12 months + of doing RM and the results continue to get better. I think that Mitch is right. No point doing the course unless you are willing or able to put into practice at least with some of your clients in its full form. There is a learning curve involved which can be both challenging and exciting. I don't think I have seen anyone fully 'get' RM or learn to apply RM fully from the course. It comes from applying the material, reviewing the manual and asking a few questions etc. I would define RM as predominantly a skill based method.
RM does involve moves with movement etc, but they are applied with very different rationale than when applying Mulligans. Hence the the rules in applying them are somewhat different.
Obviously I am biased, but I recon this is the way many MS physio's will be treating the majority of their clients in the future.
