What is the recommended approach to testing strength bilaterally?

• A. Test involved side first
• B. Test both sides simultaneously
• C. Only test involved side
• D. Test the uninvolved side first to establish baseline, then test involved side for comparison

Answer: (D)

Testing strength in both limbs is most meaningful when you compare the involved side to the person’s own baseline. Starting with the uninvolved side gives you a clear reference for what this patient can normally do, so you can quantify the deficit on the involved side by direct comparison. It also helps minimize the influence of pain, guarding, or fear on the test results for the involved side, which could otherwise mask or falsely inflate strength. Once you have that baseline, you test the involved side to see how it differs. Testing both sides at once isn’t practical and testing only the involved side loses the crucial comparison to the patient’s normal strength. So, you establish the uninvolved baseline first, then assess the involved side for an accurate, clinically useful assessment.
