- Abstract: Analyzing the electromyographic (EMG) activity accompanying motor imagery (MI) as well as the imagery-related effects on strength enhancement contributes to a better understanding of the neural mechanisms of MI. Accordingly, the subliminal EMG activity recorded during MI supports the hypothesis of an incomplete inhibition of the motor command during mental rehearsal. Interestingly, the pattern of EMG response was modulated by the mental effort and the imagined contraction type, in the same way as during physical movement. Furthermore, the data provided evidence that MI contributed both to increase muscle strength, though strength gains were not observed in all muscles. Finally, MI was found to facilitate motor recovery following anterior cruciate ligament tear as well as in burned patients. These results confirm that MI should be considered a reliable and cost-effective technique to improve motor recovery and motor performance.

Title : "Electromyographic recording during motor imagery. Effect of intensity and types of muscle contraction"

- Abstract: Motor imagery (MI) is defined as mental representation of movement with no body movement. A subliminal muscular activity is usually recorded during MI, the magnitude of activation being a fraction of that observed during actual performance. This activity, however, was not systematically reported as muscular quiescence was also observed during MI. Thirty sport students (15 males, 15 females) took part voluntarily to the experiment. They were required to perform and imagine an elbow flexion with weighted dumbbells. The four tested conditions were i) heavy concentric contraction (80% of 1 RM), ii) light concentric contraction (50% of 1 RM), iii) isometric contraction and iv) eccentric contraction (120% of 1 RM). Electromyographical (EMG) surface electrodes were used to record the activity of 2 agonist muscles (shot and court portions of the biceps brachii), 1 antagonist muscle (triceps brachii), 3 synergist muscles (brachioradialis, flexor carpi ulnaris and radialis) and 3 muscles with a tonic function (anterior deltoïdus, superior trapezius and major pectoralis). A goniometer was used to check the absence of any elbow movement during MI. Moreover, MI ability was estimated using the Revised version of the Movement Imagery Questionnaire and MI accuracy was evaluated through the analysis of the skin resistance responses. The magnitude of the EMG activity was found to be systematically greater during MI than during rest. Such an activity was also greater during the Conc-F condition than during the Conc-f condition. Moreover, the type of muscle contraction was found to influence the EMG activity during imagined performance: the EMG activity was significantly greater during Iso, Conc-F and Ecc conditions than during the Conc-f condition. However these results did not provide evidence of any relationship between MI accuracy and EMG activity. It is concluded that the residual EMG activity is a consequence of a central representation of the movement and may due to an incomplete inhibition of the motor command.
