Interventions	I (43): oxybutynin, 2.5 mg BD, up to 5 mg TDS, orally II (43): TENS, 20 HZ, 6 hours daily After 6 weeks of treatment in the first arm, patients were re‐assessed. Patients completed a post‐treatment side effects questionnaire. After a washout period of 2 weeks, patients were started on the second arm of treatment, and the same assessment was repeated after 6 weeks of treatment Total duration of study: 14 weeks
Outcomes	Numbers not improved during treatment: I: 20/40, II: 20/38 Number of voids per day N, mean (SD): I 43, 9 (SD 5), II 43, 9 (SD 4), P≤0.003 compared with baseline of 43, 11 (SD 5) Number of incontinence episodes: "no statistical difference between treatment arms" Number of micturitions per day: "statistically significant (p< 0.0001)" compared with baseline QoL: "No statistical difference found in any of the parameters of SF‐36" Adverse events: dry mouth, blurred vision, dry skin and skin irritation
