A study published online May 6, 2026, found that adults who walked more after inpatient surgery had lower rates of complications and 30-day readmission. The observational findings show an association, not proof that more steps caused better recovery; patients should ask their surgical teams when activity is safe.
A study of nearly 2,000 adults who had inpatient surgery found that higher daily step counts after their procedures were associated with fewer complications and hospital readmissions. Published online May 6, 2026, in the Journal of the American College of Surgeons, the observational research adds evidence that walking may be linked to recovery outcomes, but it cannot establish that walking caused the improvements.
Researchers analyzed data from a large National Institutes of Health research program. The participants had undergone different types of inpatient surgery and wore step-counting devices for at least seven days before their procedures and for several weeks afterward, on average. The study compared postoperative activity with each patient’s average presurgical step count.
For every additional 1,000 steps per day above that average, researchers found a 17% lower chance of complications and a 15% lower likelihood of being readmitted to the hospital within 30 days. Higher postoperative step counts were also associated with shorter hospital stays. Those percentages describe the study’s reported associations; they do not mean that increasing steps will produce the same reduction for every patient.
The report was written by Lynne Christensen, a staff writer for Harvard Health Publications, and distributed by Tribune Content Agency. Its practical advice is to ask the surgical team when it is safe to increase activity. The results do not set a universal step target or override instructions based on a patient’s procedure and condition.
Walking and Recovery Outcomes
The findings matter because walking is already used as part of recovery care: medical centers encourage patients to begin moving as soon as it is safe. Early mobility can help prevent problems such as lung complications, blood clots and weakness, and may help reduce longer hospital stays, according to the source report.
Step counts could give patients and care teams a practical way to observe activity after discharge or during recovery. The study suggests that increases relative to a person’s own presurgical activity may be associated with better outcomes. But the research does not show that setting a higher target will itself prevent complications or readmission. Patients’ recovery needs vary, and activity should follow individual medical guidance.

How the Step Counts Were Compared
The study examined activity both before and after surgery, rather than comparing patients against one fixed daily step goal. Its reported association was calculated for each additional 1,000 daily steps above a patient’s presurgical average. Participants had a range of inpatient procedures, and post-surgery monitoring lasted several weeks on average.
Starting to walk soon after an operation is part of care at many medical centers, but timing and safe activity levels depend on factors including the type of surgery, overall health and any complications. The report also points to earlier studies linking more walking after surgery with fewer complications. It does not provide details about those studies or establish that the new findings apply equally to every operation or patient group.
“For every additional 1,000 steps patients made each day over their average presurgical step count, researchers found a 17% lower chance of complications and a 15% reduced likelihood of being readmitted to the hospital within 30 days.”

Limits of the Recovery Findings
Because the study was observational, it can show that step counts and outcomes were associated but cannot determine whether more walking caused fewer complications, readmissions or shorter stays. Other differences among patients may help explain the results; the report does not specify which factors researchers adjusted for.
The source material does not give the study’s full methods, participant characteristics, exact average step counts or absolute rates of complications and readmission. It also does not identify a safe daily step target, establish how much activity is appropriate after particular procedures, or say whether the association differs by surgery type. Those details would be needed to judge how directly the results apply to an individual patient.

Follow Surgical Team Guidance
The immediate practical step for patients is to ask their surgeon or care team when walking can safely begin and how activity should increase during recovery. A wearable device may help track progress, and the report says this information can help health care teams identify patients who may need additional support.
The source material does not announce a follow-up trial or a planned change to clinical guidance. Further research would be needed to test whether deliberately increasing steps improves outcomes and to clarify suitable targets for different procedures and patients. Until then, the findings support discussion with a care team—not a one-size-fits-all step prescription.

Key Questions
Did the study prove that walking more prevents surgical complications?
No. It was an observational study, so it found an association between higher step counts and outcomes but cannot prove that walking caused fewer complications.
What did the study report about additional steps?
For each additional 1,000 steps per day above a patient’s average before surgery, researchers found a 17% lower chance of complications and a 15% lower likelihood of readmission within 30 days. These are reported associations, not guaranteed individual benefits.
How soon should someone start walking after surgery?
The report says medical centers encourage early movement when it is safe. The right timing depends on the operation and the patient’s condition, so patients should ask their surgical team.
Did the study recommend a daily step goal?
No specific universal target is given in the source material. The comparison was based on each participant’s own average presurgical step count.
