Drs. O. L. Kim and S. H. Kim of the College of Medicine, Yeungnam University, Taegu, Korea write in the  November 14,

 2011 issue of Archives of  Neurology about the fact that many studies have attempted to review the causes of motor weakness in patients with traumatic brain injury (TBI). Most of these studies however have focused on the specific cause of the motor weakness. However, the classification and elucidation of the causes of motor weakness in consecutive patients with TBI is still not fully understood.
Diffusion tensor imaging has been used to attempt to classify the causes of motor weakness in TBI patient. This is done by analyzing the injury mechanism of the corticospinal tract (CST)s
The setting for the study was the rehabilitation department of a university hospital.
41 consecutive  admitted patients with TBI that showed motor weakness were enrolled.
The injury mechanisms of the CST  were classified and linked to the motor weakness.
1. Diffuse axonal injury –  24 patients (58.5%) CST . Injury locations – pons (61%)/ cerebral peduncle (50%)/ medulla (40%) posterior limb of the internal capsule (17%)/ corona radiata (13%).
2. Traumatic intracerebral hemorrhage (9 patients) – (21.9%)
3. Transtentorial herniation – 6 patients (14.6%)
4. Focal cortical contusion –  4 patients (9.8%
The group concluded that diffusion tensor imaging helped in elucidation and classification of the causes of motor weakness that were seen to result from CST injury in TBI.
When the Tutor system enters the “rehabilitation picture” the potential results are markedly improved. Used for SCI as well as brain injury, Parkinson’s disease, MS, CP, stoke, upper and lower extremity surgeries, Radial and Ulnar nerve injuries, Complex Regional Pain Syndrome and other disabilities the Tutor system implements an impairment based rehabilitation program with augmented feedback and encourages motor learning through intensive active exercises.
The newly developed Tutors and its component devices (HandTutor, ArmTutor, LegTutor, 3DTutor) have become a key system in neuromuscular rehabilitation and physical therapy.  These exercises are challenging and motivating and allow for repetitive training tailored to the patient’s performance and movement ability. The Tutor system also includes objective quantitative evaluations that allow the therapist to document and report on the patients improvement and ti further customize the rehabilitation software to the most suitable rehabilitation program for the patient’s sensory motor and cognitive ability. Currently part of the rehabilitation program of leading U.S. and foreign hospitals the Tutors (consisting of HandTutor ArmTutor and LegTutor) are also used in clinics and at home through the use of telerehabilitation (TR). The Tutors are suitable for children as well as adults. See http://www.HandTutor.com
