Remote Cognitive-Motor Training Combining Mental and Physical Practice for Freezing of Gait in Parkinson Disease: a Randomized Controlled Trial

BACKGROUNDFreezing of gait (FOG) is a disabling feature of Parkinsons disease (PD). Although physical practice (PP) improves gait, maintaining gains remains challenging. Mental practice (MP), including Dynamic Neuro-Cognitive Imagery (DNI), may enhance gait control, but evidence on remote combined interventions is limited. PURPOSETo investigate whether adding MP grounded in DNI principles to remote physical practice supports greater and more sustained improvements than remote physical practice alone in people with PD and FOG. METHODSA prospective, single-blind, parallel-group randomized controlled trial was conducted. Forty-three participants with idiopathic PD and FOG were randomized to an
