The response to the slump test in a group of female whiplash patients.

This study was undertaken to assess the difference between the response to the slump test in 40 asymptomatic and 20 symptomatic female subjects with cervical pain after whiplash injury. Areas and alterations of pain responses during the test, and ranges of movement of knee extension, were analysed. The results demonstrated that the addition of knee extension and left ankle dorsiflexion during the slump test produced a significant increase in the intensity of comparable cervical symptoms in the whiplash group. The whiplash group also showed a greater limitation in knee extension range of movement during the test than did the control group. These differences suggest that pathological changes of the neural system itself or adjacent tissues, affecting the mechanics of the neural system, may be a contributing factor to these patients' cervical symptoms.
