The Ankle Toe Flexion Strength Test measures isometric force output during toe flexion, usually across the lesser toes or multiple toes depending on the setup. The client pushes the toes downward into a Muscle Meter, handheld dynamometer, toe plate or fixed setup while the professional controls foot position and records force. When used on its own, the Muscle Meter primarily measures peak force. When used with Measurz, additional force-time metrics may be recorded or analysed depending on the setup, protocol and data quality. The result should be interpreted alongside symptoms, toe range of motion, foot posture, gait, balance, footwear, sport or work demands, baseline comparison and repeated testing.
Toe flexion strength helps support foot stability, balance, walking, running, push-off, forefoot loading and control of the foot during stance.
Toe flexion may involve:
flexor digitorum longus
flexor digitorum brevis
lumbricals
interossei
quadratus plantae
intrinsic foot muscles
coordinated ankle and forefoot control
A Muscle Meter or handheld dynamometer can help quantify toe flexion force rather than relying only on visual observation, toe gripping appearance or manual resistance. This makes baseline testing, side-to-side comparison and progress tracking more objective.
Toe flexor strength can be measured using different methods. Research comparing seated toe flexion dynamometry with standing pressure-mat tests found that seated dynamometry may better isolate the toe flexors, while standing pressure-mat tasks may be more functional for some presentations. The two approaches were related but not identical, which reinforces the need to record the exact method used.
The test does not diagnose plantar fascia pain, metatarsalgia, plantar plate injury, claw toe, hammer toe, nerve involvement or return-to-sport readiness on its own. It is a strength measurement that should be interpreted with the broader assessment.
The Ankle Toe Flexion Strength Test measures how much force the client can produce when pushing the toes downward against a fixed or resisted device.
In a Muscle Meter or handheld dynamometer setup, the client usually performs a make test:
the device stays still
the client gradually builds force
the client pushes into the device as hard as safely possible
the peak or average force is recorded
For this article, the default version is a push test. The client pushes the plantar surface of the toes downward into the Muscle Meter or a fixed toe plate.
The exact version should be defined before testing. Toe flexion may mean:
lesser-toe flexion only
all-toe flexion
toe grip against a bar or plate
isolated toe flexion against a small pad
seated non-weight-bearing testing
standing functional toe flexion testing
A strap-stabilised or fixed setup may also be used. This can reduce the influence of assessor strength and improve consistency, especially when several staff members need to repeat the same protocol.
A reliability study developed methods for doming, hallux flexion and lesser-toe flexion strength using dynamometry, showing that toe flexion can be quantified when the method is clearly controlled.
The Muscle Meter is a handheld dynamometry tool used to measure force output during push, pull and isometric strength assessments. When used on its own, the Muscle Meter primarily measures peak force, which is the highest force value produced during the test.
When the Muscle Meter is used with Measurz, the assessment can be recorded, analysed and interpreted with a broader set of strength and force-time metrics. Depending on the test setup, protocol and available data, Measurz and the Muscle Meter can be used to assess and record:
Peak force
Impulse
Torque
Rate of torque development
Rate of force development
Time to peak
Fatigue index
These metrics help professionals move beyond a single strength number and better understand how force is produced, how quickly it is produced, how long it is sustained, and how performance changes across repeated efforts.
For the Ankle Toe Flexion Strength Test, the most useful routine metric is usually peak force. Other metrics may be useful in specific situations:
Impulse may be useful if sustained toe flexion force over a selected time window is relevant.
Rate of force development may be useful when early force production matters, such as rapid foot gripping or sport-specific push-off.
Time to peak may provide context when a client produces toe flexion force slowly.
Torque may be used only if a meaningful lever arm around the toe joints is measured.
Fatigue index may be useful only if repeated or sustained toe flexion efforts are part of the protocol.
Not every test needs every metric. The most appropriate metric depends on the test goal, body region, setup, client population, device placement, protocol quality and the professional question being asked.
The Muscle Meter and Measurz should be used for measurement, assessment reasoning, comparison, education and progress tracking. They should not be positioned as diagnosing a condition, confirming readiness, clearing participation or explaining symptoms on their own.
