Abstract
Study design: Case report. Objectives: To report a case where a monoplegic patient received L-DOPA and/or buspirone. These compounds, normally used in the treatment of Parkinson's disease and anxiety respectively, were recently shown to induce spinal locomotor network activity and reflex stepping-like movements in animal models of spinal cord injury (SCI). However, the safety of these drugs as potential treatments for Central Pattern Generator (CPG) activation in paralyzed individuals remain unclear. Setting: St-Jean-Chrysostome, Quebec, Canada. Method: The acute effects induced by these compounds were qualitatively assessed by the patient, a 38-year-old man who underwent surgery 17 years ago to remove an intracavernous angioma located at the mid-thoracic level (T5-T6) of the spinal cord. Results: Self-administration every 2 days of L-DOPA (200, 400 and 600 mg, p.o.) and buspirone (5, 10 and 15 mg, p.o.) either separately or combined led to no atypical side effects (that is, occasional sleepiness, nervousness, insomnia or mild headaches). No movement was induced ipsilaterally although some sensations referred to by the patient as an increased blood flow in the lower back and upper leg regions were reported shortly after administration of the combined treatment. Conclusion: The results show no significant side effects following acute administration of L-DOPA and/or buspirone. This constitutes the first report providing preliminary evidence of safety following administration of these drugs in incompletely paralyzed individuals. The sensations of increased blood flow ipsilaterally with the combined treatment may also suggest that the dose regimen was not optimal or sub-threshold for inducing detectable CPG-mediated leg movements.
