Help your horse move easier and recover from SI pain or pelvic instability. This protocol guides you with clear, step-by-step EquiTecs taping for sacroiliac support, muscle relaxation, and healthy pelvic alignment. All your education and supplies, bundled together for an easier path to progress.

Protocol:

Begin with the Basics Course to learn proper tape handling, stretch, and technique. For SI joint dysfunction, progress to the Certification Course for advanced support applications, or the Applications Library for the SI Support application.

• Use the SI Support application as demonstrated in the Certification Course or Applications Library. 
• For general SI soreness or instability, apply the SI Support application along the sacroiliac region, following the anatomical landmarks as taught in the course.
• For severe cases, combine the SI Support application with the Lumbar/Hind-end Support or Back decompression application (Application Library) for additional stabilization and decompression.
• If muscle strain or asymmetry is present, combine with the Back Muscle Relaxation and Decompression techniques targeted over problem areas.

For chronic or recurring SI issues, use the Fascia Chain application along the affected fascia lines after the main protocol to address adhesions and dehydration.

When to Use:

• For horses diagnosed with sacroiliac dysfunction, SI pain, pelvic instability, or related hind-end soreness (always after veterinary assessment and diagnosis)
• As part of a recovery, management, or performance plan
• To support pelvic alignment, relieve muscle tension, reduce pain, improve comfort, and promote healthy movement
• For horses in heavy work, showing signs of SI soreness, or in postural retraining programs

How Long to Tape:

• For acute issues, use until all signs of pain, heat, and muscle tension have resolved (re-evaluate every 7–10 days)
• For chronic or recurring SI problems, use during flare-ups, periods of increased activity, or as part of ongoing management
• Leave the tape on until it loses its recoil, becomes loose, or collects debris underneath
• For severe or chronic SI issues, a 6–8 week period of continuous use is often required to re-pattern muscle memory and support long-term healing
• For post-chiropractic support, start the application 1–2 weeks before adjustment to remove deep inflammation, and continue use for 6 weeks to re-pattern muscle memory

For Chronic Cases:

For ongoing SI issues, follow the above protocol for 6–8 weeks, then use the Fascia Chain application for 2 weeks along the affected fascia lines to address and prevent fascia adhesions and dehydration. Afterward, restart the appropriate SI protocol as needed. Once the issue is resolved, repeat the Fascia Chain application for 2 weeks to ensure complete fascia rehabilitation. Coordinate with your veterinarian/chiropractor for ongoing assessment and adjustment.

SI Joint Management Note:

• Always rule out saddle fit issues, hoof imbalance, and underlying lameness
• Hock and stifle problems can cause SI pain and instability, and vice versa
• Underdeveloped core and gluteal muscles can contribute to SI instability and pain
• Use chiropractic when needed for pelvic and spinal health
• Encourage natural head/neck positions and turnout to promote pelvic relaxation
• Feed horses on the ground to prevent shortening of the long back and gluteal muscles
• Provide a balanced diet with adequate protein, minerals, and vitamin E
• Document response to taping and adjust protocols as needed
• For equine athletes: Using the Hind-end to Core & Thoracic Sling applications during conditioning and relaxed rides will promote core muscle development, self-carriage, and a more stable, rounded pelvis and topline

Clinical Reasoning:

These protocols increase circulation and lymphatic flow to the SI region, relieve muscle tension, and reduce pain. Decompression and muscle relaxation techniques restore normal movement patterns, while SI and advanced back applications stabilize the pelvis and support tissue healing. The Fascia Chain application prevents long-term dysfunction by restoring fascia health along the SI and back lines. Consistent use supports muscle memory, pelvic stability, and overall comfort, reducing the risk of recurrence. Strict adherence to these protocols provides the best prognosis for full recovery and rehabilitation.
