Twenty-four hour ambulatory mobility monitoring provides reliable and objective information, which can be used as an initial assessment tool or an adjunct to evaluating progress during and after rehabilitation. This is ready for incorporation into clinical practice and is already in use in the Netherlands [27].
It is envisaged that the number and type of applications for this technology will increase as its potential is recognised. For instance, it is under investigation in patients with Parkinson’s disease as an objective assessment of mobility and tremor [33, 34] to detect changes with modifications in drug treatment. Accelerometers have also been implanted in hip prosthesis and have been shown to detect loosening [35].
The miniature nature of accelerometers has made their incorporation into clothing possible by integrating the sensors into fabric [36] which would facilitate compliance in long-term mobility monitoring.
As outlined in this paper, accelerometers are currently used primarily in a research setting, however, the processing algorithms and monitoring techniques have been extensively validated. The next phase in the development of accelerometer-based instrumentation is incorporation of this research expertise into a commercial device. Creating a product that is easy to use and acceptable to clinicians would be a major design goal. Other issues include making the device waterproof and developing sensors that are easy to apply and re-apply. The challenge facing clinicians and the medical devices industry is to harness this technology making it practical and acceptable for incorporation into everyday rehabilitation practice.
