In one study involving people with dementia, five of the 11 participants stopped using the GPS device because it was too heavy, uncomfortable, or awkward to use, or they did not want to be tracked.

Р”Р„dditional problems with GPS technology have been reported, including limited battery life and time required by researchers to download and analyse hours of electronic data.

Contextual information can also be collected, such as the time and frequency of visits, providing important insights into a personРІР‚в„ўs weekly or monthly routine. Potential benefits of using a GPS device in health research include the provision of objective and accurate information about time, distance, and place. The device was valid and feasible for measuring distance walked in local streets, potentially removing the need for therapists to use a measuring wheel during an escorted trip. A GPS device was also used recently to measure distance walked outdoors by people with stroke during the 6-minute walk test while supervised by a therapist. GPS technology has been used in health research to track the position of children and older adults with dementia who wander. If the signal is blocked by dense urban development with narrow streets, close buildings, urban РІР‚СљcanyonsРІР‚Сњ or large objects, the accuracy of the GPS may be degraded or the signal not received at all. A GPS device can measure active transport and movement patterns in outdoor areas, but requires an unobstructed line of sight to the sky. A minimum of four satellites are required to estimate the position and elevation of the receiver. The location is identified by calculating the difference in time between when a satellite signal was sent and received. In contrast, wearable tracking devices such as global positioning systems (GPS) have the potential to give specific information about the timing and location of outings.Р”Р„ GPS device receives triangulated signals from satellites orbiting the earth. However, these devices do not adequately measure outings because they do not record where an outdoor activity occurred or its duration. Accelerometers are increasingly being used to measure physical activity with adult populations, including people with stroke.

Wearable sensors are emerging as a potential method of remotely monitoring and objectively measuring participation. Р”В¬ollecting information about outings can provide a picture of someoneРІР‚в„ўs ability to get out of their house and into the local community. Diaries capture minor events and produce higher РІР‚СљincidenceРІР‚Сњ rates, especially for healthy unimpaired populations however, diaries can also underreport events and lead to lower compliance by people with disabling conditions when compared to retrospective interviews. When retrospective interviews about events were compared with daily diary recordings of events, fewer recall errors were seen in the diary. Yet diaries produce unreliable data and are burdensome for participants, especially those with impaired cognitive abilities. Self-report diaries are a simple and cheap method of measuring physical activity. In addition, the process of observation may influence a personРІР‚в„ўs behaviour. The criterion standard method is direct observation, which is objective but time-consuming and costly. While the measurement of participation is increasingly common in health research, the measurement process remains challenging. The РІР‚СљamountРІР‚Сњ and РІР‚СљtypeРІР‚Сњ of community participation, such as outings, can be quantified, providing valuable information about changes over time due to intervention. IntroductionР”В¬ommunity participation is an objective indicator of the success and outcome of stroke rehabilitation. Simultaneous use of GPS and diaries is recommended for comprehensive analysis of outings. The GPS device and diary were both feasible and valid for measuring outings after stroke. PEA with observation was high for number of outings (GPS 94% diary 89%) but lower for purpose of outings (GPS 71% diary 82%). Data extraction took an average of 5 hours per participant. Some participants had difficulty operating the on/off switch and reading the small screen. Of 23 eligible participants, 20 consented (mean 3.6 years after stroke). Percent exact agreement (PEA) with observation was calculated for GPS and diary.

GPS data were analysed against Google maps. We recorded recruitment rate, user perceptions, and data extraction time.

Twenty ambulant people with stroke wore a GPS device and kept a diary for 7 days, and 18 were observed for half a day. This study aimed to investigate the feasibility and validity of a global positioning system (GPS) for measuring outings after stroke. Self-report diaries are a low-cost method of measuring community participation but may be inaccurate, while the РІР‚Сљgold standard,РІР‚Сњ observation is time consuming and costly.
