Time use and physical activity in a specialised brain injury rehabilitation unit: an observational study

Abstract

OBJECTIVES: To determine what is the use of time and physical activity in people undertaking inpatient rehabilitation in a specialised brain injury unit. To determine participants' level of independence related to the use of time and physical activity. METHODS: Design: Cross-sectional observation study. PARTICIPANTS: Fourteen people [mean (SD) age 40 (15) years] with brain injuries undertaking inpatient rehabilitation. PROCEDURE: Participants were observed every 12 minutes over 5 days (Monday to Friday from 7:30 am until 7:30 pm) using a behaviour mapping tool. OUTCOME MEASURES: Observation of location, people present, body position and activity engaged in (both therapeutic and nontherapeutic). Functional Independence Measure (FIM) scores were determined for each participant. RESULTS: Participants spent a large part of their time alone (34%) in sedentary positions (83%) and in their bedrooms (48%) doing non-therapeutic activities (78%). There was a positive relationship between a higher level of independence (higher FIM score) and being observed in active body positions (r=0.60; p=0.03) and participating in physically active therapeutic activities (r=0.53; p=0.05). CONCLUSION: Similar to stroke units, inpatients in a specialised brain injury unit spend large parts of the day sedentary, alone and doing non-therapeutic activities. Strategies need to be evaluated to address this problem, particularly for people with greater physical dependence.
