“…This method is time consuming, estimates the spatial accuracy of the load measurement across the platform and can be affected by load positioning inaccuracies. Some diagnostic modalities, like dynamic posturography [72], require the acquisition of dynamic information and a dynamic calibration to evaluate the FPs response to dynamic loads: testing procedures can involve devices devoted to handle calibrated weights either manually or mechanically. Since the manual handling of masses usually limits the dynamic characterization, the calibration systems using mechanical handling are preferable.…”

Nowadays force platforms are widely employed both for diagnostic purposes and for monitoring the execution of motor tasks such as stance, both static and perturbed, and gait. Moreover, even if a clinical assessment based on the knowledge of the forces the patients can exchange with the environment can be useful, some guidelines are needed to determine the practical limitations of the measurements for motion analysis and postural control. In particular, in situ calibration is a fundamental practice especially when the force platforms are either used as reference or are connected with other devices in the measurement chain. Several calibration procedures for force platforms have been proposed in the literature, some of them dealing with only one force component, others with all the force and moment components, and some research groups have also developed and tested some innovative devices or introduced some corrective equations, performing either static or dynamic calibration.

“…Dynamic posturography was performed using an electrically actuated robotic device, the RotoBit 3D , which permits arbitrary rotations -in terms of roll, pitch and yaw directions -around a fixed point. In brief, RotoBit 3D [23][24][25][26][27][28] is characterized by: a workspace of about AE108 for roll and pitch when yaw is in the range AE158, a phase delay of 18, and an amplitude error 1.5%. The RotoBit 3D was installed in the middle of a 10-m walkway of the laboratory.…”

“…In the present study we decided: (i) to use an in-house developed 3D robotic device [23][24][25][26][27][28], which could continuously change the rotation direction and which could be set at different amplitudes and frequencies; and (ii) to conduct quantitative assessments of upper body kinematics. In our first working hypothesis we sought to confirm that the presence of visual information, when healthy adults were subjected to continuous 3D perturbation, would induce a greater upper-body stabilization than that occurring when vision is absent.…”

We explored how changes in vision and perturbation frequency impacted upright postural control in healthy adults exposed to continuous multiaxial support-surface perturbation. Ten subjects were asked to maintain equilibrium in standing stance with eyes open (EO) and eyes closed (EC) during sinusoidal 3D rotations at 0.25 (L) and 0.50 Hz (H). We measured upper-body kinematics--head, trunk, and pelvis--and analyzed differences in horizontal displacements and roll, pitch, and yaw sways. The presence of vision significantly decreased upper-body displacements in the horizontal plane, especially at the head level, while in EC the head was the most unstable segment. H trials produced a greater segment stabilization compared to L ones in EO and EC. Analysis of sways showed that in EO participants stabilized their posture by reducing the variability of trunk angles; in H trials a sway decrease for the examined segments was observed in the yaw plane and, for the pelvis only, in the pitch plane. Our results suggest that, during continuous multiaxial perturbations, visual information induced: (i) in L condition, a continuous reconfiguration of multi-body-segments orientation to follow the perturbation; (ii) in H condition, a compensation for the ongoing perturbation. These findings were not confirmed in EC where the same strategy--that is, the use of the pelvis as a reference frame for the body balance was adopted both in L and H.

“…The two assessments may provide not overlapping information, as the same movement may be generated with different combinations of the redundant muscle system. Typical examples of kinematic analysis combined with EMG measures allowed us to examine the effects of rehabilitation in hemiplegic children [ 122 ], revealing that the combined analysis can highlight the differences in the postural responses between the less-affected and more-affected sides. In patients with spasticity, biomarkers of spasticity were extracted from kinematics and EMG describing the biomechanical and neurogenic components of spasticity [ 123 ].…”

In clinical scenarios, the use of biomedical sensors, devices and multi-parameter assessments is fundamental to provide a comprehensive portrait of patients’ state, in order to adapt and personalize rehabilitation interventions and support clinical decision-making. However, there is a huge gap between the potential of the multidomain techniques available and the limited practical use that is made in the clinical scenario. This paper reviews the current state-of-the-art and provides insights into future directions of multi-domain instrumental approaches in the clinical assessment of patients involved in neuromotor rehabilitation. We also summarize the main achievements and challenges of using multi-domain approaches in the assessment of rehabilitation for various neurological disorders affecting motor functions. Our results showed that multi-domain approaches combine information and measurements from different tools and biological signals, such as kinematics, electromyography (EMG), electroencephalography (EEG), near-infrared spectroscopy (NIRS), and clinical scales, to provide a comprehensive and objective evaluation of patients’ state and recovery. This multi-domain approach permits the progress of research in clinical and rehabilitative practice and the understanding of the pathophysiological changes occurring during and after rehabilitation. We discuss the potential benefits and limitations of multi-domain approaches for clinical decision-making, personalized therapy, and prognosis. We conclude by highlighting the need for more standardized methods, validation studies, and the integration of multi-domain approaches in clinical practice and research.
