Tendons connect muscles to bone. They are rope-like materials that are smooth, white and shiny. They do not stretch or contract like muscles, but simply transfer your muscle movement to the bone. Ligaments are strong fibers that connect one bone to another to form a joint. They bind your bones and limit their range of motion.
Muscles create movement by contracting and expanding.
Causes of CTDs Repetitive stress injuries are not caused by a single event such as a fall or being struck by an object, although the pain and suffering may be the same. They result from repeated exposure to ergonomic stress factors. The following are leading causes of CTDs. Compression on hard and sharp edges, for example, resting your arms on the edge of your desk while writing, using the keyboard, or using a mouse for extended periods. Sustained or awkward body postures like sitting hunched over in a chair or extending your hand forward to operate the mouse on your computer.
