Research summary
Objective measurements of basic hand functions such as grip or pinch are reliable indicators of severity of various conditions of the hand and the efficiency of surgical treatment and post-operative rehabilitation of the hand.
Such measurements are established routine in the care of the hand before and after surgery. For decades simple spring-loaded dynamometers such as Jamar grip or pinch dynamometers have been used. These devices only measure single point strength and provide a mere snapshot of total hand strength disregarding variations of the forces over time.
With the advent of minuscule capacitive pressure sensors, many sensors can now be incorporated in a ‘pressure sensor mat’ in recent devices such as Manugraphy device. These devices enable a more comfortable grip measurement for the patient and provide a ‘high definition’ and dynamic measurement of the forces of the hand for the health professional.
These readings are high definition as multiple small sensors record pressure exerted by different areas of the hand simultaneously and are also dynamic as the device is able to capture data from each sensor at a rate of 20 times per second. Therefore the device can show the instantaneous amount of force or the average force per gripping sequence.These devices are already approved and in use in clinics all around the world. However we aim to accurately compare the readings of such devices with the older devices both in normal hands and hands undergoing surgery.
There is an efficient understanding of the correlation of measurements of old devices with pre-and post-operative condition of the hand and the progress of rehabilitation process. This study will define correlation between new and old devices measurements. Furthermore it establishes the normal values of grip forces measured with new device in normal non-surgical hand.REC name
