Most people are familiar with the ‘healing cycle’ noted after a major operation.  Most people resume ‘full activity’ beginning one month after such a procedure, because this is when the production of collagen molecules, used to heal the wounds, is almost completed.  With this ‘healing cycle’, 15% of collagen is made during the first two weeks, 85% during the second two week period following surgery, or injury.  Therefore, at one month following a treatment, I can tell what has been accomplished, and what is yet to be accomplished, by treatment. This is why the month interval is generally chosen.  Can treatments be given more frequently?  Yes.  If there is a seven day wait after a treatment, subsequent treatment produces a ‘full’ reaction and a second ‘healing cycle’ that is layered on top of the initial one.  If you wait less than seven days following a treatment, the responses ‘blend’ and there is less than a full response to the second treatment.  We often have athletes who are preparing for a season, or a competition, or we have people traveling from great distance at great cost, who will get treatments at 7 day intervals.  And there is no ill effect from delaying treatment more than a month.  Each treatment is a self-contained, independent event, which produces a certain amount of strengthening of structures.  One treatment does not ‘depend’ on a former treatment in any way, so there is no clinical problem that results from delaying subsequent treatment.  It just takes longer to complete the process.