Toe flexion strength testing may be useful because the toe flexors contribute to foot stability, balance and push-off.
The test can help professionals:
establish a baseline strength score
compare left and right toe flexion force
monitor progress after training or rehabilitation
track changes after foot, ankle or toe symptoms
identify whether effort is limited by pain, fatigue, cramping or confidence
support client education with objective data
compare strength with gait, balance, calf raise or running tasks
record consistent strength information in Measurz
The test should support assessment reasoning. It should not be used as a stand-alone diagnostic or clearance measure.
When used independently, the Muscle Meter measures peak force.
When used with Measurz, Muscle Meter testing can support deeper analysis of force and strength performance, including:
Peak force: The highest force produced during the test.
Impulse: The total force applied across a selected time period.
Torque: The rotational force produced around a joint when force and lever arm are considered.
Rate of torque development: How quickly torque is produced.
Rate of force development: How quickly force is produced.
Time to peak: How long it takes to reach the highest force or torque value.
Fatigue index: How much performance declines across repeated or sustained efforts.
For toe flexion, peak force is usually the primary score. Impulse may be useful for sustained gripping or push-off-related questions. Rate of force development and time to peak may be relevant in sport or rapid-control contexts, but they should not be treated as automatically meaningful for every client.
The test may provide insight into:
toe flexion force capacity
lesser-toe force contribution
combined toe flexor strength
side-to-side force differences
confidence producing toe flexion force
pain response during resisted toe flexion
change in force over time
relationship between toe force and function
It does not directly measure:
toe range of motion
plantar plate integrity
plantar fascia status
intrinsic foot muscle size
nerve function
foot posture
gait quality
balance
endurance
power
readiness to return to running, sport or work
Explain the test clearly.
Example wording:
“We are going to measure how much force you can produce when pushing your toes downward into the Muscle Meter. This is a strength test, not a diagnosis. Tell me if you feel pain, cramping, numbness or anything unusual.”
Use:
Muscle Meter, handheld dynamometer or fixed dynamometry device
small flat pad, toe plate, strap pad or suitable attachment
optional strap or fixed frame for stabilisation
chair, plinth or bench
pain rating scale
Measurz recording workflow
Before testing, define whether the test is:
lesser toes only
all toes together
toes 2–5 together
a toe grip style test
a toe press-down style test
seated non-weight-bearing
standing or weight-bearing
Record the version clearly because scores are not interchangeable across different versions.
Default method:
Push test / make test
The client pushes the toes downward into the stationary device.
The professional holds or fixes the device in place.
Alternative method:
Strap-stabilised fixed test
The device or toe plate resists the toe flexion force.
This can reduce the influence of assessor strength.
Push and pull values should be recorded separately. Do not compare them unless the protocol supports that comparison.
Common seated position:
seated on a chair or plinth
hip flexed around 90 degrees
knee flexed around 90 degrees
foot flat or supported depending on setup
ankle near neutral
toes positioned on or against the device
trunk upright
hands resting comfortably
Alternative long-sitting position:
client long-sitting
knee extended or slightly flexed
ankle near neutral
foot stabilised
toes placed against the device
Record the exact position used.
The professional should position themselves to:
stabilise the foot
keep the device aligned with the toe flexion force direction
prevent device slipping
observe compensations
read the device safely
stop quickly if symptoms occur
Record:
ankle position
metatarsophalangeal joint position
interphalangeal joint position if relevant
whether the toes start neutral, slightly extended or flexed
whether the foot is weight-bearing or non-weight-bearing
For routine testing, a consistent neutral or slightly extended starting position may be practical. The chosen position should be repeated at retest.
Place the device against the plantar surface of the toes.
Record placement clearly, such as:
under lesser toes
under toe pads
under distal phalanges
under proximal phalanges
toe plate under toes 2–5
toe bar across toes
distance from MTP joints if measured
Avoid mixing hallux-only values with lesser-toe values unless the purpose is combined toe flexion.
