Summary
Motor cortex stimulation (MCS) offers a minimally invasive surgical option for Parkinson's disease (PD). This neuromodulation technique shows significant benefits for motor symptoms, axial symptoms, and quality of life in advanced PD patients.
Area of Science:
- Neurosurgery
- Neuromodulation
- Movement Disorders
Background:
- Parkinson's disease (PD) is a progressive neurodegenerative disorder.
- Advanced PD often presents challenges with existing therapies.
- Minimally invasive neuromodulation is being explored as a therapeutic option.
Purpose of the Study:
- To review the efficacy and safety of motor cortex stimulation (MCS) in advanced Parkinson's disease.
- To assess MCS as a potential alternative to deep brain stimulation (DBS).
Main Methods:
- Systematic review of 16 published articles.
- Inclusion of 130 patients with advanced Parkinson's disease.
- Analysis of surgical techniques, stimulation parameters, and outcomes.
Main Results:
- Thirteen studies reported significant improvements in motor symptoms, axial symptoms, L-dopa-induced dyskinesia, and quality of life.
- Extradural MCS showed a lower rate of complications compared to subdural MCS.
- Negative results were reported in three studies.
Conclusions:
- Extra/intradural MCS is a viable, minimally invasive surgical alternative for PD patients unsuitable for DBS.
- MCS demonstrates significant effectiveness on axial symptoms, gait disturbances, and therapy complications.
- The procedure has low morbidity and mortality, offering bilateral symptom relief.

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...
