Before you take part in this study, you will be asked to complete a survey about the amount of pain you are currently experiencing (the Brief Pain Inventory-Short Form). It should take about 10 minutes to complete the Brief Pain Inventory-Short Form. Completing the pain inventory before your surgery will allow for a better comparison of your pre and postoperative surgical and gas pain. You will be asked to provide some information such as your age and marital status that will be recorded on a coded data sheet. You will also receive an instruction sheet that describes what you need to do in order to participate in the study (Instruction to Subjects Sheet). The study investigator will also demonstrate to those chosen for the rocking group the correct method to rock in the rocking chair and allow them time to practice. He will also demonstrate the correct way to wear the gait belt with the pedometer attached to it.
