What is the proper sequence when comparing strength bilaterally during testing?

• A. Ignore the uninvolved side
• B. Compare involved to uninvolved side after establishing baseline
• C. Only test the involved side
• D. Use normative data only

Answer: (B)

When comparing strength bilaterally, you need a personal reference point. Start by assessing the uninvolved side to establish what this person’s baseline strength and available effort look like. Then test the involved side and directly compare its performance to that baseline. This sequence provides an internal standard that accounts for the individual’s normal strength, so you can detect a true deficit, while also minimizing the influence of pain, guarding, or fatigue on the injured side. Relying on normative data alone can be misleading because people vary greatly in baseline strength, age, sex, and conditioning, and it doesn’t reflect the current status of the specific patient. Skipping the baseline or comparing only to norms strips away that personalized reference and can misrepresent the degree of weakness.
