Rehabilitation trials measure what people can do: walk, balance, climb stairs, get back to work. Capture records therapist-run performance tests, functional scales and home exercise adherence in one study, with blinded assessors and no setup fee for academic budgets.

What matters in rehabilitation trials
Outcomes
Rehabilitation research asks whether an intervention helps people function: walk further, fall less, return to daily activities. That means outcomes such as the six-minute walk test, timed up and go, balance scales, grip strength and activities of daily living scales, plus participant-reported function. Each has a standard administration protocol, and variations in how a test is done (the length of the corridor, the encouragement given, the walking aid used) change the result.
In Capture, performance tests are built as site forms completed by the assessor, a performance outcome in eCOA terms. Each measured value is a number field with its unit and a plausibility range, and the context that affects interpretation (walking aid, rests, oxygen use) is recorded alongside the result rather than in a comment box.
Therapists delivering an exercise or device intervention cannot be blinded, so outcome assessment is usually done by a separate assessor who does not know the allocation. Assign assessors a role without access to treatment allocation, and use the field-level audit trail to confirm that outcome forms were completed by assessors rather than treating therapists.
Performance tests show capacity in the clinic; participant-reported measures show function in daily life. PROMIS short forms from the Capture library, or condition-specific questionnaires, can run on participants' phones between visits.

Home programs
A home exercise program only works if it is done. A short daily or weekly diary on the participant's phone records sessions completed, duration and difficulty, with reminders and a completion window. Adherence data then sits next to outcomes, so you can analyse dose as well as allocation.

Academic budgets
Many rehabilitation trials are run by clinical academics with therapists as site staff. Capture has no setup fee and no per-site fee; you build and test the full study free and pay only when it goes live. The AI Study Generator drafts the schedule and forms from your protocol, so the build does not wait for a programmer.

Try both in the free sandbox and complete the diary on your phone.
Common measures
| Measure | Type | Capture as |
|---|---|---|
| Six-minute walk test | Performance | Site form: distance, rests, aid, exertion, oxygen saturation |
| Timed up and go | Performance | Site form: time in seconds, aid used |
| Balance scales | Clinician-rated | Site form: one field per item, total derived in analysis |
| Grip strength | Performance | Site form: repeated trials as table rows |
| Activities of daily living scales | Clinician or participant | Site form or ePRO depending on the instrument |
| PROMIS Physical Function | Participant-reported | ePRO from the library, licence tracked |
| Exercise adherence | Participant-reported | Recurring ePRO diary |

Intervention fidelity
In drug trials the intervention is a tablet with a known dose. In rehabilitation trials it is a series of sessions delivered by different therapists, adapted to each participant's progress. Whether the intervention was delivered as intended (its fidelity) is part of the result, and reviewers increasingly expect it to be measured.
A short session log completed by the treating therapist after each session records what was delivered: duration, components, intensity and any reason a session was modified or missed. Combined with the participant's home exercise diary, it shows the dose actually received in both supervised and unsupervised parts of the programme. Because therapists are site staff, the log is a site form, attributed to the therapist in the audit trail, separate from the outcome forms completed by blinded assessors.
Rehabilitation trials often run across many hospitals and community services, where research is not anyone's full-time job. Short forms, clear visit windows and no per-site fees make it practical to include smaller services. See pragmatic clinical trials for design considerations.
Study build

Short recurring diary with reminders.
For any licensed functional scales and PROMIS forms.
Walking aids, rests and oxygen use recorded with results.
Performance tests such as the six-minute walk and timed up and go, clinician-rated function and balance scales, and participant-reported function and quality of life.
As site forms completed by the assessor, with numeric results, units, plausibility ranges and the context that affects interpretation.
Assign assessors a role without access to treatment allocation, and use the audit trail to confirm who completed each outcome form.
Yes. A recurring diary in the phone browser records sessions, with reminders and adherence shown on the dashboard.
There is no setup or per-site fee, and the full study can be built and tested free before going live.
Yes. PROMIS Physical Function 8b, Fatigue 8a and Cognitive Function 8a are in the library with licence tracking.
