FRC PAILs and RAILs Methodology

Question 1

What does PAILs stand for in the FRC methodology?

Accepted Answer

Progressive Angular Isometric Loading

Answer

PAILs stands for Progressive Angular Isometric Loading, referring to contractions directed into the stretch that progressively ramp up in intensity to expand end-range capacity.

Question 2

In the PAILs/RAILs protocol, which contraction direction defines PAILs?

Accepted Answer

Contracting into the stretch to push deeper into the range

Answer

PAILs involves isometric contractions directed INTO the stretch, activating the elongated muscles at end-range to signal tissue adaptation.

Question 3

What does RAILs stand for in the FRC system?

Accepted Answer

Regressive Angular Isometric Loading

Answer

RAILs stands for Regressive Angular Isometric Loading, involving isometric contractions that pull away from the end-range position to train active range ownership.

Question 4

What is the recommended minimum passive stretch duration before initiating PAILs contractions?

Accepted Answer

2 minutes

Answer

FRC protocol recommends a minimum of 2 minutes of passive stretching before PAILs to allow neurological adaptation and diminishment of the stretch reflex.

Question 5

During a PAILs contraction, the practitioner typically begins at what intensity and progresses toward what maximum?

Accepted Answer

20% MVC progressing to 100% MVC

Answer

PAILs begins at approximately 20% maximum voluntary contraction and progressively ramps to 100%, which is the 'Progressive' element of the technique.
