Excerpt
We have developed a dynamic hand splint, with a quantifiable force, to increase the range of motion of the metacarpophalangeal (MCP) joint. A number of conservative methods, such as passive stretching, splinting, and serial casting, have been used to reduce finger joint contractures. Therapists often ask questions such as
• What is the amount and duration of force that will produce the greatest increase in joint range of motion in the shortest period of time?
• Are there some joint conditions that will have a greater increase in range of motion with a low force applied over longer periods of time as opposed to some joint conditions that respond better to higher forces applied for shorter periods of time?
• What is the amount and duration of force, if exceeded, that will cause a loss in hand function?
