This study investigated the efficacy of guidelines for a motivated class teacher to enhance the application of back care principles, taught by a physical therapist, in fifth-grade elementary schoolchildren. Testing consisted of a practical test before and a practical test, knowledge test and candid camera evaluation 11 weeks after the program. Three groups were compared: an intervention group of 38 pupils, with extra guidelines for the teacher, an intervention group of 48 pupils, without extra guidelines and 34 controls. The intervention plus guidelines group, compared to the intervention group without extra teacher guidelines, obtained significantly higher posttest-pretest gain scores for five of the seven practical test items and scored significantly higher for seven of the nine items of the candid camera evaluation. Knowledge test scores did not differ significantly between the two intervention groups. Study results indicate that guidelines to a motivated class teacher improve efficacy of back care education in elementary schoolchildren.
BACKGROUND AND PURPOSE: Several prognostic factors have been identified for outcome after stroke. However, there is a need for empirically derived models that can predict outcome and assist in medical management during rehabilitation. To be useful, these models should take into account early changes in recovery and individual patient characteristics. We present such a model and demonstrate its clinical utility. METHODS: Data on functional recovery (Barthel Index) at 0, 2, 4, 6, and 12 months after stroke were collected prospectively for 299 stroke patients at 2 London hospitals. Multilevel models were used to model recovery trajectories, allowing for day-to-day and between-patient variation. The predictive performance of the model was validated with an independent cohort of 710 stroke patients. RESULTS: Urinary incontinence, sex, prestroke disability, and dysarthria affected the level of outcome after stroke; age, dysphasia, and limb deficit also affected the rate of recovery. Applying this to the validation cohort, the average difference between predicted and observed Barthel Index was -0.4, with 90% limits of agreement from -7 to 6. Predicted Barthel Index lay within 3 points of the observed Barthel Index on 49% of occasions and improved to 69% when patients' recovery histories were taken into account. CONCLUSIONS: The model predicts recovery at various stages of rehabilitation in ways that could improve clinical decision making. Predictions can be altered in light of observed recovery. This model is a potentially useful tool for comparing individual patients with average recovery trajectories. Patients at elevated risk could be identified and interventions initiated.
BACKGROUND: The recent randomized, controlled trial of interferon-beta1b (IFN-beta1b) in 718 patients with secondary progressive MS (SP-MS) demonstrated a significant effect on the development of disability as evaluated by the physician. Its effect on patient-reported health-related quality of life (HrQoL) is reported herein. METHODS: In this multicenter, double-blind, randomized, placebo-controlled trial, outpatients with SP-MS scoring between 3.0 and 6.5 on the Expanded Disability Status Scale received either 8 x 10(6) IU of IFN-beta1b or placebo for up to 3 years. A range of outcomes was measured, including HrQoL, which was assessed using the Sickness Impact Profile (SIP), a self-report questionnaire validated for use in MS. Measurements were undertaken at baseline and at 6-monthly intervals thereafter for 36 months. RESULTS: A slight positive effect on the HrQoL of the IFN group in comparison with the placebo group was found, which reached significance in the physical scale of the SIP at 6 and 12 months and at last visit. There was moderate correlation between physician-assessed evaluation of change and patient-reported change. CONCLUSIONS: IFN-beta1b may delay sustained deterioration in patient-reported HrQoL in SP-MS. Methods of interpreting change in HrQoL are currently insufficiently developed to determine how clinically important these changes are for this population.
