TL;DR
HEP compliance refers to how consistently patients follow through on home exercise programs prescribed by their therapist. Research shows only 35% to 50% of patients comply, with some studies putting full adherence as low as 21%. The main barriers are forgetfulness, pain, program complexity, and low self-efficacy. Evidence-based strategies like video-based delivery, behavioral nudges, simplified programs, and Remote Therapeutic Monitoring (RTM) can significantly improve outcomes.
What Is HEP Compliance?
A HEP, or Home Exercise Program, is a set of exercises and activities a rehab clinician prescribes for a patient to perform between clinic visits. HEP compliance is the degree to which that patient actually follows through on the program as prescribed.
The concept sounds simple. A physical therapist demonstrates three exercises, explains the sets and reps, and sends the patient home with instructions. But what happens between visits is where most treatment plans fall apart. HEP compliance captures this gap between what’s prescribed and what’s performed.
Clinicians across physical therapy, occupational therapy, chiropractic care, and speech-language pathology all deal with this problem daily. The term shows up in clinical documentation, outcome tracking, insurance justifications, and increasingly in RTM billing workflows.
One important note: “compliance” and “adherence” appear interchangeably in most rehab settings, but they carry different connotations worth understanding.
HEP Compliance vs. Adherence vs. Concordance
The rehab field is gradually moving away from “compliance” toward “adherence,” though most clinicians still use both terms. Here’s why the distinction matters.
| Term | Implication | Patient Role | Provider Role |
|---|---|---|---|
| Compliance | Passive obedience | Follows orders | Gives orders |
| Adherence | Active participation | Chooses to follow through | Provides guidance |
| Concordance | Shared decision-making | Co-creates the plan | Collaborates as partner |
According to the HCA Healthcare Journal, adherence is “an active choice of patients to follow through with the prescribed treatment while taking responsibility for their own well-being,” while compliance is “a passive behavior in which a patient is following a list of instructions from the doctor.”
Modern clinical literature prefers the term “adherence” because it acknowledges the patient’s agency. Compliance implies a top-down dynamic that doesn’t reflect how effective rehab actually works.
That said, clinicians still search for “hep compliance” because it’s the phrase embedded in years of clinical education and conversation. Both terms describe the same real-world challenge: patients not doing their exercises at home. This article uses both.
HEP Compliance Rates: How Bad Is the Problem?
The numbers are consistently discouraging across decades of research.
Patient adherence to home exercise programs sits at roughly 35% to 50% in most studies. A systematic review spanning two decades found that only 21% of patients were fully adherent to their HEPs. For musculoskeletal conditions specifically, non-adherence can reach 65% to 70%.
One study on back pain illustrated the gap perfectly: 51% of patients had high compliance with attending physical therapy sessions, but only 35% had high compliance with their home exercise program. Patients show up to the clinic. They just don’t follow through at home.
A stat that helps explain why: patients forget 40% to 80% of medical information and recommendations immediately after leaving a clinical encounter. If someone can’t remember the instructions, they certainly can’t comply with them.
These numbers make it clear that poor HEP compliance isn’t a fringe problem. It’s the default state of rehab care.
Common Barriers to HEP Compliance
Understanding why patients don’t follow through is the first step toward fixing the problem. The barriers break down into two categories.
Patient-Side Barriers
Forgetfulness is the single most cited reason patients skip their exercises. Given that up to 80% of clinical information is forgotten immediately, this shouldn’t surprise anyone. A printed sheet buried in a bag or stuck on a fridge rarely survives the week.
Pain during exercises discourages continuation. When a patient experiences discomfort while performing their HEP, they often conclude (sometimes correctly, sometimes not) that the exercise is harmful and stop.
Time constraints rank consistently high. Patients juggling work, family, and other appointments struggle to carve out dedicated exercise time, especially when programs feel long.
Low self-efficacy is a barrier clinicians can directly influence but often don’t. A survey of 454 physical therapists found that 58% rated self-efficacy as “very” to “extremely” important for patient adherence. Yet many PTs who didn’t assess self-efficacy reported not knowing how, or what to do with the information once collected.
