Mother Brown Lymph Therapy

Consult your doctor first before doing these .
Synopsis :
A cheap and easy way to move lymph along , especially in the legs .
Discussion :
1.Method :
Tie a belt or towel in a figure 8 between the calf of one leg and the thigh of the other leg .
The calf and thigh are inside the loops of the 8 .
Lie on your back with your knees bent .
Open and shut your legs vigorously and rapidly , adjusting the distance between the legs so the belt shifts upwards towards the torso .
1.1 A variant is with snap-kicks in the air . See Appendix B
1.2 Variant for the torso :
Loop belt around torso . Hold ends in hands . Lean against a wall and do slow , gentle squat .
Let belt wander .
Swap loops around after about ten minutes or when exhausted .
2.How does it work ?
When the belt stops the motion of thigh or calf , pressure of about two times systolic blood pressure is generated . (+- 2x 120 mm Hg)
This is enough to overcome lymph resistance ( which can be seen as about equal to diastolic pressure) .
See Appendix A for the theory .
3.Benefits :
3.1 Cheap
3.2 Can be done anywhere
3.3 Effective.
3.4 Exercise

Appendix A
Simple mechanics gives the relation
P = (1/pi) * (m/L) *(r/b) *w^2/d ... n/m^2 (Pascals)
Where p is pressure , m=mass of limb(kg) , L = length of limb(m) , w= angular speed of movement of limb(radians) , d= give in strap(m)
(r/b) ~ ratio of length of limb to width of strap as a first approximation .
Take (r/b) ~4 for a 10 cm wide belt .
Take d= 0.001 m as fairly unyielding strap
M , L can be obtained from http://www.dtic.mil/dtic/tr/fulltext/u2/710622.pdf
W can be obtained by counting number of open-shut movements over angle theta .
Typical value would be theta = 30 degrees , open and shut about twice a second .
This gives w=45/360 * 2*pi *2 = 1.5708 radians/sec .
M/L table :
Thigh 13.07 kg/m , p=785.40 * 13.07 = 10265.15*4 Pa = 308 mg Hg
Thigh 5.045 kg/m , p=785.40 * 5.045 = 3962.34 Pa = 120 mg Hg
This should move those dogies along !

This is without the Mother Brown technique above .
Adding the two gives synergism , and does not need to be so energetic .
