The Lafayette Grip or Pinch Dynamometers are hydraulic strength measuring instruments. They are designed for routine assessment of the grip and/or pinch strength of a patient or can also be used in the evaluation of hand trauma or disease. As the patient either grips or pinches the device, a column of hydraulic fluid activates a pressure gauge mounted on the top of the device. The gauge indicates the pinch or grip force in pounds (lbs) or kilogram force (kgf). A peak needle shows the maximum force applied during a single test. The peak needle is manually reset at the end of the test and peak values are recorded manually. The grip dynamometers also feature an adjustable handle that can accommodate five different grip positions. The Stainless Steel Short Finger Goniometer is used for easy range-of-motion measurements of metacarpal, phalangeal, and interphalangeal joints. There are linear inch and centimeter markings on both sides of the protractors, in opposite directions. The protractors measure 0-150° in 5° increments. Stainless steel. Latex free. Clearly marked numbers make measuring easy. Measures 5.75 inches long.
A non-powered, mechanical instrument designed to assess neuromuscular function by measuring the force or power exerted by the muscles of the hand/forearm to squeeze/pinch an object. It is used to assess a patient's grip and/or pinch strength in clinical or research settings, typically as part of a rehabilitation program for geriatric patients or those who have suffered a stroke. This device is commonly known as a Vigorimeter. It typically consists of various size squeeze bulbs and an analogue manometer to record the exerted effort. The patient will typically be asked to perform the test a few times so that the physician can obtain a mean value.
