| Slope | Action | Construction |
---|---|---|---|
1 | Low lumbar | shift of the trunk at the base | The whole trunk is shifted toward the concavity of the lumbar curve |
2 | High lumbar | elevation of the emithorax | The last ribs on the side of the convexity are elevated with a gradually decreasing compression in a down-up direction |
3 | Lumbar | shift of the trunk at the base and elevation of the emithorax | Combination of 1 and 2, on the same side |
4 | Thoracic | push on the distal ribs below the apical vertebra | On the side of convexity of the curve. All the ribs involved in the slope must be pushed. The rib corresponding to the apical vertebra is not involved (and sometimes also that below the apical) |
5 | Distal thoracic | push on the distal ribs above the apical vertebra | On the side of concavity of the curve |
6 | Proximal thoracic | push on the distal ribs above the apical vertebra | On the side of concavity of the curve |
7 | Thoracolumbar | elevation of the emithorax and push on the distal ribs below the apical vertebra | Combination of 2 and 4, on the same side |
