CONTEXT Joint-position sense (JPS) plays a critical role in the stability of shoulder joint. Restoration of JPS is essential to improve rehabilitation outcomes in individuals with shoulder injury. However, the number of affordable and reliable shoulder-JPS measurement methods for everyday clinical practice is limited. OBJECTIVE To estimate reliability and validity of 3 simple shoulder-JPS mea...

With regard to the nonlinearity, installation errors and other uncertainties existing in biaxial inclination sensors of borehole inclinometer, this article contrastively applies traditional curve fitting method and artificial neural network theory in the error correction work of inclinometer. Besides, this article also establishes the coordinate transformation model and gives details about the ...

dual spacization of publishing means emergence of digital publishing in online and offline virtual environments along with analogue publishing. analogue publishing is a kind of publishing that is produced in the form of physical printed writings as they appear in a single paper, single or many pages newspapers and magazines and books, writings on leaves and pieces of trees, natural skin and lea...

Dual spacization of publishing means emergence of digital publishing in online and offline virtual environments along with analogue publishing. Analogue publishing is a kind of publishing that is produced in the form of physical printed writings as they appear in a single paper, single or many pages newspapers and magazines and books, writings on leaves and pieces of trees, natural skin and lea...

This pilot study investigated the reliability of an inclinometer to assess lumbar spine angle in three different cycling positions, and explored the relationship between lumbar spine angle and riding position, anthropometry, bike measures and low back pain (LBP). Cyclists were recruited from two cycle clubs. Anthropometric variables and bike setup were measured before participants' bikes were s...

This paper describes ongoing work into a portable mobility aid, worn by the visually impaired. The system uses stereo vision and sonar sensors for obstacle avoidance and recognition of kerbs. Because the device is carried, the user is given freedom of movement over kerbs, stairs and rough ground, not traversable with a wheeled aid. Motion of the sensor due to the walking action is measured usin...
