Background: Precision-Based Motor Learning (PBML) focuses on task accuracy, sensory feedback, and controlled motor repetition, aimed at promoting neuroplasticity after stroke. Evidence suggests that targeted motor learning strategies may enhance cortical reorganization and functional recovery.
Objective: To evaluate the effects of PBML on neuroplastic adaptations and upper-limb motor recovery in individuals with post-stroke impairment.
Methods: Thirty-six participants with chronic stroke were randomly allocated to either PBML training (N=18) or conventional motor practice (N=18). Both groups trained 5 days/week for 8 weeks. Outcome measures included Fugl-Meyer Upper Extremity (FMA-UE), grip strength, Box and Block Test (BBT), and somatosensory discrimination tasks. Pre-post scores were analyzed using paired and independent t-tests (p<0.05).
Results: The PBML group demonstrated significantly greater improvements in motor coordination, sensory accuracy, and fine-motor control. FMA-UE increased by 17.2 points in the PBML group compared with 10.4 points in the control group. Grip strength improved by 5.1 kg versus 2.3 kg, and BBT scores increased by 34% versus 18% in controls (all p<0.05).
Conclusion: PBML resulted in superior neuroplastic and functional gains compared with conventional motor practice. These findings support the integration of precision-based training into upper-limb stroke rehabilitation.
