AbstractThe tissue underlying skin mounted accelerometers introduces errors to the data they collect . As a consequence various data correction attempts have been made to minimise the effect of local tissue-accelerometer vibration [1,2]. However, accelerometers are not always mounted directly onto the skin. It is often impractical to do so for studies that measure activities during day-to-day living where strap mounting may be a more common attachment method. Therefore an understanding of the response of strap mounted accelerometers is also necessary. As the straps surround irregular shaped body segments strap mounted accelerometers may suffer from poor coupling when compared to skin mounted accelerometers, as well as additional vibration of the strap and pre-loading effects of tissue due to strap tension. This can be especially prevalent for straps around the waist, mounting accelerometers to measure motion at the spine. The aim of this study was to investigate whether the damped frequency (fd) and the logarithmic decrement (δ) of the local system (accelerometer, strap and local tissue) can be estimated so that the Smeathers’ method of data correction  can be applied to strap mounted accelerometers at the lumbar spine.
