Recognized Clinical Gait Pattern Types
The most clinically relevant gait patterns include: hemiplegic/circumductory gait, Parkinsonian gait, ataxic gait, steppage/drop foot gait, waddling gait, spastic gait, and functional gait disorders 1. These patterns represent distinct biomechanical and neurological presentations that guide diagnosis and treatment.
Primary Pathological Gait Patterns
Neurological Gait Patterns
Hemiplegic/Spastic Gait Patterns:
- Circumductory gait - the classic hemiplegic pattern where the affected leg swings outward in an arc during swing phase 2
- Drop foot pattern - inability to dorsiflex the ankle, causing toe-first contact 3
- Stiff knee during swing - reduced knee flexion preventing foot clearance 3
- Knee hyperextension during stance - excessive backward knee movement during weight-bearing 3
- Knee flexion in midstance - persistent knee bend during the standing phase 3
The hemiplegic patterns arise from combinations of muscle weakness, spasticity distribution, and compensatory reactions to ground forces 2. Assessment requires examining pelvic/hip movement first (which determines body vector and downstream compensations), then ankle/foot complex, then knee joint 2.
Parkinsonian Gait:
- Short-stepped, narrow-based, shuffling pattern 4
- Marked reduction of hip/knee range of motion with increased moment 5
- Reduced arm swing and forward-flexed posture 1
Ataxic Gait:
- Wide-based, unsteady pattern with irregular step timing 1
- Associated with cerebellar or sensory pathway dysfunction
Steppage Gait:
- High-stepping pattern to compensate for foot drop 1
- Hip and knee flexion exaggerated to clear the toes
Waddling Gait:
- Side-to-side trunk movement with each step 1
- Indicates proximal muscle weakness (hip abductors)
Additional Recognized Patterns
Dystonic Gait - involuntary muscle contractions causing twisted postures during walking 1
Choreiform Gait - irregular, dance-like movements interrupting normal gait 1
Stiff-Person Gait - rigid, board-like movement pattern 1
Functional Gait Disorders - inconsistent patterns that vary with attention and context, often with dramatic presentations 1
Multiple Sclerosis-Specific Patterns
In MS populations, consensus identifies six distinct patterns 3:
- Drop foot
- Insufficient push-off
- Stiff knee during swing
- Knee hyperextension during stance
- Knee flexion in midstance
- Enhanced gait variability
These patterns achieved 69% expert agreement on naming, characteristics, and underlying causes 3.
Clinical Subgroups Across Conditions
Three abnormal gait patterns emerge across multiple neurological and musculoskeletal conditions 5:
- Fast gait speed with adequate maximal hip extension
- Fast gait speed with inadequate maximal hip extension
- Slow gait speed
This classification system, based on gait speed and maximal hip extension angle, demonstrates high accuracy in predicting subgroups and can guide therapeutic approaches 5.
Key Clinical Considerations
Gait characteristics are significantly influenced by:
- Physical function and BMI 4
- Age and sex 4
- Disease-specific factors (e.g., Parkinson's produces short-stepped, narrow-based, shuffling gait) 4
Energy expenditure varies dramatically - hemiplegic patients may require up to 2 times the oxygen cost of walking compared to able-bodied persons, with mechanical efficiency markedly reduced 6. This creates a vicious cycle of decreased activity, reduced cardiorespiratory fitness, and further functional decline.
Assessment approach for spastic hemiplegic gait 2:
- First assess muscle strength and spasticity at hip, knee, and ankle/foot joints
- Examine pelvic and hip joint movement (determines body vector and compensatory reactions)
- Assess ankle and foot complex abnormality
- Examine knee joint abnormality
- Consider lidocaine nerve blocks as diagnostic tools to differentiate primary causes
The recognition of specific gait patterns is essential for targeting appropriate interventions, whether pharmacological (spasticity management), surgical (contracture release), or orthotic 7.
