There are many names for hypertonus diagnoses involving these symptoms including: levatores ani syndrome (Nicosia, 1985; Salvanti, 1987; Sohn, 1982), tension myalgia (Sinaki, 1977), proctalgia fugax (Swain, 1987), coccygodynia (Dittrich, 1951; Thiele, 1937; 1963; Waters, 1992), dyspareunia (Glatt, 1990), vaginismus (Hall, 1952), animus, vulvodynia (MacLean, 1995; Marinoff & Turner, 1992; Reid, 1993; Secor, 1992), vulvar vestibulitis (deJong, 1995; Spadt, 1995), interstitial cystitis, pudendal neuralgia (Turner, 1991), pelvic pain (Baker, 1993), and urethral syndrome (Steege, Metzger, & Levy 1998).
Muscle weakness is measured in the levatores ani, obturator internus, gluteus medius, iliopsoas, adductor, and lateral hip rotator muscles.
If deeper pain occurs, adhesion of the vaginal canal, adhesive disease, cervix and uterine dysfunction, levatores ani muscle trigger points, or sacroiliac and symphysis pubis joint dysfunction may be involved.
Addressing hypertonus in the levatores ani, particularly the pubococcygeus and iliococcygeus (DeFranca, 1996), iliopsoas (Headley, 1997; Lee, 1999), piriformis, adductors (Costello, 1998), quadratus lumborum, hamstrings, obturator internus, coccygeus, and gluteus medius (Lee, 1999) are essential for complete treatment of this region (see Tables 7, 8, & 9).
Trigger points from the adductors, rotators, and levatores ani muscles can elicit referred pain elsewhere (Costello, 1998; Travell & Simons, 1992).
