- Cystic lesions of the spinal cord (syringomyelia) may occur after spinal cord injury. Posttraumatic syringomyelia may result in a myelopathy causing symptoms of sensory and motor loss, as well as worsening spasticity, pain, hyperhidrosis, and autonomic dysreflexia. Shunting of the cyst cavity along with untethering of the scarred spinal cord is widely accepted as the treatment of choice. However, the long-term stabilization of the progressive myelopathy caused by a posttraumatic cyst is suboptimal because of arachnoidal rescarring, shunt tube blockage, and cyst reexpansion. A new neurosurgical strategy to overcome the complication of cyst reexpansion was designed. Experimental studies have shown the successful use of embryonic spinal cord grafts, including human grafts, to obliterate induced spinal cord cavities in rats. The authors report the first use of solid human embryonic spinal cord grafts to successfully obliterate 6 cm of a large cyst cavity in a patient becoming myelopathic from a posttraumatic cyst. The grafts are well visualized by MRI to the 7-month postoperative follow-up and cyst obliteration is seen in the region where the grafts were placed.

- STUDY DESIGN: Out of a population of 456 patients with spinal cord injuries (SCI), 130 having pain were selected after matching, based on gender, age, American Spinal Injury Association (ASIA) impairment grade and level of lesion.OBJECTIVE: To investigate whether gender differences with regard to pain perception and prevalence exist in a population of patients following spinal cord injury.SETTING: Spinalis SCI Unit (out-patient clinic), Stockholm, Sweden.METHOD: 130 patients suffering from pain were assessed over a 12-month period in a yearly health control.RESULTS: SCI women had a higher prevalence of nociceptive pain than men and their use of analgesics was greater. However, no differences between the sexes could be seen regarding pain and localization, onset, distribution, factors affecting pain, number of painful body regions, pain descriptors, ratings of pain intensities or in pain and life satisfaction.CONCLUSION: This study showed that SCI men and women describe their pain very similarly. However, SCI women had a higher prevalence of nociceptive pain than men and their use of opiates and non-steroid anti-inflammatory drugs (NSAIDs) was greater.

- OBJECTIVE: A recent prevalence study of 353 spinal cord injured (SCI) individuals in the greater Stockholm area showed problematic spasticity in 30% of this population. To treat spasticity, the evaluation becomes crucial. The modified Ashworth scale (MAS) is the clinically most-used scale to grade degree of spasticity. This study evaluated whether the MAS correlated with electromyographic (EMG) recordings of muscle activity.STUDY DESIGN: This cross-sectional study was performed at an outpatient clinic that has the responsibility to do a standardized, yearly follow-up of all SCI patients in the greater Stockholm area. Thirty-eight SCI individuals met the inclusion criteria; 15 of the 38 were randomly selected for the study. They were all motor-complete tetraplegic men; mean age was 33 years and mean time since injury was 9 years. Spasticity evaluation was performed by flexing and extending the knees during simultaneous EMG recordings and MAS assessment of the thigh muscle activity.RESULTS: Eighty percent of the individual EMG recordings correlated significantly with the corresponding Ashworth measurements. The spastic resistance, as measured both clinically and electromyographically, was stronger and lasted longer during extension than flexion movements. Spearman coefficients for correlation of quantitative spasticity measures with MAS grades were calculated. EMG and clinical measures of spasticity were more closely correlated for flexion movements. Among EMG parameters, duration of movement-associated electrical activity invariably correlated significantly with the MAS grades (p < .05). Furthermore, Ashworth measurements of movement-associated spasticity showed a positive correlation with the EMG parameters mean, peak, and start to peak of electrical activity. Each increasing grade on the MAS corresponded to increasing myoelectric activity levels for each movement.CONCLUSION: EMG parameters were significantly positively correlated with simultaneous MAS measurements of the spastic muscle contraction. The Ashworth scale may therefore accurately reflect the movement-provoked spasticity in motor-complete tetraplegic patients.
