A runner may report calf tightness, knee symptoms, hip discomfort or reduced running efficiency, but a single strength or ROM test may not show how they actually move while running.
A lateral-view running gait analysis provides a side-view snapshot of running strategy. It can help professionals observe sagittal-plane features such as trunk position, step length, foot strike position, knee flexion, hip extension, vertical motion and arm swing.
The result should be interpreted as movement observation, not as a diagnosis or proof of injury risk.
Test name: Running Gait Analysis (Lateral)
Also known as: Lateral Running Gait Checklist, Side-View Running Analysis, Sagittal-Plane Running Assessment
Purpose: Observe running movement from the side
What it assesses: Sagittal-plane running strategy, trunk position, foot strike, step length, knee flexion, hip extension, vertical motion and arm swing
Equipment required: Smartphone or camera, tripod, treadmill or repeatable running path, Measurz recording system
Key finding: Observed movement features, symptoms, speed, footwear, surface and changes over time
Best used with: Running history, symptoms, training load, strength testing, ROM testing, balance tests and posterior/frontal-view running analysis
Key limitation: Lateral analysis cannot diagnose injury, measure exact joint loading or capture frontal/transverse-plane mechanics on its own
Running Gait Analysis (Lateral) is a side-view observation of a runner.
The camera is positioned perpendicular to the runner, allowing the professional to observe sagittal-plane movement features.
Common observations include:
trunk lean
head and neck position
arm swing
hip extension
knee flexion at stance and swing
foot strike position relative to the body
tibial angle at contact
step length
vertical motion
stride rhythm
fatigue-related changes
It may be completed on a treadmill or along a flat running path, as long as setup details are recorded.
Lateral running gait analysis is used to observe how a runner moves in a repeatable and practical way.
It can help professionals:
document running strategy
compare baseline and retest videos
observe symptom-linked movement changes
identify whether related strength or mobility tests may add context
support running technique discussions
monitor return-to-running progressions
observe fatigue-related changes
compare footwear or speed conditions cautiously
It is useful because many running features are easiest to observe from the side.
Lateral running gait analysis does not measure one isolated physical quality.
It may provide insight into:
sagittal-plane trunk position
foot strike position relative to the body
step length
tibial inclination
knee flexion strategy
hip extension
vertical motion
cadence estimate
arm swing timing
fatigue-related changes
symptom response during running
It does not directly measure:
diagnosis
tissue damage
injury risk with certainty
ground reaction forces
exact joint loading
3D hip or knee mechanics
foot pronation from the rear view
pelvic drop from the rear view
strength or mobility
readiness to return to running
A lateral gait video should be interpreted as part of a broader assessment.
Running Gait Analysis (Lateral) may be useful for:
runners
triathletes
field sport athletes
court sport athletes
return-to-running clients
running coaches
strength and conditioning coaches
health and fitness professionals
rehabilitation professionals
professionals monitoring running technique over time
It may be useful for runners with:
running-related symptoms
training load changes
calf or Achilles symptoms
knee symptoms
hip symptoms
low back symptoms
recurrent flare-ups
performance goals
interest in running technique feedback
You will need:
smartphone or camera
tripod or stable camera mount
treadmill or flat running area
consistent lighting
Measurz or MAT recording system
running shoes normally used by the client
Optional equipment:
frame-rate settings suitable for movement review
markers on treadmill or floor
metronome if cadence is being standardised
heart rate monitor
RPE scale
pain scale
posterior or anterior camera view for additional context
Record the running context
Record recent training load, running symptoms, footwear, surface, speed, incline, fatigue, warm-up and purpose of the assessment.
Choose the running setup
Use either a treadmill or a repeatable flat running path. Keep the setup consistent for retesting.
Position the camera
Place the camera side-on to the runner, roughly perpendicular to the direction of running.
Set camera height
Position the camera around hip height where possible. Keep the runner fully visible from head to foot.
Standardise distance
Use the same camera distance each time. Avoid excessive zoom changes between sessions.
Record enough strides
Record enough running to observe several consistent stride cycles. Avoid interpreting one isolated step.
Record both sides if needed
If the runner is on a treadmill, one side may be captured at a time. If asymmetry is suspected, record both left and right lateral views if possible.
Observe key features
Review trunk position, foot strike, tibial angle, step length, knee flexion, hip extension, vertical motion and arm swing.
Record symptoms
Ask about pain, stiffness, fatigue, confidence and whether symptoms changed during the run.
Compare with related tests
Interpret findings with strength, ROM, training load, footwear, surface and symptom history.
Running gait analysis is usually scored using structured observations rather than a single numerical score.
Common recording options include:
checklist items
qualitative movement notes
symptom response
video comparison
cadence estimate
running speed
footwear
surface
fatigue stage
confidence
change over time
Interpretation should include:
what was observed
when it occurred
whether it was consistent
whether it was linked to symptoms
whether it changed with speed or fatigue
whether related tests support the finding
A lateral-view observation should not be described as the cause of pain on its own.
