In cervical spine, under friction free circumstances a force of approximately 7 percent of the total body weight separates the vertebrae. A minimum force of 11.25 to 13.5KG (25 to 30 l) is necessary to lift the weight of head when sitting and to counteract the resistance of muscle tension. The greatest amount of separation occurs during the first few minutes of treatment at a given force. To avoid treatment soreness, the first treatment should not exceed 10 to 15 lb. Muscle relaxation can be achieved at levels less than those needed for mechanical separation (4.5 to 6.75KG, or 10 to 15 lb) in the cervical spine. Progression of dosage at succeeding treatment will depend upon the goals and patient reactions.......


HI All
Regarding Mr Sdkashif,At first thanks alot of sir for ur intersting & informative posts...
Now i'm wondering about the tractional wieght u wrote them ,since i think they are too large weigth ,i know basically we apply a traction force for head eqaul to it's third wiegth ,so total wight of head is =(20-25)Kg.

As usually we apply athird to half of that wieght which is(8-12)Kg.
as wieght of body'll stabilize her body .
*again secondly how i can give her a tracion and she had a post operative lumber disc prolapse since 6 months( so can i give it to her what about tension of trapeziuse muscles as a result of traction force!!)

Any notes appreciated really..

Regards
