Kinesiology Tape, often called KT Tape, is a flexible, elastic therapeutic tape designed to mimic the elasticity of human skin. This specialized tape is used to provide support to muscles and joints without restricting the body’s range of motion. Diastasis Recti (DR) is a common condition, particularly postnatally, involving the separation of the rectus abdominis muscles. This article explores how KT Tape is used as an external support tool for this condition.
Understanding Diastasis Recti
Diastasis Recti occurs when the two vertical bands of the rectus abdominis muscles separate, creating a gap down the center of the abdomen. This separation is caused by the stretching and thinning of the linea alba, the connective tissue that runs vertically between the muscles. The primary cause is excessive outward pressure on the abdominal wall, most commonly seen during late pregnancy as the uterus expands.
The condition is a stretching of the midline tissue, not a muscle tear. Symptoms often include a visible bulge or “doming” when engaging the abdominal muscles, core instability, and lower back pain. While DR is most common in postpartum women, it can also affect men and infants due to factors that cause high intra-abdominal pressure.
The Mechanics of KT Tape Support
The role of KT Tape in managing Diastasis Recti is primarily mechanical and neurological, not curative. The tape is applied across the separated muscles to provide gentle external support, which acts to approximate the rectus abdominis muscles toward the midline.
The tape also provides continuous sensory input to the skin, acting as proprioceptive feedback. This gentle tug stimulates the nervous system, improving body awareness and encouraging the user to engage deeper core muscles, such as the transverse abdominis. The tape offers a tactile cue, reminding the wearer to maintain better posture and prevent excessive outward pressure during movement. Some studies suggest this support can lead to immediate improvements in abdominal endurance and stability.
Step-by-Step Application Guide
Successful application requires clean, dry skin and strips of tape with rounded edges to prevent premature peeling. Cut several strips of tape to the length of the separation, typically from just below the sternum to the pubic bone. The user should lie down with the abdominal muscles relaxed to ensure the separation is visible.
The application process involves several steps:
- Apply a vertical anchor strip with zero tension at the top of the separation, either on the side or directly above the rectus muscle.
- Peel the backing off a horizontal strip.
- Gently draw the separated muscles toward the center with the hands.
- Apply a light to medium stretch (roughly 25% tension) across the midline.
- Place the ends, or anchors, of this horizontal strip on the outer edge of the rectus muscle with no tension.
- Repeat this process every few inches along the length of the separation, often in a criss-cross or basket-weave pattern.
- Rub the tape vigorously for 30 to 60 seconds to activate the heat-sensitive adhesive, ensuring a secure bond that can last for two to three days.
Avoid applying the tape directly over the belly button, especially if it is protruding, to maintain comfort.
Efficacy and Professional Limitations
While KT Tape can offer immediate support, it is considered an adjunctive therapy, not a primary treatment for Diastasis Recti. Research indicates that kinesiology taping, particularly when combined with targeted core exercises, can significantly reduce the separation distance, especially above the umbilicus. Taping has also been shown to help decrease physical disability associated with low back pain, a common complication of abdominal wall weakness.
The tape does not permanently heal the stretched linea alba; it offers temporary stability and awareness. Improper application is a risk, as applying too much tension can increase intra-abdominal pressure and potentially worsen the condition. Consulting with a pelvic health physical therapist before using the tape is recommended to confirm the diagnosis and learn the correct application technique. People with sensitive skin, open wounds, or adhesive allergies should exercise caution or avoid using the tape entirely.