Stabilise:
foot or midfoot
metatarsals if appropriate
ankle position
device position
chair or plinth position
Avoid:
ankle plantarflexion compensation
whole-foot pushing
heel lift
gripping around the device instead of pressing into it
hip or knee pushing
device sliding
toe pain provocation beyond safe limits
Toe flexion testing can be challenging because clients may compensate with the ankle, the whole foot or the hip. A fixed or well-supported setup improves repeatability.
The client attempts to flex the toes:
“push your toes downward into the device”
force is directed downward or plantarward
the device resists the movement
the toes should remain close to isometric, with minimal visible movement
Use consistent instructions:
“Build up gradually.”
“Push your toes down into the device.”
“Keep the rest of the foot still.”
“Push as hard as you safely can.”
“Hold the effort.”
“Keep breathing.”
“Tell me if you feel pain or symptoms.”
Use:
1–2 submaximal practice trials
1 familiarisation maximal effort if needed
consistent cueing
enough rest before recorded trials
Familiarisation is especially important because many clients find isolated toe flexion difficult.
A practical protocol:
2–3 recorded trials per side
3–5 second contraction
30–60 seconds rest between trials
test the same side first each time
record best trial or average of trials
Use the same method at retest.
Use enough rest to reduce fatigue:
30 seconds minimum for low-irritability testing
60 seconds or more for symptomatic clients or repeated efforts
longer rest if pain, cramping or fatigue affects effort
Repeat or mark a trial invalid if:
device slips
the whole foot pushes down
the heel lifts
ankle plantarflexion dominates
toes curl around the device rather than press into it
pain limits effort unexpectedly
the client does not understand the task
compensations make the result unreliable
Stop testing if the client reports:
sharp toe, forefoot or plantar pain
worsening neurological symptoms
cramping that does not settle
dizziness or distress
numbness or unusual symptoms
inability to produce safe effort
For clients with acute forefoot pain, suspected plantar plate symptoms, painful toe deformity, metatarsalgia, recent surgery or high symptom irritability, use a lower-intensity test or defer maximal testing.
Retest using the same:
device
attachment
position
toe group tested
toe placement
toe joint angle
ankle angle
stabilisation
side order
number of trials
contraction duration
rest period
scoring method
unit of measurement
A push test usually means the client pushes into the Muscle Meter or handheld dynamometer.
For toe flexion:
the device is placed under or against the plantar surface of the toes
the client pushes the toes downward
the device stays still
the score usually reflects peak force
Benefits:
practical and simple
useful for baseline testing
easy to repeat when setup is documented
can target lesser toes or combined toe flexion
Limitations:
device placement affects results
compensations are common
small toe surfaces can make placement harder
toe curling versus pressing may change the score
assessor strength and hand stability may influence handheld tests
A pull test may use a strap, toe loop, bar, plate or fixed attachment where the client pulls or presses the toes into resistance.
Benefits:
may improve repeatability when fixed well
may reduce assessor strength influence
useful for repeated monitoring
Limitations:
requires more setup
strap, bar or plate placement must be consistent
values may differ from handheld push testing
should be recorded separately
A fixed setup can improve consistency because the device or toe plate is anchored rather than held by the assessor.
This is often helpful when:
repeated testing matters
toe placement needs to be precise
multiple staff need to test consistently
small changes over time are being tracked
a toe bar or toe plate protocol is used
Push, pull and strap-stabilised scores should not be mixed unless the protocol and evidence support comparison.
Record the exact unit displayed by the device:
kilograms, kg
pounds, lb
Newtons, N
kilograms-force, kgf
pounds-force, lbf
percentage of body weight, %BW
In strict physics terms, force is measured in Newtons, while kilograms are a unit of mass. In applied dynamometry, some devices display force-equivalent values in kilograms. For practical Measurz recording, use the unit displayed by the device and keep the same unit across retesting.
If using the Muscle Meter alone, the primary score is usually peak force.
If using the Muscle Meter with Measurz, additional metrics may be available, including:
impulse
torque
rate of torque development
rate of force development
time to peak
fatigue index
For toe flexion, peak force is usually the most practical primary metric. Impulse may be useful when sustained toe flexion is relevant. Torque is useful only when a clear lever arm is recorded. Rate of force development and time to peak may be useful in sport or rapid push-off contexts. Fatigue index is only relevant when repeated or sustained efforts are part of the protocol.
