Introduction
The Posture Pump® Penta Vec® Model 2500 is designed to provide relief for lower back pain and discomfort, including sciatica. This device gently lifts and expands the lumbar spine, facilitating decompression and hydration of the discs. It employs a unique blend of five simultaneous force vectors to help restore the natural curved shape of the lower back, which can become compressed over time, leading to stiffness and pain.
This manual provides essential instructions for the safe and effective use of your Posture Pump® Penta Vec® Model 2500. Please read all instructions and cautions carefully before beginning any use.

Setup and Adjustment
Before your first training session, carefully read and adjust the pelvic and foot-unit belts according to the following instructions to ensure proper fit and function.
Proper Set-up Recap
- Lie on a comfortable firm surface.
- The pelvic belt should be positioned below the waist and belly button, and should NOT be tight when fastened.
- Adjust the foot-unit belt so that your legs can be comfortably extended. The foot-unit should not be so far that legs cannot easily straighten or so short that it causes pain.
- With your heels pushed out and up on the foot piece, and your legs extended, the back/lumbar unit will slide below the buttocks, lifting the buttocks up and off the ground approximately 1 inch.

Note: Final adjustments to belts may be needed to change if heel thickness of shoes changes. Always wear shoes! Use Penta Vec® Model 2500 on a comfortable firm surface. For the more sensitive low back person, we recommend using Penta Vec® on your bed/mattress when first starting. Use Penta Vec® to hydrate the discs daily or as recommended by your health care professional. Even a 3-5 minute workout is beneficial.
Adjusting the Pelvic Pull
The pelvic belt is adjusted slightly loose around the pelvis, below the waist and belly button. This belt should not be tight when fastened.
- After pelvic belt adjustment, the buckle may be off center. Center buckle by pulling the buckle toward the center. Slide hip pads along belt to make room if necessary. If pelvic belt becomes twisted, also use this maneuver to untwist by pulling the belt all the way to the right and all the way to the left (several times) until belt becomes untwisted.
- Tuck excess pelvic belt into right hip pad if desired.

Note: If belt connections are protruding from the Back-Unit opening, simply pull right and left sides of pelvic belt away from each other before making adjustments.
Foot-Unit Belt Adjustment
The further apart Back and Foot-Unit are from each other, the less the pelvic pull; the closer they are together, the tighter the pull.
- a) To decrease pull: Open buckle flap completely and pull Foot Unit away from Back Unit. Lock buckle completely.
- b) To increase pull: Open buckle flap completely, grasp Foot-Unit and pull/slide buckle toward Back-Unit. Lock buckle completely.

Operating Instructions
Follow these steps for effective use of your Posture Pump® Penta Vec® Model 2500.
Training Instructions
- Grasp the two hand pumps, squeeze each pump separately to confirm which one operates the lowest air cell and inflate the lowest air cell first to a firm comfortable level, never to the point of pain. (Usually 1-9 complete pumps)
- Inflate the upper air cell to an equally comfortable level. (Usually 1-9 complete pumps)
- Squeeze both pumps at the same time. (Usually 1-5 more pumps)
- With your knees bent and feet firmly on the ground, rock pelvis up and back toward the belly button using your abdominal muscles to lift buttocks. Then rock downward using back muscles and allow lower back to gently stretch over air cells, lowering buttocks to floor. Gently rock back and forth 3-5 times or more.
- Then with both feet in the Foot-Unit and knees bent slightly, gently and gradually straighten legs pushing with your heels against the Foot-Unit. The Back-Unit will now slide down from your lower back toward your pelvis and buttocks (usually 1-4 inches). Hold this position for approximately 30 to 60 seconds, then relax your legs and slide forward so the Back-Unit is again under the small of your back and gently rock forward.
- Repeat step 5 several times with the Back-Unit inflated to a comfortable level or deflate air cells by pushing down on both air release buttons at the same time and repeat steps 1-5 as desired.
- On your last repetition, extend the Foot-Unit and hold for up to 8 minutes maximum. Gradually work up to this 8-minute goal over several training sessions, never extend legs for more than 1 minute in the initial training session!
- Relax your legs and slide forward so the Back-Unit is again under the small of your back. Gently rock forward, back and forward a few times.
- Deflate both air cells approximately halfway. Release Pelvic Belt from waist and remove belt from Foot-Unit. Move the Back-Unit toward mid and upper back - position it. Gently stretch arms over head to decompress the middle and upper back. Perform this movement several times as you slide and roll over the Back-Unit. Gently roll off exerciser and onto your left or right side slowly and carefully before rising.

Warm-Up Routine
Perform this warm-up routine before your main training session:
- On a comfortable firm surface, in a seated position, slide deflated Back-Unit (black tubing will be to your right side) against low back and buttocks.
- Gently lean back and over deflated Back-Unit. Buttocks should hang off edge of Back-Unit. Move the Back-Unit slightly up or down, left or right to locate the most centered and comfortable position for you.
- While lying flat on Back-Unit, with knees bent and feet firmly on the ground, rock pelvis up and back toward belly button using abdominal muscles to lift buttocks.
- Then rock downward using back muscles and allow lower back to gently stretch over air cells, lowering buttocks to floor. Repeat this movement several times to conclude warm-up routine. Never rock Back-Unit with Neck-Unit inflated (if so equipped).

Troubleshooting
If you encounter any issues while using your Posture Pump® Penta Vec® Model 2500, please refer to the following general advice:

- Loss of air pressure: Inspect the air bladders and hoses for any punctures or leaks. Ensure all connections are secure.
- Discomfort during use: Re-evaluate your setup and adjustments. Ensure the pelvic and foot-unit belts are not too tight or too loose. Reduce the inflation level of the air cells. If discomfort persists, discontinue use and consult a healthcare professional.
