Which is the most effective neurophysiologic diagonal pattern intervention for Parkinson's disease to facilitate trunk rotation during activities?

• A. Neurodevelopmental techniques
• B. Diagonal patterns
• C. Slow rolling
• D. Rolling walker

Answer: (B)

Diagonal pattern interventions target trunk rotation by engaging cross-body, multi-segmental movement that recruits the upper and lower trunk together in functional sequences. In Parkinson’s disease, axial rigidity and bradykinesia limit the ability to rotate the trunk, so training that emphasizes diagonal, cross-midline movements provides proprioceptive cues and promotes motor planning for rotational control. By guiding the body through diagonal, reciprocal patterns—where the opposite shoulder and hip move in coordination—the trunk learns to dissociate and rotate more freely during daily tasks like turning, looking over the shoulder, reaching across the body, and changing direction. This approach mirrors how people naturally move in real life, strengthening trunk mobility in a way that transfers to activities. Other options don’t specifically target this diagonal, cross-body activation. Neurodevelopmental techniques cover broader postural and movement patterns, slow rolling focuses on early sequencing rather than functional trunk rotation, and a rolling walker is an assistive device rather than a neuromotor pattern used to facilitate rotation.
