Manual treatment work can be fatiguing. When you are working near your maximum level of effort with muscles that are fatigued, injury is likely to occur. It helps to know your maximum level of effort, and then consciously work at a much lower percentage of that maximum. Everyone has a different maximum level of effort. You can identify your level by your perception of the effort you use in your work.
Think about grading your techniques according to the effort you use to perform them. Use a scale of 1 to 10, where 1 is practically no effort and 10 is the most effort you could possibly exert. To be safe, stop using any technique you rated 6 or more; limit techniques with a 3-to-5 rating to no more than once or twice per session; and any techniques you do repetitively should not have a rating of any more than 2.
