Apple Health Physical Therapy

A Practical Guide to Physical Therapy Tracking in Apple Health

Most people assume there is a built-in physical therapy module inside the Health app. There isn't. What exists is a fragmented collection of workout types, range of motion logs, and symptom trackers that can be forced into a coherent rehab workflow if you understand where the gaps are. I spent about fourteen months building a custom clinical dashboard around Apple Health data for a small orthopedic practice, and the process revealed a lot of things the documentation doesn't mention. The Health app stores data from several sources: the iPhone itself, the Apple Watch, third-party apps that write to HealthKit, and manual entries. For physical therapy specifically, the relevant data categories are Workouts, Range of Motion, Pain, Mindfulness, and various recovery metrics like heart rate variability. None of these are pre-assembled into a PT-specific view. You have to construct one. The first thing most people get wrong is assuming the Apple Watch handles rehab tracking automatically. It doesn't. The watch tracks active workouts like outdoor walks, cycles, and HIIT. It does not track passive stretching routines, isometric holds, or the kind of low-intensity mobility work that dominates a typical physical therapy program. You end up manually logging most of it, which means the quality of your data depends entirely on whether the patient actually opens the app after their session. In my experience, compliance drops below forty percent once manual logging is the only option.

The workaround that actually moved the needle was connecting the practice to a dedicated physical therapy app that writes back to HealthKit. Our clinic used Physitrack for exercise programming, and it pushes completed sessions into Apple Health as custom workout entries. Same thing with Fitbod and a few other rehab-focused apps. The catch is that the data fields map inconsistently. Physitrack sends "Strength Training" as the workout type, which buries the entry under generic gym sessions in the Health app. You can filter it out by checking the workout notes, but it requires a second step that most patients skip entirely. Range of Motion data is another minefield. The Health app accepts goniometer readings from apps like Range of Motion Pro or even simple manual entry. The problem is that there is no standardized unit field. One app records in degrees, another in radians, and the Health app does not validate the input. I had a patient who entered hip flexion values as 1.2 radians thinking the app wanted decimal degrees. The resulting graph looked like a flatline because the values were way too small. There is no warning system. No validation popup. Just bad data sitting in your dashboard. For pain tracking, the built-in symptom log is adequate but incomplete. It lets you log intensity from one to five, but it doesn't associate pain with specific movements or exercises the way a clinical tool should. I solved this by having patients use a separate entry app called Bearable alongside Apple Health, then exporting the CSV monthly. The export format includes date, time, pain level, activity context, and body region. You can then cross-reference it against workout logs imported from the same CSV. This usually takes about twelve minutes per month per patient once the workflow is established.

Setting up a basic physical therapy tracking routine

Start by opening the Health app and navigating to Browse > Shoulder or Knee (depending on the joint being treated) > Range of Motion. Tap Add Data and enter values from your clinician's baseline assessment. Do this before the first treatment session so you have a reference point. Most patients skip this and try to reconstruct ranges from memory later, which introduces error. Next, pair your Apple Watch and enable background workout detection. Go to Settings > Workout on the watch and turn on Detect Workout Ending. This reduces the chance of the watch leaving a session unrecorded when you finish stretching on the living room floor without explicitly stopping the workout. I learned this the hard way when a patient's week-long log showed zero data because every session ended mid-workout due to battery drain. The fix was simply enabling the auto-end feature and switching the watch to Low Power Mode during rehab sessions, which extended battery life enough to cover the full duration. For exercise compliance, the most reliable method is pairing a third-party app rather than relying on manual Health entries. If your clinic uses a specific platform, check whether it supports HealthKit export. Physitrack, Halo Health, and Vytalize all write to HealthKit. The data structure they use includes exercise name, sets, reps, and perceived exertion, but the perceived exertion field maps poorly. It often comes through as a generic number without context, making it difficult to distinguish between a patient who rated a set as a six versus a seven without additional notes.

Manual entry in the Health app remains the fallback for everything else. The process is straightforward but tedious. Open Health > Browse > Activity > Stand Hours or any of the other tracked categories, tap Add Data, and fill in the fields. It takes roughly forty-five seconds per entry. For a patient doing three exercises daily with pain and mobility logs, that is about four minutes per day. Over a month, that is two hours of logging. Most patients abandon manual entry within three weeks.

Things the documentation won't tell you

Apple Health does not support custom categories natively. If you want a physical therapy dashboard, you are building it yourself using the existing data categories and visualizing them through the Summary tab or a third-party tool like the Fitness+ integration or a custom Health app. There is no native way to create a rehab-specific view that consolidates ROM, pain, and exercise completion into a single timeline. Data privacy is another area where expectations diverge from reality. Health data is encrypted on device, but any third-party app that reads from or writes to HealthKit has its own privacy policy. If you use a clinic-managed app, that app's developer can see your health data unless they explicitly state otherwise. I recommend reviewing the app's HealthKit permission scope before linking it. Some apps request access to all health data when they only need workout and movement data. It is easy to miss. The biggest practical limitation is that Apple Health does not handle clinical-grade data well. The precision standards for ROM measurement, for example, require calibration and consistency that consumer apps rarely maintain. Two different apps measuring the same knee flexion can differ by eight to twelve degrees on the same limb. This matters when you are tracking progress over weeks. A change of five degrees could be real improvement or just measurement noise between two apps.

If you are a clinician relying on Apple Health data for treatment decisions, I would recommend using it as a supplementary tool rather than a primary record. For clinical tracking, a dedicated EHR-integrated platform like PT Sphere or TherapyNotes gives you structured data entry, clinical alerts, and billing compatibility that Apple Health cannot provide. Apple Health works well for patient engagement and general activity awareness. It is not designed for medical record-keeping. The bottom line is that Apple Health Physical Therapy is whatever you make it. The infrastructure is there, but it requires deliberate setup, consistent manual effort, and an awareness of where the data is likely to be inaccurate. Plan for the gaps before you rely on the numbers.
