Final answer:
A Grade 1 (Trace) in the assessment of Scapular Adduction (Retraction) typically indicates minimal or barely perceptible movement of the scapula.
Step-by-step explanation:
A Grade 1 (Trace) in the assessment of Scapular Adduction (Retraction) typically indicates minimal or barely perceptible movement of the scapula. In other words, there is only a slight retraction or posterior motion of the scapula during this assessment. This means that the scapula moves slightly towards the midline of the body, but not to a significant extent.
For example, if a person is asked to retract their scapula, a Grade 1 (Trace) would indicate that there is only a faint movement of the scapula towards the midline of the body. It may be difficult to visually observe this movement without close inspection or palpation.
