Data confirming the hypothesis that there is a range of isometric loads where subjects organize voluntary control of muscle tension with the maximum precision and minimum specific energy expenditure are presented, the energy expenditure being estimated indirectly by the ratio of the area (integral) of the summary electromyogram (EMG) to the force momentum impulse. The asymmetries of the integrated estimates of visuomotor tracking with the use of isometric control organs have been analyzed in 23 patients (6 men and 17 women) aged 15-35 years in different periods, after surgical elimination of the difference between the lengths of their lower extremities. A slightly distinct zone of minimization of the integrated estimates of discrete visuomotor tracking in the range of 25-35% of the maximum force of the muscle group tested (foot dorsal flexors) has been found in healthy subjects (26 healthy men aged 19-39 years) and orthopedic patients (the intact extremity). The zone of optimal loads is more distinct in patents on the side of lengthening; this zone tends to shift towards the region of weaker forces. © 2012 Pleiades Publishing, Ltd. Source

Electroneuromyography (ENMG) was used to assess the effectiveness of a short combined neurorehabilitation course (temporal epidural stimulation of the spinal cord combined with robotic kinesiotherapy) in the restorative treatment of patients with traumatic spinal cord disease. Before and after the combined instrumental neurorehabilitation course (the duration was from two to three weeks), 75 patients suffering from consequences of the spinal cord injury were tested. Global and stimulation (H-reflex, M-response) electromyography methods were used. On the basis of the ENMG data, the indices of sensorimotor deficit (ISD) and their postrehabilitation trends were calculated. The ENMG signs of regression of sensorimotor deficit in the lower extremities were observed in 46.6% of the cases; those in the upper extremities (if the cervical spine was damaged) were found in 78.6% of the cases. The stabilizing effect of the neurorehabilitation technique used was observed in an average of 24.0% of the cases. In 18.8% of the cases, the use of the combined neurorehabilitation technique was ineffective. The indications for the use of the combined neurorehabilitation course series should include the ENMG signs of the partial preservation of the corticospinal tract conduction and a positive ISD trend after completion of each course. © 2015, Pleiades Publishing, Inc.

According to published reports, an incomplete restoration of the muscular strength is observed after malleolar fractures. This made us evaluate the contractile capacity of the tibial muscles after treatment of 59 adult patients with malleolar fractures using Ilizarov’s method. In addition, five patients underwent comprehensive follow-up examinations long after fracture treatment. We found that a practically complete restoration of the anatomical size, electrogenesis, and contractile property of the tibial muscles was possible in the interval from five to eight years after treatment. This can be explained by a precise repositioning and reliable fixation of the bone fragments during treatment and an increase in the sensitivity of the neuromotor responses to specific impacts during muscle adaptation to function under conditions of habitual motor activity. © 2015, Pleiades Publishing, Inc.
