Key result
Visuomotor simulation training and motor imagery significantly reduced HRV in the time domain in post-stroke patients, with right hemiparetic patients showing parasympathetic predominance.
Why the study?
To determine whether HRV measured during cognitive and sensorimotor upper limb tasks can serve as a biomarker of cognitive-motor interaction in post-stroke patients.
Can Heart Rate Variability (HRV) serve as a biomarker of cognitive-motor interaction during upper limb tasks in post-stroke patients?
Observational (n=46)
Can Heart Rate Variability (HRV) serve as a biomarker of cognitive-motor interaction during upper limb tasks in post-stroke patients?
HRV parameters change during cognitive-motor tasks in post-stroke patients, with differences based on lesion side, but do not correlate with clinical functional assessment scales.
May support HRV during UL tasks as post-stroke biomarker; leaves open clinical adoption pending validation.

Penati et al. (2025) conducted an observational in unilateral brain injury following stroke (n=46). Visuomotor simulation training and Motor Imagery vs. Rest was evaluated on Heart Rate Variability (HRV) in time and frequency domains. Visuomotor simulation training and motor imagery significantly reduced HRV in the time domain in post-stroke patients, with right hemiparetic patients showing parasympathetic predominance.
