Peripheral neuropathy , for example, involves damage to the peripheral nerves, leading to numbness, tingling, and a "foot drop" gait where the toes drag during the swing phase. Conditions affecting the brain itself, such as stroke or cerebral palsy, may result in hemiplegia (paralysis on one side) or dysmetria (inability to control the distance, power, and speed of a muscular action), both of which severely alter gait mechanics.
Neurological Causes and Terminology of Gait Abnormality
A physician will observe the walking pattern, assessing for features like symmetry, arm swing, and stability during turns. Dyskinesia refers to involuntary, erratic movements that disrupt smooth locomotion, while bradykinesia indicates a significant slowness of movement, commonly seen in Parkinson's disease.
This impairment can manifest as weakness, imbalance, pain, or a change in the rhythm and pattern of walking, often serving as a critical indicator of underlying neurological, musculoskeletal, or systemic disease. " Terms like ataxia describe a lack of muscle coordination leading to a staggering, wide-based walk, often linked to cerebellar dysfunction.

Diagnostic Evaluation and Clinical Assessment Diagnosing the root cause of a gait disturbance involves a systematic approach that combines patient history with physical examination. Arthritis in weight-bearing joints like the hips or knees causes pain that alters stride length and frequency, while tendinopathy or bursitis can create localized pain that inhibits normal movement.
