Effectiveness Analysis of Armeo Spring Device as a Rehabilitation Treatment in Spinal Cord Injured Patients

Spinal Cord Injury Cervical Clinical Trial

Official title: Effectiveness Analysis of Armeo Spring Device as a Rehabilitation Treatment in Spinal Cord Injured Patients

Status Completed

Clinical Trial Summary

Loss of motor function is a consequence after a spinal cord injury (SCI). The incidence of SCI varies greatly from 12.1 to 57.8 cases per million depending on the country. More than 50% of people with SCI have impaired upper limb (UL) function, experiencing limitations in performing functional tasks. In this context, one of the rehabilitation objectives is to achieve the maximum level of independence in the patient in the performance of activities of daily living (ADL).

Within the clinical setting, the main motivation in the use of robotic devices and/or exoskeletons for a rehabilitation purpose focuses on the fact that these help therapists in administering repetitive manual therapies to patients during exercises. There is evidence that the amount of therapy patients receive is insufficient. Without creating additional time demands on clinicians, robotic devices can perform the repetitive mechanical aspects of therapy, increasing the amount of therapy that patients receive. However, the current evidence in stroke patients suggests that the improvements observed are due to the intensity of the therapy, regardless of whether the administration of rehabilitation is due to robotic devices and/or traditional means.

The main objective of this study is to analyze the effectiveness of the commercial Armeo® Spring system (Hocoma AG, Switzerland) and a Virtual Reality application to repeatedly work the ADL from drinking from a glass, in people with cervical SCI. The ADL of drinking has been chosen, as a representative activity of those related to food, which requires control, strength and coordination of the UL. The study is carried out at the Hospital Nacional de Parapléjicos with the collaboration of Occupational Therapy Unit, the Rehabilitation Department, and the Biomechanics and Technical Aids Unit. This effectiveness is measured in terms of functional improvements and in the quality of the UL movements performed.

Clinical Trial Description

In the literature, there are several studies of the upper limb applied to ADL. The analysis of complete ADL is related to the clinical objectives of the rehabilitative treatment of the UL. An important part of rehabilitation after neurological injuries consists of training activities aimed at fulfilling a function or objective, in which patients have to move their arms continuously repeating certain movement patterns. This is currently one of the main strategies to promote recovery of upper limb function in people who have suffered a spinal cord injury (SCI) o stroke.

Within the clinical setting, the main motivation in the use of robotic devices and/or exoskeletons for a rehabilitation purpose focuses on the fact that these help therapists in administering repetitive manual therapies to patients during exercises. There is evidence that the amount of therapy patients receive is insufficient. Without creating additional time demands on clinicians, robotic devices can perform the repetitive mechanical aspects of therapy, increasing the amount of therapy that patients receive. On the other hand, the use of robotic devices is closely linked to the use of virtual reality (VR) applications. VR interfaces provide feedback to the patient, increasing their level of motivation and adherence to the task during therapy. In this way, therapies with robotic devices and / or exoskeletons increase the amount of rehabilitation, the level of motivation of the patient, and training oriented to fulfill a function or task. Rehabilitation of patients with robotic device-based therapies in addition to traditional therapies could improve functional outcomes. However, the current evidence in stroke patients suggests that the improvements observed are due to the intensity of the therapy, regardless of whether the administration of rehabilitation is due to robotic devices and/or traditional means.

The main objective of this study is to analyze the effectiveness of the commercial Armeo® Spring system (Hocoma AG, Switzerland) and a Virtual Reality application to repeatedly work the ADL from drinking from a glass, in people with cervical SCI. The ADL of drinking has been chosen, as a representative activity of those related to food, which requires control, strength and coordination of the UL. The study is carried out at the Hospital Nacional de Parapléjicos with the collaboration of Occupational Therapy Unit, the Rehabilitation Department, and the Biomechanics and Technical Aids Unit. This effectiveness is measured in terms of functional improvements and in the quality of the UL movements performed.

The secondary objectives are:

• To validate the applicability of the Virtual Reality developed to work the upper limb during the execution of a complete AVD.

• To know the usability and level of acceptance of this therapy in patients with spinal cord injury and UL functional impairments.

• To quantify the differences between the functional patterns of both groups, intervention and control, by means of objective measures, functional scales and measures of the quality of movement, collected in patient evaluations, before, during and after treatment.

• To determine the influence of the RV and the Armeo Spring exoskeleton on the motor recovery of patients with spinal cord injury and UL impairments. ;
