“…A MI has therefore been widely used for training purposes, with sportsmen and musicians [Hall et al 1998, Hall 2001, Langheim et al 2002, Lotze and Halsbrand 2006, Guillot et al 2010a, and in the rehabilitation of patients who cannot perform active movements following stroke, spinal cord injury (SCI) or chronic intractable pain [Moseley 2004, Butler and Page 2006, Mulder 2007, Page et al 2009, Grangeon et al 2010, Malouin 2010. In these studies patients were verbally guided to imagine some functional, object oriented task for which they could not produce a satisfactory overt movement, such as reaching or grasping an object.…”

“…In these studies patients were verbally guided to imagine some functional, object oriented task for which they could not produce a satisfactory overt movement, such as reaching or grasping an object. Patients achieved decreased reaching time, enhanced smoothness of a hand trajectory of their overt movements [Grangeon et al 2010], increased Fugl-Meyer score and results of the Action Research Arm (ARA) test [Page et al 2006] .…”

“…Although it is premature to draw final conclusion, and though we did not investigate the effects of imagery in patients, the present findings suggest that mirror imagery might be a valuable technique to acquire new motor coordination patterns. Such hypothesis is waiting for experimental investigation, but has received support from a recent study where a patient with spinal cord injury benefited from MI practice after a surgical procedure alleviating the paralysis of the triceps by transferring the distal insertion of either the deltoid or biceps brachii onto the triceps tendon (Grangeon, Guillot, Sancho, Picot, Revol, Rode, & Collet, 2010). Determining how MI affects the acquisition of mirror reversal patterns of movements will be an exciting focus of research in the coming years.…”

Physical practice is known to enhance motor adaptation skills, which refer to the individual ability to compensate for environmental changes. So far, it is still unknown whether a similar effect can be observed following motor imagery (MI). Thirty-nine participants were tested during a joystick tracking task under both normal and mirror conditions (i.e., the inductive direction of the joystick was reversed), before and after a physical practice or MI training phase. Eye movements and electromyographic activity were recorded during MI. Motor performance was also evaluated after a 6 h interval during daytime. As compared to the control group, the results revealed that both MI and physical practice improved motor performance in the mirror condition, during the posttraining test. Furthermore, the time to complete the task was further reduced after 6 hours, both in the normal and mirror conditions. These results demonstrate the effectiveness of MI for learning mirror-reversed movements, and for the consolidation process that follows motor adaptation.

“…SCI subjects also appeared to benefit from MI training programs to learn motor sequences executed with intact muscles (Cramer et al 2007). In clinical settings, single-case pilot experiments yielded that MI practice could improve the tenodesis prehension, i.e., increased movement speed and smoother hand trajectories were reported (Grangeon et al 2012(Grangeon et al , 2010. The authors inferred an effect of the technique on brain neuroplasticity, which was recently evidenced using magnetoencephalography (MEG) (Di Rienzo et al 2014b).…”

Motor imagery (MI - i.e., the mental representation of an action without physically executing it) stimulates brain motor networks and promotes motor learning after spinal cord injury (SCI). An interesting issue is whether the brain networks controlling MI are being reorganized with reference to spared motor functions. In this pilot study, we tested using magnetoencephalography (MEG) whether changes in cortical recruitment during MI were related to the motor changes elicited by rehabilitation. Over a 1-year period of inclusion, C6 SCI participants (n = 4) met stringent criteria for inclusion in a rehabilitation program focused on the tenodesis prehension (i.e., a compensatory prehension enabling seizing of objects in spite of hand and forearm muscles paralysis). After an extended baseline period of 5 weeks including repeated MEG and chronometric assessments of motor performance, MI training was embedded to the classical course of physiotherapy for five additional weeks. Posttest MEG and motor performance data were collected. A group of matched healthy control participants underwent a similar procedure. The MI intervention resulted in changes in the variability of the wrist extensions, i.e., a key movement of the tenodesis grasp (p < .05). Interestingly, the extent of cortical recruitment, quantified by the number of MEG activation sources recorded within Brodmann areas 1-8 during MI of the wrist extension, significantly predicted actual movement variability changes across sessions (p < .001). However, no such relationship was present for movement times. Repeated measurements afforded a reliable statistical power (range .70-.97). This pilot study does not provide straightforward evidence of MI efficacy, which would require a randomized controlled trial. Nonetheless, the data showed that the relationship between action and imagery of spared actions may be preserved after SCI.
