Key takeaway
Movement models can suggest questions to test. They cannot diagnose the cause of pain or assign every joint one fixed job.
A model is a starting hypothesis
Movement models, including those associated with Janda, can help a clinician consider how different body areas work together. They are guides for asking questions. They do not prove that a tight muscle or an unstable joint caused your pain, and they do not apply as fixed rules to everyone.
Joints perform more than one role
The hip needs mobility and force control; the lumbar spine moves while also managing load; the shoulder blade must be both mobile and controlled. What matters is whether a finding relates to the patient’s symptoms and task.
Testing should change a decision
An examination may compare a meaningful task before and after changing support, range, speed, or a neighboring joint. Not every patient needs every movement screen. Findings deserve more weight when they are reproducible and lead to a useful intervention.
Function improves through specific practice
Treatment may address a relevant mobility limit, then build strength and coordination in the activity that matters. Progress should be judged by function and tolerance—not whether every movement matches an idealized template.
Your next step
Ask how a movement finding relates to the task you want to do and whether changing it makes that task easier.
