Hand :
Put the arm in hot water and bend it to follow the curve of your hand. 5 to 10 sec in boiling water is often enough. Important : thermoforming operations can be done without any effort. If you can’t bend the arm that mean you have to put it longer in hot water.
Thumb :
Remove the thumb part and it elastic string. Cut the elastic string if the knot is too tight.
Put the thumb part to the opposit size of the wrist and insert elastic string to match with your thumb. Make a knot with the elastic string.
Tips :
You can carefully put the hand dynamic splint in hot water if the thumb part is too tight.
Burn the end of the elastic string before inserting it in the press button.
- Left the hand dynamic splint at room temperature (less than 40°C) in a dry place.
Finger dynamic splint
Finger dynamic splint works with two flat springs on each sides of the finger. Springs come back to extension position by themselves. We propose different sizes and flexion force to apply on springs.
