A recent study has shown that a single device on the trunk comprising an accelerometer and a gyroscope is capable of accurately detecting posture change and walking in older adults [31]. Limiting the sensors to a single body site results in an even neater monitoring system.
These ambulatory measures have many potential uses including objective assessment of mobility in a clinical or home-environment over a prolonged period (‘24 hour ambulatory mobility monitor’). This can be used as an initial assessment tool or as an adjunct to monitoring progress during and after rehabilitation
