A study published May 6, 2026, in the Journal of the American College of Surgeons found that patients who walked more after inpatient surgery had lower rates of complications and 30-day readmission. The observational findings show an association, not proof that extra steps caused better recovery.
Patients recovering from inpatient surgery who took more daily steps than their usual presurgical average had lower rates of complications and hospital readmission, according to a study published online May 6, 2026, in the Journal of the American College of Surgeons. The researchers found that each additional 1,000 steps per day above a patient’s average before surgery was associated with 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 outcomes.
The researchers analyzed data from a large National Institutes of Health research program, identifying nearly 2,000 adults who underwent different types of inpatient surgery. Participants wore step-counting devices for at least seven days before surgery and for several weeks afterward on average, allowing the team to compare postoperative activity with each patient’s own baseline.
For every 1,000 additional steps per day above that presurgical average, patients had a 17% lower chance of complications and a 15% reduced likelihood of being readmitted within 30 days. More walking after surgery was also linked to shorter hospital stays, though the source report does not provide a specific estimate for the length-of-stay difference.
The results describe an association, not a proven treatment effect. The report says the study was observational, so differences in health, surgery type, complications, or other factors could help explain why some patients walked more and recovered differently.
Walking Patterns and Recovery Outcomes
The findings add patient-level step-count data to the rationale for helping people move when it is medically safe after surgery. Early mobility is already used in medical centers as part of recovery care; the source report says it may help reduce risks such as lung complications, blood clots, weakness, and longer hospital stays.
For patients and care teams, tracking activity may offer one practical way to follow recovery and spot when someone could need more support. But the study does not establish a universal step target or show that every patient should increase activity at the same rate. The appropriate level depends on factors including the operation, overall health, and any complications.
The reported percentages should also be read as relative associations tied to each 1,000-step increase over the participant’s own presurgical average. They do not mean that every patient will see the same reduction in risk, and they do not provide an individual’s personal recovery forecast.

How the Study Measured Activity
The research compared patients’ daily postoperative steps with their average step count before surgery, rather than applying one fixed activity threshold to everyone. Participants had to wear step-counting devices for at least a week before their operations and for several weeks afterward, on average.
The source report describes participants as adults who had various forms of inpatient surgery. It does not identify particular procedures, provide a detailed breakdown of patient characteristics, or specify the exact average follow-up period beyond saying it lasted several weeks. Those details limit how specifically the results can be applied to an individual procedure or patient group.
The report also notes that the study’s findings are consistent with other studies linking more postoperative walking with fewer complications. It does not give the details of those studies, so the current report’s central evidence remains the association observed in this analysis.
“Ask your surgical team when it’s safe to start increasing your activity level.”

Limits of the Recovery Evidence
Because the research was observational, it cannot determine whether more steps led to fewer complications or whether patients who were already recovering well were more able to walk. The findings may also reflect differences in health status, operation type, or other factors not described in the source report.
The report does not provide a recommended daily step count, explain whether the association differed by type of surgery, or give the numerical reduction in hospital stay. It also does not establish that wearable trackers improve recovery; they may help patients and clinicians monitor activity, but that effect is not reported as a study finding.
Patients should not treat the 1,000-step figure as a prescription. The study measured steps relative to each person’s presurgical average, and the source advises asking the surgical team when it is safe to increase activity.

Follow-Up for Patients and Clinicians
The source report does not announce a follow-up study or a change to surgical-care guidance. For now, the practical next step it describes is for patients to ask their surgical team about safe activity levels during recovery. Clinicians can use activity tracking as one possible way to monitor progress and identify patients who may need additional support.
Further research would be needed to determine whether increasing steps directly reduces complications or readmissions, what activity targets are appropriate for different operations, and how much walking is safe for people with different recovery needs. Until those questions are answered, the findings are best understood as evidence that higher postoperative step counts were linked with better outcomes in the studied group.

Key Questions
How many steps should I take after surgery?
The study does not set a daily step target. Ask your surgical team when it is safe to increase activity and what level fits your operation and recovery.
Did the study prove that walking prevents complications?
No. It was an observational study, which found that more postoperative steps were associated with lower complication and readmission likelihood but cannot establish cause and effect.
What did the study find about readmissions?
For each additional 1,000 daily steps above a patient’s presurgical average, the study reported a 15% lower likelihood of readmission within 30 days. This is an association, not a guaranteed reduction for any individual.
Can a wearable tracker help during recovery?
The report says a wearable device can help track progress and may help a health care team identify whether a patient needs additional support. The study findings described do not prove that using a tracker improves outcomes.
