Kegel Training Directly Targets the Levator Ani Muscles
Kegel exercises (pelvic floor muscle training) directly target the levator ani muscles, which include the puborectalis, pubococcygeus, and iliococcygeus muscles, along with the coccygeus muscles. 1
Anatomy of the Pelvic Floor Muscles
- The pelvic floor consists primarily of the levator ani muscle group, which forms a supportive hammock for the pelvic organs 2, 1
- These muscles provide crucial support to the bladder, urethra, uterus (in women), and rectum 1
- The levator ani muscles include:
- Puborectalis muscle
- Pubococcygeus muscle
- Iliococcygeus muscle
- The coccygeus muscles are also part of the pelvic floor musculature 1
Clinical Applications of Kegel Exercises
- Kegel exercises involve voluntary contractions of the pelvic floor muscles to improve strength, power, endurance, and relaxation of these muscles 1
- They are primarily recommended as first-line treatment for urinary incontinence, particularly stress urinary incontinence 2, 1
- During Kegel exercises, patients are instructed to contract their pelvic floor muscles for 6-8 seconds with 6 seconds of rest between contractions 3
- These exercises are typically performed twice daily for about 15 minutes per session 3
Assessment and Proper Technique
- Proper technique is crucial for effective Kegel exercises - simple verbal or written instruction is often inadequate 4
- In one study, after brief verbal instruction, only 49% of women performed an ideal Kegel contraction with increased urethral closure force without Valsalva maneuver 4
- 25% of women actually performed the exercise incorrectly in a way that could potentially worsen incontinence 4
- Clinicians should ensure patients can correctly identify and contract the levator ani muscles without activating abdominal, gluteal, or thigh muscles 1, 4
Effectiveness and Clinical Evidence
- Pelvic floor muscle training has been shown to significantly reduce urinary leakage in women with stress urinary incontinence 3, 5
- Studies demonstrate that consistent Kegel exercises can improve quality of life scores and reduce the severity of urinary incontinence 3, 6
- Kegel exercises can be performed with or without assistive devices, with both approaches showing effectiveness for urinary incontinence improvement 3
- Advanced techniques include using biofeedback or resistance devices to enhance training effectiveness 3, 6
Imaging Assessment of Pelvic Floor Function
- Dynamic imaging techniques can assess pelvic floor muscle function during Kegel contractions 2
- Transperineal ultrasound (TPUS) can evaluate pelvic floor function during rest, strain, and Kegel maneuvers 2
- MRI can reliably measure muscle thickness and detect levator muscle defects that may affect the success of Kegel exercises 2
Common Pitfalls and Recommendations
- Patients often contract the wrong muscles (abdominal, gluteal, or thigh muscles) instead of the pelvic floor muscles 4
- Valsalva maneuver during attempted Kegel exercises can worsen incontinence 4
- Pelvic floor strengthening exercises (Kegels) should be avoided in patients with pelvic floor tenderness, as they may worsen symptoms 2
- For patients with pelvic floor tenderness, manual physical therapy techniques may be more appropriate than Kegel exercises 2
