Intrinsic tightness Discussion Intrinsic tightness Discussion Intrinsic tightness may follow any inflammatory or spastic problem affecting the hand. The intrinsic muscles are deep in the palm of the hand, and are involved with complex motions of the fingers. Treatment options depend on whether the problem is thought to involve reversible inflammation, fibrosis or fixed contracture.
Most early cases respond well to specific intrinsic stretching exercises.
Refractory cases may require surgical release or lengthening.
