The Backstretcher definitely has a positive effect on RSI complaints in the neck and shoulders. He manipulates the thoracic region and puts your spine back into the correct position, relieving the pressure on the neck, shoulder and lower back.
The Backstretcher or Rolastretcher can certainly help with a hernia. By stretching the (especially the thoracic) spine, the spine becomes more mobile and there is more space between the vertebrae. The shape improves the posture. This reduces the load on the lower back and neck, which also has a favorable effect on a hernia.
You can try all stretchers on a 14-day trial. You must first pay for the Stretchers in advance. In case of doubt, a different trial period can be agreed upon in consultation. If the stretcher has no effect, you can return it. You do pay the shipping costs back and forth. (Shipping costs in total approx. € 12,-)
