Gait Analysis and Gait Training

Gait analysis is the systematic measurement and description of walking, and gait training is the re-education of walking after injury or disease. Together they let physiotherapists characterise how a person walks, identify deviations from typical patterns, and frame the practice of walking as a learnable motor skill.

Definition

Gait analysis is the quantitative and qualitative assessment of the gait cycle using spatiotemporal, kinematic, and kinetic measures; gait training is the structured practice and re-education of walking aimed at improving its quality, efficiency, and safety.

Scope

This topic covers the structure of the gait cycle, the spatiotemporal and kinematic and kinetic parameters used to describe walking, the main methods of observational and instrumented gait analysis, and the rationale for task-specific gait training. It is a reference-educational overview of how walking is measured and re-trained, not a guide to selecting interventions for an individual.

Core questions

• How is the gait cycle structured, and which parameters best describe normal and pathological walking?
• What do observational and instrumented gait analysis each add, and what are their limits?
• On what principles is task-specific gait training based?

Key concepts

• Gait cycle (stance and swing phases)
• Spatiotemporal parameters (cadence, step length, walking speed)
• Kinematics and kinetics of walking
• Observational gait analysis
• Instrumented (three-dimensional) gait analysis
• Dynamic balance during walking
• Task-specific gait training

Mechanisms

Walking is described as a repeating gait cycle divided into stance and swing phases, with each limb alternating support and progression. Gait analysis quantifies this cycle through spatiotemporal parameters (such as speed, cadence, and step length), joint kinematics, and ground-reaction-force kinetics, typically measured with motion-capture systems, force plates, and electromyography in instrumented laboratories, or estimated by trained observation (Baker 2006; Perry 2010). Maintaining balance while walking is itself an active control problem, because the body's centre of mass passes outside the base of support during each step and must be managed by foot placement and trunk control (Winter 1995). Gait training applies motor-learning principles to walking as a task, using repetition, feedback, and progressive challenge to re-educate the pattern (Shumway-Cook 2017).

Clinical relevance

Gait analysis gives physiotherapists an objective and shared language for describing walking and for tracking change, while gait training frames walking as a skill that can be re-learned. The topic explains how walking is measured and conceptualised as a basis for evidence appraisal; it does not prescribe specific assessments, devices, or training programmes for an individual.

Evidence & guidelines

The topic draws on biomechanics and rehabilitation methodology rather than a single guideline. Methodological reviews (Baker 2006), biomechanical analyses of balance in walking (Winter 1995), and standard reference texts (Perry & Burnfield 2010; Shumway-Cook & Woollacott 2017) provide the conventional framing of gait measurement and re-education.

History

Descriptive study of human walking dates to nineteenth-century photographic motion studies, but clinical gait analysis matured with the development of biomechanical instrumentation in the later twentieth century. Jacquelin Perry's work systematised the clinical description of the gait cycle, and David Winter's biomechanical analyses established many of the quantitative methods still used to study walking and balance.

Debates

How much does instrumented gait analysis add over observation?

Three-dimensional gait analysis yields precise, reproducible data but is resource-intensive and not universally available, so its incremental value over careful observational analysis in routine practice remains a methodological discussion.

Frequently asked questions

What is the gait cycle?

The gait cycle is one complete sequence of walking for a single limb, from initial contact of one foot to the next contact of the same foot. It is divided into a stance phase, when the foot is on the ground, and a swing phase, when the limb advances.

What is the difference between observational and instrumented gait analysis?

Observational gait analysis relies on a trained clinician watching and describing walking, often aided by video. Instrumented gait analysis uses motion-capture cameras, force plates, and other sensors to measure kinematics and kinetics quantitatively, giving more precise but more resource-intensive data.
