5 Top Reviewed SI Joint Belts for Sacroiliac Joint Dysfunction

Hpfy Article image

The SI joint belt helps support and stabilize the sacroiliac joint by restricting the excessive movement of the joint. The sacroiliac belt is a supportive brace that can help alleviate pain, reduce inflammation, protect from further injuries, and restore normal function of the SI joint. Sacroiliac belts are typically prescribed to mitigate pain and improve load transfer in individuals with SI Joint injuries, sacroiliac joint dysfunction, and sciatica. The SI joint belt is also helpful in curbing hip, pelvic, and SI joint pain during pregnancy.  

The sacroiliac (SI) joint is the joint between the sacrum and the ilium bones. There are two SI joints in your lower back, located on either side of the spine. The main job of the SI joint is to appropriately transfer the load from the upper body to the lower body when you stand or walk. Additionally, they serve as shock absorbers decreasing stress on the pelvis and spine.  

Symptoms of Sacroiliac Pain  

Symptoms of SI joint pain may include the following:  

  • Sharp, stabbing, or dull ache felt in the lower back or the back of the hip  
  • Difficulty walking or climbing stairs  
  • Feeling pain only on one side of your lower back, especially while lying   
  • Stiffness in the lower back when standing up after sitting for long periods or getting up from the bed in the morning  
  • Difficulty turning in bed, bending, twisting, or putting on shoes and socks  
  • Tenderness on touching the joint  

Causes of Sacroiliac Joint Pain  

The sacroiliac joint is incredibly tough and durable yet is still prone to structural damage from various possible sources. Strong ligaments help keep the SI joints in proper alignment and keep excessive motion in check. When these ligaments fail to provide adequate support, destabilization of the pelvis and SI joint can occur. Conditions that may place undue stress on the Si joint include:  

  • Arthritis   
  • Sacroiliac joint fractures  
  • Trauma or injuries to the ligaments that surround the SI joint  
  • Sacrum tilted out of normal anatomical position  
  • Inequality in leg length that disrupts walking patterns  
  • SI joint infection  
  • Obesity   
  • Pregnancy  

SI joint pain can be debilitating and interfere with your daily life. Usually, conservative therapies can provide relief from sacroiliac joint pain. Your doctor may recommend physical therapy exercises, non-steroidal anti-inflammatory drugs (NSAIDs), or a SI joint belt to ease pain and inflammation. A sacroiliac belt is designed to limit the movement of the SI joint to reduce painful symptoms. Here, we have listed the top 5 SI belts that will provide the support and comfort you need while recovering from sacroiliac joint dysfunction.
