The tennis may have triggered the pain. But the story probably started earlier.
A recent JANMI case involved an active woman in her 50s who developed annoying lower-back and SI-area pain after a normal tennis session.
Six months earlier she had undergone hip replacement surgery.
As she gradually increased her walking over the following months, something interesting was happening on the opposite side — increasing calf and Achilles stiffness, together with restricted ankle movement.
From a biotensegrity perspective, this becomes interesting.
The body doesn't operate as a collection of separate muscles and joints. When movement or load changes in one area, the rest of the system has to adapt.
My clinical interpretation was:
restricted ankle → altered leg loading → pelvic adaptation → increasing lumbar/SI compensation → tennis becomes the trigger.
This doesn't mean the calf caused the back pain. It means we had good reason to look beyond the painful area and consider how load was being distributed through the whole chain.
That is central to the JANMI approach:
Where pain appears and where the story begins are not always the same place.
This is an individual case and clinical interpretation, not a diagnosis. If you have new or persistent pain, seek appropriate professional assessment.
