“…Historically, mirror therapy was the first rehabilitation technique used to offer patients subjective visual feedback of correct movement performed by a paretic limb [ 1 , 2 ]. In lower-limb mirror therapy, a mirror is placed between the subject’s legs; the subjects are invited to perform a movement with their healthy leg while observing the mirror’s reflection, which gives them the subjective illusion of moving their paretic leg.…”

Background Video-feedback observational therapy (VOT) is an intensive rehabilitation technique based on movement repetition and visualization that has shown benefits for motor rehabilitation of the upper and lower limbs. Despite an increase in recent literature on the neurophysiological effects of VOT in the upper limb, there is little knowledge about the cortical effects of visual feedback therapies when applied to the lower limbs. The aim of our study was to better understand the neurophysiological effects of VOT. Thus, we identified and compared the EEG biomarkers of healthy subjects undergoing lower limb VOT during three tasks: passive observation, observation and motor imagery, observation and motor execution. Methods We recruited 38 healthy volunteers and monitored their EEG activity while they performed a right ankle dorsiflexion task in the VOT. Three graded motor tasks associated with action observation were tested: action observation alone (O), motor imagery with action observation (OI), and motor execution synchronized with action observation (OM). The alpha and beta event-related desynchronization (ERD) and event-related synchronization (or beta rebound, ERS) rhythms were used as biomarkers of cortical activation and compared between conditions with a permutation test. Changes in connectivity during the task were computed with phase locking value (PLV). Results During the task, in the alpha band, the ERD was comparable between O and OI activities across the precentral, central and parietal electrodes. OM involved the same regions but had greater ERD over the central electrodes. In the beta band, there was a gradation of ERD intensity in O, OI and OM over central electrodes. After the task, the ERS changes were weak during the O task but were strong during the OI and OM (Cz) tasks, with no differences between OI and OM. Conclusion Alpha band ERD results demonstrated the recruitment of mirror neurons during lower limb VOT due to visual feedback. Beta band ERD reflects strong recruitment of the sensorimotor cortex evoked by motor imagery and action execution. These results also emphasize the need for an active motor task, either motor imagery or motor execution task during VOT, to elicit a post-task ERS, which is absent during passive observation.

Previous research on the interconnections between brain activity and actions had led to the discovery of mirror neurons, neurons that have two particularly important roles: they mediate the imitation of movements based on visual information, and they underlie the understanding of actions. Mirror therapy is a relatively new, non-invasive therapy based on the use of visual feedback in recovery. Since 1996, it has been introduced in medical rehabilitation programmes, targeting conditions such as: hemiplegia after stroke, gait recovery after stroke, improvement of finger coordination in Parkinson's patients, reduction of phantom limb pain after amputations, and chronic pain from hand osteoarthritis, fibromyalgia, and complex regional pain syndrome. The device that is the subject of the present work presents a new constructive variant of the mirror box, which offers a much more efficient method of applying mirror therapy in various conditions, both at the level of the upper and lower limbs. The results of two assessments on the effectiveness of visual stimulation in recovery, carried out with the help of this device, first on the recovery of the hand functionality in subjects with hemiparesis after ischemic stroke and second assessment in the treatment of chronic pain of subjects with hand osteoarthritis will also be presented.
