Objective: To analyze the behavior of patellar reflexes in four Parkinson’s Disease patients undergoing an acupuncture treatment protocol.

Background: The investigation of rigidity physiology in Parkinson’s Disease (PD) involves the examination of reflexes. Parkinsonian patients often demonstrate reduced sensitivity in polysynaptic reflexes within the leg extensor muscles, which is correlated with their postural instability. The compensatory mechanisms for impaired proprioceptive reflex function may involve alterations in intrinsic muscle stiffness. The interplay between gait and reflexes is intricately linked to the nervous system’s functioning and motor control. Certain reflexes, such as patellar reflexes, play a pivotal role in maintaining walking and posture. Ensuring the integrity of these reflexes is essential for facilitating smooth and efficient walking.

Method: This study adopts a case series design. Reflex outcomes were assessed at six different time points throughout a month-long treatment protocol using MP 36, Biopac Systems.

Results: Positive differences were observed in cumulative effects across all patients, indicating a tendency for improvement over the long term. Nevertheless, in specific cases, there was a trend towards a reduction in the area during acute effects.

Conclusion: Our findings suggest that the acupuncture protocol may lead to a cumulative improvement in the range of motion (ROM) of patellar reflexes in patients with Parkinson’s disease. Further in-depth research, including a statistical evaluation with a larger participant pool, is necessary to validate and confirm these promising results conclusively.
