Document Summary
Key learnings: 4 commonly used physical function assessments, methods for assessment and clinical relevance, experience administering the sppb. If older adults are unable to do the recommended amounts of physical activity due to health conditions, they should be as physically active as they are able. Such forces may be static, like the continuous force of gravity or, as is the case with many mobile devices, dynamic to sense movement or vibrations. Acceleration is the measurement of the change in velocity, or speed divided by time: accelerometers measure acceleration (and most models also measure steps) Piezoelectric accelerometers: accelerometers do not just measure physical activity. These voltages indicate movement and acceleration along axes. Accelerometer axes: uniaxial accelerometer measures acceleration on 1 axis: vertical (z, triaxial accelerometer measures acceleration on 3 axes, vertical (z, forward (y, horizontal (x) Placement on the body: retail accelerometers, such as fitbits and apple watches, are typically worn on the wrist.
