What is considered normal vs abnormal vaginal muscle tone?
Normal vaginal muscle tone allows for both flexibility and support, maintaining continence and sexual function. Abnormal tone refers to muscles that are either too weak (laxity) or too tight (hypertonicity), causing symptoms or functional problems.
Detailed Medical Explanation
Normal tone means the pelvic floor muscles contract and relax appropriately, supporting pelvic organs and responding during physical activities and intimacy. Abnormal tone includes hypotonicity (weakness or laxity) and hypertonicity (over-tightness or spasm). Symptoms of abnormal tone include incontinence, prolapse, pain, discomfort, or reduced sexual satisfaction. Diagnosis is clinical, with assessment by a pelvic health physiotherapist or gynaecologist.

Clinical Context
Assessment of tone is tailored to the individual, considering age, childbirth history, and symptoms. Both excessive laxity and tightness can be treated with physiotherapy and, where needed, specialist referral.
