Supporting Clients with Sacroiliac Joint Pain: A Guide for Pilates Instructors

As a Pilates instructor, one of the most important skills you can develop is the ability to support clients with specific injuries or chronic pain conditions, such as Sacroiliac (SI) joint pain. SI joint pain is a common complaint that can significantly impact a person’s mobility, daily activities, and quality of life. However, with a thoughtful, educated approach, Pilates can be an effective method for managing and alleviating SI joint discomfort.
Understanding Sacroiliac Joint Pain
The sacroiliac (SI) joint connects the sacrum (the base of the spine) with the iliac bones of the pelvis. These joints play a crucial role in transferring the weight between the upper body and the lower body, stabilizing the pelvis and providing shock absorption during movement. When the SI joint becomes inflamed, or misaligned, it can result in pain, stiffness, and limited functional activities 
Common causes of SI joint pain include:

• Muscle imbalances: Tightness or weakness in the muscles surrounding the pelvis and lower back can contribute to SI joint dysfunction.
  
• Joint dysfunction: Misalignment or dysfunction of the joint itself may result from overuse, trauma, or poor posture.
  
• Pregnancy and postpartum: Hormonal changes and the physical demands of carrying a baby can cause laxity in the ligaments supporting the SI joint.
  
• Overuse or injury: Athletes or individuals with physical labor-intensive jobs are more prone to SI joint irritation due to repetitive movements or physical stress.
  

As a Pilates instructor, your role is to help your clients navigate their pain and improve their strength, stability, and mobility while being mindful of their condition.

Key Considerations When Working with Clients with SI Pain

1. Encourage Communication 
Always start with an open conversation with your client. Encourage them to share any details about their pain: When does it occur? Is it sharp or dull? What movements or positions exacerbate the discomfort? This information will help you tailor the session to meet their needs and avoid triggering pain.
2. Assess Posture and Alignment
One of the core principles of Pilates is posture awareness, and this is particularly important for clients with SI joint pain. Poor posture can exacerbate misalignments in the SI joint. As you guide your client through exercises, ensure that their pelvis is in a neutral alignment—neither tilted excessively forward (anterior pelvic tilt) nor backward (posterior pelvic tilt). Encourage the activation of the abdominal muscles to help support the pelvis and spine.
3. Focus on Pelvic Stability and Core Strength
A key focus in Pilates for SI joint pain should be strengthening the deep core muscles, including the transverse abdominis, pelvic floor, and multifidus. These muscles provide critical support to the SI joint and help stabilize the pelvis.
4. Correct Muscle Imbalances
Imbalances between the muscles that support the pelvis—such as the hip flexors, hamstrings, glutes, and adductors—can aggravate SI joint dysfunction. Use Pilates exercises that target these muscles in a balanced way, focusing on both strength and lengthening.
5. Avoid High-Impact or High-Stress Movements
For clients with SI joint pain, high-impact exercises, deep twisting, or movements that require a great deal of lateral flexion or extension should be avoided, especially in the acute phases of pain. These movements can exacerbate irritation in the SI joint. Instead, focus on controlled, slow, and mindful movements that promote stability.
6. Work Within Their Pain-Free Range of Motion 
It's essential to avoid pushing your client into any positions that cause discomfort or pain. Encourage them to listen to their body and work within a pain-free range of motion. If they experience sharp or sudden pain, stop the exercise and reassess. Many clients will have a range of motion that is slightly reduced in the SI joint area, so be patient and respectful of their limits.
7. Breathing for Relaxation and Control
Pilates places great emphasis on breath control, and this is doubly important for clients with SI joint pain. Diaphragmatic breathing can help your client relax their pelvic floor and abdominal muscles, aiding in pain reduction and promoting proper pelvic alignment. Teach them how to inhale into the ribcage and exhale to engage the deep core muscles without bracing.
8. Consider Modifying Positions
Some standard Pilates positions may place too much strain on the SI joint, especially in the prone or supine positions. You may need to adjust the height of the legs, add padding, or encourage slight adjustments in form to ensure comfort and safety. For example:

• In supine positions, consider placing a small cushion or ball under the client’s knees to reduce strain on the lower back and pelvis.
  
• In side-lying exercises, use a cushion between the knees for extra support and reduce any twisting force on the SI joint.
  

9. Educate Your Clients 
Educate your clients about the importance of maintaining pelvic stability throughout their daily activities. In addition to Pilates practice, encourage them to be mindful of their posture while sitting, standing, and walking. Proper body mechanics outside of the studio will complement the work done during your sessions and help prevent further irritation of the SI joint.

Sample Pilates exercises safe and indicated for SI Joint Pain:

• Pelvic Tilts
  
• Bridging
  
• Abdominal knee folds or 90/90 toe dips
  
• Quadruped bird dog 
  
• Side-Lying hip series (bent or straight leg)
  
• Functional double leg squats
  
• Plank variations 
  

Working with clients who have SI joint pain requires a balanced approach, focusing on strengthening the muscles around the pelvis, enhancing stability, and promoting proper posture. Pilates, with its emphasis on controlled movement and core stability, can be a powerful tool in helping clients manage and alleviate SI joint pain. 
By being mindful of your clients’ unique needs and limitations, you can create a safe and effective practice that supports their healing process and improves their overall quality of life.
