Background and Objectives: Facial paralysis involves the complete or partial loss of facial movement due to damage to the facial nerve, leading to impaired voluntary muscle function and facial asymmetry. Given its significant physical and psychosocial impact, there is an urgent need to strengthen the evidence supporting non-pharmacological treatments. This umbrella review aims to compile the most reliable and current data to establish a consensus on the effectiveness of such interventions for patients with facial paralysis. Materials and Methods: This study is an umbrella review. A systematic search was conducted in PubMed, Embase, Scopus, and CINAHL (28 July 2024). The variables assessed included overall healing/recovery rate, facial disability, and facial function. Methodological quality was evaluated using the AMSTAR and ROBIS tools. Screening was performed independently by two reviewers, with a third reviewer resolving any discrepancies. Results: Five systematic reviews were included, all evaluating the impact of non-pharmacological interventions in facial paralysis. The findings suggest that acupuncture and electrical stimulation may improve recovery rates and facial function, although high heterogeneity and methodological limitations were noted in some studies. No definitive conclusions could be drawn regarding facial disability. Conclusions: The combination of electrotherapy with other complementary techniques, such as facial exercises or laser therapy, appears to be a safe and potentially effective approach for facial paralysis rehabilitation. Nonetheless, further research employing standardized protocols and higher methodological quality is necessary to establish more robust conclusions for physiotherapeutic practice.

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. For post-video observation, participants replicated the observed actions three times without specific performance instructions, allowing for the assessment of their execution speed. Results: The analysis revealed that individuals observing actions at a faster pace executed the subsequent motor tasks significantly quicker than their counterparts who viewed the same actions at a slower speed. This was consistent across both NSCLBP sufferers and asymptomatic subjects, indicating that the action observation (AO) speed directly influenced the execution speeds of lumbar flexion and TUG test movements. Conclusions: The findings demonstrate that AO speed significantly affects the pace of motor execution, irrespective of NSCLBP presence. This underscores the potential of utilizing varied AO speeds as a strategic component in clinical practice, particularly for enhancing motor planning and execution in physical therapy settings. The study highlights the importance of incorporating AO speed variations into therapeutic interventions for improving patient outcomes in motor task performance.
