The Effects of Action Observation Speed on Motor Function in Patients with Chronic Low Back Pain: From Observation to Execution.

Objective: The objective of this study was to examine the effect of observing actions at different speeds on the speed of motor task performance in subsequent actions.

Methods: Sixty individuals, divided equally between those with non-specific chronic low back pain (NSCLBP) and asymptomatic subjects, were enrolled. Participants were further split into subgroups to observe lumbar flexion and Timed Up and Go (TUG) test actions at either a slow or fast pace, following a randomized assignment.

Exploring temporal congruence in motor imagery and movement execution in non-specific chronic low back pain.

Chronic non-specific low back pain (NSCLBP) is linked to sensorimotor dysfunctions and altered motor planning, likely due to neuroplastic changes. Motor imagery (MI) and movement execution share neural pathways, but the relationship between imagined and executed movements in NSCLBP patients remains underexplored. This study aimed to assess the temporal congruence between imagined and executed movements in NSCLBP sufferers, with secondary goals of investigating group differences in movement chronometry, psychological well-being, and disability, as well as possible correlations among these factors.
