A study of nearly 2,000 adults who underwent inpatient surgery found that higher daily step counts after surgery were associated with fewer complications, fewer 30-day readmissions and shorter hospital stays. The observational findings show an association, not proof that walking caused better outcomes.
A study of nearly 2,000 adults who had inpatient surgery found that patients who walked more each day after their operations than they had before surgery were less likely to experience complications or be readmitted within 30 days. Published online May 6, 2026, in the Journal of the American College of Surgeons, the observational study also linked increased walking with shorter hospital stays, but it does not establish that walking caused those outcomes.
Researchers analyzed data from a National Institutes of Health research program, including adults who had various 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 patients’ postoperative activity with their own average presurgery step counts.
For every additional 1,000 steps per day above a patient’s presurgery average, the analysis 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. Those percentages describe associations reported by the study, not guaranteed benefits for an individual patient.
The report summarized by Seniors Guide, citing Harvard Health writer Lynne Christensen, notes that recovery varies with factors including the operation, a person’s overall health and whether complications occur. The study was observational, so differences in patients’ health or recovery may help explain the results. It cannot show that adding steps by itself produced the lower risks.
Step Counts and Recovery Outcomes
The findings add a measurable association to the established practice of encouraging patients to move when it is safe after surgery. Early mobility is used in medical care because it may help limit problems such as lung complications, blood clots and weakness, and may reduce prolonged hospital stays. The study’s comparison with each patient’s own presurgery activity offers one way to describe postoperative walking rather than applying a single step target to everyone.
For patients and care teams, step counts could provide a practical indicator of activity and recovery progress. A wearable device may help patients track whether their movement is increasing and help clinicians identify people who may need additional support. But the study does not set a safe or effective daily step goal, and it does not establish that everyone should increase activity at the same rate.
The results matter because complications and readmissions can affect patients’ health and add to the demands on hospitals. Still, the reported associations should be read as evidence that walking levels and outcomes tracked together in this group—not as proof that walking alone prevents complications or readmission.

Why Hospitals Encourage Early Movement
Surgery places physical stress on the body, and recovery time depends on the procedure, overall health and any complications. As part of recovery care, medical centers commonly encourage patients to start walking as soon as it is safe. The purpose is to support mobility and reduce risks associated with remaining inactive, while taking account of a patient’s condition and surgical instructions.
The 2026 analysis contributes to a body of research that, according to the source report, has also linked more walking after surgery with fewer complications. Its particular approach compared postoperative step totals with patients’ own presurgery averages. That makes the results relevant to changes in activity, but it does not replace individualized advice from a surgical team or establish a universal threshold.
““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, which means it can identify relationships in the data but cannot prove that more walking caused fewer complications, readmissions or shorter stays. Patients able to walk more may differ in health, procedure, recovery progress or other ways from those who walked less. The source report does not provide enough detail to determine how fully the analysis accounted for such factors.
The available account also does not specify the exact types of surgery represented, the number of steps patients took, or whether the associations differed across operations or patient groups. It gives no universal postoperative step goal. The findings should not be interpreted as a reason to walk through pain, disregard restrictions or increase activity without clinical guidance.

Follow Surgical Team Guidance
No further study milestone or clinical guideline change is reported in the source material. For now, patients should ask their surgical team when and how to increase activity, since safe movement depends on the operation and their recovery. If a wearable step counter is used, its readings can be discussed with clinicians as one measure of activity—not as a substitute for medical assessment.
Further research would be needed to clarify whether increasing steps directly improves outcomes, which patients might benefit most, and what activity levels are safe after different procedures. Until then, the study supports an association between more postoperative walking and better reported outcomes, while leaving individual targets to clinical judgment.

Key Questions
What did the study find about walking after surgery?
In nearly 2,000 adults after inpatient surgery, each additional 1,000 daily steps above the patient’s presurgery average was associated with a 17% lower chance of complications and a 15% lower likelihood of readmission within 30 days. More walking was also linked to shorter hospital stays.
Does the study prove that walking prevents complications?
No. It was an observational study, so it found associations but could not establish that walking caused the outcomes. Other differences among patients may have contributed.
How many steps should someone take after surgery?
The report does not provide a universal step goal. Safe activity depends on the procedure and the individual’s recovery, so patients should ask their surgical team when and how to increase walking.
Can a wearable tracker help during recovery?
A step-counting device can help track activity and may give a care team information about a patient’s movement. The source report presents it as a possible monitoring tool, not as a substitute for clinical guidance.
