The Paper-Grip Test – 1st Toe [Muscle Meter] measures how much force is required to pull a card or paper strip from underneath the big toe while the client attempts to grip it. It is commonly used to assess hallux gripping force in a practical, foot-strength-focused setup. This can provide useful context for balance, walking, running, foot control, toe function, lower-limb loading, falls-risk context and progress tracking.
The Muscle Meter is used to quantify the pulling force required to remove the paper or card. When used on its own, the Muscle Meter primarily measures peak force, which is the highest force value recorded during the pull. When used with Measurz, Muscle Meter data can be recorded and analysed with broader force-time metrics, including peak force, impulse, torque, rate of force development, time to peak and fatigue index.
For routine 1st-toe paper-grip testing, peak force is usually the main metric. Force as a percentage of body weight may be useful if directly calculated from the client’s test force and body weight, especially for baseline comparison, side-to-side comparison and retesting. Torque is usually not required unless a specific lever arm and biomechanical model are being used. Rate of force development and time to peak are usually less central because the test focuses on the force required to remove the paper rather than rapid toe force production. Impulse and fatigue index are only relevant if repeated or sustained toe-grip trials are intentionally included.
The result can support assessment reasoning and progress tracking, but it does not diagnose foot pain, toe deformity, neuropathy, falls risk, plantar fasciopathy, balance impairment, sport readiness or work capacity on its own.
The Paper-Grip Test is a practical toe-grip assessment where a paper strip or card is placed under the toe and the client attempts to hold it down while the professional pulls it away.
The 1st-toe version focuses on the hallux, or big toe. The Muscle Meter can be used to quantify the pulling force needed to remove the paper from under the toe.
This makes the test more objective than a simple pass/fail version, because it records a force value rather than only whether the client can hold the paper.
Consistent setup matters because paper material, foot position, toe contact area, skin condition, surface friction, body position, pulling direction, pulling speed and client effort can all affect the result. This test measures toe-grip force in a specific setup. It does not fully measure balance, gait, foot posture, neurological status, falls risk or sport performance on its own.
Prepare the client
Explain that the test measures how strongly they can grip a paper or card with the big toe while it is pulled away.
Record baseline symptoms, toe pain, foot pain, arch discomfort, numbness, altered sensation, fatigue, recent activity, footwear and confidence with the test.
Use one gentle practice trial so the client understands the task.
Set the client position
Use a repeatable position.
A common setup is seated, barefoot, with the foot flat on the floor and the knee flexed.
Record:
seated or standing position
side tested
barefoot or footwear condition
knee angle
foot position
heel position
toe position
surface type
whether body weight is loaded through the foot
paper or card type
Set up the Muscle Meter
Attach or connect the paper/card to the Muscle Meter so the device records the pulling force required to remove it from under the 1st toe.
Record the paper width, paper material, attachment method and whether the pull is straight, angled, horizontal or slightly upward.
Place the paper or card
Place the paper or card under the plantar surface of the 1st toe.
Try to standardise how much paper sits under the toe. The same paper placement should be used for retesting.
Stabilise the position
Ask the client to keep the foot still and avoid lifting the heel, curling the lesser toes excessively, shifting weight, gripping the floor with the whole foot or pressing down through the ankle.
The aim is controlled 1st-toe grip, not whole-foot bracing.
Give clear instructions
Use consistent instructions such as:
“Grip the paper with your big toe and try not to let me pull it away.”
“Keep your foot still.”
“Do not lift your heel.”
“Keep breathing.”
“Tell me if you feel pain, cramping, tingling or anything unusual.”
Record trials
Use one practice trial, then record 2–3 measured trials.
Pull the paper consistently until it slips free or the endpoint is reached.
Rest briefly between trials if toe cramping or fatigue occurs.
Record whether the final score uses the best trial or average of recorded trials.
