Range of motion

WBC translation

WBC separates range from usefulness: having a range, owning it, tolerating it, and needing it for real life are different questions.

Why it matters

• 1Helps evaluate mobility tools without treating bigger range as automatically better.
• 2Connects flexibility, mobility, joint capacity, and end-range control.
• 3Encourages retesting movement quality after a tool instead of chasing intensity.

Do not overclaim

• More range is not always the goal; some contexts require strength, control, or medical assessment.
• Short-term range changes after a tool do not prove permanent tissue lengthening.

Evidence note

Range of motion is a standard measurement concept; evidence for how specific tools change it is narrower and often short-term.
