Methods Randomised: yes
Participants Recruitment: Pre‐operative
Included: radical prostatectomy, all men
Age: Group A 48 to 68 years, Group B 49 to 72 years
Interventions Intervention: post operative
Group A (38) intervention: instructions on PFMT and physiotherapy, 45 minutes weekly. Patients were instructed to perform 3 sets of contractions daily at home, in either a supine, sitting or standing position. Digital anal palpation to teach correct contractions, as well as oral and written instructions
DVD of instructions given to those living too far from hospital
Group B (42) control: instructions on PFMT alone
Duration of treatment: up to 1 year
Length of follow‐up: 3, 6 and 12 months
Outcomes Self‐reported continence (not using pads)
3 months: A 16/35 (46%), B 17/40 (43%), P = 0.73
6 months: A 27/34 (79%), B 22/38 (58%), P = 0.061
12 months: A 33/36 (92%), B 28/39 (72%), P = 0.028
24 hour pad test: g/24hrs, mean (range)
3 months: A 17 (0‐282), B 7 (0‐46), P = 0.53
6 months: A 9 (0‐203), B 2 (0‐12), P = 0.73
12 months: A 2 (0‐55), B 1 (0‐14), P = 0.95
PFM strength (anal squeeze pressure, cm H2O), mean (SD)
3 months: A 50.7 (23.9), B 55.7 (25.6), P = 0.398
6 months: A 56.1 (21.7), B 65.8 (27.0), P = 0.117
12 months: A 64.0 (24.0), B 71.5 (26.2), P = 0.237.
Notes No SDs
Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Norwegian University performed the computerised randomisation procedure immediately after pre‐operative test
Allocation concealment (selection bias) Low risk Norwegian University performed the computerised randomisation procedure immediately after pre‐operative test. Urologist no prior knowledge of randomisation procedure
Blinding of participants (performance bias) High risk Blinding to intervention not possible
Blinding of personnel (performance bias) High risk Blinding to intervention not possible
Blinding of outcome assessment (detection bias) 
 All outcomes Unclear risk No information. Therefore judged to be unclear risk
Incomplete outcome data (attrition bias) 
 All outcomes High risk Drop out rate was 6% Four lost to follow up in physiotherapy group, one lost in instructions only group
Selective reporting (reporting bias) Low risk Outcomes in methods reported
Financial support Low risk "The work was funded by The Norwegian Fund for Postgraduate Training in Physiotherapy and The Norwegian Cancer Society"
Approved by medical ethics committee Low risk "The study was approved by the Regional Committee for Medical and Health Research Ethics"
Informed consent Low risk "Eighty‐five men provided written informed consent"
ITT analysis Low risk Assumed from patient flow chart
