Reach distance consists of the three factors involved in reaching forward from the saddle: the distance from the back of the saddle to the transverse bar of the handlebars; full arm length (acromion to metacarpal heads) and upper body length (from flat surface of plinth to incisura jugularis
of the manubrium sterni in supported sitting).
Reflective markers were placed on 10 bony landmarks of the arm and trunk: processus spinosus of the seventh cervical and eighth thoracic vertebra, incisura jugularis
, processus xiphoideus, acromioclavicular joint, medial and lateral epicondyle, radial and ulnar styloid, and distal head third metacarpal (Figure 2(b)).
The markers were attached to the xiphoid process, incisura jugularis
(suprasternal notch), C7, T8, and, on the dominant side, angulus acromialis, deltoi'dus tuberosity, medial and lateral epicondyles of the elbow, radial and ulnar styloid processes (Wu et al., 2005).
