Recovering from surgery is not always easy. Some patients bounce back quickly, while others struggle with pain, weakness, infections, or unexpected complications.
Doctors usually monitor recovery by checking blood pressure, heart rate, pain levels, and asking patients how they feel. But a new study suggests there may be a much simpler and more accurate way to track recovery: counting steps.
Researchers studying data from the National Institutes of Health’s All of Us Research Program discovered that patients who walked more after surgery generally recovered better. Higher daily step counts were linked to shorter hospital stays, fewer complications, and lower chances of returning to the hospital.
The findings were published in the Journal of the American College of Surgeons and are raising interest in how wearable technology could change patient care in the future.
The study followed 1,965 adults who underwent surgery requiring hospital admission. These patients used wearable devices such as fitness trackers or smartwatches that continuously recorded physical activity.
Scientists combined the wearable information with electronic health records to study how movement after surgery affected recovery outcomes.
The results showed a strong pattern. Every additional 1,000 steps a patient walked each day after surgery was linked to better health outcomes. Patients who walked more recovered faster and experienced fewer problems.
Researchers found that each extra 1,000 daily steps was associated with a 6 percent shorter hospital stay. Patients with higher step counts were also less likely to experience complications within 30 or 90 days after surgery.
Hospital readmissions were lower as well. Patients who remained active after surgery had a smaller chance of needing to return to the hospital after discharge.
The researchers adjusted for many other factors that could influence recovery, including age, sex, and the overall risk level of the surgery. Even after accounting for those differences, step count remained one of the strongest predictors of recovery success.
Interestingly, the study found that other common recovery measures were much less useful. Researchers examined heart rate variability, which reflects changes in the timing between heartbeats and is often linked to physical stress and recovery.
Patients also completed wellness questionnaires describing how they felt physically and emotionally. However, neither heart rate variability nor self-reported wellness scores predicted recovery outcomes as strongly as daily walking activity.
This finding suggests that step count may provide doctors with a very practical and objective way to monitor recovery progress.
Dr. Timothy Pawlik, senior author of the study and professor at The Ohio State University Wexner Medical Center, explained that wearable devices can give doctors real-time information about how patients are doing after surgery.
According to Dr. Pawlik, doctors often rely on patient descriptions such as “I feel okay” or “I’m still tired.” But wearable devices provide measurable information that may reveal recovery problems earlier.
For example, if a patient’s activity level suddenly drops, healthcare providers may recognize a problem before more serious complications develop. Doctors could then arrange extra support such as physical therapy, additional checkups, or closer monitoring.
Walking itself may also help the body heal. Movement improves circulation, supports lung function, prevents muscle loss, and reduces the risk of blood clots. Patients who stay active after surgery may therefore recover more efficiently.
The study also connects with earlier research presented at the American College of Surgeons Clinical Congress in 2023. That research found that people who walked more than 7,500 steps per day before surgery had a much lower risk of complications afterward.
Together, these studies suggest that physical activity before and after surgery may both play major roles in successful recovery.
Wearable devices are becoming more common every year. Millions of people already use smartwatches and fitness trackers to monitor exercise and health. Researchers believe these devices may soon become routine tools in hospitals and surgical recovery programs.
In the future, doctors may use wearable data to create personalized recovery goals for patients. For example, a patient could be encouraged to reach a certain step target before surgery and gradually increase activity afterward.
At the same time, experts emphasize that recovery plans should always be individualized. Some patients may have serious health conditions that limit movement. Walking goals should always be discussed with healthcare providers to make sure they are safe.
The study has several important strengths. It included a large number of patients and used objective information collected continuously by wearable devices rather than relying only on questionnaires.
However, the researchers also acknowledged limitations. The study cannot fully prove that walking directly causes better recovery outcomes. Patients who naturally recover faster may simply feel well enough to move more. Future research may help answer this question more clearly.
Even so, the connection between step count and recovery was so consistent that researchers believe physical activity likely plays an important role in healing.
After analyzing the findings, the study appears highly valuable because it combines modern wearable technology with real-world medical care. The results strongly support the idea that simple movement after surgery may significantly influence recovery.
While more research is needed to prove direct cause and effect, the evidence suggests wearable devices could become an important tool for improving patient care and helping doctors identify recovery problems earlier.
