“…4,8 A series of reports based on studies of activity evaluation devices in wheelchair-using persons after SCI has been published in recent years. [9][10][11][12][13][14][15] Coulter et al 9 and Sonenblum et al 10,11 conducted several studies using multiaxial or triaxial accelerometers mounted on the wheels of wheelchairs. However, if the work involves mainly tasks using active muscles in the upper limbs, conducting an evaluation of physical activity using devices reflecting the movements of the upper limbs would be both legitimate and rational.…”

Objective: This study aimed to examine whether, on the basis of the relationship between sensors attached on the upper limbs and energy expenditure (EE) at the time of wheelchair propulsion, there are differences in the measurement of EE depending on the sensor attachment site and whether addition of the angular velocity information to the acceleration value is advantageous. We also aimed to clarify the variables used to estimate EE as well as the estimated error. Setting: Laboratory of the National Hospital Organization Murayama Medical Center, Japan. Methods: Six male subjects with spinal cord injuries participated in the study. Each wore sensors at the wrist and the middle upper arm on both sides while driving a wheelchair on a treadmill at three levels: very, very light; very light; and fairly light. Triaxial acceleration, triaxial angular velocity and EE were measured during driving. We analyzed the correlation between EE and acceleration, angular velocity and synthesized values of acceleration and angular velocity at each location using regression, multiple regression and Bland-Altman analyses. INTRODUCTIONIndividuals with spinal cord injury (SCI) are prone to disuse syndrome due to their injury and limited movement. Compared with healthy people, people with SCI are at higher risk for lifestylerelated diseases and metabolic syndrome. 1 Thus, to improve and maintain health, a plan for managing physical activity is necessary. 2,3 A recent prospective cohort study showed that an increased physical activity level is associated with both improved physical fitness and a reduced risk of developing cardiovascular diseases. 3 Devices are needed to assess physical activity and evaluate the efficacy of health-promotion interventions.It is difficult to assess daily physical activity in community-dwelling people according to measurements of energy expenditure (EE) using criterion methods such as calorimetry or doubly labeled water techniques. Therefore, the development and validation of wearable monitors such as pedometers, load transducers/foot-contact monitors, accelerometers, heart rate monitors, combined accelerometer and heart rate monitors and multiple sensor systems that enable the evaluation of physical activity in healthy individuals are in progress. 4

“…Research has shown that wheel rotation monitors can be used to assess mobility characteristics, activity levels, and wheelchair use of MWUs in laboratory, community and nursing home settings. [1][2][3][4] However, there are only a limited number of monitoring tools available for manual wheelchair users (MWUs). [2][3][4][5][6] This is especially striking as the general population can choose from a wide array of activity monitors to track their activities in the community in terms of steps, intensity of PA, duration of PA, and energy expenditure.…”

“…12,13 The existing measurement tools for MWUs have varying sensitivity and accuracy in estimating speeds and distances traveled by wheelchair users. These tools either use a pendulum and reed switch-based method 2 or accelerometer-based method 3,4,6 to sense wheel pendulum and reed switch-based device on a double drum that simulates wheelchair use. The percentage errors for the device when estimating the speeds varying from 0.8 to 1.8 m/s were found to be 1 and 5%, respectively.…”

“…Coulter et al 4 investigated a wheelmounted tri-axial accelerometer and found the device was highly accurate in estimating wheel revolutions, absolute angle and duration of movement (ICC (2,1) > 0.999, 0.999, 0.981, respectively) when 14 wheelchair users were asked to propel their wheelchairs forward and backward along a course. Sonenblum et al 3 evaluated a wheel-mounted tri-axial accelerometer in detecting wheelchair movements and estimating distances traveled. They found that the device had accuracy greater than 90% for various wheelchair and wheel types, propulsion techniques, speeds, and wheelchair-related activities of daily living including propulsion, food preparation, handwashing, loading a dishwasher, entering a bathroom stall, and using an elevator.…”

Objective: To develop and evaluate a wireless gyroscope-based wheel rotation monitor (G-WRM) that can estimate speeds and distances traveled by wheelchair users during regular wheelchair propulsion as well as wheelchair sports such as handcycling, and provide users with real-time feedback through a smartphone application. Methods: The speeds and the distances estimated by the G-WRM were compared with the criterion measures by calculating absolute difference, mean difference, and percentage errors during a series of laboratory-based tests. Intraclass correlations (ICC) and the Bland-Altman plots were also used to assess the agreements between the G-WRM and the criterion measures. In addition, battery life and wireless data transmission tests under a number of usage conditions were performed. Results: The percentage errors for the angular velocities, speeds, and distances obtained from three prototype G-WRMs were less than 3% for all the test trials. The high ICC values (ICC (3,1) > 0.94) and the Bland-Altman plots indicate excellent agreement between the estimated speeds and distances by the G-WRMs and the criterion measures. The battery life tests showed that the device could last for 35 hours in wireless mode and 139 hours in secure digital card mode. The wireless data transmission tests indicated less than 0.3% of data loss. Conclusion:The results indicate that the G-WRM is an appropriate tool for tracking a spectrum of wheelchairrelated activities from regular wheelchair propulsion to wheelchair sports such as handcycling. The real-time feedback provided by the G-WRM can help wheelchair users self-monitor their everyday activities.
