Multicenter StudyAssessment of functional improvement without compensation for human spinal cord injury: extending the Neuromuscular Recovery Scale to the upper extremities.
The Neuromuscular Recovery Scale (NRS) is a tool for measuring functional recovery in spinal cord injured (SCI) persons based on tasks that test pre-injury functional capability. The NRS has been shown to be a valid, reliable, and responsive instrument for measuring functional recovery. The NRS has been updated to include three items measuring upper extremity function, and a new scoring mechanism has been defined. ⋯ The NRS score was more strongly correlated with other SCI functional measures than ISNCSCI motor scores were. The new NRS score was most responsive to change brought on by locomotor training. The expanded NRS appears to be a valuable tool in measuring functional recovery from SCI; further evaluation of its psychometric properties is warranted.

Influence of previous comorbidities and common complications on motor function after early surgical treatment of patients with traumatic spinal cord injury.
The influence of complications and comorbidities on the outcome of patients with traumatic spinal cord injury after early surgery is unclear. The aim of the current study was to analyze the influence of previous comorbidities and common complications on motor function outcome of patients with traumatic spinal cord injury if early surgery was performed. All patients with a traumatic spinal cord injury who were initially surgically treated in our hospital in the period from January 2008 to December 2013 were included in this study. ⋯ The current study shows that motor function was able to be improved in patients who were given early surgery after a traumatic spinal cord injury. Common complications as well as previous cardiovascular, pulmonary, and metabolic comorbidities do not impair motor function outcome. The final motor function score is reduced if patients have previous spinal comorbidities.

The Evaluation of Magnesium Chloride within a Polyethylene Glycol Formulation in a Porcine Model of Acute Spinal Cord Injury.
A porcine model of spinal cord injury (SCI) was used to evaluate the neuroprotective effects of magnesium chloride (MgCl2) within a polyethylene glycol (PEG) formulation, called "AC105" (Acorda Therapeutics Inc., Ardsley, NY). Specifically, we tested the hypothesis that AC105 would lead to greater tissue sparing at the injury site and improved behavioral outcome when delivered in a clinically realistic time window post-injury. Four hours after contusion/compression injury, Yucatan minipigs were randomized to receive a 30-min intravenous infusion of AC105, magnesium sulfate (MgSO4), or saline. ⋯ Histological analysis revealed no significant increase in gray or white matter sparing with AC105 or MgSO4 treatment. Finally, AC105 did not result in higher Mg2+ levels in CSF than with the use of standard MgSO4. In summary, when testing AC105 in a porcine model of SCI, we were unable to reproduce the promising therapeutic benefits observed previously in less-severe rodent models of SCI.

Effectiveness of automated locomotor training in patients with acute incomplete spinal cord injury: A randomized controlled multicenter trial.
The aim of this study was to evaluate whether the effect of longer training times (50 instead of 25 min per day) using a robotic device results in a better outcome of walking ability of subjects with a subacute motor complete (American Spinal Injury Association Impairment Scale [AIS]-B) and incomplete (AIS-C) spinal cord injury. Twenty-one patients were enrolled in the study, whereof 18 completed, on average, 34 trainings in 8 weeks. ⋯ It has to remain open whether even longer training times (more than 50 min) would result in a still better outcome. In any case, the extent of possible recovery in an individual patient is determined by the level and severity of spinal cord damage.

Test or rest? Computerized cognitive testing in the emergency department after pediatric mild traumatic brain injury does not delay symptom recovery.
Rest is commonly prescribed following a mild traumatic brain injury (mTBI). There is concern that cognitive exertion by an acutely or sub-acutely injured brain may negatively alter outcome. The objective of this study was to determine if computerized cognitive testing in the emergency department alters symptom outcome from mTBI. ⋯ There also was no difference in symptom outcome for those who underwent a shortened (four subtests, mean time = 16 min) or full-length (seven subtests, mean time = 28 min) version of the computerized test. Brief cognitive exertion using a computerized cognitive assessment after mTBI in youth does not result in worse symptoms at these follow-up periods, does not prolong symptom recovery, should not be considered contraindicated to recovery, and could be considered as another tool to aid in the management of these injuries. Further research with different samples is warranted.
