In this paper, the accuracy evaluation of the Kinect v2 sensor is investigated in a rehabilitation scenario. The accuracy analysis is provided in terms of joint positions and angles during dynamic postures used in low-back pain rehabilitation. Although other studies have focused on the validation of the accuracy in terms of joint angles and positions, they present results only considering static postures whereas the rehabilitation exercise monitoring involves to consider dynamic movements with a wide range of motion and issues related to the joints tracking. In this work, joint positions and angles represent clinical features, chosen by medical staff, used to evaluate the subject's movements. The spatial and temporal accuracy is investigated with respect to the gold standard, represented by a stereophotogrammetric system, characterized by 6 infrared cameras. The results provide salient information for evaluating the reliability of Kinect v2 sensor for dynamic postures.

Despite low rotigotine doses, when added to levodopa/switched from levodopa+another DA, rotigotine led to greater improvement in UPDRS-II in younger patients (<70 years). Individual patient data revealed clinically meaningful improvements in UPDRS-II in both groups.

We performed an open label single-blind trial with seventeen patients with moderate to severe upper limb spasticity following stroke or traumatic brain injury, treated with an average dose of 165 MU (mouse units) botulinum toxin (range: 100 MU to 210 MU). Evaluation of outcome was carried out analyzing the changes in standard measures of impairment, disability, and quality of life. Spasticity reduction, with increased range of motion (ROM), was observed in all patients, independent of the duration of spasticity. Changes either in "focal" or in "global" disability scores occurred in two subgroups of subjects showing, respectively, residual motor function of the extensor muscles or severe spasticity-related disability. Patients with no residual motricity of the antagonist muscles at the spastic limb, with moderate spasticity, scoring high values on the Functional Independence Measure (FIM) assessment, did not show any disability decrease after treatment. These findings stress the need for an accurate assessment of the patient's impairment and disability to optimize the cost/benefit ratio of BTX application.

This work deals with the design of an interactive monitoring tool for home-based physical rehabilitation. The software platform includes a video processing stage and the exercise performance evaluation. Image features are extracted by a Kinect v2 sensor and elaborated to return the exercises score. Furthermore the tool provides to physiotherapists a quantitative exercise evaluation of subject's performances. The proposed tool for home rehabilitation has been tested on 5 subjects and 5 different exercises and results are presented. In particular both exercises and relative evaluation indexes were selected by specialists in neurorehabilitation.
