In this video, I explain and demonstrate the specific torsion test, a special test used in the assessment of lumbar rotational instability. Farfan and co-workers (1970; see also Farfan, 1973) have studied in detail the torsional strength of the motion segment. Only about 35 per cent of its torque resistance was . Some of the tests described include Spurling's test and Jackson's test for the cervical spine, load and shift test and apprehension test for the shoulder, and supraspinatus test and drop arm test to assess the rotator cuff.
After axially rotating both whole motion segments and isolated discs to failure, Farfan found that torsional damage manifested as separation of the disc’s peripheral lamellae .

Farfan (1973) has found that the disc is particularly at risk when subjected to bending and rotation and has put forward the hypothesis that torsion is the main reason for disc failure. This agrees with earlier observations by Farfan and Sullivan (1967) of the orientation of the facet joints in relation to disc failure, and is presently subject .astral torrents. farfan torsion test. crank torsion toyota.torsion trailer axles.. fifth gear test track.farfan torsion test. drop test methods.. farfan torsion test..

Introduction. The potential for torsion to damage intervertebral discs was first examined by Farfan [1, 2].After axially rotating both whole motion segments and isolated discs to failure, Farfan found that torsional damage manifested as separation of the disc’s peripheral lamellae and foraminal occlusion, similar to the annular changes observed during the early . Abstract. Background and PurposeAlthough many studies have described clinical examination measures for the diagnosis of lumbar spinal instability, few of them have investigated the sensitivity and specificity of the measures that were used.The authors devised a passive lumbar extension (PLE) test for assessing lumbar spinal instability. The purpose of .FIGURE 11.25 Farfan torsion test. The examiner stabilizes the patient’s ribs and spine at approximately T12 with one hand. The other hand lifts the anterior aspect of the ilium backward, causing the spine to rotate to the opposite side. The test is positive if symptoms are reproduced. - "Anatomy of the lumbar spine." QUADAS scores ranged from 16 to 25 out of a possible 26. The passive lumbar extension test was the most accurate clinical test, with high sensitivity (84%), specificity (90%), and a positive likelihood ratio of 8.8 (95% CI: 4.5, 17.3), indicating that this clinical test may be useful in the differential diagnosis of structural LSI.
Stress-Relaxation Torsion Test: This test measures how torsional stress decreases over time at a constant strain, relevant in applications where long-term stress relaxation is a concern. Creep Torsion Test: In this method, a constant torsional load is applied for an extended period to observe how the material deforms over time, known as creep.Study with Quizlet and memorize flashcards containing terms like Babinski Reflex, Brudzinski-Kernig Test, Femoral Nerve Traction Test and more.

Farfan HF (1969) Effects of torsion on the intervertebral joints. . The aim of this study was to test the hypothesis that disruption visible with HR-MRI post-testing corresponds with . Purpose of this three-test: This test is used to check the presence of SLAP lesions = biceps tension test . This test is used to check the labrum tear of the shoulder = clunk test; This test is used to check the torn of the labrum of shoulder = compression rotation test; Biceps tension test Technique of performance: Other major motivations to study disc mechanics are to develop and test surgical implants such as prosthetic intervertebral . 1986) and 25–50% of the transverse cross-sectional area (Farfan et al., 1970, Nachemson, 1960 . 1986), and immersion in fluid reduces an IVD's stiffness in torsion, axial compression, and lateral bending by .
Early torsion stiffness (ETS) was calculated between 20.0 and 40.0 % of the TMF, while late torsion stiffness (LTS) was calculated between 60.0 and 80.0 % of the TMF. TS was estimated by means of a least squares fit of a straight line through the torsion load–displacement data with the slope of the fitted line representing stiffness.