Do not present force-time metrics as diagnostic or clearance tools.
There is no fixed universal score range. Scores depend on:
device
units
body size
test position
toe group tested
toe joint angle
ankle angle
stabilisation
population
effort quality
pain or symptoms
scoring method
Record whether the final score is:
best trial
average of trials
peak force
left-right difference
percentage of body weight
Either best trial or average trial may be used if it is applied consistently.
A higher score may suggest:
greater toe flexion force output in the tested position
improved ability to generate force against resistance
better side-to-side symmetry if the opposite side is similar
progress from baseline if the protocol is unchanged
A lower score may suggest:
reduced toe flexion force output in that position
pain-limited effort
fatigue
cramping
guarding
reduced confidence
poor familiarisation
poor stabilisation
altered motor control
symptoms affecting effort
A lower score does not explain the reason for the difference on its own.
Side-to-side comparison can be useful when one side is affected.
Record:
left score
right score
difference in kg, lb or N
percentage difference
affected side
dominant side if relevant
Symmetry is useful, but symmetry alone does not confirm readiness or explain symptoms.
Percentage of body weight expresses force relative to body mass.
If the device displays kilograms:
Force in kg ÷ body mass in kg × 100 = percentage of body weight
If the device displays pounds:
Force in lb ÷ body weight in lb × 100 = percentage of body weight
If the device displays Newtons:
Force in N ÷ body weight in N × 100 = percentage of body weight
Example:
body mass = 80 kg
toe flexion score = 14 kg
14 ÷ 80 × 100 = 17.5% body weight
A value of 100% body weight means the client produced force equal to their body weight. A value of 50% body weight means the client produced force equal to half their body weight.
Body weight percentage may help with:
comparing clients of different body sizes
interpreting force relative to the body the client needs to move
tracking changes if body mass changes
comparing to matched reference data
Limitations:
body weight percentage values are test-specific
they should not be compared across different muscle groups
they should not be compared across different devices or protocols unless closely matched
they are not universal pass/fail thresholds
they should be interpreted with symptoms, function, goals and related findings
The score does not prove:
diagnosis
cause of weakness
plantar fascia pathology
plantar plate injury
metatarsalgia cause
toe deformity severity
nerve injury
readiness to run
readiness for sport
readiness for work duties
effectiveness of one intervention by itself
Published toe flexion strength values exist, but they are highly protocol-specific.
A study on functional assessments of foot strength compared seated dynamometer toe flexion with standing pressure-mat testing and found that seated tests may better isolate the toe flexors, while standing tests may be more functional. This means values from one method should not be applied directly to another setup.
A reliability study of doming and toe flexion testing reported novel methods for measuring doming, hallux flexion and lesser-toe flexion strength, reinforcing that toe flexion can be tested but needs clear protocol documentation.
A 2019 study of a bespoke foot muscle strength dynamometer found that the device could accurately and repeatedly measure toe flexor torque, but this evidence applies to that specific device and protocol rather than every Muscle Meter setup.
For older adults, toe flexor strength has been linked with balance in several studies, but toe grip strength, toe flexor torque and isolated toe flexion force are not interchangeable measurements. A systematic review concluded that stronger toe flexor muscles may improve postural balance in adults aged 60 years and older, while noting the evidence was mainly observational.
For this exact Measurz Muscle Meter toe flexion setup, broad universal norms or body-weight percentage thresholds are not appropriate unless the protocol and population match the reference source.
Use practical comparison guidance:
compare left and right sides
compare with the client’s own baseline
use the same device and unit
calculate % body weight if useful
compare only with matched protocols where available
interpret with pain, toe ROM, gait, balance and activity demands
avoid universal pass/fail thresholds
At the time of writing, high-quality peer-reviewed normative or body-weight percentage reference values for this exact Muscle Meter toe flexion test, device, position and population appear limited. Interpretation should rely more heavily on baseline comparison, side-to-side comparison, repeated testing, internal benchmarks, client goals, symptoms, confidence, movement quality and related assessment findings.
