Forty male and 40 female clients requesting counseling from a university counseling service were assigned to one of eight treatment conditions in a randomized 2X2X2 design to determine the effects of counselor status (high, low), counselor weight (normal, overweight), and client gender, on initial perceptions of counselor expertness, attractiveness, and trustworthiness. Clients viewed a brochure containing a photograph and description of either a high status normal weight, high status overweight, low status normal weight, or a low status overweight counselor and heard a precounseling audiotape explaining the counseling process. Clients then completed the Counselor Rating Form, used to measure the dependent variables. Multivariate analysis of variance yielded a significant main effect for status and effects approaching statistical significance for an interaction between counselor status and counselor weight on the variables of expertness and trustworthiness. No effects attributable to client gender were found. Results that support the effects of status on a client's initial impression of a counselor are discussed in terms of social influence theory. Implications for further research are noted.
Background: Intrathecal baclofen (ITB) is traditionally reserved for non-ambulatory patients. Objective: To investigate outcomes of ITB in ambulatory multiple sclerosis (MS) patients. Methods: Changes in outcome measures were estimated by a mixed effect model, while the complication rate was calculated using a logistic regression. Predictors of non-ambulatory status were identified by Cox model. Results: In all, 256 patients received an ITB test injection and 170 underwent ITB surgery. Aggregate Modified Ashworth Scale (MAS) scores for the ambulatory ITB cohort decreased from 13.5 ± 6.96 to 4.54 ± 4.18 at 5 years ( p < 0.001). There was no significant change in walking speed 1 year post ITB surgery (0.45 m/second ± 0.30 vs 0.38 m/second ± 0.39, p = 0.80) with 77.8% of patients remaining ambulatory which decreased to 41.7% at year 5. Longer MS disease duration (hazard ratio (HR): 1.04; 95% confidence interval (CI): 1.01–1.07; p = 0.018) and lower hip flexor strength (HR: 0.40; 95% CI: 0.27–0.57; p < 0.001) predicted non-ambulatory status after surgery. Complications were more likely in the ambulatory cohort (odds ratio (OR): 3.30, 95% CI: 2.17–5.02; p = 0.017). Conclusion: ITB is effective for ambulatory MS patients without compromising short-term walking speed, although a higher complication rate was observed in this cohort.
IntroductionIntrathecal baclofen (ITB) therapy is an effective way to manage spasticity in numerous conditions, including multiple sclerosis, stroke, and cerebral palsy. While pump failure is a common complication of ITB, improvements in device design have led to reduction of complications. In particular, the Ascenda catheter from Medtronic, Inc. was designed to resist kinking and associated complications; indeed, no incidences of catheter twisting or occlusion have been reported in literature prior to this case.Case ReportWe report a case of a 32-year old gentleman who presented to the clinic with symptoms of baclofen withdrawal 19 months after he had a programmable pump implanted for spasticity. During the diagnostic evaluation it was discovered that the patients pump had flipped in his abdominal pocket. He was taken to surgery to reorient the pump, during which time it was noted the catheter was tightly coiled on itself occluding flow. The twisted catheter was excised and replaced with a new segment.His symptoms subsequently resolved.ConclusionsAlthough catheter occlusions have subsided since the approval of the Ascenda catheter, pump twiddler’s syndrome remains a risk factor for this complication. This is the first report describing this syndrome in a patient with the Ascenda catheter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
