The history of the wheel chair can be traced back to the ancient Egyptians who used hand-pushed carts for people who were unable to walk. Over the years, the wheel chairs evolved to the ones we see today. The earliest wheel chairs were bulky 50-pound seats that featured vinyl upholstery. Today, the wheel chairs are much lighter, more maneuverable and far more comfortable.
Most people use the chair armrests for getting out of the ergonomic chair. The danger here is that the chair will move backwards and you will end up on the floor, without locking castors. If you are in the category of Big or Tall, then you are going to be in even more trouble trying to get up from the floor.
You need to lunge when applying many of the techniques. If your trunk is aligned in a lunge position, you will notice that you are glancing at the floor. This is an unnatural position. We elicit an orienting reflex that makes us align our gaze to the horizon. So your habitual tendency will be to lift up your head and extend your back into a very vertical position to see straight ahead. This pulls your spine out of an aligned position and causes hyperlordosis in the lower back. This makes it a great deal more difficult to stabilize the lower back and creates undue stress to the joints of the spine.