Program complexity has a measurable effect. Research shows that patients adhere best to 2 or fewer prescribed exercises rather than lists of 4 or 8. Prescribing fewer exercises leads to better performance, frequency, and self-reported compliance.
Psychological factors like anxiety, depression, and external locus of control also suppress adherence. Patients who believe their recovery depends entirely on the clinician (rather than their own effort) are less likely to do the work at home.
For a deeper look at how patient literacy affects comprehension of exercise instructions, that’s a related and often overlooked factor.
Provider-Side Barriers
Vague or overly complex instructions set patients up to fail. When a clinician demonstrates seven exercises in the last three minutes of a session and hands over a black-and-white printout, compliance is almost guaranteed to be poor.
Lack of follow-up between visits means patients go days or weeks without accountability. No check-in, no reminder, no course correction.
Failure to personalize the program to the patient’s daily life, goals, and capabilities creates a disconnect. Generic library exercises that don’t match the clinician’s specific cues or the patient’s actual environment feel impersonal.
No visual reinforcement after the visit. Paper handouts with stick-figure diagrams are the standard in many clinics, and they’re dramatically less effective than video-based alternatives (more on this below).
Practitioners on Reddit frequently discuss how patients lose or ignore printed HEPs within days, reinforcing what the research already shows: the delivery format matters as much as the content. Addressing these provider-side barriers is central to writing clear exercise prescriptions that patients can actually follow.
Why HEP Compliance Matters: Clinical and Business Impact
Clinical Impact
Patients who comply with their HEP achieve rehab goals faster, experience pain relief sooner, and have fewer recurrences. This isn’t speculative. Adherence to a home exercise program is associated with superior functional outcomes compared to non-adherence.
The inverse is equally true. Non-compliant patients plateau, require more visits to reach the same milestones, and are more likely to drop out of care prematurely, often concluding that “therapy didn’t work.”
Business Impact
For clinic owners, poor HEP compliance creates a cascade of operational problems. Slower outcomes mean more visits per episode of care, which strains clinician bandwidth. Patient satisfaction scores drop when people don’t see progress. Dropout rates climb, and those patients aren’t referring friends.
HEP compliance directly connects to the KPIs that drive clinic growth: NPS scores, retention rates, referral volume, and per-patient revenue. A clinic that solves the compliance problem doesn’t just deliver better care; it becomes more efficient and more profitable. For more on this connection, see how improving patient experience drives revenue.
Non-compliance also correlates with no-shows. A patient who isn’t doing their exercises often feels guilty or unmotivated to attend the next session. Clinics battling high no-show rates should consider that reducing patient no-shows and improving HEP compliance are two sides of the same coin.
Evidence-Based Strategies to Improve HEP Compliance
Simplify the Program
The evidence is clear: fewer exercises mean better compliance. When patients receive 2 to 3 targeted exercises instead of 6 to 8, they perform them more frequently and with better form. Resist the urge to prescribe comprehensively. Prescribe what the patient will actually do.
Use Video Instead of Paper
A 2020 randomized controlled trial found that patients given a mobile video-guided home exercise program achieved 75.6% adherence versus 55.2% for those given paper handouts. That’s a 20-percentage-point improvement from changing the delivery format alone.
Separately, when asked their preference, 69% of patients chose video over paper handouts. Video lets patients see exactly what the clinician demonstrated, with the right form, tempo, and cues. It eliminates the guesswork that paper introduces.
Custom video, where the clinician records the patient performing the exercise during the visit, is even more powerful than stock library video. The patient sees themselves, hears their therapist’s voice, and connects the exercise to their specific session.
See AC Health pricing for a platform that supports one-tap custom video creation during visits.
Deploy Behavioral Nudges and Reminders
Behavioral science offers practical tools for HEP compliance. Research in BMC Nursing found that patients most preferred three nudge strategies: pre-commitment (34.6%), alerts and reminders (21.8%), and social norms (18.1%).
