| THE
REBOUND EFFECT: |
| “High-force,
short-duration stretching favors recoverable, elastic
tissue deformation, whereas low-force, long-duration
stretching enhances permanent plastic deformation…In
the clinical setting, high force application has a
greater risk of causing pain and possibly rupture
of tissue.*”
Dynasplint® Systems improve range of motion by
creating permanent, non-traumatic tissue elongation
and remodeling, thus virtually eliminating the range
of motion rebound effect often observed in the clinical
setting.* |

“The
basic aim of splinting is to apply tensile stress to tissues
that are restricting motion…
We consider the TERT to be the key factor to be modified when
using splints to increase range of motion.”