Identify invalid trials
Repeat or mark a trial as invalid if:
the paper placement changes
the heel lifts
the foot slides
the client grips with the whole foot instead of the 1st toe
the paper tears
the Muscle Meter attachment slips
the pulling direction changes
the client curls the lesser toes to assist
pain or cramping limits effort
the pull is performed too quickly or inconsistently
Record symptoms
Record toe pain, arch discomfort, foot cramping, numbness, tingling, confidence, apprehension and symptom response after testing.
For retesting, match the same position, paper type, device setup, paper placement, pull direction, scoring method and symptom recording.
The Paper-Grip Test – 1st Toe [Muscle Meter] is used to quantify hallux gripping force in a practical setup.
It may be useful for:
baseline big-toe grip assessment
side-to-side comparison
monitoring change over time
tracking foot strength after reduced loading
supporting balance and walking assessment
providing context for running, jumping and foot control
comparing toe-grip force with calf strength, ankle mobility and balance
reviewing foot function in older adults
client education
The test should support assessment reasoning. It should not be used as a stand-alone diagnostic or clearance measure.
The test primarily measures the pulling force the 1st toe can resist in the chosen paper-grip setup.
It may provide useful information about:
hallux grip force
side-to-side difference
confidence gripping with the big toe
cramping or symptom response
change in force over time
relationship between toe function and related foot tasks
It does not directly measure:
isolated intrinsic foot muscle strength
nerve conduction
cause of foot pain
falls risk
balance
gait quality
foot posture
plantar fascia status
sport readiness
work readiness
A higher score may suggest greater 1st-toe gripping force in that specific paper-grip setup. A lower score may suggest reduced force, but the reason should be interpreted carefully.
Lower force may be influenced by pain, altered sensation, cramping, poor familiarisation, toe deformity, reduced toe contact, slippery skin, dry skin, fatigue, apprehension, inconsistent paper placement or reduced confidence.
One result should not be interpreted in isolation. Interpretation is strongest when the same setup is repeated over time and reviewed alongside symptoms, balance, gait, foot posture, calf capacity, ankle mobility and functional goals.
Important influences include:
paper type
paper width
paper placement
skin condition
toe contact area
nail position
foot position
body position
surface friction
pulling direction
pulling speed
pain
cramping
altered sensation
client confidence
Published evidence for the enhanced paper-grip test supports quantifying hallux grip force rather than using only a pass/fail result. However, Muscle Meter-specific universal norms for the exact 1st-toe paper-grip setup may be limited.
For routine Measurz use, the most useful comparisons are:
the client’s own baseline
right versus left comparison
change across retests
pain or cramping response
confidence during testing
relationship to balance, walking, running or foot symptoms
force as a percentage of body weight if directly calculated
A side-to-side difference is worth reviewing when it matches symptoms, previous injury, balance findings, gait observations or functional concerns. It should not be used as a strict pass/fail rule.
Reference values provide context, not diagnostic or clearance cut-offs.
Use this order:
compare with the client’s own baseline
compare right and left sides when relevant
consider symptoms during and after testing
consider toe contact and paper placement consistency
review whether compensations were present
compare with related foot, ankle, balance and gait tests
relate the result to walking, running, sport, work or daily-life demands
retest under the same conditions to monitor change
do not use reference values as pass/fail criteria
Use for the maximum force resisted before the paper/card is removed.
Look for consistent setup, side-to-side difference, change from baseline, symptom response and whether the paper placement and pull direction were consistent.
Use only when calculated directly from test force and body weight.
This may provide useful context, especially because body mass influences foot loading, but it should not be treated as a universal target unless comparison data use the same method.
Torque is usually not needed for routine paper-grip testing.
Use only if a specific lever arm and biomechanical interpretation are intentionally included.
RFD is usually not central because the test measures grip force resisting paper removal rather than rapid toe force production.
Use only if the protocol is designed for rapid toe gripping.
Time to peak is usually not central for routine use.
It may be useful only if the same controlled pull pattern is used and force-time behaviour is being reviewed.
