Brief summary
In patients with Spinal Cord Injury (SCI), trunk and therefore postural control (both in statics and dynamics) are impaired, often with strong consequences on daily life activities. Therefore, improvement and reinforcement of trunk control are primary rehabilitation (rehab) goals. For the evaluation of trunk control in SCI people, still today no tests and scales are definable as gold standards. Nowadays, for evaluation and rehab purposes of trunk control, balance and proprioception, in both sitting and standing positions, conventional rehabilitation can be supplemented with robotic treatments, e.g. through the Hunova® device (by Movendo Technology). Several studies have demonstrated that conventional rehab associated with robotic training is able to influence functional and motor outcomes in stroke patients, while little evidence is available on SCI patients, also on the number of robotic sessions needed. The present randomized controlled study primarily aims to demonstrate the effects on trunk control of an integrated rehab treatment (standard plus Hunova®), compared to the standard alone and to gain evidence on the better rehabilitation scheme in terms of number of Hunova® sessions. The correlation between the variation of trunk control, measured by the output data of the Hunova® device itself - ideally more objective - and that assessed through a validated clinical scale, will also be estimated.
Detailed description
In SCI patients trunk and therefore postural control (both in statics and dynamics) are impaired, often with strong consequences on daily life activities. Postural control is defined as the ability to maintain balance despite internal and external perturbations, with the aim of bringing the person's barycenter within his standing area. Therefore, improvement and reinforcement of trunk control are primary rehab goals. For the evaluation of trunk control in SCI people, still today no tests and scales are definable as gold standards. Only a few are considered as more reliable, some of them suitable for acute/subacute SCI, some others for chronic SCI. In some published studies, inertial sensors have been used for a more precise evaluation of the Center of Pressure (COP), of the sway area, in relation to the trunk control, but further validation studies are needed. The use of more objective tools could provide additional information on the behavior of SCI people on postural control, thus not only on muscle strength. Of particular interest are the less or more complex compensation strategies implemented and the muscle activation patterns involved in trunk control, assessable through e.g. surface electromyography. Nowadays, for rehab purposes of trunk control, balance and proprioception, in both sitting and standing position, conventional rehab can be supplemented with robotic treatments, e.g. through the Hunova® device (by Movendo Technology). Several studies have demonstrated that conventional rehab associated with robotic training is able to influence functional and motor outcomes in stroke patients, while little evidence is available on SCI patients, also on the number of robotic sessions needed. The same Hunova® device also allows parameters evaluation by means of its output data. The present randomized controlled study primarily aims to demonstrate the effects on trunk control of an integrated rehab treatment (standard plus Hunova®), compared to the standard alone and to gain evidence on the better rehab scheme in terms of number of Hunova® sessions. The correlation between the variation of trunk control, measured by the output data of the Hunova® device itself - ideally more objective - and that assessed through a validated clinical scale, will also be estimated. Randomization will be stratified, based on SCI lesion completeness. A 1:1 allocation ratio will be used for each stratum.
Interventions
OTHERStandard rehabilitation
Carried out 3h/day, 5 days/week at the Montecatone Institute. It implies a multiprofessional approach through: * physiotherapy; * occupational therapy; * sports rehabilitation.
DEVICEHunova® rehabilitation
Performed in a dedicated gym of the Montecatone Institute, 1 hour/day, 5 days/week, in the presence of a physiotherapist. Depending on the improvement of the person and of his skills acquisition, the degree of tilting of the Hunova® seat in the various planes may vary.

Masking description
After selection and enrollment, just before the beginning of the 4-week rehabilitation period, baseline assessments are carried out and patients are randomized. Due to the nature of the Hunova® treatment, blinding of patients and researchers involved in treatment administration will not be possible. Blinding is thus forecast for outcomes' assessors and statisticians only.