In youth clients, toe flexion testing may be useful for:
baseline strength profiling
monitoring growth-related changes
comparing sides after injury
tracking progress over time
A higher score may suggest greater force output in the tested position. A lower score may suggest reduced force output, but it may also reflect coordination, attention, test unfamiliarity or confidence.
In youth clients, changes in force output may reflect:
growth
maturation
improved coordination
familiarisation
strength adaptation
confidence
body size changes
Adult reference values should not be applied unless evidence clearly supports the comparison.
For general fitness clients, Muscle Meter testing is often most useful for:
baseline comparison
progress tracking
side-to-side comparison
education
monitoring response to training
A higher score may suggest greater force output. A lower score may suggest reduced force capacity, but it should be interpreted with activity level, symptoms, toe range of motion, footwear and test familiarity.
Repeated testing is usually more useful than one isolated value.
In older adults, toe flexion strength may be relevant to:
balance
walking
push-off
foot stability
uneven-ground confidence
daily movement
Toe flexor strengthening has evidence suggesting potential benefit for balance in adults aged 60 years and older, but the evidence base is mainly observational and should not be used to overstate the meaning of one score.
Older adults may need:
slower ramp-up
more familiarisation
longer rest
cautious effort cues
careful symptom monitoring
For athletes, toe flexion strength may be relevant to:
push-off
sprinting
jumping
cutting
landing
balance
foot stiffness and control
return-to-training monitoring
A higher force score may suggest greater capacity in the tested position, but performance also depends on:
rate of force development
impulse
power
coordination
reactive strength
calf strength
ankle mobility
footwear
surface
sport skill
workload tolerance
For athletes, Measurz force-time metrics may be useful when the protocol is designed well. For example, rate of force development and time to peak may provide more context than peak force alone when rapid push-off or foot gripping is relevant. These metrics still should not be treated as diagnostic or clearance tools.
In workplace or occupational settings, toe flexion testing may provide context for:
walking
stairs
ladders
prolonged standing
uneven surfaces
footwear tolerance
carrying tasks over variable surfaces
The score should be interpreted alongside:
job demands
symptoms
footwear
fatigue
balance
gait
task exposure
professional judgement
Do not use one force score to clear a worker for full duties.
For clients returning after foot, ankle or lower-limb injury, toe flexion testing may help monitor:
side-to-side force recovery
confidence producing force
pain during resisted toe flexion
baseline-to-retest change
relationship with gait, balance and calf raise tasks
A side-to-side difference may provide useful monitoring information, but symmetry alone does not confirm readiness or explain symptoms.
Pain may reduce force output through:
guarding
apprehension
reduced confidence
fatigue
cramping
symptom flare
unfamiliarity with loading
A lower force score may reflect reduced force capacity, pain, guarding, apprehension, fatigue or test unfamiliarity. It should not be used to explain the cause of pain on its own.
Always record pain during the test.
A client may produce a high absolute force score but a lower value relative to body weight.
This may be relevant for bodyweight tasks such as:
walking
running
stair climbing
stepping
jumping
changing direction
Body-weight percentage can help contextualise force relative to the body being moved, but it should be interpreted with function, symptoms and goals.
Reliability describes how consistent the test is when repeated.
Validity describes whether the test measures what it is intended to measure.
SEM estimates measurement error around a score.
MDC estimates how much change may be needed to exceed measurement error.
Typical error and coefficient of variation help explain normal variation across repeated testing.
Toe flexion testing can be reliable when the protocol is well controlled, but method matters.
A reliability study of doming, hallux flexion and lesser-toe flexion testing reported methods for quantifying foot muscle strength with dynamometry and highlighted the importance of consistent test setup.
A bespoke foot muscle strength dynamometer study found good repeatability and accuracy for toe flexor torque, but its findings are specific to that device and protocol.
A 2023 intrinsic foot muscle dynamometer study reported moderate-to-excellent reliability and validity for a novel foot strength device, supporting the broader idea that foot strength can be quantified when the setup is controlled. However, those values should not be treated as interchangeable with every Muscle Meter toe flexion setup.
