IntroductionPreoperative exercise and fitness are predictors of surgical recovery; however, little is known of the effect of preoperative exercise-based conditioning, known as prehabilitation, in this for men undergoing radical prostatectomy. Our study examined the feasibility and effects of prehabilitation on perioperative and postoperative outcomes in men undergoing radical prostatectomy.MethodsThis feasibility RCT compared prehabilitation (PREHAB) versus a control condition (CON) in 86 men undergoing radical prostatectomy. PREHAB consisted of home-based, moderate-intensity exercise prior to surgery. Both groups received a preoperative pelvic floor training regimen. Feasibility was assessed via rates of recruitment, attrition, intervention duration and adherence, and adverse events. Clinical outcomes included surgical complications, and length of stay. The following outcomes were assessed at baseline, prior to surgery, and 4, 12, and 26-weeks postoperatively: 6-min walk test (6MWT), upper-extremity strength, quality of life, psychosocial wellbeing, urologic symptoms, and physical activity volume.ResultsThe recruitment rate was 47% and attrition rates were 25% and 33% for PREHAB and CON, respectively. Adherence to PREHAB was 69% with no serious intervention-related adverse events. After the intervention and prior to surgery, PREHAB participants demonstrated less anxiety (P = 0.035) and decreased body fat percentage (P = 0.001) compared to CON. Four-weeks postoperatively, PREHAB participants had greater 6MWT scores of clinical significance compared to CON (P = 0.006). Finally, compared to CON, grip strength and anxiety were also greater in the PREHAB at 26-weeks (P = 0.022) and (P = 0.025), respectively.ConclusionWhile feasible and safe, prehabilitation has promising benefits to physical and psychological wellbeing at salient timepoints relative to radical prostatectomy.Copyright © 2018 Elsevier Ltd.
