Scoliosis Patients (scoliosis + patient)
Selected AbstractsElectromyography of scoliotic patients treated with a braceJOURNAL OF ORTHOPAEDIC RESEARCH, Issue 5 2003Daniel Odermatt Abstract When a brace is used to correct spinal deviation, patients may seek to ease the discomfort from the pressure exerted by the orthosis by actively recruiting specific trunk muscles. The effect of bracing on trunk electromyography (EMG) has been reported in only one study where a limited number of electrodes were placed mainly in the thoracic region. Our hypothesis was that a multi-electrode mapping of the activity of the thoracic, lumbar, and abdominal trunk muscles would provide a more representative picture of the muscular reaction in response to bracing. With a larger number of EMG measuring sites, the presence of any brace-induced trunk muscle activity should be detected. Therefore, EMG signals of 11 adolescent idiopathic scoliosis patients who had been undergoing Boston brace treatment for 0.7-3 years were collected during four isometric tasks to evaluate the response of trunk muscles in the minutes following the application of the brace. Twenty-two pairs of bipolar electrodes were used to measure the EMG signals of the main superficial trunk muscles during four isometric tasks. EMG signals of trunk muscles were compared in braced and unbraced conditions. Brace-induced increases in EMG activity were significant in 43% of the individual measurements and in three of the four tasks for the group mean values. Increases were greater in the lumbar area, especially on the convex side of the secondary (lumbar) curve. These results thus suggest that immediately following the application of the brace, significant muscular responses can be observed in some patients. © 2003 Orthopaedic Research Society.

Although epidural (EP) analgesia represents the most effective way to provide adequate analgesia after thoracotomy, scoliosis patients have substantial anatomic variations that make EP catheter placement more difficult and often contraindicated. This case report describes a safe, effective technique for placing a thoracic EP catheter in a young patient undergoing anterior spine fusion surgery by thoracotomy. The procedure was guided by both ultrasound (US) and electrical stimulation of the Tuohy needle and catheter. The combination of US and nerve stimulation in this setting may be associated with easier, potentially safer, and more accurate insertion.

Methods:, We examined the NMJs of four children, age 6,13 years, who were diagnosed with DMD. Using our previously established staining technique, we examined the gross appearance of the NMJs in patients with DMD and evaluated the spread of acetylcholine receptors (AChRs) in relationship to the NMJs. We used a computerized algorithm to measure the area of staining corresponding to AChRs and NMJ. Results:, Abnormal shape and morphological appearance of some of the NMJs was clearly evident. The spread of AChRs in DMD patients is comparable with the spread of AChRs in nonDMD patients. Conclusions:, The distribution of AChRs in relationship to the boundaries of NMJs in DMD children is similar to the distribution of NMJs in the erector spinae muscles of idiopathic scoliosis patients.
