Abstract
Background: Stroke survivors can remain impaired in body functions, activity, and
participation. A novel rehabilitation regimen is required to obtain scientific evidence
and to help clinicians determine effective interventions for stroke. Mirror therapy (MT)
and bilateral upper limb training (BULT) are based on the tenet of bilateral movement
practice; however, the additional effect of bilateral robotic priming combined with these
two therapies is unclear.
Objectives: This study examined the effects of two hybrid therapies, robotic priming
combined with MT and robotic priming combined with BULT, in stroke survivors.
Methodology: The study randomized 31 participants to groups that received robotic
priming combined with MT (n = 15) or robotic priming combined with BULT (n = 16).
Outcome measures included the Fugl–Meyer Assessment (FMA), the revised Nottingham
Sensory Assessment (rNSA), the Chedoke Arm and Hand Activity Inventory (CAHAI), and
accelerometer data.
Results: Both groups showed statistically significant within-group improvements in most
outcome measures. Significant between-group differences and medium-to-large effect
sizes were found in favor of the group that received robotic priming combined with MT
based on the FMA distal part subscale scores, FMA total scores, and accelerometer data.
Conclusion: Robotic priming combined with MT may have beneficial effects for patients
in the improvements of overall and distal arm motor impairment as well as affected arm
use in real life. Additional follow-up, a larger sample size, and consideration of the effect
of lesion location or different levels of cognitive impairment are warranted to validate our
findings in future studies.
