Chronic Back Pain Relief Research And The MacBac

Chronic back pain relief research on the benefits of the MacBac Remedial, demonstrated that as abdominal muscular strength increased, crucial lower back and sciatic health benefits resulted.

What Is Pelvic Structural Muscular Force Dynamics?

In order to develop the MacBac I needed to conduct my own chronic back pain relief research. This led to the development of the concept of Pelvic Structural Muscular Force Dynamics.  Here's how the process developed.

The pelvic structure itself, behaves as a force absorbing framework of bones.

Six separately activated muscle groups, are able to and do, generate their own distinctive directional, retractile force to the hip bones. In short, your lower back is the force exchange foundation that allows your thigh and lumber muscles to work properly.

Whatever muscular forces you are using to walk, all goes into pulling your hips around. Not just the leg muscles either, because your lumber muscles are also pulling from your hips, which stops you folding over, like Mr floppy.

Your abdominals and Maximus Gluteus muscles will be engaged as you walk, which has the effect of stabilising mobile hip bones.

My chronic back pain relif research indicates that; in pelvic structural muscular force dynamics, it is the abdominal muscles that generate inward directional, retractile forces, between the hip bones.

Maximus Gluteus muscle groups generate outward directional pull forces to the hip bones.

The six directional forces that these muscle groups generate, probably mostly cancel each other out. However, a resulting vectorial force is more likely.

It was apparent with multiple Macbac Remedial exercise routines, that the resulting vectorial force was inward hip motion.

The ligament tissue bonding strength, is thought to be related to the strength of abdominal and other pelvic anchored muscles. The exercise routines increased abdominal muscular strength, chest strength and core strength.

Profound strength increases resulted from long term exercise patterns.

Speaking personally, forcing the abdominal muscles to pull the hip bones inwardly, is simply a function of multiple MacBac Remedial exercise routines, performed at force gradients ranging from 30 to 100 kilograms. Additional retractile forces by my lumber muscles to pull the hip/s upwardly, was a distinctive PSMFD that eliminated my chronic sciatic symptom.

Others that used the MacBac Remedial to eliminate chronic back pain symptoms, completed the process when thigh muscle groups pulled a hip into proper alignment.

These combinations of pelvic anchored muscles pulling hip bones about, reinforce the Pelvic Structural Muscular Force Dynamics concept.

The Relevance Of Pelvic Structural Muscular
Force Dynamics To 
The MacBac Remedial

The abdominal muscles that attach inside the pelvis are responsible for the inward directional stability of the pelvic structure.

That’s probably a meaningless statement at this stage, but it will make sense.

For now, just remember the concept that this muscle group is being tensed, which in turn applies inward retractile forces between the hip bones. Bones are made of solid material, compared to the softer ligament tissues that bond the hips to the sacrum plate. So, whatever retractile forces the abdominals produce, must go to stretching the bonding ligaments.

Again, you will need to hang onto the abdominals transferring all their retractile force to the pelvic ligaments, because ordinarily abdominals look to anything but, bone moving power house muscles. And you would be right to think that the abdominals do nothing, because until six pack abs came into being desired, they held no interest to anyone.

Then along came the MacBac Remedial to display awesome abdominal muscular strength gradients, that are capable of dragging hip bones inwardly.

That effectively causes the ligament tissues to stretch. Yes, small as these stretching actions are, the benefits are profound, because the bones being flexed, effectively transfer the energy required to flex them, to the ligament tissues.

Muscular forces applied between the hip bones, flex those bones, which in turn translates into ligament stretching actions. This ligament tissue action, rejuvenates the inward flexing resistance of those ligament tissues.

How the inward pelvic flexing force dynamic occurs

The lumber muscle group attach to the hips and apply a range of upward retractile forces to the structure, by exerting tremendous retractile forces between the hips and spinal column.

An example is when a pace bowler bowls the ball. His lumber muscles are applying all the force required at two places. The obvious being at his hand and the obscure being at his hip bones.

You may have seen our pace bowlers doing ‘stretching’ exercises, after a stint of bowling? A simple short MacBac workout would fix their ‘back’ pain, by allowing their abs to haul their mis-aligned hips into proper alignment.

 Labourers, road cyclist and athletes in general, regularly mis-align their pelvic structure. This event always produces back pain symptoms, which always cease when their structure returns to its proper alignment.

How the upward pelvic flexing force dynamics occur. 

Thigh muscular retractile forces apply downward pull forces to the pelvic structure. It is interesting here, because the legs alternately pull the hip bones downwardly when walking, or running. Can you imagine the twisting force gradients applied to your pelvis bonding ligaments? It would be close to alternating muscular retractile forces that are required to propel your body weight forward.

The alternating downward pull forces applied by the thighs, expose the duel downward directional force dynamics that translate into downward ligament rejuvenation.

Particular lumber and thigh exercises proved this force responsive characteristic of the pelvis, through control of and elimination of particular sciatic, lower back and back pains. Just s a sailor trims the sails for precise control, so to do the leg and lumber exercises trim hip alignment, in remedial pelvis dynamics.

