“…Both procedures were repeated five times and patients were instructed to conduct progressive neural mobilisation home exercises. Nerve excursion of 6-7 mm during hip and knee extension has been demonstrated in early cadaveric studies [17]. Exercises or treatment techniques using these movements may therefore decrease venous congestion and endoneurial pressure [18].…”

Outcomes differ between subgroups of patients with low back and leg pain following neural manual therapy: a prospective cohort study

The objective is to determine if pain and disability outcomes of patients treated with neural mobilisation differ for sub-classifications of low back and leg pain (LB&LP). Radiating leg pain is a poor prognostic factor for recovery in patients with LBP. To improve outcome, a new pathomechanism-based classification system was proposed: neuropathic sensitization (NS), denervation (D), peripheral nerve sensitization (PNS) and musculoskeletal (M). Seventy-seven patients with unilateral LB&LP were recruited. Following classification, all subjects were treated seven times with neural mobilisation techniques. A successful outcome was defined as achieving a minimal clinically important change in pain intensity (11-point numerical rating scale), physical function (Roland Morris disability questionnaire) and global perceived change (7-point Likert scale: from 1 = ''completely recovered'' to 7 = ''worse than ever''). The proportion of responders was significantly greater in PNS (55.6%) than the other three groups (NS 10%; D 14.3% and M10%). After adjusting for baseline differences, mean magnitude of improvement of the outcome measures were significantly greater in PNS compared to the other groups. Patients classified as PNS have a more favourable prognosis following neural mobilisation compared to the other groups.

“…19,26,27,31,44 Cervical flexion has been suggested to increase tension within the lumbar nerve roots, resulting in an unfolding of resting slack within the nerve root. 9,10,43 Cervical flexion has been shown in research involving cadavers to cause 3 to 4 mm of cranial movement of spinal nerve roots within the thoracic spine. 9 Cervical flexion has been widely advocated as an additional maneuver to the slump test to further tension the neural system, leading to neural sensitization and symptom reproduction.…”

Hall et al 31 reported that the addition of cervical flexion during a straight leg raise test did not show any significant change in hip flexion, to first onset of manually perceived resistance, in either healthy individuals or a group with lumbar radiculopathy.…”

We studied blood flow in the canine sciatic nerve using a laser Doppler flowmeter. Blood flow was measured in 20 hind limbs of ten adult dogs at varying angles of hip flexion, hip rotation and knee flexion. Blood flow decreased as flexion and internal rotation of the hip increased and also with only slight flexion of the knee. With 90°knee flexion, the mean blood flow did not change significantly when the hip was internally rotated from 0°to 30°. When the knee was straight, the blood flow changed significantly during the same procedure. To prevent sciatic nerve palsy, attention should be paid to the positioning of the hip and knee during total hip arthroplasty.Résumé Nous avons étudié le courant sanguin dans le nerf sciatique canin en utilisant un débimètre Doppler laser. Le débit du sang a été mesuré dans 20 membres postérieurs de 10 chiens adultes à angles variables de flexion et rotation de la hanche et de flexion du genou. Le débit a diminué à l'augmentation de flexion et rotation interne de la hanche et aussi lors de la flexion légère du genou. Avec le genou fléchit à 90°, le débit moyen a peu changé pendant la rotation interne de la hanche de 0°à 30°. Quand le genou était en extension le débit a nettement changé pendant la même manoeuvre. Pour prévenir la paralysie du nerf sciatique, il faut faire attention au positionnement de la hanche et du genou pendant l'arthroplastie totale de la hanche.
