Studies were eligible if pelvic pain and PFM tone outcome measures were reported among women aged &amp;gt;18\u00a0years. The National Heart, Lung, and Blood Institute\u2019s Quality Assessment Tool for Observational Cohort and Cross-sectional Studies was used to assess study quality. Studies were pooled by assessment of PFM tone via a random effects model. Associations between the presence of pelvic pain and PFM tone were assessed with odds ratio (OR), while linear associations were assessed with Pearson or Spearman correlation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Outcomes<\/jats:title>\n                  <jats:p>Pelvic pain measures (intensity, threshold, and frequency) and resting PFM tone in women with PNCPP, as evaluated by any clinical assessment method or tool.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Twenty-four studies were included in this review. The presence of pelvic pain was significantly associated with increased PFM tone as assessed by digital palpation (OR,\u00a02.85; 95% CI, 1.66-4.89). Pelvic pain intensity was inversely but weakly associated with PFM flexibility when evaluated through dynamometry (r\u2009=\u2009\u22120.29; 95% CI, \u20130.42 to \u22120.17). However, no significant associations were found between pelvic pain and PFM tone when measured with other objective assessment methods.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Clinical Implications<\/jats:title>\n                  <jats:p>Pelvic pain and increased PFM tone may not be directly associated; alternatively, a nonlinear association may exist.
