Need advice
I work on pro athletes intermittently. For the groin work, it has mainly been on basketball players and tri-athletes.
Personally I don't have the client hold thier jewels, but I think it can be a good idea.
I frogleg supine, do a simple drape, tuck as high as I can, and start working my way up the adductors. As I get closer to where I need to be (attachments), I let them know where I am going, and what I am looking for... tightness, adhesions, etc.... and make sure to ask if it feels like I am working the problem area they are really having an issue with.
When I get to a spastic area in the region of the attachments, I will peg it with my fingers and wait for it to release or at least loosen. This has been my most effective method to date. I have been known to get right at the attachments on the pubic bone in the past when it was necessary, but much of the time, I can peg right below the edge of the bone. Much of my work is by feel - specific to the tightness/restrictions, and not due to a pre-conceived notion regaring specific muscle or tendion I think the problem is coming from.
Depending on the situation with the musculature, I may drop all the way back down to the medial knee and start working my way up again. I may even do this proceedure again and again and again. Or, I may stay high. Usually though, I am moving around a lot. When I work that way (re-doing the proceedure), most times I will find that on the second, third or fourth run, I can work quickly around the medial knee and lower 1/3 of the medial thigh, and will find the restrictions become lessened as I am am working my way up. So, I may end up spending only 10 seconds around the lower 1/3 of the thigh, but still spending a few mins. (between 2 and 7 mins.) at the medial 1/3 of the thigh and a few more mins. (probably about 3-6 mins. - sometimes more, depending on the situation and problem) at the upper 1/3 of the thigh and attachements. In this particular method, I will find that at some point I can peg the attachment and it will eventually release, though it may take 15 mins. to get it to do that, or it may take as much as a half hour + (plus).
A side note, is that I may work all the way up from the foot, with a good portion of my work on the lateral tibia. Deep, with rocking motion of the foot while stretching out that area. It is not necessarily comfortable, and when I do it, I can actually lay the medial portion of the foot on the table if the leg will allow me to stretch it that far, all the while stripping the area along the lateral tibia, within about a two inch span while working the entire length of the tibia. Hope that makes sense.
Sometimes I will also stop in the middle of my adductor session and just give the area a break. If I do that, I'll usually move over to the other leg for a while (not doing the adductor attachments on the other leg unless there is a need).
I definitely work the SI joints at the end of a session like this, with something that is similar to a sheering compression type of work - client prone, forearm to the lateral edge of the sacrum, with deeper pressure, while the drape is in place. In this technique, my drape will not slide around under my forearm.
I hope that helps you formulate a plan. Know the anatomy... is my best advice.
