A study of nearly 2,000 adults found that each additional 1,000 daily steps after surgery, compared with a patient’s presurgical average, was associated with a 17% lower chance of complications and a 15% lower likelihood of hospital readmission within 30 days. The observational findings show an association, not proof that walking caused better outcomes.

A study published online May 6, 2026, found that adults who took more steps each day after inpatient surgery were less likely to experience complications or return to the hospital within 30 days. The analysis of nearly 2,000 patients also linked increased walking with shorter hospital stays, though its observational design cannot show that walking itself caused the differences.

Researchers analyzed data from a large National Institutes of Health research program, identifying adults who had undergone various types of inpatient surgery. Participants wore step-counting devices for at least seven days before surgery and for several weeks afterward on average, giving researchers a measure of activity before and after their procedures.

For every additional 1,000 steps per day above a patient’s average presurgical step count, the researchers found a 17% lower chance of complications and a 15% lower likelihood of hospital readmission within 30 days. Greater postoperative walking was also associated with shorter hospital stays. The report does not provide a specific number of days saved or details here about the kinds of complications recorded.

The findings were reported in the Journal of the American College of Surgeons. The study was observational: researchers examined patterns in patient data rather than assigning people to walk more or less. That distinction means the results describe an association and do not establish that raising step counts directly led to better outcomes.

Walking and Recovery Outcomes

The findings add evidence to a practical question for patients and care teams: how much does movement after an operation relate to recovery? The reported links between higher step counts and fewer complications, fewer readmissions and shorter stays suggest that daily activity may be a useful measure to monitor as patients recover.

Step counts could also help care teams notice when a patient is moving less than expected and may need additional support, according to the source report. But the study does not establish a target number of steps for all patients, nor does it show that every person should increase activity at the same pace. Recovery depends on factors including the operation, overall health and complications.

For patients, the central point is not to push through pain or follow a one-size-fits-all step goal. Medical centers already encourage patients to begin walking when it is safe, partly to help prevent problems such as lung complications, blood clots and weakness. Any change in activity after surgery should follow the surgical team’s guidance.

Why Hospitals Encourage Early Movement

Walking soon after surgery is already part of recovery practices at medical centers when a patient’s condition makes it safe. The source report says early mobility can help prevent problems such as lung complications, blood clots and weakness, and may help limit longer hospital stays. The timing and amount of movement depend on the type of surgery and the patient’s condition.

The new analysis builds on earlier studies that have also linked more walking after surgery with lower complication rates, according to the report. Its added detail is the comparison with each patient’s own average presurgical step count: the reported outcome differences were associated with each extra 1,000 daily steps above that baseline. The research covers different inpatient procedures, rather than establishing a specific recovery plan for one operation.

The article summarizing the study was written by Lynne Christensen, a staff writer for Harvard Health Publications, and published by Seniors Guide. The study’s journal and online publication date are identified in that report; the summary does not provide the full study title or additional methodological details.

““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’s observational design leaves open whether increased walking contributed to better outcomes or whether patients who were already recovering more smoothly were able to walk more. Other differences in patients’ health, procedures or recovery could also be related to both activity and outcomes. The report does not establish cause and effect.

The summary does not specify the patients’ average step counts, the absolute number of complications or readmissions, or how the researchers accounted for other factors that could influence recovery. It also does not give the size of the reduction in hospital stay. The reported percentages should be read as associations for each additional 1,000 steps over the individual’s presurgical average, not as guaranteed outcomes for a particular patient.

It is also unclear from the report whether the association applies equally across different operations, ages and health conditions. No universal postoperative step target is provided. When walking is safe, and how quickly to increase it, remain questions for the patient’s surgical team.

Guidance During Postoperative Recovery

The source report does not identify a planned follow-up study, a new hospital policy or a recommended step-count threshold. For now, the practical next step it describes is for patients to ask their surgical team when activity can safely increase and what level is appropriate for their procedure and recovery.

Patients using a wearable step counter may be able to share activity trends with their health care team, which the report says can help identify when additional support may be needed. A device can track movement, but it does not determine whether a particular level of activity is medically appropriate. The study’s findings will need to be interpreted alongside a patient’s operation, health and recovery progress.

Key Questions

What did the study find about walking after surgery?

In an analysis of nearly 2,000 adults after inpatient surgery, each additional 1,000 steps per day 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 more steps cause better recovery?

No. The study was observational, so it can identify links between step counts and outcomes but cannot establish that walking caused the differences. Patients who recover more easily may also be able to walk more.

How many steps should I take after surgery?

The report does not set a universal step goal. The safe amount and timing of activity depend on the operation and the patient’s condition. Ask your surgical team when it is safe to begin increasing activity and what pace to follow.

Can a wearable tracker help during recovery?

A step-counting device can track activity over time and may help patients and care teams discuss whether movement is increasing or whether additional support is needed, according to the report. It does not replace individual medical guidance or determine what level of walking is safe.