Use only if a sustained gripping window is intentionally tested.
Use only if repeated or sustained toe-grip trials are part of the protocol.
Consider attention, coordination, foot size, task understanding and ability to isolate the big toe. Practice trials are useful.
Use the test for baseline foot-strength context, progress tracking and comparison with walking, running or gym goals.
Consider balance, foot sensation, skin condition, toe deformity, cramping, standing confidence and falls-risk context. A lower score may be useful information, but it should not be interpreted without functional assessment.
Consider running, jumping, cutting, landing, balance, footwear and sport-specific foot loading. The result can support a broader foot and ankle profile but does not determine readiness.
Consider prolonged standing, walking surfaces, footwear, stairs, ladders and carrying demands. Do not use one toe-grip score to clear work duties.
Pain, altered sensation, toe deformity, cramping and guarding may influence the result. Record symptoms carefully and compare with related findings.
Absolute force and force relative to body mass may both be useful. Interpret the result in relation to goals, symptoms, foot loading and function.
Repeatability improves when the same setup is used each time.
Record and standardise:
same body position
same side tested
same paper or card type
same paper width
same paper placement
same foot position
same surface
same pulling direction
same pulling speed
same endpoint
same number of trials
same scoring method
same symptom and compensation recording
Enhanced paper-grip testing research supports quantifying hallux grip force with dynamometry, but the test remains sensitive to setup. The Muscle Meter result should be interpreted as protocol-specific.
Common errors include:
inconsistent paper placement
different paper material
pulling too quickly
changing pull direction
allowing the foot to slide
allowing heel lift
allowing whole-foot gripping
not recording skin or toe symptoms
comparing different protocols directly
treating the score as a diagnosis
Limitations include:
testing is setup-dependent
paper friction affects results
toe contact area affects results
pain or altered sensation can reduce performance
the test does not isolate one muscle
universal Muscle Meter norms may be limited
the result does not determine balance, gait, sport or work readiness on its own
The Paper-Grip Test – 1st Toe [Muscle Meter] may be useful for:
establishing a baseline hallux grip score
comparing right and left feet
tracking change over time
reviewing force relative to body weight if directly calculated
supporting foot and ankle assessment
comparing with balance, calf strength, ankle mobility and gait
educating the client about measurable progress
reviewing walking, running, sport, work or daily-life demands
If force is low on both sides, consider assessing toe mobility, foot sensation, calf capacity, ankle mobility, balance, gait and footwear.
If one side is much lower, compare with symptoms, previous injury, foot posture, balance and walking or running observations.
If cramping limits the result, record the response and consider shorter efforts, more rest or a gentler familiarisation trial.
If force improves over time, keep the same setup and monitor whether toe grip, symptoms, confidence and function improve together.

It measures how much force the big toe can resist while gripping a paper or card.
It provides a practical measure of toe-grip force, but it does not isolate one muscle.
It can be if calculated directly from force and body weight. Use it for baseline, side-to-side comparison and retesting rather than as a universal target.
Published Muscle Meter-specific universal norms for this exact setup may be limited. Baseline and retest comparison are usually more useful.
No. It can provide useful foot-strength context, but it does not diagnose balance impairment or predict falls on its own.
Different paper placement, paper type, pull direction, foot position, skin condition, pain, cramping and inconsistent instructions can affect results.
Record side, toe tested, paper type, position, peak force, bodyweight percentage if calculated, symptoms, compensations and retest conditions.
The Paper-Grip Test – 1st Toe [Muscle Meter] measures hallux paper-grip force.
Peak force is usually the main routine metric.
The test is sensitive to paper type, placement, pull direction and foot position.
Percentage of body weight should only be used when directly calculated.
Baseline comparison, side-to-side comparison and retesting consistency are usually more useful than broad norms.
Measurz should capture setup, symptoms, force value, bodyweight-normalised values where calculated and retesting conditions.
