Gait Abnormalities in the Elderly: Causes and Treatment
Changes in walking pattern (gait abnormalities) are common in older adults and are a significant cause of falls and reduced mobility. The characteristic "elderly gait" — slower, shorter steps, wider base of support, reduced arm swing, and a more cautious pattern — is not simply a normal part of ageing but often indicates underlying problems that can be addressed.
The causes of gait abnormalities in older adults are diverse. Muscle weakness, particularly in the quadriceps and hip abductors, causes shortened steps and a Trendelenburg pattern (the trunk sways side to side). Joint problems — arthritis, stiffness, or pain — alter gait to avoid loading the affected joint. Balance impairment leads to a cautious gait with wider base and shorter steps. Neurological conditions cause specific gait patterns: Parkinson's produces a shuffling, festinating gait; stroke causes a hemiplegic gait with circumduction (swinging the leg outward); cerebellar problems cause an ataxic (uncoordinated) gait.
Sensory changes also affect gait. Reduced proprioception (awareness of joint position), common in diabetes and peripheral neuropathy, leads to a stamping gait as patients rely on tactile feedback. Vision impairment causes a cautious, slow gait. Vestibular (inner ear) problems cause unsteadiness and veering.
Fear of falling creates a self-reinforcing cycle: the cautious gait adopted to avoid falls actually increases fall risk by reducing the dynamic balance that comes from normal walking. Medications, particularly sedatives and blood pressure medications, can cause dizziness and unsteadiness that affect gait.
Treatment requires identifying the specific cause through comprehensive assessment. Strength training addresses weakness. Balance training improves stability. Gait retraining corrects compensatory patterns. Manual therapy and exercise address joint problems. Neurological rehabilitation treats condition-specific gait disorders. Medication review may identify contributing drugs.
Our elderly physiotherapy service provides comprehensive gait assessment and rehabilitation. Our falls prevention programme addresses the fall risk associated with gait abnormalities. For patients with neurological gait disorders, our neurological physiotherapy and stroke rehabilitation services provide specialist treatment.
