Passive physiological intervertebral movements

Passive physiological intervertebral movements are like a very gentle back massage for your spine. Your spine is made up of little bones called vertebrae, and in between each one, there is a soft cushion called the intervertebral disc. When you move your back in different ways, these discs can move too, and that's called physiological movement.

Passive physiological intervertebral movements happen when someone else moves your back for you. They might gently push or pull on your spine to encourage those little discs to move around. This can help your back feel more loose and relaxed, kind of like how you might feel after a nice stretch.

But why would someone want to have passive physiological intervertebral movements done? Well, sometimes our spines can get stiff or sore, especially if we've been sitting or standing in the same position for a long time. Having someone gently move your back can help to ease any discomfort and get those little vertebrae and discs moving again.

Overall, passive physiological intervertebral movements are a way to give your back a little TLC and help it feel better. It's important to always have a trained professional perform these types of movements to ensure safety and effectiveness.