How The MacBac Defined My Chronic Back Pain Relief Research

Initially, the Macbac remedial exerciser’s purpose was to provide an exercise platform for the abdominal muscles to directly lever against. The anticipated result was to build abdominal muscular strength, independent of spinal motion.

As a result of static contraction exercising, the existing back pain was reduced and even completely eliminated.  As well, the user experienced a sensation of firm support in the lower back region.

If you refer to our case studies you will see that continued daily exercising by three of the users displayed breakthrough results. The hip and sacrum bones were re-aligned as their abdominal muscles strengthened

Throughout 17 years of chronic back pain and relief research, this structural re-alignment effect was duplicated many times.

The importance of muscular strength

However, it was the muscular strength that users' abdominals exerted, against the Macbac Remedial exercise front plate, that governed re-alignment.

Younger men fixed their chronic back pain sooner, because they had the abdominal strength required. 

Case Study: Sean Barry
20 minutes of intense, multiple exercise routines to fix a 13 year chronic back condition. 

I have suffered with a constant pain in my back for the past 13 years from years of working in industrial construction. 

After about 20 minutes using the Macbac, I removed the device and immediately the pain was gone and has not returned since.

To be honest I was skeptical at first but as a previous sufferer of back pain, all I can say now is that anyone with this condition would be a fool to overlook the Macbac.

Case Study: Jarrod Coate 
Significant lower back pain for four years which, after several exercising cycles, was relieved after only a few days.


In both studies, it was the abdominal strength applied to the exercisers rigidly braced front plate block, that caused the hip and sacrum bones to re-align.

Studies done in 1999, first established that Macbac Remedial exercise routines produce structural re-alignment effects and that these effects eliminated back, sciatic, disc, and twisted gait conditions. Those physical re-alignments were displayed in the moulded back plates. Duplication of these studies is a simple matter.

Abdominal muscular retractile force, plus chest muscular retractile force, ranging between 40 to 70 KLG [assumed], applied to the Macbac Remedial front plate block, causes inward directional re-alignment of the hip bones. Abdominal muscular force gradients up to 50 KLG were noted, prior to my own pelvic re-alignment, in 1999.

The Role Of  The Lumber Muscles

Based upon the re-aligning functions of static contraction exercised abdominals, investigation of the static contraction forces involving the other muscle groups that attach to the structure, was conducted.

This resulted in the lumber muscle group being identified as exerting upward directional forces to the structure and both thigh muscle groups as exerting two downward directional forces, to the structure. Maximus Gluteus muscle groups are assumed to exert outward directional forces, to the structure.

Particular lumber and thigh exercises proved this force responsive characteristic of the pelvis, through control of and elimination of particular sciatic, lower back and back pains. Trimming the sails for more control is similar to the leg and lumber exercises, in remedial pelvis dynamics.

Static contraction exercise routines, involving the abdominals established the existence of inward directional flexing actions, by the hip bones. Core strength and abdominal strength increases resulted simultaneously. Inward hip flexing actions re-establish proper structural alignment, at a 70% success rate.

Particular thigh and/or lumber exercises complete the re-alignments, to raise the success rate to 90%. Multiple chronic conditions involving the back, neck, pelvic, leg and sciatic nerves, are directly caused by pelvic mal-alignments.

Further, two causes of back pain can now be distinguished, being pelvic trauma damages and work/activity pelvic mal-alignments. Both can be caused by externally applied force, with the work/activity being a short duration pain. Work/activity causes can be divided again, into excessive lumber/thigh muscular force being used and excessive sedentary activity. Activity and sedentary may appear to be an oxymoron, but not so in pelvic structural force terms.

Excessive sedentary activities force the pelvic structure to re shape, which consequentially results in particular lumber muscles being held in a stretch position. Distinctive static contraction exercising is the cure. Cyclists, taxi/truck drivers and office workers tend to sit their way into back pain. Static contraction type exercising that involves the abdominals, lumber and thigh muscle groups, easily switches off the back pain, because the hips respond to muscular generated forces.

Finally, preventative back health practices must involve the abdominal muscles, because core strength gradients determine lower back stability and spinal stability gradients. I expect aged people become stooped because their core strength fails.


  1. The pelvic structure is the force responsive foundation for the spinal column and thighs.

  2. This structure flexes in response to the muscular forces applied and its ligament tissues translate the energy of these forces, by directionally stretching. In short talk, this means your lower back health is directly related to the strength of all six muscle groups.

  3. Ligament strength is directional and related to the muscular forces that each muscle group applies, to the structure.

  4. Two treatable causes of back pain are apparent.
  • The first is work/activity caused and the easiest to eliminate.
  • The second is resultant to pelvic trauma damage and exists as chronic pelvic mal-alignment. 

Both causes have adversely applied force in common. Further, both causes are exacerbated by atrophied abdominal muscles and usually eliminated by MacBac Remedial exercise routines.
