Here’s the things that I’ve been keeping in mind while performing LSJL loading. First, is that bone adapation itself can not make you taller. Bone adapts to the stimulus provided to it but not always in the way you want. If you stretch the bone it won’t get longer but rather stronger and more resistant to stretching(unless you stretch it with enough force as to get into the plastic deformation range).
Since the loads to cause plastic deformation would be extreme and difficult to apply properly the goal is to affect other types of stimulus within the bone to encourage longitudinal bone growth like the stem cells, attached ligament enthesis’, the periosteum, and other surrounding soft tissue.
The previous method of LSJL involved clamping the synovial joint region whereas enthesis LSJL involves clamping two bones against each other. The enthesis attaches into the bone so it would be a potential region where a new growth plate could form. The enthesis structurally resembles the zone of ranvier where stem cells reside to provide for the growth plate.
I noticed that I was getting better results with my arms than my legs as my wingspan had increased from 72.5″ to 74.5″. The arm method I use with the enthesis method is the same as the standard LSJL method but the leg method is different. The structure of all the joints is different so the loads are applied differently. In the LSJL studies, the scientists found that the amount of bone deformation induced by LSJL was actually very small and they theorized that the results(including partially longitudinal bone growth) due to lateral knee loading could be due to the creation of a pressure gradient. As fluid flows more easily from a lateral direction than an axial one. However, it’s also possible that the LSJL results were due to the loading of bone against each other(which are attached by ligaments). The screw that was used to load the rats knee and ankle was huge relative to the size of the knee and ankle so the screw would’ve easily been loading the bones against each other. This is in contrast to our method where the clamps are small relative to the knee and ankle.
With this new enthesis LSJL method I have not been getting definitive results on my arms and legs. However, it was a significant amount of time before I noticed that my arms grew longer by about 1 inch each. With the old method I loaded my arms by about a count of 500(with instances of stopping) with a clamp every other day. Now I do it for about 30-40 counts several times a day.
It’s possible that the sustained session was more effective than the intermittent sessions. I don’t think mechanosensitivity is a big issue. Mechanosensitivity is the decreased response of a tissue to load. We know that increased longitudinal bone growth is not going to come from bone directly. All cells have mechanosensitivity but not to the degree that osteocytes seem to have in bone. Osteocytes are more mature cells than stem cells and chondrocytic like cells so they would likely be less prone to adaptation.
So, I don’t think that cycling off of loading would be an issue for enthesis loading. And you probably need a minimum amount of time for it to be effective.
So I’m going to try to sustain the load on the sites for longer. I know for sure that I gained about an inch of arm length it’s just a matter of reproducing it.
