Brief Summary

The current practice to avoid incisional hernia, one of the most frequent complications following abdominal surgery, is to minimize core muscle activity in the postoperative phase. However, there is no evidence to support the association of core muscle activity and increased incidence of incisional hernia. On the contrary, it is likely that reduced physical activity could lead to physical deconditioning, chronic postsurgical pain (CPSP), and sarcopenia. The investigators will conduct a prospective multicentric randomized clinical trial to compare standard of care to core muscle exercises targeting the abdominal muscles immediately postsurgery. The principle hypothesis is that neither specific exercises of core muscles before and after surgery nor physical restriction alter the incidence of incisional hernias. Secondly the impact of postoperative rehabilitation on CPSP and sarcopenia will be assessed.

Study Arms (2)

Control group

NO INTERVENTION

The patients in the control group will receive standard physiotherapy and will be instructed to limit core muscle activity and weight bearing according to their pain symptomatology. Standard physiotherapy for all hospitalised patients includes early mobilization and exercises to prevent thrombosis and pulmonary complications (atelectasis, pneumonia, diaphragmatic deconditioning), balance training and endurance and exercise training

Intervention group

EXPERIMENTAL

The patients in the intervention group will be given exercises to perform postoperatively.They will be instructed by a physiotherapist in how to perform the four specific exercises targeting core muscles. The patient will perform these exercises daily during hospitalization under the supervision of the physiotherapist and then at home for two months after the operation. The intensity of the exercises will be adjusted daily to the physical capabilities of the patient. They will also benefit from standard physiotherapy as described above.

Other: Physiotherapy

Interventions

4 specific core muscle exercises, targeting abdominal muscles, to be performed daily from postoperative day one to 2 months postsurgery.
