for enhancing self-efficacy post-stroke.Trial registration: ClinicalTrials.gov Identifier: NCT03917511.

Reminiscent music therapy combined with robot-assisted rehabilitation for elderly stroke patients: a pilot study

“…These findings suggested that usual rehabilitation treatment and care plus robot-assisted rehabilitation and reminiscent music therapy, usual rehabilitation treatment and care plus robot-assisted rehabilitation, and only usual rehabilitation treatment and care could all be effective for improving self-esteem, rehabilitation self-efficacy, positive emotion, upper limb function and activities of daily living in elderly patients after stroke. These are somewhat similar to other studies [ 41 – 43 ]. The reason may be that all three interventions could effectively improve upper limb function and activities of daily living in elderly stroke patients.…”

Robotic mirror therapy for stroke rehabilitation through virtual activities of daily living

“…First, the experiments conducted here were done using healthy subjects. Future works will include studies to understand the benefits this RMT system may provide to real patients and therapists following protocols outlined in [17] , [31] . These studies will help to translate this work into a real clinical setting.…”

The Effectiveness of Robotic Mirror Therapy for Upper Limb Function Recovery after Stroke

“…Although mirror therapy did not significantly augment the effects of robot-assisted therapy on objective measures of upper limb function, stroke patients who received mirror therapy before robot-assisted therapy significantly improved their confidence in performing daily activities." (Chen et al, 2023). Moreover, RMT can trigger higher activation on the contralateral motor cortex of the affected hand compared to MT and RT, and the researcher concluded that visual and somatosensory feedback and motor intention are critical parts that lead to this result (Kim et al, 2022).…”
