How to Test Reflexes: 14 Steps
Testing reflexes is an important part of a neurological examination, as reflexes give insight into the health of the nervous system. Assessing your reflexes can help determine if there are underlying issues that need medical attention. Here are 14 steps on how to test your reflexes at home or with the help of a professional.
1. Understand why reflex tests are important: Reflex tests can help determine whether certain imperfections or delay in responses signify an underlying neurological issue.
2. Get familiar with different reflex categories: There are three different types of reflexes – superficial, deep tendon and pathological reflexes. Each type serves a different purpose and requires a different approach.
3. Assemble necessary tools and materials: To conduct these tests accurately, you will need a rubber hammer, cotton swab, or dull pin for certain tests.
4. Find a quiet space: Choose an environment free from distractions to ensure accurate results.
5. Perform superficial reflex tests:
a. Abdominal reflex test – Stroke the abdomen diagonally, downward and outward; observe if the abdominal muscles contract.
b. Cremasteric reflex test – Stroke the inner thigh; observe if the scrotum on the same side contracts.
c. Plantar reflex test – Stroke the outer sole of the foot from heel to toe; observe if the toes curl downward.
6. Initiate deep tendon reflex tests:
a. Biceps – With a bent elbow, strike the inner part of the elbow crease; observe if the lower forearm moves forward.
b. Triceps – With a bent elbow, strike above the elbow; observe if there’s extension at the elbow joint.
c. Brachioradialis – Strike just above wrist joint in line with thumb with forearm resting on lap or testing surface; observe if forearm rotates inward.
7. Deep tendon reflex tests for lower limbs:
a. Patellar reflex – With the leg bent at the knee, strike just below the kneecap; observe if the lower leg kicks forward.
b. Achilles reflex – While sitting or lying facedown with one foot propped, lightly strike Achilles tendon; observe if foot jerks downward.
8. Test pathological reflexes:
a. Babinski’s sign – Stroke outer sole of the foot and observe toe movement; upward movement of big toe can signify neurological damage.
b. Hoffman’s sign – Flick distal phalanx of patient’s index or middle finger down; observe if there is involuntary flexion of thumb or other fingers.
9. Make notes: Record your findings, including which tests were conducted and the responses observed.
10. Compare both sides: For an accurate assessment, compare the results from both sides of the body to identify any asymmetry.
11. Use a grading scale: Reflex grading scales are helpful for scoring deep tendon reflexes, ranging from 0 (no response) to 4+ (hyperresponsive).
12. Consider variations in normal responses: Reflexes can differ between people, so keep in mind that not every response necessarily indicates a problem
13. Consult a medical professional: If you have concerns about your reflexes, consult a healthcare professional to evaluate your findings and provide guidance.
14. Follow up as needed: If issues are identified, follow up with appropriate treatment and continue monitoring your reflexes according to your healthcare provider’s recommendations.
By following these steps, you can effectively test your reflexes and gain valuable insights into your neurological health. Remember that while these tests may be helpful in identifying potential issues, always consult with a healthcare professional for proper evaluation and guidance.
