Dynamic balance and compensation
Your learning goalAnalyze movement patterns instead of repeating a standardized treatment pattern.
Elevates the eyebrows.
Contribute to medial brow and glabellar expression.
Closes the eyelids; contributes to expression around the eye.
Observe the system
Advanced assessment considers how adjacent muscle actions influence the observed expression. Record rest, voluntary animation and the transition between them. A patient may recruit the forehead to assist brow elevation; an asymmetric smile may predate any treatment. Compare consistent views rather than relying on a single still photograph.
Separate causes
A line, asymmetry or heaviness can reflect anatomy, learned movement, prior treatment, compensation or a neurologic issue. Describe the finding, its timing and functional effect before attributing it to a specific muscle. New or unexplained weakness may need medical assessment rather than cosmetic adjustment.
Defend the endpoint
Explain which movement the plan is intended to change, what should remain functional and how success will be assessed. The safest endpoint may preserve movement or accept baseline asymmetry. Discuss a staged plan and uncertainty with the patient and instructor.
- Look at transitions as well as still images.
- Distinguish compensation from the primary concern.
- Define a functional endpoint.
Put the reasoning to work.
A patient asks for complete forehead immobility but uses forehead activity to hold the brows up.
How does this change your reasoning?Pause and write your response in the workbook, then compare your reasoning.
Read the case discussion
Discuss compensation and the risk of an unwanted brow change. Present alternatives and a conservative individualized plan for instructor review.
