Research summary
Can an Actigraph GT3X accelerometer, placed at the thigh or ankle of the same leg, accurately measure body position and walking episodes undertaken by patients recovering from critical illness in a hospital ward?\n\nEvidence suggests patients recovering from critical illness on a hospital ward are spending large proportions of the day inactive, even in the last few days of their stay. This is concerning, considering the limited access to specialist rehabilitation services in the UK post discharge and reports of continued functional limitation being experienced years following illness. Increased attention should be given to monitoring activity levels, especially during the last few days of hospital stay, identifying those who may need more help and support to increase independence. \n\nActivity could be monitored using direct observation or patient self-report. Both these methods encounter difficulties however, including resource intensity for observation or problems with accuracy of recall, especially in populations who may experience cognitive impairment. Activity monitors have the potential to identify activity undertaken on a ward; without compromising privacy or dignity. They could also identify prolonged periods of inactivity, assisting in the effective allocation of rehabilitation resources, whilst providing objective feedback for patients on their own activity levels. \n\nThis study aims to investigate whether a particular model of commercial activity monitor (an Actigraph GT3X accelerometer) can identify typical activities undertaken by patients recovering from critical illness. This unfunded prospective observational study will invite patients progressing in their recovery on a hospital ward to participate, completing a semi structured movement protocol. Participants will wear one Actigraph GT3X accelerometer on the thigh and another on the ankle of the same leg. Data captured by the accelerometers will be compared against direct observation.
