Patient-Reported Prevalence, Characteristics, and Impact of Leg Cramps in an Urban Primary Care Clinic.

Abstract

This study addresses the prevalence and characteristics of leg cramps in 294 primary care patients (mean age = 46.5 years), with 51.7% reporting leg cramps. Patients who experience resting or exercise-induced leg cramps were more likely to be older and female. Cramp severity averaged 5.6 on a scale of 1-10 and disturbed sleep "sometimes" or "often" in 55% of patients. Most patients did not discuss cramps with their clinician. Our study reveals a possible shift in patients who experience leg cramps to younger age and chronicity. Resting leg cramps should be reviewed by clinicians as a symptom of declining health and advancing aging.
