Hey niggas, I’ve recently been hearing about LSJL and decided to do my own research, this is what I found
Lateral Loads to the epiphysis were first found to be a potential way to increase bone length at Purdue University by Ping Zhang, Hiroki Yokota, and Charles Turner(RIP)
The joint loading modality was found to increase bone length in mice up to 16 weeks old(Knee loading promotes longitudinal bone growth in both young and adult mice) and had dramatic changes to bone structure.
We tried to emulate the device described in patents such as (WO2005027735 - APPARATUS AND METHOD FOR ENHANCING BONE FORMATION) using clamps
The main principle of SJL is that lateral loads to the epiphysis are ultimately the best way to provide elastic deformation to the bone as the epiphysis is more easily deformable than the diaphysis. This deformation creates a fluid flow pressure gradient which stimulates the entire bone. Lateral loads are superior to axial loads because the bone is stronger axially than laterally. Since fluid flow is so important to bone lateral loading is the best way to "squeeze" the fluid around the bone. Lateral loading also creates tensile strain along the length of the bone creating potential elongation on the axial axis thus potentially lengthening the bone with plastic deformation.

- A study on mice showed knee loading increased tibia length by 2.3% in young mice and 1.5% in adult mice (16 weeks old, near skeletal maturity).
- Another source notes that female mice reach growth completion around four months, making the 1.5% gain in "adult" mice significant.
- A patent is referenced for a device that applies oscillating, lateral mechanical load to joints to generate fluid flow and enhance bone formation.

Here is what we found:
- Many people reported increases in bone width which I thought was amazing and width is just length on a different axis so if we could find out why it increases width than we could transfer the principles so it increases length.
Unfortunately, the people who reported increase in joint width considered an off target effect so they wouldn't try to prove it or reproduce it. - LSJL reduced temporary height. I believe this is due to the clamps driving fluid out of the articular cartilage which is restored over time.
- People reported knees cracking. This is again to I think temporary fluid loss from the cartilage.
- Some reported small height gain but it was never validated and unlike width gain it could have been wishful thinking

Directions for LSJL
- I believe that torsion, gravity, and vibration are the better way to go as they more dynamic. If you look at Hiroki Yokota's latest papers they learn more towards vibration in bone. We have anecdotal and study evidence that arms can grow post puberty but not legs and the reason I believe is that the arms likely experience these three load types more than legs.
- LSJL could help with limb lengthening surgery recovery as according to the paper Effects of surgical holes in mouse tibiae on bone formation induced by knee loading, lateral loads could help nonunions heal faster.
LSJL should be applied while joints are straight as possible.
You should try to "warm" up the knee after to restore any fluid loss from the cartilage We need to find a new device for LSJL as the clamps had too much slippage and ideally the device should be worn while moving
So what I recommend regarding LSJL
- There definitely needs to be more formal studies here
- if you are going to try then try it while the joint is as possible(so cartilage is at its strongest and less fluid gets driven out)
- It may be best to use clamps rather than your hands as clamps can provide more optimal and consistent force.
What can we learn from LSJL
The main principle of SJL is that lateral loads to the epiphysis are ultimately the best way to provide elastic deformation to the bone as the epiphysis is more easily deformable than the diaphysis. This deformation creates a fluid flow pressure gradient which stimulates the entire bone. Lateral loads are superior to axial loads because the bone is stronger axially than laterally. Since fluid flow is so important to bone lateral loading is the best way to "squeeze" the fluid around the bone. Lateral loading also creates tensile strain along the length of the bone creating potential elongation on the axial axis thus potentially lengthening the bone with plastic deformation.
