High frequency stimulation of spinal cord may benefit Parkinson's patients, a new study claims.
Ming Cheng, MD, is a neurosurgeon at Rhode Island Hospital and the lead author says that findings from earlier studies wherein spinal cord stimulation (SCS) had improved motor functions of patients, prompted them to test SCS on a single 82-year-old male with PD.
Advertisement"Our study shows no changes in pain assessment to control for reduction in pain as the reason for motor improvement," says Cheng.
"What we did find is that low-frequency SCS produced a readily apparent and statistically significant worsening of Parkinson's disease symptoms.
"These findings and locomotion 'walking time' were reversed at high stimulation frequencies," he adds.
Although the result has been replicated in another patient, the researcher says that only further studies can determine the possible benefits of this approach for PD patients.
