Recovery following complete paraplegia

Area of Science:

• Neurology
• Rehabilitation Medicine
• Spinal Cord Injury Research

Background:

• Paraplegia, resulting from spinal cord injury (SCI), presents significant challenges in motor and sensory function.
• Understanding factors influencing recovery is crucial for patient prognosis and therapeutic strategies.

Purpose of the Study:

• To prospectively quantify motor and sensory recovery in individuals with paraplegia.
• To determine the relationship between the initial neurologic level of injury (NLI) and functional outcomes.

Main Methods:

• Serial examinations were conducted on 148 individuals with paraplegia.
• Motor and sensory function assessments were performed to track recovery.
• Patients were categorized based on their initial neurologic level of injury (NLI).

Main Results:

• No patients with an initial NLI above T9 regained lower extremity motor function.
• 38% of patients with an initial NLI at or below T9 experienced some motor function return, mainly in hip flexors and knee extensors.
• 20% of patients with an initial NLI at or below T12 achieved ambulation with assistive devices.
• Sensory recovery (light touch, sharp-dull discrimination) was independent of the initial NLI.
• Late conversion ( >4 months) from complete to incomplete SCI occurred in 6% of patients, with some achieving ambulation or bladder/bowel control.

Conclusions:

• The initial neurologic level of injury is a significant predictor of motor recovery in paraplegia.
• Lower injury levels (at or below T9) are associated with a higher likelihood of motor function return and potential ambulation.
• Late conversion to incomplete SCI status can lead to meaningful functional gains, including ambulation and improved autonomic function.
