The use of Transcranial Magnetic Stimulation and Thermography in the examination of patients with Multiple Sclerosis

Summary
The majority of patients with Multiple Sclerosis have motor dysfunction from the early onset of the disease. Both acute presentations and subsequent relapses of the disease contribute to the worsening of the motor deficits that can develop into quadriplegia. Quantification of the deficits is performed using EDSS scale (1, 7) which can quantify the gait deficits among other parameters.
Aim. The present study looked at the variability of both cortical and peripheral latencies on a group of RRMS patients at rest and after exercise on an ergonomic bicycle.
Material and methods. Furthermore the thermography investigation was performed by looking at the tissue located in posterior lodge of the calf back before and after exercise.
Results. The results found were that the shortening of the cortical latency after completion of physical activities was associated with a low temperature of the tissue.
Conclusions. Physical therapy improves at least transiently the motor cortex excitability as well as the velocities of the nervous impulse. Heat loss can be related to partial involvement of the motor units in the muscle contraction but also to the exaggerated losses by altering the sympathetic tone (10, 12).
