The objective of the present study was to design and experiment a hand rehabilitation device for domestic intensive and repetitive training for subjects affected by hemiparesis, assuring their active participation during the exercise. The designed system is composed by the Gloreha hand rehabil-itation glove along with its controller PC, and a device for electromyographic signals recording. To assure user’s voli-tional involvement during the rehabilitation session, residual volitional EMG is used to trigger the onset of a predetermined hand movement sequence applied in an open-loop modality. In particular, a target hand movement for the rehabilitation session is defined (i.e., grasping, pitching, etc.), and the patient is required to start the movement. Only when the muscular activity overcomes a predefined threshold, Gloreha supports the patient-initiated movement. The designed controller has been tested on a group of healthy volunteers, and on three neurological patients, with different residual ability. All the users were able to calibrate and correctly use the system, and they reported that the system was more challenging to be used with respect to the standard Gloreha-based rehabilitation session, and required more attention and involvement. The results obtained during the preliminary tests are encouraging, and demonstrate the feasibility of the proposed approach.

Abstract
The objective of the present study was to design and experiment a hand rehabilitation device for domestic intensive and repetitive training for subjects affected by hemiparesis, assuring their active participation during the exercise. The designed system is composed by the Gloreha hand rehabil-itation glove along with its controller PC, and a device for electromyographic signals recording. To assure user’s voli-tional involvement during the rehabilitation session, residual volitional EMG is used to trigger the onset of a predetermined hand movement sequence applied in an open-loop modality. In particular, a target hand movement for the rehabilitation session is defined (i.e., grasping, pitching, etc.), and the patient is required to start the movement. Only when the muscular activity overcomes a predefined threshold, Gloreha supports the patient-initiated movement. The designed controller has been tested on a group of healthy volunteers, and on three neurological patients, with different residual ability. All the users were able to calibrate and correctly use the system, and they reported that the system was more challenging to be used with respect to the standard Gloreha-based rehabilitation session, and required more attention and involvement. The results obtained during the preliminary tests are encouraging, and demonstrate the feasibility of the proposed approach.File | Dimensione | Formato | |
