The Aminoff-Logue Disability Scale (ALD) is used to assess disability related to gait disturbance and bladder function in individuals with spinal dural arteriovenous fistula (dAVF). This scale helps clinicians evaluate the severity of symptoms and predict the likelihood of improvement based on the total score.

Components of the Scale:

Gait Disturbance:

0: None

1: Leg weakness or abnormal gait, activity not restricted

2: Leg weakness or abnormal gait, activity restricted

3: Requires 1 stick (cane) for walking

4: Requires 2 sticks (canes) for walking

5: Unable to stand, confined to bed/wheelchair

Micturition (Bladder Function):

0: Normal

1: Hesitancy, frequency, urgency

2: Occasional urinary incontinence or retention

3: Total urinary incontinence or retention

Interpretation of Scores:

ALD Score 0–3: Indicates a 78% chance of substantial improvement.

ALD Score 4–5: Suggests a 29% chance of substantial improvement.

ALD Score 6–8: Predicts an 11% chance of substantial improvement.

Clinical Implications:

Patients with lower ALD scores (0–3) are more likely to experience significant improvement in their symptoms.

Higher ALD scores (4–8) indicate a lower likelihood of substantial improvement, suggesting a more severe disability.

Clinicians can use the ALD scale to assess baseline disability, monitor progression, and guide treatment decisions for individuals with spinal dAVF.

Regular evaluation using the ALD scale allows healthcare providers to tailor interventions and optimize outcomes for patients with spinal dural arteriovenous fistula.
