Physiotherapy rehabilitation of the smile after long-term facial nerve palsy using video self-modeling and implementation intentions.
OBJECTIVE
To improve smiling after long-term facial nerve palsy (FNP). Physiotherapy rehabilitation of an adapted (more symmetrical) smile was investigated in FNP subjects 1 year post-onset, using video self-modeling (video replay of only best adapted smiles) and implementation intentions (preplanning adapted smiles for specific situations).


METHODS
Prospective, blinded clinical trial. Facial-Nerve-Palsy Clinic.


RESULTS
After video self-modeling: 1) reaction time (RT) to initiation of adapted smiles became 224 ms faster whereas RT for everyday (asymmetrical) smiles became 153 ms slower; 2) adapted smiles were completed 544 ms faster; 3) adapted smiles had higher overall quality, movement control, and symmetry ratings; and 4) Facial Disability Index scores also improved. Implementation intentions after video self-modeling ensured transfer of adapted smile to everyday situations.


CONCLUSIONS
Following intervention the smile improved, with significant changes in availability, execution speed, and quality.


CONCLUSIONS
This study supports these rehabilitation techniques to maximize quality of smiling following FNP.
