Free physical therapy toolkits for clinicians and patients — built in the browser, no accounts
Jen (Jennifer Thai, PT, DPT, OCS) is a board-certified orthopedic physical therapist with over a decade of clinical experience across outpatient rehab and telehealth — treating weekend warriors and professional esports athletes alike. She holds a Doctor of Physical Therapy degree from USC and is based out of Los Angeles, CA, with practice offered via in-person, mobile, and telehealth visits.
Clinical focus: musculoskeletal injury, post-operative and total-joint rehab, pre-surgical conditioning, balance and fall prevention, manual therapy, and strength & conditioning programming. The animating principle: meet each patient where they are, then build evidence-informed treatment around their goals and lifestyle.
jen.PT is the public-facing companion to that clinical work — a solo-practice toolkit first. Built piece by piece by one person as needs surfaced in clinic, with Claude as collaborator, and shared here because it might be useful to others too.
Good care starts with good measurement. Evidence-informed practice — validated outcome measures, current research, and clinical reasoning rather than generic protocols — depends on having the right resources at hand: it keeps documentation consistent across visits, makes progress visible, and helps clinicians and patients make better decisions together.
In a hybrid practice — in-person visits and telehealth — the same gap kept surfacing: many of the outcome measures, decision aids, and reference materials used every day are either hard to find online or stuck in formats that create friction for use. PDFs you can't score on a tablet, worksheets that don't add up the numbers for you, manual interpretation of unique tools. Virtual care makes those gaps impossible to ignore.
These tools were built to bridge that gap. The collection now spans ~30 interactive outcome measures, a photo-based 3-point goniometer for joint range of motion, evidence-anchored timelines for conservative management of common musculoskeletal conditions, prehabilitation pathways for elective surgery, phase-by-phase post-surgical recovery roadmaps, interactive clinical prediction rules with live likelihood ratios, and APTA / JOSPT guideline summaries — plus a metronome and stopwatch for paced exercise and tempo work.
The goal of every tool is a lightweight, content-rich page that works the same on computer and mobile displays. Each comes with a plain-language summary and citations, credited to the original instrument's authors and rights holders. Everything runs entirely in your browser: nothing is uploaded, no patient data ever leaves the device, and no accounts.
These are clinical resource tools, not a replacement for clinical judgment or the official source materials. The collection grows as new clinical needs arise.
