Detection of daily postures and walking modalities using a single chest-mounted tri-axial accelerometer

Quantitative assessment of physical activities during daily life plays a significant role in evaluating the functional ability and the level of activity in healthy individuals and patients suffering from obesity, recurrent falling, Parkinson's disease, and back pain [1 –5]. In recent years, wearable inertial sensors with lightweight, long battery life, and large memory have become increasingly popular for ambulatory human motion analysis [6,7]. Najafi et al. [4,8] adopted the trunk inclination angle, obtained from the integration of the angular velocity and disc rete wavelet transform (DWT), to detect postural transitions (PT) from accelerometer and gyroscope signals of a chest-mounted sensor.
