Spinal Cord Injury at C5-C7 Level
Conditions
Brief summary
16 persons affected by Cervical-SCI were recruited for the study and randomly assigned to the Control Group (CG) or to the Experimental Group (EG). Persons of the CG (n = 8) executed 20 sessions of FES for the rehabilitation of hand functions (grasp or pinch), participants of the EG (n = 8) performed 20 sessions of FES and CBA in addition. The primary assessment was a modified version of Bimanual Activity Test (10 tasks); also, SCIM-II and measurement of grasping strength only in participants submitted to grasp rehabilitation were evaluated.
Detailed description
Each participant followed twenty sessions of hand rehabilitation, three times per week. Each treatment, for both CG and EG, lasted about forty minutes. The FES devices chosen for this research stimulated grasp or pinch function: the NESS H200 (NESS Ltd., Ra'anana, Israel) was used if patient needed to improve the grasp functions, otherwise the Microstim (Microstim, Medel, Hamburg, Germany) was used to increase pinch functions. In order to provide FES, the five electrodes of NESS H200 were first humidified with warm water and then inserted in the right size place of the rigid splint worn by the patient, while Microstim was used with four standard electrodes, two for each muscle treated. In both case the stimulation was triggered by the therapist clicking a button (Table 1). The participants of CG received only FES to improve their manipulating skills without the interaction with objects, but only with the muscle contraction induced by the devices. The participants of EG executed FES and CBA treatment which means that during the stimulation they manipulated different tools. In particular, for the first ten sessions the participants were invited to manipulate specific objects: squares, rectangles and pyramids of different sizes; touch on plastic test tubes coated with materials of different consistency; these two exercises were performed both with open and closed eyes. Finally, for the last ten sessions the participants were asked to execute specific tasks, depending on person's life before the lesion.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Performance test: Bimanual Ability Test (BAT) | 2 years | 10 items evaluated, each one from 0 to 60 seconds. Less time needed means better skills |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Spinal Cord Independence Measure (SCIM) | 2 years | The score varies from 0 to 100. Higher the score, patient more independent in its daily life |
| Grasping Strength (GS) | 2 years | Grasping Strength evaluated with a dynamometer (from 1 to 90 kg) more kg means more strength |
