Gait analysis is the assessment of how you walk or run, examining the pattern, timing and mechanics of each step. It sounds simple, but the way your body moves through a single stride involves a coordinated sequence across the foot, ankle, knee, hip and spine, and small deviations in that sequence are frequently the real explanation behind pain that otherwise seems to come from nowhere.
This guide explains what a gait analysis actually involves, when it is genuinely useful, and what technology such as motion tracking adds over watching someone walk.
Why gait matters beyond the obvious
An awkward-looking walk is not the main reason gait analysis is useful. The more common scenario is someone with an efficient-looking, unremarkable gait who nonetheless has recurring knee pain, shin splints, or hip discomfort that will not resolve.
The explanation is often a small mechanical deviation, repeated thousands of times over a run or a working day, that the eye alone struggles to catch. A knee drifting slightly inward on landing, a foot overpronating, asymmetrical hip drop, reduced ankle mobility on one side. None of these are dramatic in isolation. Repeated for miles, or for years of daily walking, they add up.
What a gait analysis assessment involves
History and goals
What you are trying to solve. Recurring pain, preparing for an event, general movement efficiency, or recovery after injury or surgery all lead to a different assessment focus.
Static assessment
Standing posture, joint alignment, muscle length and basic strength testing, providing context before movement is observed.
Dynamic assessment
Watching, and increasingly recording, how you actually move. This might be walking or running on a treadmill, or, for some assessments, movement patterns such as a squat or a step-down that reveal similar mechanical issues without needing a track.
Analysis
Where technology adds genuine value. Motion capture systems can measure joint angles, timing and symmetry with a precision the eye cannot match, and can slow footage down to examine a single phase of the stride in detail.
Recommendations
A useful assessment ends with something practical: specific exercises, movement retraining cues, footwear guidance, or a referral for further treatment if the findings point to it.
What technology adds over a visual assessment
Watching someone walk gives a trained eye a great deal of information. What it cannot easily do is quantify.
Motion tracking technology can measure the actual degree of knee valgus, the precise timing asymmetry between left and right, or the exact percentage of weight shifted to one side during a movement. This turns an impression, such as an observation that the left knee seems to move inward, into a number that can be tracked over time.
That matters for two reasons. First, it allows a baseline to be set and re-tested later, showing whether an intervention is actually changing the pattern rather than just assuming it has. Second, small deviations that are genuinely difficult to see at normal speed become measurable and repeatable rather than a matter of opinion.
Who benefits from gait analysis
- Runners with recurring injuries such as shin splints, runners knee, plantar fasciitis or IT band pain that keeps returning despite rest
- People starting or increasing running who want to establish good mechanics before problems develop
- Anyone with unexplained joint pain in the knee, hip or lower back that has not responded to general treatment
- Post-injury or post-surgical rehabilitation, where movement patterns often compensate around an old injury even after it has technically healed
- People choosing new running shoes or considering orthotics, where understanding actual foot mechanics beats guessing
- Older adults with balance or fall concerns, where gait changes can be an early indicator worth catching
Common findings, and why they matter
Overpronation
Excessive inward rolling of the foot after landing. Some pronation is normal and necessary for shock absorption; the question is degree and timing, not whether it happens at all.
Knee valgus
The knee drifting inward during landing or single-leg loading, often linked to hip and glute strength rather than the knee itself, which is why hip strengthening frequently forms part of the correction rather than anything done directly to the knee.
Asymmetry
Differences between left and right sides in timing, loading or range of motion, often the residue of a previous injury the body has quietly compensated around.
Reduced hip extension
Common with prolonged sitting, and it changes stride mechanics further down the chain, frequently showing up as knee or lower back symptoms rather than hip symptoms.
What happens after the assessment
Findings from a gait analysis are typically addressed through:
- Targeted strengthening for the specific weakness identified, most often around the hip and glutes
- Movement retraining, using cues and feedback to consciously adjust a pattern, sometimes with real time visual feedback during retraining
- Mobility work where restricted range is contributing to compensation elsewhere
- Footwear or orthotic guidance, based on actual mechanics rather than guesswork
- A graded return to training, where load is adjusted while new patterns are still developing
Gait patterns rarely change from advice alone. They change through consistent strength and movement work over a period of weeks, ideally reviewed and adjusted along the way rather than corrected once and left alone.
Should everyone get a gait analysis?
Not necessarily. If you run regularly without pain, formal analysis is not essential, though many find it useful preventatively. It is most valuable when there is a specific problem to solve: recurring injury, unexplained pain, or a genuine question about footwear or technique. Analysis for its own sake, without a question attached, tends to generate information without a clear next step.
Frequently asked questions
Do I need to be a runner to benefit?
No. Walking gait analysis is relevant for general movement problems, older adults with balance concerns, and anyone with unexplained lower body pain.
How long does an assessment take?
Typically 45 to 60 minutes including history, static assessment, dynamic recording and initial recommendations.
Will I need new shoes afterwards?
Sometimes, but not always. Footwear is one variable among several, and mechanical findings often point toward strengthening or movement work rather than footwear alone.
Can gait analysis prevent injury?
It can identify risk factors and address them before they cause a problem, though it cannot guarantee prevention, since injury has multiple contributing causes.
Is it painful?
No. It involves observation and movement, not treatment, though it may include some strength testing.
Gait analysis in Chiswick
Gait analysis is offered at Omnia Lifestyle in Chiswick, W4, using Pixformance motion tracking alongside physiotherapy assessment, close to Gunnersbury station. Findings are translated into a specific plan rather than left as observations alone.
