How To Use Wrist Extension Coil Springs?

  1. Make sure at least 1 leg of the coil is bent in a U-shape intended to be sandwiched between 2 layers.
    Note: Avoid sharp angles and notches that would cause break points.
  2. Place the coil so that active patient motion winds up the coil.
  3. Position the coil if possible aligned with the physiological axis.
  4. To fix the coil arm: heat it up first, then melt it into the plastic layers.
  5. Bend the free coil leg also in a U-shape.
  6. Adjust the coil strength by augmenting or diminishing the number of coils with spring coil pliers.
  7. To replace a coil, heat up the coil arm, detach from the sandwich fixation and replace.
