Blockage of the sacroiliac joint

Pain above the buttocks is often due to a blockage of the sacroiliac joint. Special exercises can alleviate sacroiliac joint pain.

In the kyBoot/on the kyBounder, you can gently mobilise the sacroiliac joint and simultaneously strengthen the musculature around the sacroiliac joint, thereby doing something about your problem on your own.


The right and left sacroiliac joints/iliosacral joints form the moveable connection between the sacral bone (os sacrum) and the ilium (os ilium).

The sacroiliac joint is a tight joint that is not very mobile and has a close-fitting joint cavity.

Fractures and luxations of the sacroiliac joint can occur due to falling, abrupt movements and twisting of the pelvis. Acute and chronic inflammation is possible.

A sacroiliac joint blockage occurs when the mobility of the already tight joint is restricted further or when the position of the joint surfaces relative to each other deviates from the norm.

A sacroiliac joint blockage can occur in both men and women of any age. Around 70 per cent of the German population suffers from a sacroiliac joint blockage (blocked iliosacral joint) at least once in their life.


  • In most cases, a sacroiliac joint blockage is caused by lifting objects that are too heavy, incorrect lifting or stepping into a void, for example when missing a step or when stumbling on uneven ground.
  • Certain spinal column problems can increase the risk of developing a sacroiliac joint blockage. Furthermore, operations on the musculoskeletal system, for example on the knee or hip joint, can lead to an imbalance in the area of the sacroiliac joint and therefore to a sacroiliac joint blockage.
  • A poor, one-sided body posture (e.g. working on the computer) can lead to twisting of the pelvis, therefore increasing the risk of sacroiliac joint blockage.

Long-term consequences

A one-sided or non-physiological body posture leads to excessive strain on the back. When excessive strain is placed on the back, it responds over time with pain or blockages that can later lead to chronic pain, wear (e.g. herniated discs) or problems in other body regions.

Conventional therapy

  • Several therapy options are available for a blocked sacroiliac joint. In many cases, the blocked joint is mobilised or manipulated by a therapist.
  • Muscular stabilization training is subsequently required so that the joint does not become blocked again.
  • Other therapeutic measures, such as heat application (e.g. hot roll)

The kybun principle of operation – being proactive

With the kyBoot/kyBounder, the joint is mobilised in a subtle, differentiated manner. The core joint stabilizing musculature is strengthened, providing long-term therapy for the joint and thereby preventing a relapse.

Muscle strengthening and stretching in the kyBoot
The kyBoot has a soft, elastic sole that does not limit foot mobility but provides full freedom for unrestricted movement in all directions. Standing on the soft, elastic surface with the associated instability in the kyBoot trains the muscular system and straightens the body. A one-sided relieving posture is prevented. The load on both sides of the body is even, which counteracts tension. The foot can move freely while walking as nature intended. By eliminating the heel, the foot sinks deep into the sole even on a hard, flat surface. This stretches and relaxes the muscles.

Upright posture on the kyBounder
Sitting for long periods of time, especially with poor posture, puts one-sided strain on the muscles and spinal column. Underused muscles get weaker and shorten over time. On the other hand, muscles under excessive one-sided strain respond by tensing up. Neck, hip, and back pain (especially blockages of the sacroiliac joint) are the result and lead to further malpositions.

The muscles are stretched, relaxed and trained on the soft, elastic mat of the kyBounder, which brings the body into a natural, upright posture. This releases tension and imbalances. The standing and posture muscles are strengthened in a targeted manner. Back pain can be alleviated and blockages released by alternately tensing and relaxing the muscles.

Initial reactions

Specific initial reactions with existing back problems/back pain:

If you are not yet accustomed to the kyBoot or have been suffering from back/sacroiliac joint problems for some time already, you may experience increased pain in the kyBoot in the beginning. The still weak or shortened hip, buttock and back musculature is one cause. Walking in the kyBoot or on the kyBounder, your body assumes a new posture. You stand more upright than previously in ‘normal’ shoes with their stiffer soles. This is a new challenge for your body, which first has to get used to the change in pressure distribution.
If you perceive new, unfamiliar pain in the area of the pelvis with the kyBoot, this is a sign that the kyBoot still represents a challenge for your body. In this case we advise performing the kybun exercises and, if this no longer helps, taking a short kybun break so the sacroiliac joint can recover.
Gentle walking in the kyBoot/standing on the kyBounder mobilises the sacroiliac joint. The initial reactions will go away, allowing you to walk ever longer distances in the kyBoot.

Application tips

If you experience pain in the area of the buttocks in the kyBoot or on the kyBounder, or if your familiar sacroiliac joint complaints get worse, this may be due to various reasons (e.g. tense muscles, movements that are unfamiliar for the back).

We advise you to perform the kybun exercises regularly every now and again. These loosen your musculature and you are less likely to fall into a passive position that puts strain on the sacroiliac joint.

If you get very fatigued in spite of the kybun exercises, if you feel pain or in case of lateral/medial rolling of the ankle joint on the kybun sole, we advise you to take a short kyBoot/kyBounder break until the symptoms go away.

Choose a kyBoot shoe with the slightly wider second generation sole. It provides you with greater midfoot stability. Ask your kybun dealer to show you the various models.

Be sure to maintain an upright posture, avoid taking excessively long stepsandkeep your gaze forward(do not look at the floor). You should walk straight on the kyBoot sole and correct any lateral/medial rolling of the ankle joint!

Should your back pain continue even though you are following the application tips, please seek advice from your kybun dealer.
