A study published May 6, 2026, found that patients who walked more after inpatient surgery had lower observed rates of complications and 30-day readmission. The observational findings show an association, not proof that walking caused the improved outcomes.
A study published online May 6, 2026, in the Journal of the American College of Surgeons found that adults who took more steps each day after inpatient surgery had lower observed rates of complications and hospital readmission. For every 1,000 additional daily steps above a patient’s average before surgery, researchers reported a 17% lower chance of complications and a 15% lower likelihood of readmission within 30 days; the observational study cannot show that walking caused those differences.
Researchers analyzed data from a large National Institutes of Health research program, identifying nearly 2,000 adults who had different types of inpatient surgery. Participants wore step-counting devices for at least seven days before surgery and for several weeks afterward, on average. The researchers compared each patient’s postoperative activity with that person’s average presurgical step count.
Alongside the lower observed rates of complications and readmission, more postoperative walking was associated with shorter hospital stays. The source report does not give a specific reduction in length of stay or detail how the analysis accounted for differences in patients’ health, operations or recovery needs. The results describe a relationship between recorded steps and outcomes, not a prescribed target for every patient.
The findings were summarized by Lynne Christensen, a staff writer for Harvard Health Publications, in a report distributed by Tribune Content Agency and republished by Seniors Guide. The study’s central comparison is relative to each participant’s own presurgical activity, rather than a universal daily step goal.
Walking and Postoperative Outcomes
The results add evidence to the clinical practice of helping patients move soon after surgery when it is safe. Early mobility is used in medical centers as one part of recovery care, and the source report says it may help prevent problems including lung complications, blood clots, weakness and prolonged hospital stays. The study’s associations suggest that step counts could offer one way to track activity and identify patients who may need additional support.
For patients and families, the findings are relevant because walking is a practical activity that can be monitored with a wearable device or other step counter. But they do not show that increasing steps on one’s own is safe for every operation or patient. Recovery plans depend on the procedure, a person’s overall health and possible complications; the research does not establish a step threshold or prove that more activity will improve an individual’s outcome.

How the Study Tracked Steps
Surgery places physical demands on the body, and the pace of recovery varies. The report says medical centers commonly encourage patients to begin walking as soon as it is medically safe, as part of efforts to reduce risks associated with immobility. That practice is distinct from asking all patients to reach the same number of steps.
In this study, activity was measured before and after a range of inpatient procedures. Researchers used each patient’s presurgical average as the reference point, then examined how postoperative step counts related to complications, readmission within 30 days and length of stay. The report presents the work as further evidence alongside earlier studies linking more walking after surgery with lower complication rates, but it does not supply details of those studies.
“How quickly and successfully you return to normal function depends on such factors as the type of surgery, your overall health, and whether any complications occur.”

Limits of the Step Count Findings
The study was observational, so it cannot determine whether walking more reduced complications and readmissions or whether patients with smoother recoveries were able to walk more. The source material does not provide details such as the types of complications counted, the patients’ procedure-specific results, the size of the change in hospital stays, or the statistical methods used to account for differences among participants.
It is also unclear from the report whether the association applies equally across all operations and levels of patient health. No safe or effective step target is established, and the findings do not mean patients should disregard restrictions or pain and mobility guidance from their surgical teams. The reported percentages are tied to each additional 1,000 daily steps above the presurgical average, not to a comparison with a stated universal baseline.

Discuss Activity With Your Surgical Team
The immediate practical step for patients is to ask their surgical team when and how to increase activity. Clinicians can account for the operation, recovery progress and any complications when advising on walking. The report also notes that step-counting devices may help patients track progress and help care teams see when a person could need more support.
Further research would be needed to test whether deliberately increasing postoperative steps causes better outcomes, and to identify suitable activity guidance for different procedures and patients. Until then, the study supports an association between more walking and better measured outcomes, while leaving individual activity decisions to patients and their care teams.

Key Questions
What did the surgical recovery study find?
Among nearly 2,000 adults who had inpatient surgery, each 1,000 additional daily steps above a patient’s presurgical average was associated with a 17% lower chance of complications and a 15% lower likelihood of readmission within 30 days. More walking was also associated with shorter hospital stays.
Does the study prove that walking prevents complications?
No. The study was observational, which means it found an association but cannot establish that walking caused the lower rates. Patients who recover more easily may also be more able to walk.
How many steps should someone take after surgery?
The report does not set a universal step goal. Patients should ask their surgical team when it is safe to start walking more and what activity level suits their procedure and recovery.
How did researchers measure activity?
Participants wore step-counting devices for at least seven days before surgery and for several weeks afterward, on average. Researchers compared postoperative steps with each person’s average before surgery.
