ZusammenfassungEine Nackenflexion beeinflusst nachweislich die Mechanosensibilität von neurodynamischen Testungen der unteren Extremität. In der Literatur wird diskutiert, ob sich dieses Phänomen durch eine erhöhte (intraneurale) Spannung des Nervengewebes und/oder einen protektiven Reflexmechanismus des motorischen Systems erklären lässt. Bislang konnte kein protektiver Mechanismus in Form einer modifizierten muskulären Rekrutierung als mechanosensibler Parameter zwischen der passiven Nackenflexion und der unteren Extremität gemessen werden.Alle in diese Querschnittsstudie eingeschlossenen 30 asymptomatischen, männlichen Probanden führten den neurodynamischen Straight-Leg-Raise-Test und Slump-Test durch. Um einen möglichen Einfluss der passiven Nackenflexion auf die muskuläre Rekrutierung der unteren Extremität festzustellen, wurden während dieser sensibilisierenden Bewegung die muskuläre Rekrutierung und das Bewegungsausmaß mittels Elektromyografie und Inertialsensorik (kinematische Messtechnik) gemessen.Die Studienergebnisse bestätigten einen segmentübergreifenden Einfluss der passiven Nackenflexion auf die muskuläre Rekrutierung der unteren Extremität. Deren Muster deuten möglicherweise auf einen protektiven muskulären Mechanismus in endgradigen neurodynamischen Positionen hin.

Straight Leg Raise

Background: Cervicogenic headaches (CGH) can be the result of dysfunction of the upper cervical spine. Due to the soft tissue connection between muscle, cervical fascia, and dura, this region might contribute to the development of CGH. Objective: Evaluate if subjects with CGH have neural tension signs. The secondary objective was to investigate if a correlation between the position and mobility of atlas and cervicogenic headaches exists. Methods: 60 Subjects were recruited. Self-reported outcome measures, passive neck flexion rotation test, upper limb tension test (ULTT), slump test, and straight leg raise test (SLR) were assessed. Results: There was a significant difference in atlanto-axial rotation to the right with p=0.025. There was no statistical significance in left rotation. There was no significant relationship between CGH, ULTT, slump and SLR with P>0.05. Atlas position was significantly related to CGH with P<0.001, and position of the atlas was significantly related to atlanto-axial motion with p<0.001. Discussion: There is a direct relationship between the position and mobility of atlas and CGH. Fascial connections between structures could result in dural tension and should be considered when managing patients with CGH. The use of the ULTT, Slump test, and SLR test does not appear to be beneficial in identifying those with CGH.

Background: Lumbar radiculopathy is a nerve root disorder whose correct diagnosis is essential. The objective of the present study was to analyze the reliability diagnostic validity of eight neurodynamic and/or orthopedic tension tests using magnetic resonance imaging as the Gold Standard. Methods: An epidemiological study of randomized consecutive cases which was observational, descriptive, transversal, double blinded and was conducted following the Standards for Reporting Diagnostic accuracy studies (STARD) declaration. The sample size was 864 participants. Internal and external validity (CI = 95%) and reliability, were calculated for all tests performed independently. The diagnostic validity of the combined and multiple tests in parallel was also calculated. Results: The analysis indicated that only two tests performed independently had external validity, but neither had reliability or precision. The Straight Leg Raise test and the Bragard test performed in a multiple parallel way showed high sensitivity (97.40%), high negative predictive value (PV− 96.64%) and external validity (Likelihood Ratio− 0.05). The combined test of the Slump test and the Dejerine’s triad had internal and external validity. Conclusions: The Straight Leg Raise test and the Bragard test performed in a multiple parallel way and the combined test of the Slump Test and the Dejerine’s triad have clinical validity to discard lumbar or lumbar-sacral radiculopathy.

BACKGROUND: The cranio-cervical flexion exercise and sub-occipital muscle inhibition technique have been used to improve a forward head posture among neck pain patients with straight leg raise (SLR) limitation. However, little is known about the cranio-vertebral angle (CVA) and cervical spine range of motion (CROM) after applying stretching methods to the hamstring muscle. OBJECTIVE: To compare the immediate effects of static stretching and proprioceptive neuromuscular facilitation stretching on SLR, CVA, and CROM in neck pain patients with hamstring tightness. METHODS: 64 subjects were randomly allocated to the static stretching (n1= 32) or proprioceptive neuromuscular facilitation (n2= 32) stretching group. The SLR test was performed to measure the hamstring muscle’s flexibility and tightness between the two groups, with CROM and CVA also being measured. The paired t-test was used to compare all the variables within each group before and after the intervention. The independent t-test was used to compare the two groups before and after the stretching exercise. RESULTS: There were no between-group effects for any outcome variables (P> 0.05). However, all SLR, CVA, and CROM outcome variables were significantly improved within-group (P< 0.05). CONCLUSIONS: There were no between-group effects for any outcome variable; however, SLR, CVA, and CROM significantly improved within-group after the one-session intervention in neck pain patients with hamstring tightness.

The compatibility of low sulfate cement with naphthalene (NS) and polycarboxylate (PCE) type superplasticizers was discussed. The flowability of slurry and the adsorption of superplasticizers (SP) were investigated by mini slump test and TOC. The results show that severe compatibility degeneration is caused by low sulfate content in cement slurry. The water demand of slurry, the standard dosage and adsorbed amount of SPs were dramatically raised. In the cement slurry with low sulfate content, polycarboxylate type superplasticizers presents better performance than naphthalene type. The PCE with lower charge density presents better robustness. It is recommended in the preparation of concrete to avoid the incompatibility problems caused by lack of sulfate in cement paste.
