Introduction
Anterior Cord Syndrome (ACS) is an incomplete spinal cord injury characterized by damage to the anterior two-thirds of the spinal cord. It commonly results from trauma or vascular compromise and remarkably affects motor and sensory functions, making early recognition and rehabilitation essential.
Definition
Anterior Cord Syndrome is defined as a neurological condition involving impairment of motor function, pain, and temperature sensation below the level of injury, while preserving posterior column functions such as proprioception, vibration, and light touch.
Etiology
- Traumatic causes: Flexion injuries, burst fractures, or dislocations of the vertebrae
- Vascular causes: Anterior spinal artery occlusion or ischemia
- Infections or tumors affecting the anterior spinal cord region
- Post-surgical complications following spinal procedures
- Disc herniation compressing the anterior cord
Clinical Features
- Motor paralysis below the level of injury (complete or partial)
- Loss of pain and temperature sensation due to spinothalamic tract involvement
- Preserved proprioception and vibration sense (dorsal columns intact)
- Autonomic dysfunction: bladder, bowel, and sexual impairment
- Variable recovery, often poorer compared to other incomplete cord syndromes
Complications
- Chronic paralysis and functional dependency
- Respiratory complications
- Pressure ulcers due to immobility
- Urinary tract infections and bowel dysfunction
- Deep vein thrombosis (DVT)
- Spasticity and neuropathic pain
Physiotherapy Management
- Early mobilization to prevent complications and promote circulation
- Electrotherapy (e.g., FES) to stimulate muscle activity
- Positioning and splinting to avoid contractures and pressure sores
- Strengthening exercises for preserved muscles
- Gait training using assistive devices
- Respiratory physiotherapy for patients with high spinal involvement
- Patient and caregiver education on skin care and home management
Conclusion
Anterior Cord Syndrome is a serious neurological condition with remarkable motor impairment and limited recovery potential. Early diagnosis, multidisciplinary care, and structured physiotherapy rehabilitation are vital in maximizing functional independence and improving quality of life.
Q: What is Anterior Cord Syndrome (ACS)?
A: It is an incomplete spinal cord injury affecting the anterior two-thirds, causing motor loss and impaired pain and temperature sensation.
Q: Which sensations are preserved in ACS?
A: Proprioception, vibration, and light touch are preserved due to intact dorsal columns.
Q: What is a key goal of physiotherapy in ACS?
A: To improve mobility and prevent complications through early mobilization and strengthening exercises.
