Neurodynamic techniques: sliders and tensioners in 3D
Neurodynamic techniques coordinate several joints to explore the relationship between peripheral nerves and surrounding tissues. Neurodinamic Atlas lets you compare sliding and tensioning using two anatomical 3D bodies.
Sliding and tensioning: what changes
A slider combines movements that increase loading at one end of the neural pathway while reducing it at the other. A tensioner coordinates movements that increase loading at both ends. These are coordination patterns: joint angle alone does not measure actual nerve tension or excursion.
Median nerve neurodynamic techniques
The upper-limb example shows elbow and wrist coordination. Compare both bodies at the same phase, show or hide the skin and adjust each variant's amplitude independently. The median nerve anatomy page and ULNT1 test guide provide context for the pathway being explored.
Sciatic nerve: sliders and tensioners in Slump
In the seated example, watch the knee and neck: the slider combines knee extension with the neck returning towards neutral; the tensioner combines knee extension with cervical flexion. Pause both bodies at the same instant to compare their positions.
Using the 3D comparison
Open the atlas and select Techniques. Choose Median nerve or Sciatic Slump, play the movement and change each body's range of motion (ROM). Labels show joint angles in degrees. On mobile, switch between Slider and Tensioner while keeping the animation phase.
Tests and techniques serve different purposes
Neurodynamic tests such as ULNT1, SLR and Slump represent examination sequences. The techniques comparison illustrates joint coordination. Atlas ranges are educational examples, not a treatment programme, a measurement of neural tension or an individual exercise recommendation.
