Instrument Assisted Cross Fiber Massage Accelerates Knee Ligament Healing- JOSPT 7-09.
The researchers did Graston Technique on 51 rats who's MCL's were surgically injured. 3X a week for 1 minute; 31 received 9 treatments, 20 received 30.
At the end of the treatments, the rats were sacrificed, and the MCL's were placed under an electron microscope for study. Then, mechanically strain tested also.
At 4 weeks out, the treated ligs were 43% stronger, 40% stiffer, and able to absorb 57% more energy. At 12 weeks out, both treated & untreated ligs were similar, with the exception of the treated ligs being 15% stiffer.
The authors hypothesize that the Graston Technique has an underlying effect on collagen, influencing the fibroblastic cells.
How do my blog readers feel about this? It was fast, and a hell of a lot cheaper than other popular tendon therapies (platelet rich plasma, stem cells etc). Would ASTYM work just as well? Or, how about good 'ole deep transverse friction massage, which doesn't cost a dime to learn (it is well described in Warren Hammer's book).
