Chronic Subdural Haematoma (SDH): Post-Burr Hole Neuro-Physiotherapy Guide
In short
Chronic subdural haematoma in older adults often masquerades as sudden dementia or stroke after a minor fall, requiring careful post-burr-hole neuro-rehabilitation.

The Insidious Onset of Chronic Subdural Haematoma in the Elderly
Chronic Subdural Haematoma (CSDH) is one of the most common neurosurgical conditions in the geriatric population. Due to age-related cerebral atrophy, the brain shrinks away from the dura mater, stretching the fragile bridging veins across the subdural space.
A trivial fall or sudden deceleration - often forgotten by the patient weeks earlier - shears these bridging veins. Slow, insidious venous bleeding accumulates over 3 to 6 weeks. When the expanding liquefied haematoma exceeds intracranial compensation, it presents as fluctuating confusion, hemiparesis, severe gait ataxia, or rapid cognitive decline.
Clinical Phases: From Burr Hole Evacuation to Independent Ambulation
| Postoperative Phase | Surgical Healing Status | Permitted Mobilisation Activities | Clinical Red Flags & Precautions | |
|---|---|---|---|---|
| Phase 1: Flat Bed Rest (Day 1-2) | Subdural drain in situ, brain re-expansion phase | Strict supine bed rest or flat position to encourage cortical re-expansion | Worsening headache, drain occlusion, acute drowsiness, pupillary changes | |
| Phase 2: Graduated Elevation (Day 3-5) | Drain removed, surgical burr-hole incision healing | High Fowler's sitting, bedside edge sitting, standing balance with support | Orthostatic dizziness, CSF rhinorrhea, focal motor seizure activity | |
| Phase 3: Assisted Walking (Week 2-3) | Subdural space stabilized, pneumocephalus resolving | Hallway ambulation with walker, gentle core stability, balance drills | Strict avoidance of vigorous head shaking, Valsalva straining, or bending forward | |
| Phase 4: Community Re-entry (Week 4-8) | Complete parenchymal healing, burr hole closure | Multicomponent balance, cognitive-motor dual tasking, fall prevention | Secondary fall prevention, anticoagulation monitoring |
Targeted Neuro-Rehabilitation Protocols for CSDH Patients
- Strict Avoidance of Inverted Head Positions: In the first 6 weeks post-evacuation, forbid activities where the head drops below the heart (e.g., deep bending, tying shoes) to prevent sudden spikes in venous intracranial pressure.
- Gentle Vestibular and Gaze Stabilization: Address persistent subjective unsteadiness with seated smooth pursuit and slow horizontal gaze shifting drills.
- Hemiparetic Symmetry Restoration: If the haematoma produced focal contralateral weakness, implement task-oriented upper limb reaching and weight-bearing through the paretic leg.
- Rigorous Secondary Fall Prevention: The single greatest danger to a post-burr-hole patient is experiencing another fall, which frequently causes fatal re-bleeding. Remove home hazards and mandate 24/7 gait aid usage.
- Blood Pressure Stability Monitoring: Avoid hypertensive surges during physiotherapy that could rupture fragile neomembrane vessels in the subdural space.
Frequently Asked Questions About Subdural Haematoma Rehabilitation
Why must my parent stay flat in bed for 24 to 48 hours after burr-hole surgery?
Neurosurgical protocols frequently keep the patient flat immediately after burr-hole evacuation to allow intracranial pressure to equalize and encourage the shrunken brain tissue to re-expand against the skull, filling the empty subdural space and preventing air entrapment (pneumocephalus).
Can an older adult make a full recovery after subdural haematoma surgery?
Yes. Burr hole evacuation of chronic SDH is one of the most rewarding procedures in neurosurgery. With prompt drainage followed by structured home neuro-physiotherapy, up to 80-90% of elderly patients regain their baseline functional independence.
