thank you.

[@Gldtr39]

I watched all three pnf stretches. His left leg will be nice and loose lolol

[@torimalespini9923]

Thank you very helpful !!

Patient doing ACTIVE movt during Contraction of hip flexors or PT move the limb into more flexion passively

[@dascrazybro895]

both happen simultaneously i believe

[@user-ib3zp5sj6z]

Does patient must hold their breath during contraction?

[@joshuadhoundiyal8620]

I don't think that's optimal

[@pm-2039]

i think they just should normally breath instead of doing a press breathing or smt. else

[@dridihosni4140]

Agonist contract = the reciprocal inhibition, so we have to contract the quads in order to relax the hamstring before stretching , am I wrong ?!

[@SuperMisterKory]

I'm trying to wrap my head around it too. I believe you are correct. During the "relaxation" phase, the patient/client would be actively contracting the hip flexors (which includes the rectus femoris/quad group), in turn, relaxing the hamstrings, thus demonstrating reciprocal inhibition.

[@dridihosni4140]

@@SuperMisterKory yeah , honestly some of videos on CZcams make me confused.

[@SquatsAndThoughts]

@@dridihosni4140 In PNF stretching the roles are reversed. Antagonist refers to the tight muscle that you want to lengthen, agonist is the opposite muscle group. In this case, the antagonist is the hamstring, and the agonist would be the quadriceps. You are right.
As a side note, the rectus femoris is the only 2 joint muscle in the quadriceps, so the quad group isn't generally associated with hip flexion outside of rectus femoris.

[@mona8449]

i am confused is the HRAC is the same as CRAC or these are totally different techniques

[@mona8449]

please i need help in this if anyone can tell me and if crac is same as contract - relax but repeating the contraction idk

[@purpleheart5837]

CRAC is using contract relax technique in which there's isotonic contraction of the muscle in HRAC there's isometric contraction meanwhile the agonist contraction part is same.

​​@@purpleheart5837es youre right,, just follow the Name contact means ISOtonic while while hold means isometric
