An intelligent hand prosthesis and evaluation of pathological and prosthetic hand function
An intelligent hand prosthesis and evaluation of pathological and prosthetic hand function
Commercial hand prostheses provide the user with insufficient dexterity and functionality due to the highly restricted number of prehensile patterns that may be achieved. Demographic studies show that the potential market for upper limb prostheses is largely stable, and with the identification of the functional differences and inadequacies of existing prostheses, users are increasingly dissatisfied with the status quo.
The six degree of freedom Southampton-Remedi hand has been developed to address this need. The mechanical adaptability of the lightweight prosthesis provides a wide range of grip types with a greater degree of stability than produced by any conventional device. This is due to the ability of each digit to independently contribute to the integrity of the grip.
The command and coordination of more than a single device or function is difficult and frequently increases the cognitive burden on the user. The optimal use of multifunction prostheses lies in the synergistic control of several actuators without increasing the number of inputs that a user must independently initiate. This has been achieved by the development of a hybrid SAMS-UNB controller that enables the user to directly implement prehensile patterns from their myo-signal whilst the process of maintaining a secure grasp remains automated.
The effectiveness of the new prosthesis and controller must be quantified in terms of its functionality. However there is little or no conformity to a standardised and objective procedure for the assessment of either pathological or prosthetic hand function. The Southampton Hand assessment Procedure (SHAP) has been designed to account for these shortcomings and therefore allow the evaluation of hand function in the clinical setting. The outcome measure is a contextual rating of functionality (relative to that of ‘normal’ hand function), which enables the clinician to initially determine the subject’s disability, and subsequently monitor their performance throughout a course of treatment or rehabilitation.

Abstract
Commercial hand prostheses provide the user with insufficient dexterity and functionality due to the highly restricted number of prehensile patterns that may be achieved. Demographic studies show that the potential market for upper limb prostheses is largely stable, and with the identification of the functional differences and inadequacies of existing prostheses, users are increasingly dissatisfied with the status quo.
The six degree of freedom Southampton-Remedi hand has been developed to address this need. The mechanical adaptability of the lightweight prosthesis provides a wide range of grip types with a greater degree of stability than produced by any conventional device. This is due to the ability of each digit to independently contribute to the integrity of the grip.
The command and coordination of more than a single device or function is difficult and frequently increases the cognitive burden on the user. The optimal use of multifunction prostheses lies in the synergistic control of several actuators without increasing the number of inputs that a user must independently initiate. This has been achieved by the development of a hybrid SAMS-UNB controller that enables the user to directly implement prehensile patterns from their myo-signal whilst the process of maintaining a secure grasp remains automated.
The effectiveness of the new prosthesis and controller must be quantified in terms of its functionality. However there is little or no conformity to a standardised and objective procedure for the assessment of either pathological or prosthetic hand function. The Southampton Hand assessment Procedure (SHAP) has been designed to account for these shortcomings and therefore allow the evaluation of hand function in the clinical setting. The outcome measure is a contextual rating of functionality (relative to that of ‘normal’ hand function), which enables the clinician to initially determine the subject’s disability, and subsequently monitor their performance throughout a course of treatment or rehabilitation.
