Efficacy of Virtual Reality in Upper Limb Rehabilitation in Patients with Spinal Cord Injury: A Pilot Randomized Controlled Trial

STUDY DESIGN: Pilot randomized controlled trial. PURPOSE: To compare the efficacy between virtual reality intervention (using Nintendo Wii) along with conventional occupational therapy and conventional occupational therapy alone in improving upper limb function in patients with spinal cord injury (SCI). OVERVIEW OF LITERATURE: The use of virtual reality has gained importance in the rehabilitation sector over the last few years. Nintendo Wii has the potential to encourage upper limb function while engaging in an interesting activity, which is important in long-term interventions, such as the treatment of SCI. METHODS: Overall, 22 patients with SCI participated in the study. They were randomly assigned to two groups. Group I received 30 minutes of virtual reality intervention (using Nintendo Wii) and 30 minutes of conventional therapy, whereas group II received conventional therapy only for 30 minutes. Both groups received therapy 3 days a week for 4 weeks. One hand of each patient was identified as the target hand based on the inclusion criteria. All patients were assessed at baseline, 2 weeks and 4 weeks (post-intervention), and 6 weeks (follow-up). The functional ability of the target hand was assessed using the Capabilities of Upper Extremity (CUE) questionnaire. Gross motor dexterity was assessed using the Box and Block Test (BBT). The level of independence in activities of daily living was assessed by the Spinal Cord Independence Measure-Self Report and quality of life by the World Health Organization Quality of Life-BREF. RESULTS: After 4 weeks of intervention, there was no significant difference in improved hand function between the groups. Mean scores were higher for group I than for group II, with a higher percent change (31.5% in CUE questionnaire and 51.7% in BBT) in group I. CONCLUSIONS: Virtual reality along with conventional therapy produces similar results in upper limb function as does conventional therapy alone.

Prediction of mortality and morbidity by simplified acute physiology score II in obstetric intensive care unit admissions.

BACKGROUND: Critical care in obstetrics has received much attention in recent times. Despite progress in medical field and improvement in health facilities provided, maternal mortality is still very high in most of the developing countries. AIM: To study and analyze records of patients requiring intensive care in obstetrics and to assess utility of simplified acute physiology score (SAPS II) for predicting maternal mortality. SETTING: A multidisciplinary intensive care unit (ICU) at a tertiary care center. DESIGN: Retrospective review. MATERIALS AND METHODS: Fifty-seven consecutive obstetric patients' records requiring ICU admissions were studied for clinical picture, diagnosis, complications, morbidity and mortality over a period of 21/2 years - from 1st May 2002 to 31st Oct. 2004. SAPS II score was calculated according to the different variables for predicting mortality. STATISTICAL ANALYSIS: SAPS II scores were regressed on mortality status using logistic regression analysis. The predictability was assessed by goodness-of-fit test and receiver operated characteristic curve. RESULTS: Maternal mortality in obstetric ICU admissions was 1.15/1,000 deliveries, amounting to 40.35% of obstetric ICU admissions. The mean SAP II score was significantly higher (40.04 +/- 12.97 vs. 22.6 +/- 7.31) in those patients who died compared to survivors (P < 0.001%). CONCLUSIONS: The SAPS II accurately predicted mortality in obstetric patients admitted to ICU. Computation of the score as a routine in ICU may help in identifying those at high risk of mortality and then to reduce this risk.
