Introduction
The Lafayette Hydraulic Pinch Gauge was designed as a diagnostic tool to measure the strength of
different pinch applications. The pinch gauge has a real time force needle and a peak hold needle.
The real time force needle displays the current force being applied to the gauge. The peak hold needle
displays the maximum force that was applied during the trial.
Operation
The therapist holds the rounded end of the gauge supporting the weight of the instrument with the
pressure pad positioned toward the patient. The gauge must be “zeroed” before each trial. To zero the
instrument turn the center knob counter-clockwise until the peak hold needle returns to zero. With the
therapist still supporting the weight of the instrument, the patient applies pressure to the pinch block
and pressure pad with the thumb and nger being tested.

Applications
The patient should be seated with the test arm at the side of the elbow exed at 90 degrees with the
forearm and wrist in the neutral position.
The various pinch styles include
1. Tip Pinch: Test involving the tip of the thumb and the tip of each or any of the ngers making
certain that the other ngers are not involved.
2. Key Pinch: Test involving the pad of the thumb and the PIP joint of the index nger.
3. Palmar Pinch: Test involving the pad of the thumb and the pads of the index and middle ngers.
Note: Lafayette Instrument Company recommends placing the patient’s thumb on the pressure
pad with the index and pointer ngers on the back when doing the Palmar Pinch test.

Service Tips
The Lafayette Hydraulic Pinch Gauge is designed to provide reliable service, with minimal
maintenance, over a period of many years. To make sure the instrument is reading accurately, it is
recommended to make a few checks, occasionally, as listed below.

Zero-Adjustment Screw
Calibration
The instrument is calibrated at the factory using a
custom calibration device. To ensure proper operation,
the instrument should be returned to the manufacturer
for calibration on a regular, preferably, annual basis.
If the instrument has been dropped or there is some
particular reason to suspect the calibration is in error,
the instrument should be serviced by the manufacturer
immediately.
Zero Reading
The gauge needle may be above or below the zero
reading upon receipt of the instrument. The gauge on
this instrument is sensitive to pressure changes due
to changes in altitude and will most likely require an

adjustment to re-zero the instrument. Follow these steps to return the gauge needle to zero:
1. Unscrew (counter clockwise) and remove the lens from the gauge (the red peak-hold needle is
attached to the lens)
2. Remove the handle (to prevent applying pressure during this process)
3. Place the instrument on a sturdy surface
4. Using a small slotted screwdriver, rotate the slotted screw counter clockwise in the gauge dial
face until the needle is below zero (if it is already zero, turn the cam until it is slightly farther below
zero)
5. Turn the screw in the reverse direction until the gauge needle is almost touching the zero line
6. Reattach the gauge lens and the handle
7. Pick up and squeeze to apply pressure to the instrument a few times
8. Place the instrument back on a sturdy surface and return the red peak-hold needle to zero by
turning the center knob
9. Check to see that the red peak-hold needle is at zero
10. If the red peak-hold needle is not on zero, repeat the steps until the red peak-hold needle is at zero

Red Peak-Hold Needle
Check for excessive friction in the red peak-hold
assembly by turning the peak-hold knob in the lens
counterclockwise. If the peak-hold needle deects
the gauge needle, return the instrument for service.
Likewise, if the red peak-hold needle moves too
freely, (i.e. spins without pressure applied) return the
instrument for service.

Wrist Strap
The Lafayette Hydraulic Pinch Gauge is equipped with a wrist strap. Simply place your hand through
the strap before pinching the pressure pad to protect the instrument from damage if dropped.
Cleaning

with water. Handle can also be cleaned with an isopropyl alcohol wipe. Do not use alcohol on the
plastic gauge faceplate or cover.

Hydraulics
Any sign of hydraulic oil is an indication of damage to the instrument which requires service by the
manufacturer.
Hydraulic Fluid Exposure
Lafayette hand and pinch dynamometers are lled with a biodegradable, plant based hydraulic uid.
Under normal circumstances, the uid is contained within the device and does not come into contact
with the user or patient. If the device is damaged, the uid can leak out and human exposure to the
uid is a possibility. The uid is non-toxic and contains no chemicals known to cause cancer, birth
defects or other reproductive harm. Despite the relative safety of the uid, precautions should be
taken to limit exposure. If exposure occurs, the following guidelines from the Material Safety Data
Sheet (MSDS) of the uid should be followed.
ORAL: DO NOT INDUCE VOMITING. If conscious, give 2 glasses of water. Get immediate medical
attention.

EYE: Flush with water at least 15 minutes. Get medical attention if eye irritation develops or persists.
SKIN: Wash with soap and water. Remove contaminated clothing. Get medical attention if irritation
develops. Launder contaminated clothing before reuse.
INHALATION: Remove exposed person to fresh air if adverse effects are observed. If breathing is
labored, administer oxygen. If breathing has stopped, apply articial respiration. If irritation persists,
get medical attention.
Warranty
The Lafayette Hydraulic Pinch Gauge has a 1 year parts and labor warranty. Please contact our service
department at [email protected] to schedule your yearly calibration or repair. Any
attempt to service or calibrate outside of Lafayette Instrument will void the warranty.
