A comparison of two methods of eliciting the ankle jerk.


Two methods of eliciting the ankle jerk have been compared. One, the traditional method, involved tapping the Achilles tendon (the tendon tap); the other (the plantar tap) involved tapping the sole of the foot. The study was done on 110 inpatients in the medical wards of a teaching hospital. The results showed an 89% agreement between the two methods. The extent of agreement was unrelated to the level of experience of the examiner. Forty three per cent of patients favoured the plantar tap method; 14% the tendon tap. The plantar tap method of eliciting the ankle jerk is an acceptable alternative to the traditional method.
