Slump Test: Sensory Responses in Asymptomatic Subjects

Om slump test for å finne ut av nevropatisk smerte eller betennelse.

«While non-neural structures such as subcutaneous connective tissues, skin, blood vessels, and fascia may also be placed under increasing loads during neural tissue testing, Coppieters et al demonstrated that successive stages of the Slump Test did not alter the perception of experimentally induced muscle pain (i.e., non-neural pain). This finding provides some validation for use of the Slump Test in the examination of neural structures.»

«The procedure was divided into four stages:

  • SS—the subject was asked to put her hands behind her back, to slump at the mid- and lower back, and to tuck her chin into the chest, while the examiner placed his hand at the cervicothoracic junction to monitor cervical position (Figure 1.2);
  • KE—while maintaining the above position, the subject was asked to extend the left knee until full extension was reached (Figure 1.3);
  • AD—the subject was then asked to dorsiflex the left ankle (Figure 1.4);
  • CE—the subject was asked to maintain the lower limb position while the examiner removed his hand from the cervicothoracic junction and the subject extended the neck (Figure 1.5).
  • The subject was then asked to assume a comfortable sitting position and any residual responses were recorded (Figure 1.6). The examiner practised the test procedure several times on one subject to increase the consistency in test application prior to data collection.»

«All responses were located in the back or neck for the 29.8% of subjects who experienced a sensory response during SS, but for the subsequent three stages of the test, the vast majority of responses were located in the thigh, knee, or calf (Table 1)»

«A positive Slump Test implicates neural tissue as the source of symptoms. As found in this study, responses other than the presenting symptoms may simply be an artefact of the test, typical of the normal response in asymptomatic subjects; such responses must not be assumed to indicate a positive Slump Test. Bilateral comparison is advocated in interpreting this test.»
