Description
Estimated cost for Functional Electrical Stimulation at general public hospitals in China is about ¥140-640, and at Grade 3A hospitals about ¥200-800, varying by hospital tier and region.
Main Uses
Primary clinical uses include: restoring functional motor tasks (e.g., hand grasp, standing, stepping, cycling) in individuals with spinal cord injury, stroke, multiple sclerosis, or traumatic brain injury; preventing disuse atrophy and orthopedic complications (e.g., contractures, osteoporosis); improving circulation and reducing edema; enhancing neuroplasticity through activity-dependent cortical reorganization; and supporting rehabilitation goals such as gait training, upper-limb recovery, and bladder/bowel control via targeted stimulation.
Normal Range
Functional Electrical Stimulation (FES) is not a diagnostic laboratory test with numerical 'values' or a defined 'normal range'. It is a therapeutic neuromodulation technique involving the application of low-energy electrical pulses to activate paralyzed or weakened muscles. Parameters such as pulse amplitude (typically 0–120 mA), pulse width (50–400 µs), frequency (1–50 Hz), and on/off timing are individually titrated based on patient tolerance, muscle response, and functional goals—not standardized population-based reference ranges.
Low Values - Possible Causes
Low or absent muscle response during FES may result from: 1) Severe peripheral nerve damage or denervation, 2) Advanced muscle atrophy or fibrosis, 3) Electrode misplacement or poor skin-electrode contact, 4) Inadequate stimulation intensity due to pain intolerance or safety limits, 5) Central nervous system lesions disrupting corticospinal drive necessary for synergistic FES-assisted movement.
High Values - Possible Causes
Excessively strong or adverse responses during FES may arise from: 1) Overstimulation due to incorrect parameter settings (e.g., excessive amplitude or frequency), 2) Hyperexcitable neural tissue (e.g., spasticity post-stroke or spinal cord injury), 3) Undiagnosed peripheral nerve hypersensitivity or neuropathic pain syndromes, 4) Electrode proximity to sensory nerves causing uncomfortable or painful sensations, 5) Inadequate habituation or insufficient ramp-up protocol in treatment-naïve patients.
