The high prevalence of persistent neck pain due to involvement of cervical facet joints has been described in controlled studies. Therapeutic interventions utilized in managing chronic neck pain of facet joint origin include intraarticular injections, medial branch nerve blocks, and neurolysis of medial branch nerves by means of radiofrequency. ⋯ Cervical medial branch blocks were an effective modality of treatment in managing chronic neck pain secondary to facet joint involvement confirmed by controlled, comparative local anesthetic blocks.

Lumbar transforaminal epidural injections have been utilized in the treatment of radicular pain with proven success. It was postulated that interlaminar epidural injections result in a dorsal flow of contrast while transforaminal epidural steroid injections showed good ventral flow limited to one single spinal motion segment. There have been no published studies evaluating epidurography/contrast patterns utilizing fluoroscopy. ⋯ Contrast appeared ventrally and unilaterally in all injections. Dorsal flow occurred in 20% of these injections. No contrast flow crossed the midline. The observed contrast flow patterns should be studied clinically to determine whether they have any effect on clinical outcome. Intravascular injections were noted in 10% of cases.

Results from a clinical evaluation of Functional Electrical Therapy (FET) in chronic hemiplegic subjects are presented. FET is an intensive exercise that integrates voluntary maximized manipulation and augmented grasping by electrical stimulation of forearm and hand muscles. A total of 16 chronic hemiplegic subjects participated in a six-month long study. ⋯ The trends of UEFT and DT scores during the therapy (three weeks) were steeper when compared with the trend during follow-up (23 weeks). The changes of the trends during the study suggest that prolonged treatment could lead to bigger gains. We found standard deviations were increased towards the end of follow-up suggesting individual differences in response to either the treatment or the disablement process.

Deep Brain Stimulation is an effective treatment of generalized dystonia. Optimal stimulation parameters vary between patients. This article investigates the influence of electrical brain impedance and delivered current on the brain response to stimulation. ⋯ The absolute impedance did not significantly correlate with the final outcome. We conclude that the reversible decrease of impedance reflects an adaptive long-term mechanism, which could be due to a plasticity phenomenon, but has no prognostic value. Impedance and current measurements give new complementary information for parameter adjustment and trouble shooting and should therefore be included in all patients' follow-up.

Specific search criteria identified 600 articles for review, of which 24 met inclusion and exclusion criteria: 2 in group 2, 3 in group 3, 14 in group 4, and 5 in group 4. A total of 1172 patients were represented (surgical treatment = 833, mean = 43.7 months' follow-up; conservative treatment = 339, mean = 60.4 months' follow-up). Both surgically and conservatively treated patients reported similar overall satisfactory outcome (88% surgical versus 87% conservative). Patients with surgical treatment reported longer time to return to work and premorbid activities. Among patients treated surgically, 59% had additional surgery, 6% had wound breakdown, 20% had fixation failure, and 3% reported residual deformity. Only 1% of conservatively treated patients reported wound problems, 6% had additional surgery, and 37% reported residual deformity. In only 1 study did the authors report the incidence of posttraumatic arthritis: 25% among surgically treated and 43% among conservatively treated patients. Analysis of secondary outcomes suggests that both groups had little or no pain (93% surgical, 96% conservative) but more conservatively treated patients had normal to near-normal range of motion (95% versus 86%) and normal strength (92% versus 87%). Conservative treatment of AC dislocations is 21% more likely to result in a satisfactory outcome than surgical treatment (odds ratio = 0.79, 95% confidence interval = 0.36, 1.71). The need for additional surgery is 7.4 times more likely and infection is 3.2 times more likely with surgical management. ⋯ These data suggest that the current evidence does not support surgical treatment of grade III AC dislocations with respect to overall patient satisfaction as well as clinical outcomes such as pain, range of motion, and strength.
