Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Mental practice with motor imagery, whereby participants visualise themselves grasping objects. Different motor imagery modalities are used (e.g. visual, kinesthetic, etc.) focusing various tenodesis grasping skills (e.g. different seizes of objects, contralateral and ipsilateral tenodesis grasping actions.. etc.). Administration mode: one-on-one supervision by a physiotherapist. Frequency and duration of mental practice sessions: SCI patients underwent 3×30 minutes sessions per week for 5 weeks.

Comparator / control treatment
Posttest level is compared with the baseline pretests level (i.e. before rehabiltiative interventions with mental training) in spinal cord injured patients. Age and sex-matched healthy control participants follow similar a repeated pretests and posttest assessments procedure. They do not recieve rehabilitative interventions but a control task (i.e. playing cards with a physiotherapist 3×30 minutes per week for 5 weeks).

Outcomes
Primary outcome [1] 288025 0
Kinematic analysis of tenodesis grasp actions
Timepoint [1] 288025 0
At weeks 1, 3 and 5 following inclusion and at weeks 1 and 8 following intervention. Experimental intervention is administered during weeks 6 to 10 relative to patient's inclusion.
Primary outcome [2] 288026 0
Magnetoencephalographic cerebral activity during imagined and executed tenodesis grasp actions
Timepoint [2] 288026 0
At weeks 1, 3 and 5 following inclusion and at weeks 1 and 8 following intervention. Experimental intervention is administered during weeks 6 to 10 relative to inclusion.
Primary outcome [3] 288040 0
Autonomic nervous system (i.e. heart rate and electrodermal activity) activity during imagined and executed tenodesis grasp actions. We used an autonomic nervous system acquisition device (E-MOTION) and recorded the electrocardiogram. We also recorded skin resistance responses, using two 50 mm2 unpolarizable Ag/AgCl electrodes (Clark Electromedical Instruments, Ref. E243) placed on upper limb regions correponding where sympathetic innervation was spared by the neurological lesion. Isotonic conductive paste was used to improve skin/electrode contact. Skin resistance was recorded with 15 uA current (current density=0.5 uA/mm2).

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients were hospitalized after traumatic cervical spinal cord injury. The head medical doctor responsible for patient's hospitalization and medical care delivery checked that participants met the inclusion criteria, and informed of the possibility to participate in a rehabilitation research program. Participants provided written informed consent according to the statements and principles of the Declaration of Helsinki.
Healthy control participants matched according to genre and age to the patients also participated in the trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
SCI patients were systematically allocated to the treatment group. Healthy control participants matched according to genre and age to the patients were assigned to the control group.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Due to ethical reasons, we could not deprive voluntarily SCI patients from the treatment condition so as to constitute a patient control group. Indeed, there is a rich scientific background supporting the therapeutical relevance of motor imagery interventions in the management of motor rehabilitation in neurological populations.

Summary
Brief summary
Grasp function is severely impaired after quadriplegia elicited by traumatic spinal cord injury. Patients can learn a modified type of grasp called tenodesis, where pinch grip is generated by active wrist extension (a movement spared by the lesion below the C6-C7 level). We investigate whether mental training with motor imagery can improve tenodesis grasp function in quadriplegic patients. Using magnetoencephalography, we seek to delineate whether mental training can induce cerebral reorganizations enabling functional motor recovery. We also investigate whether the neural networks mediating motor imagery are reorganized due to motor rehabilitation with mental training.
