Study Notes
Pathological Gait in Neuro
- Neurological gait is used to identify clinical signs in various conditions.
- Specific conditions include stroke, Parkinson's Disease, Multiple Sclerosis, and peripheral nerve injury to the common peroneal nerve.
Gait in Stroke
- Initial Contact: Reduced heel strike due to decreased dorsiflexion and increased tone in extensor muscles. Absence of knee flexion or too much knee flexion.
- Loading Response: Reduced weight transfer onto the supporting leg. Patients struggle with lateral/forward weight transfer and may not trust the limb to provide support, leading to compensation with a short, quick step on the other leg.
- Mid-Stance: Reduced weight transfer leads to instability.
- Terminal Stance and Pre-Swing: Reduced forward propulsion due to reduced plantar flexion force. Results in a shorter step on the opposite side.
Reasons for Gait Issues (Stroke)
- Decreased motor control
- Muscle weakness
- Increased muscle tone (spasticity)
- Contractures or deformities
- Sensory deficits
- Balance problems
- Fear
Gait in Stroke: Swing Phase
- Decreased motor control of hip, knee, and ankle flexors coupled with increased tone in extensor muscles.
- Functional leg length discrepancy can result from these issues.
- Compensatory strategies include hip-hitching, circumduction, and vaulting.
Parkinson's Disease (PD)
-
Commonly Observed Problems:
- Flexion of trunk and hips
- Reduced trunk rotation and arm swing
- Shuffling steps with reduced heel strike and scuffing of foot during mid-swing.
- Short stride length, and increased double support.
- Freezing of gait (sudden or gradual inability to start or continue walking).
- Festination (involuntary progressive reduction in stride length, increasing cadence, and reduced walking speed).
- Difficulty turning (slow turns, more steps, poor foot clearance, pause before turning).
-
Reasons: Bradykinesia, rigidity, postural instability.
Multiple Sclerosis (MS)
-
Commonly observed problems:
- Flat foot on initial contact ("flapping foot").
- Irregular foot placement.
- Unpredictable step length.
- Wide-base or narrow-base/scissoring gait.
- Jerky movements.
- Midstance: knee hyper-extension from reduced eccentric quad activity
- Weight shifting forward, backward, and laterally, and potentially reliance on trunk for balance.
- Reasons: Fatigue, spasiticity, balance, proprioception, coordination, attentional demands, and potential weakness.
Peripheral Nerve Injury: Common Peroneal Nerve
-
Clinical presentation:
- Motor loss, including flaccid paralysis.
- Sensory loss (diagram of nerve, location of motor and sensory loss).
Commonly Observed Problems (Peripheral Nerve Injury)
-
Foot that drops (unable to hold foot up).
-
"Slapping" gait.
-
Toes drag while walking.
-
High stepping gait.
-
Functional leg length discrepancy (requires compensation).
-
Reasons: Loss of muscle control in lower legs/feet, atrophy of foot/lower leg muscles, decreased sensation (numbness/tingling).
