Comparative Study
Patients with chronic neck pain demonstrate altered patterns of muscle activation during performance of a functional upper limb task.
Cross-sectional study. ⋯ Patients with neck pain demonstrated greater activation of accessory neck muscles during a repetitive upper limb task compared to asymptomatic controls. Greater activation of the cervical muscles in patients with neck pain may represent an altered pattern of motor control to compensate for reduced activation of painful muscles. Greater perceived disability among patients with neck pain accounted for the greater electromyographic amplitude of the superficial cervical muscles during performance of the functional task.

A 3-year prospective, cohort study. ⋯ Dysphagia is a common occurrence after AC procedures but was also found after PC procedures. Intubation alone was not a risk factor for postoperative dysphagia in this cohort.

Cross-sectional, population-based survey. ⋯ Young people are more likely to suffer from asthma and headache, but not from atopic dermatitis/hay fever, if they have low back pain. All of the investigated disorders cluster in some individuals. A model of common origin for these seemingly independent disorders should be considered.

A retrospective review with clinical and radiologic assessment was conducted. ⋯ Twenty-three patients with tuberculosis of the lower lumbar spine underwent posterior instrumentation with laminar hooks and anterior interbody arthrodesis by a single surgeon. The clinical outcomes were evaluated with preoperative and postoperative questionnaires, and the radiographs were independently analyzed with respect to fusion status and sagittal angle. RESULTS.: The mean follow-up period was 28.7 months (range, 24-39 months). The average preoperative, immediate postoperative, and final follow-up sagittal angles were 2.7 degrees, -14.1 degrees, and -11.5 degrees, respectively. There was a mean reduction of 16.7 degrees (range, 9 degrees-23 degrees) after surgery. Two patients had a correction loss more than 5 degrees during the follow-up period. Bony fusion was obtained in all patients. There was no recurrence of the disease. CONCLUSION.: This technique appears to be effective in stabilizing the vertebrae, restoring lordosis, achieving a solid fusion, and improving clinical outcome without sacrificing additional motion segments.
