What should you know about manual therapy nags snags mwms?

NAGs are gentle oscillatory movements commonly discussed for spinal joints. SNAGs pair a sustained glide with an active spinal movement. MWMs, or mobilisation with movement, apply a therapist-guided glide while you move a nearby limb or joint. The names describe technique families; they do not identify a diagnosis or guarantee a particular result.

A physiotherapist might discuss these methods when a movement feels restricted in conditions such as [Cervical Spondylosis](/conditions/cervical-spondylosis/) or after [Whiplash](/conditions/whiplash/). The direction, position and force should be adapted to your examination findings and response.

Ask the clinician to show the movement before treatment begins and explain what change they are looking for. Report sharp pain, tingling, dizziness, nausea or symptoms that travel farther from the original area. If the technique is appropriate, the therapist may repeat the movement, reassess function and connect the result to an exercise or activity adjustment.

Do not copy a spinal technique from a video or ask another person to apply force. Home movements should be simple, controlled and specifically taught for you. Improvement in one test movement is useful, but daily function and symptom behaviour also guide the plan.

Seek urgent assessment for new limb weakness, loss of coordination, numbness around the groin, loss of bladder or bowel control, fainting or severe pain after trauma. Stop neck or back treatment and obtain medical advice if symptoms spread, balance changes or a severe headache appears.