For the exact Measurz Muscle Meter toe flexion protocol, high-quality peer-reviewed evidence reporting SEM, MDC, typical error or coefficient of variation appears limited unless the device, position and stabilisation match a published protocol.
Reliability is stronger when you standardise:
device
attachment
toe group tested
toe joint angle
ankle angle
client position
device placement
stabilisation
force direction
contraction duration
rest period
trial selection method
symptom recording
A change is more meaningful when:
it exceeds known measurement error for a matching protocol
it is repeated across sessions
it aligns with improved function
symptoms are stable or improved
effort quality is consistent
the same device and setup were used
Common errors include:
not recording which toes were tested
not recording the test position
changing the toe joint angle at retest
placing the device inconsistently
allowing whole-foot pushing
allowing heel lift
allowing ankle plantarflexion to dominate
mixing hallux-only and lesser-toe tests
not stabilising the foot
using different devices across sessions
mixing kg, lb and N without conversion
not recording pain during the test
treating the score as a diagnosis
using symmetry as the only readiness marker
assuming every Measurz force-time metric is relevant to every test
Limitations include:
device placement affects results
toe angle affects force output
toe group tested changes the score
pain and apprehension can reduce effort
cramping can affect later trials
normative values are protocol-specific
body-weight percentage values are not universal
torque requires an accurate lever arm
rate of force development requires high-quality time-series data
fatigue index requires repeated or sustained effort testing
the test measures force in one position, not full movement performance
The Ankle Toe Flexion Strength Test may help with:
baseline toe flexor strength testing
monitoring toe flexion strength over time
left-right comparison
foot and ankle injury progress tracking
balance and foot-control context
running and push-off context
sport performance support
workplace task assessment
client education
It is most useful when combined with:
toe range of motion
1st toe flexion strength if tested separately
1st toe extension range of motion
ankle dorsiflexion strength
calf raise testing
balance testing
gait observation
hop or jump testing where appropriate
pain and symptom notes
footwear and workload history

reporting quality
It measures isometric force output during toe flexion, usually by having the client push the toes downward into a Muscle Meter, handheld dynamometer or toe plate.
When used on its own, the Muscle Meter primarily measures peak force, which is the highest force value produced during the test.
When the Muscle Meter is used with Measurz, the assessment may support additional metrics such as impulse, torque, rate of force development, rate of torque development, time to peak and fatigue index. These metrics are only meaningful when the test setup and data quality support them.
Not always. This test may assess lesser-toe flexion, all-toe flexion or toe grip depending on the setup. Isolated 1st toe flexion should be recorded separately.
The common Muscle Meter version is a push or make test. The client pushes the toes downward into a stationary device. Strap-stabilised or fixed setups may also be used, but they should be recorded separately.
The test may involve flexor digitorum longus, flexor digitorum brevis, intrinsic foot muscles and other toe flexors, depending on the toe group and setup.
A lower score may suggest reduced force output in that position, but it does not explain why. Pain, fatigue, cramping, guarding, poor familiarisation, symptoms or poor setup may all influence the result.
No. It may show reduced toe flexion force or pain during testing, but it does not diagnose the cause. It should be interpreted with symptoms, history, toe range of motion, gait, footwear, loading history and related findings.
No. It can support strength monitoring, but return-to-sport reasoning should also consider symptoms, range of motion, balance, hopping, running, cutting, workload, footwear, fatigue, confidence and professional judgement.
The Ankle Toe Flexion Strength Test measures isometric toe flexion force.
The exact toe group tested must be recorded.
The Muscle Meter alone primarily measures peak force.
When used with Measurz, additional metrics such as impulse, torque, rate of force development, time to peak and fatigue index may be recorded or analysed when relevant.
Peak force is usually the most useful primary metric for this test.
Record the exact device, attachment, toe group, toe position, ankle angle and units.
Body-weight percentage can help compare force relative to body size but is not a universal pass/fail value.
Reliability depends on consistent setup, stabilisation, device placement and instructions.
Measurz should record score, units, side, trials, pain, symptoms, body mass, comparison side and retest conditions.
