Evaluation of an integrated sensory glove at decreasing joint flexion degree

The glove remains the main tool for detecting the flexion angles of the hand joints. Semiautomatic measurements of the hand joints are carried out to date with the use of the goniometric glove. This study describes a new data glove equipped with 10 bending sensors, showing results similar to those already existing in the literature. An automatic measurement system has been developed, to analyze the nonlinear behavior of flex sensors through the measurement of the bending angles between hand phalanges. This paper suggests the study of two intermediate joint flexion degree between the open and closed hand, to analyze the non-linearity of sensors in the Wise protocol, extending it. The Wise protocol was applied with two molds to allow two intermediate closure with respect to the open and the closed hand. The dependence of repeatability, reproducibility, reliability and correlation between Range and SD depending on the size of the mold used for the Wise test are also investigated. It has been seen that the size of the mold could influences the Range and SD values.
