Range of motion (ROM) of the cervical spine was evaluated in 8 control subjects during flexion-extension, rotation and lateral bending movements. The test was repeated on two separate occasions. The ROM test-retest difference ranged from 1.42 degrees for right axial rotation to 9.11 degrees for left axial rotation. The test showed good reliability, with an intraclass correlation coefficient which was higher than 0.74 in extension movement and excellent in flexion, axial rotation and lateral bending. In conclusion, the method proposed for the 3D kinematic analysis of neck movement proved to be useful and non-invasive and to show good-excellent reproducibility. Furthermore the method is easily applicable in clinical practice to evaluate neck function in cervical spine disorders.

Materials and methods: Ten volunteers candidate to partial medial meniscectomy underwent motion analysis before surgery, six months and one year after. Ten healthy volunteers acted as a control group Data were acquired by means of Vicon motion analysis system Results: In gait patterns investigation, joint kinematics does not show significant modifications before and 6 months after surgery, 12 months after surgery hip and knee show a greater flexion. The dynamic analysis stresses alterations in knee sagittal moment. Before surgery the knee flexion moment is reduced. After partial meniscectomy the knee flexion moment increases in both the limbs. In squatting investigation, main focus was on repeatability. Before surgery high inter subjects variability affects knee joint angle; while after surgery high variability affects also hip and ankle. Conclusions: After meniscectomy, gait and squatting patterns are still altered. Before surgery, the joint mechanical structure is not highly altered and modifications are mainly due to pain avoidance schemas; after partial meniscectomy, pain disappears and the new joint behaviours are probably caused by the new mechanical asset and/or proprioceptive mechanisms.

The main goal of the "Clockwork" project was to create a healthy and comfortable environment by supporting middle-aged to older adults in the synchronization of their circadian rhythms. Particularly, the project was intended to target shift workers, such as healthcare professionals, who are greatly affected by chronodisruption, which can lead to health issues, long absences or early retirement. The project was aimed to enhance external synchronizers enabling users to maintain a healthy circadian rhythm by introducing some modifications in their environment. For this scope, the develpment and testing of three main tools was pursued: an activity monitoring device, a feedback and support application framework and an innovative environmental circadian empowering system module, which includes the design of a lighting device, a wireless sensor network, and actuators to re...

Effective and continuative rehabilitation therapies are needed to regain upper limb functionalities, but high costs and lack of qualified personnel highlight the need of new technological solutions. This paper presents a system for the rehabilitation of upper limb in home-settings using light and low-cost equipment. The system uses RF technology to implement functional exercises resembling Activities of Daily Living (ADLs). Hardware and software have been developed for automatically guiding the execution of the rehabilitation exercises and sessions, allowing the patients to perform the therapy at home. The properties of the RF signals are used to compute metrics able to describe and evaluate the performance of the execution such as task execution time, velocity profile and distance covered. A set of exercises has been implemented and preliminary tested on a...

The otolith contribution to postural control is achieved by the integration of otolith inputs and peripheral afferent inputs involved in crossed reflex pathways. This study shows that a functional linkage between otolith signals and activity in lower limb muscles is detectable in normal human gait. The otolith input appears to dominate particularly the neck proprioceptive and gaze motor influences during normal gait. This is demonstrated by an increase of tibialis anterior muscle activity during retroflexion of the head/neck, leading to an increased stability and counteracting possible perturbations. It is also shown by decrease of coordination during the movement caused by larger displacement of the centre of gravity demonstrated in vector diagrams.
