Knee-chair

Discs require nourishment, and this is achieved in part by frequent changes of pressure - such as can occur when posture is adjusted. Further work has shown that the best angle between thigh and back is 120 degrees. To make work at a desk feasible while retaining this angle, the knee chair has been introduced. 

These comments refer to conventional adjustable chairs. However, a knee-chair offers certain advarrtages such as reduced spinal cortqrression, and can also be adjustable. The required adjustments are somewhat different from those for conventional chairs. For certain types of work, such as drafting and some types of assembly work, an adjustable stool or even a sit-stand support, may be a better choice.

In the small hours, I heard Aislabie s footfall on the stairs. He tried to open the door quietly, but it banged against a chair, and he cursed. Then he sat down heavily on the edge of the bed and took off his shoes. I turned my back and wrapped my arms round my knees. 

I sank down a little on the hard chair, adjusting my weight so that one knee was pressed against the desk and my other foot stretched out almost to the hearth. The robin went on singing, and a shaft of sunlight shone directly onto my hand. I breathed the scent of embers, dust, and beeswax and became aware of the ticking of a clock, deep and rhythmic, with a faint click between each movement of the pendulum.

Now the drug was coming on strong and I was suddenly very, very stoned. The machete vibrated with authority and seemed to pull me from my chair, across the room and out the door into the yard, where I was forcibly thrown to my knees on the ground. For the first, and so far the only, time in my life I heard a distinctly clear voice speaking to me from within my own head.

To reduce the amount of torque required by the motor, the device was designed to be used by patients in sitting or supine position. The lower limb is straightened by supporting the foot with a chair or stool.
