Post-Stroke Gait Training Protocol

Introduction

This protocol outlines a comprehensive gait training program for individuals recovering from stroke. The goal is to maximize functional mobility, improve gait speed, endurance, and symmetry, and minimize compensatory strategies. This protocol is a guideline and should be individualized based on patient presentation, medical history, and response to treatment. Safety is paramount; frequent monitoring and appropriate assistive devices are essential.

Clinical Presentation

Stroke survivors often present with a variety of gait impairments, including:

• Hemiparesis or hemiplegia
• Reduced balance and coordination
• Decreased gait speed and endurance
• Asymmetrical gait pattern (e.g., circumduction, hip hiking, equinus gait)
• Increased risk of falls
• Sensory deficits affecting proprioception
• Cognitive impairments impacting motor learning

Rehabilitation Phases

Gait training progresses through distinct phases, adapting to the patient's evolving abilities:

Phase 1: Pre-Gait Training (Bedside/Mat Activities)

Focuses on foundational skills for gait. Improves strength, range of motion, and balance in a supported environment.

Phase 2: Initial Gait Training (Supported Standing/Partial Weight Bearing)

Introduces upright posture and weight bearing in a controlled environment. Emphasis on proper alignment and controlled movement.

Phase 3: Progressive Gait Training (Full Weight Bearing/Overground Walking)

Focuses on improving gait speed, endurance, and symmetry. Gradually reduces support and increases distance.

Phase 4: Advanced Gait Training (Community Ambulation/Complex Environments)

Challenges the patient in real-world settings. Addresses obstacles, uneven surfaces, and varying speeds.

Exercise Examples (Progressing Through Phases)

1. Ankle Pumps (Phase 1): Dorsiflexion and plantarflexion exercises to improve circulation and ankle range of motion. Rationale: Increases blood flow and prevents contractures.
2. Heel Slides (Phase 1): Supine or seated, patient slides heel towards buttocks, promoting hip and knee flexion. Rationale: Improves lower extremity range of motion and prepares for weight shifting.
3. Bridging (Phase 1): Patient lifts hips off the floor, engaging gluteal and hamstring muscles. Rationale: Strengthens hip extensors for push-off during gait.
4. Sit-to-Stand Transfers (Phase 2): Practicing controlled transitions from sitting to standing with appropriate assistance. Rationale: Builds strength and control for upright posture.
5. Weight Shifting (Phase 2): Standing with support, patient shifts weight from side to side and forward to back. Rationale: Improves balance and weight-bearing capacity.
6. Parallel Bar Stepping (Phase 2): Short steps forward and backward within parallel bars, focusing on equal weight bearing and controlled movements. Rationale: Improves step length and coordination.
7. Assisted Walking with Assistive Device (Phase 3): Using a walker or cane, patient practices walking overground, focusing on heel-toe progression and symmetrical steps. Rationale: Improves gait speed, distance, and symmetry.
8. Cadence Training (Phase 3): Using a metronome to regulate step frequency and improve rhythm. Rationale: Improves gait efficiency and reduces energy expenditure.
9. Step-Ups (Phase 3): Progressing from low to higher steps, focusing on controlled ascent and descent. Rationale: Improves lower extremity strength and stability.
10. Balance Training with Perturbations (Phase 4): Practicing maintaining balance while subjected to external disturbances (e.g., gentle pushes, uneven surfaces). Rationale: Improves dynamic balance and reduces fall risk.
11. Stair Climbing (Phase 4): Ascending and descending stairs with appropriate handrail support. Rationale: Improves functional mobility and strengthens lower extremities.
12. Dual-Task Training (Phase 4): Walking while performing a cognitive task (e.g., counting backwards, carrying an object). Rationale: Improves attention and reduces fall risk in complex environments.

Evidence-Based Return to Function Criteria

Progression to each phase and ultimate discharge should be based on the following criteria:

• Gait Speed: Achieving a minimum gait speed of 0.4 m/s is associated with household ambulation; 0.8 m/s for limited community ambulation; and 1.2 m/s for independent community ambulation (Perry, J. Gait Analysis: Normal and Pathological Function).
• Endurance: Ability to walk for at least 10 minutes continuously without significant fatigue or increased spasticity.
• Balance: Successful completion of standardized balance tests (e.g., Berg Balance Scale, Timed Up and Go) with scores indicating low fall risk.
• Symmetry: Reduced asymmetry in step length, stride length, and weight-bearing time. Objective measures such as instrumented gait analysis can be used.
• Independence: Ability to ambulate safely and independently in desired environments, with or without assistive devices.
• Functional Goals: Achievement of patient-specific functional goals (e.g., returning to work, participating in recreational activities).
