Expected findings - Palpable and/or observe a visible contraction of the medial hamstrings, slight knee flexion, and equivalent hamstring reflex reactivity when compared to the contralateral extremity

Equipment - Non-latex Taylor (i.e., tomahawk style hammer) or neurological reflex hammer

Testing procedures

1. The distal thigh and knee must be readily palpated and free of restrictive clothing (i.e., a tightly rolled up pant leg).
2. Position the patient in supine.
3. Stand to the side of the patient at the level of his or her knee.
4. Place the knee that is being examined in 45-60 degrees of flexion.
5. Localize the medial hamstring tendon (i.e., semimembranosus and semitendinosus).
6. The muscle is typically relaxed, but reinforcement procedures can be used if needed.
7. Place your second and third finger over the tendon approximately 3cm above the level of the posterior joint line.
8. Swing the reflex hammer loosely between your thumb and forefinger through a 45 to 60 degree arc, while making certain the hammer is aligned perpendicular to the tendon.
9. Standardize your finger placement, size of reflex hammer, and force if needed.
10. Palpate and visually observe the response to the provided stimulis (i.e., contraction of the hamstrings and flexion of the knee).
11. Repeat the procedure.
12. Document your findings.
