Introduction: The present work was carried out to determine the effectiveness of neuromuscular stimulation triggered by mirror therapy (MT) in older patients with post-stroke hemiplegia by two different intervention protocols, either intensively or spaced. Methods: A preliminary trial conducted on Spanish rehabilitation centres was conducted. Forty older patients (>70 years) with diagnosed post-stroke hemiplegia were randomly distributed to intensive intervention group (5 times/week for 6 weeks) or to spaced intervention group (3 times/week for 10 weeks), which underwent a similar number of MT sessions (n = 30). Muscle strength and activity were measured at baseline and at the end of treatment. Functional ability was also evaluated. Results: Although both interventions improved muscle activity parameters, intensive MT showed a significantly and statistically higher intervention effect on electromyographic activity (p < 0.001) and muscle strength (p < 0.001) than the spaced over time protocol. Attending to the Barthel Index scores, the effect on functionality was also greater in the intensive therapy group (p < 0.001), although the functional improvement measured by the Fugl-Meyer test was similar (p = 0.235). The effect of the interventions was independent of age and clinical antecedents. Conclusion: Intensive MT appears to be more effective than a more spaced over time therapy; therefore, at least in the older adults, this treatment protocol should be recommended in the post-stroke recovery of these patients. Further studies will confirm with certainty whether this treatment is the most suitable guideline for to treat these patients.
