Evaluation of Nursing Effects of Pelvic Floor Muscle Rehabilitation Exercise on Gastrointestinal Tract Rectal Cancer Patients Receiving Anus-preserving Operation by Intelligent Algorithm-based Magnetic Resonance Imaging

Table 1

Training plan of comprehensive pelvic floor muscle exercise in the experimental group.

Training order	Training items	Training methods
Part 1	Abdominal respiration	Patients were instructed to place hands on abdomen, and keep abdominal muscles relaxed as they inhaled. After that, they were allowed to pause for 1 to 2 seconds. As they exhaled, abdominal muscles were contracted with the hands on abdomen declining. Each group of training lasted for 5 seconds and 5 groups of training needed to be completed every time.
Part 2	Abdominal massage	Patients were asked to lie on their backs and press tianshu, qihai, and guanyuan acupuncture points successively. Each acupuncture point was pressed by the thumbs for 1 minute. When the acupuncture points become swollen and get fever, the degree of pressure should remain the same. Massage strength should be changed from light to heavy gradually with a moderate rate. Besides, the vertical tension of the surgical incision should not be increased.
Part 3	Kegel motion	Specific methods were the same as those for the control group, and the exercise was performed 5 times.
Part 4	Cross-leg anus lifting motion	Patients were asked to remain decubitus or in the standing position and keep thighs crossed. Besides, perinaeum needed to be clamped by hips and thighs, and the muscles around anus needed to be tightened and lifted upward slowly and gradually. The above actions should be kept for 5 seconds, and then patients were allowed to relax for 10 seconds. The group of exercise was performed 5 times.
Part 5	Bridging anus lifting motion	Patients were asked to lie on their backs in bed with their knees bent and the soles of their feet pushing the bed. With heads, elbows, and feet as the supporting points, hips were lifted by pelvic floor muscles, and hip muscles, and perineal muscles were contracted. Patients needed to try their best to keep the above actions for 5 seconds, and then they were allowed to lower their hips and relax for 5 seconds. The group of exercises was performed 5 times.
Part 6	Leg motion	Tsusanli was pressed and kneaded for 1 minute with the thumbs.
		When the acupuncture points become swollen and get a fever, the degree of pressure should remain the same. After that, two legs were lifted in turns. Besides, the thighs were kept at a 90° angle to the bodies. With a good physical condition, two legs could be gradually lifted, which should be repeated 5 times.
