Gait disorders in older adults
A healthy older adult's gait becomes slightly slower and more cautious, but a clear gait disorder is a sign of disease — and the pattern points to the cause: parkinsonian, frontal "magnetic", cerebellar ataxic, sensory ataxic, spastic, steppage or waddling; a gait speed below 0.8 m/s predicts falls, admission and death.
Why it matters in the exam
The exam describes a gait and asks for the diagnosis: small shuffling steps with reduced arm swing and turning "en bloc" — parkinsonism; wide steps that look "stuck to the floor" with difficulty starting — a frontal disorder (normal pressure hydrocephalus or vascular disease); a wide base and inability to walk heel-to-toe — cerebellum; a positive Romberg — sensory ataxia (B12 deficiency, neuropathy).
Recurring points: cervical stenosis with spinal cord damage (myelopathy) is common in older adults and presents with a spastic gait, clumsy hands and brisk reflexes — cervical MRI; lumbar canal stenosis causes leg pain on walking relieved by bending forward (the "shopping cart sign"); proximal weakness with a waddling gait points to myopathy (statins, steroids, thyroid); and fear of falling produces a "cautious gait" — slow and wide, with a normal neurological examination.
Treatment combines treating the cause, physiotherapy for strength and balance, a suitable walking aid and fewer sedating drugs. Simple clinic tests — gait speed, the Timed Up and Go and chair rise — help track improvement or decline.
Suitable shoes are part of treatment.
Key points
- A clear gait disorder in an older adult is a sign of disease.
- Gait speed below 0.8 m/s predicts falls and death.
- The gait pattern points to the cause: parkinsonian, frontal, cerebellar, sensory, spastic.
- Positive Romberg — B12 and neuropathy; spastic — cervical MRI.
- Treatment: the cause, physiotherapy, a walking aid, fewer sedating drugs.
Summary table
| Gait type | What is seen | Common causes |
|---|---|---|
| Parkinsonian | Small shuffling steps, less arm swing, en bloc turning, festination | Parkinson disease, neuroleptic drugs |
| Frontal ("magnetic") | Wide base, difficulty starting, "stuck to the floor" | Normal pressure hydrocephalus, vascular disease |
| Cerebellar ataxia | Wide base, cannot walk heel-to-toe | Alcohol, cerebellar stroke, drugs |
| Sensory ataxia | Positive Romberg, worse in the dark | B12 deficiency, diabetic neuropathy |
| Spastic | Stiff legs, brisk reflexes | Cervical myelopathy, stroke |
| Steppage / waddling | Foot drop / proximal weakness | Peroneal nerve injury / myopathy |