Safer wording includes:
“This may be contributing to loading strategy.”
“This is worth monitoring across sessions.”
“This observation may guide related strength or mobility testing.”
“This pattern changed when speed increased.”
“This does not diagnose the cause of symptoms by itself.”
There are no universal norms for lateral running gait analysis that apply to every runner.
Running movement varies by:
speed
footwear
surface
training background
fatigue
body size
injury history
slope
treadmill versus overground running
running goals
camera setup
For most Measurz use, interpretation should focus on:
baseline video
repeat video under the same conditions
symptoms
speed
cadence
step length
related strength and ROM findings
training load
client goals
Some research and teaching resources discuss specific running features, but these should be treated as context rather than universal pass/fail criteria.
Two-dimensional running gait analysis can be useful when video setup is consistent and interpretation is cautious.
Reliability improves when:
the same camera position is used
camera height is standardised
speed is recorded
footwear is recorded
treadmill or surface is consistent
multiple strides are reviewed
the same checklist is used
symptoms are recorded
fatigue stage is recorded
the same professional or scoring method is used where possible
Lateral view is most useful for sagittal-plane observations. It is less useful for frontal-plane or transverse-plane features such as pelvic drop, knee valgus, foot pronation or trunk rotation.
A recent camera-view analysis reported that lateral views were more useful for sagittal-plane kinematic features, while frontal views were better for some symmetry measures. This supports using lateral and posterior/frontal views together where possible, rather than relying on one view alone.
Sensitivity and specificity are not usually applicable for routine Measurz use of Running Gait Analysis (Lateral).
This is an observational movement assessment, not a stand-alone diagnostic or screening test.
It can support running assessment and progress tracking, but it should not be used by itself to diagnose an injury, predict future injury, classify readiness or determine whether a runner can return to training.
Common errors include:
using only one stride for interpretation
changing camera angle between sessions
changing speed without recording it
comparing treadmill and outdoor running directly
not recording footwear
not recording symptoms
making diagnostic claims from video alone
ignoring fatigue
over-interpreting small movement differences
using lateral view to judge frontal-plane mechanics
failing to pair video findings with strength and ROM tests
Key limitations include:
two-dimensional video cannot fully capture 3D movement
camera angle affects what is seen
treadmill running may differ from outdoor running
speed changes movement strategy
fatigue changes movement strategy
symptoms can alter running form
observation does not measure exact joint load
checklist findings are not diagnoses
Use Running Gait Analysis (Lateral) to:
document baseline running strategy
monitor technique changes over time
observe running under different speeds
compare early and fatigued running
guide strength or mobility follow-up tests
support return-to-running progressions
discuss running cues cautiously
track symptoms during running
It is most useful when combined with:
posterior or anterior running view
running history
training load
pain and symptom notes
ankle dorsiflexion testing
calf raise endurance
hip strength testing
single-leg balance
hop testing
gait speed or time trials
cadence or GPS data
In Measurz, record:
view used: lateral
side recorded
treadmill or overground
speed
incline
surface
footwear
warm-up
fatigue stage
pain score
symptom location
cadence if available
observed trunk position
foot strike position
step length notes
knee flexion notes
hip extension notes
vertical motion notes
arm swing notes
related strength or ROM findings
retest date
Example note:
“Running Gait Analysis – Lateral. Treadmill, 10 km/h, 0% incline, usual shoes, after 5 min warm-up. Right lateral view recorded. Observed mild overstride at initial contact, moderate vertical motion and reduced hip extension late in run. No pain during recording. Compare with calf raise endurance, ankle dorsiflexion and repeat video in same setup.”

It assesses side-view running movement, especially sagittal-plane features such as trunk position, step length, foot strike, knee flexion and hip extension.
No. It can support assessment and progress tracking, but it does not diagnose injury causes on its own.
Either can be used, but the setup should be recorded and repeated consistently. Treadmill and outdoor results should not be compared directly without caution.
Review several consistent stride cycles rather than one isolated step.
Yes. Running speed strongly affects gait, so speed should always be recorded.
Usually not. Lateral view is useful for sagittal-plane features, but posterior or anterior views add information about frontal-plane movement.
Yes. Pain, fatigue, stiffness and confidence change interpretation.
Lateral running gait analysis gives a side-view snapshot of running strategy.
It is useful for sagittal-plane observations such as trunk position, step length, foot strike, knee flexion and hip extension.
It should not be used to diagnose injury or prove injury risk.
Speed, footwear, surface, fatigue and symptoms must be recorded.
Lateral and posterior/frontal views are best used together when possible.
Measurz should capture setup, observations, symptoms, related tests and retest context.