Pre-commitment means asking patients to commit to a specific time and place for their exercises before leaving the clinic. Alerts and reminders are straightforward: automated push notifications or messages that prompt action. Social norms involve showing patients that most people in their situation complete their exercises, creating gentle peer pressure.
Compliance with behavioral treatments like exercise programs mirrors drug compliance: as complexity increases, compliance decreases. Nudges counteract this by reducing the cognitive burden of remembering and deciding.
For practical guidance on setting these up, see how to schedule habit-forming reminders for patients.
Assess Self-Efficacy Before Prescribing
If a patient doesn’t believe they can perform the exercises correctly or that the exercises will help, compliance will be low regardless of everything else. The research shows that most PTs recognize self-efficacy as critical but lack a systematic approach to measuring and addressing it.
Simple screening questions work. “On a scale of 1 to 10, how confident are you that you can do these exercises at home?” A low score is a signal to simplify, demonstrate more, or address the patient’s specific doubts before they leave.
Use Motivational Interviewing Techniques
Rather than telling patients what to do, ask questions that help them articulate their own reasons for following through. “What would it mean for you to be able to pick up your grandchild without pain?” This approach taps into intrinsic motivation, which is far more durable than clinician-directed compliance.
Maintain Contact Between Visits
A patient who hears nothing from their clinic for two weeks has every opportunity to fall off track. HIPAA-compliant in-app messaging, check-ins, and progress acknowledgments keep the therapeutic relationship active between sessions.

The Role of Technology in HEP Compliance
Technology doesn’t replace the clinician-patient relationship, but it solves several of the structural problems that undermine HEP compliance.
Digital HEP Platforms
Digital platforms replace paper handouts with video-based exercise libraries (or custom recordings), delivered directly to the patient’s phone. The patient can review their program anytime, replay demonstrations, and access updated instructions without calling the clinic.
The shift from paper to digital HEP delivery addresses the forgetting problem head-on. Instead of relying on memory, patients have a persistent, visual reference in their pocket. Platforms that allow clinicians to create custom exercise videos quickly during the visit add another layer of personalization.
Automated Reminders and Behavioral Triggers
In-app behavior triggers and personalized reminders prompt patients to complete their exercises at the times they’ve committed to. This addresses the forgetfulness barrier directly, without requiring clinician effort for every nudge.
Remote Therapeutic Monitoring (RTM)
RTM transforms HEP compliance tracking from a subjective guess into objective, reimbursable data collection. The AMA clarifies that RTM data may relate to “signs, symptoms, compliance, and functions of a therapeutic response.”
The relevant CPT codes include:
- 98975: Initial setup and patient education on the RTM device/software (billed once per episode)
- 98977: Supply of the RTM device; billable every 30 days with at least 16 days of data
- 98980: Treatment management services, first 20 minutes
- 98981: Each additional 20 minutes of treatment management
RTM turns HEP compliance monitoring into a revenue stream while improving care. Clinics can track completion rates in real time, intervene when patients fall off, and document adherence for payer requirements.

How to Measure HEP Compliance
Traditional Methods
Verbal self-report has been the standard for decades. The therapist asks, “Have you been doing your exercises?” and the patient says yes (whether or not it’s true). Exercise logs offer slightly more structure but still rely entirely on honest self-reporting.
The problem: self-reported adherence consistently overestimates actual compliance. Patients want to please their provider, and memory is unreliable.
Modern Methods
Digital platforms track exercise completion automatically. When a patient opens a video, marks an exercise complete, or logs activity through an app, the data flows into the clinician’s dashboard without anyone needing to ask.
RTM data collection provides the most robust measurement. With at least 16 days of tracked data per 30-day billing cycle, clinics get a longitudinal view of patient behavior that verbal check-ins can’t match.
For guidance on documenting this data, see how to document patient home exercise compliance.
Objective measurement changes the conversation. Instead of “Are you doing your exercises?” a clinician can say, “I see you completed your program 4 out of the last 7 days. Let’s talk about what’s getting in the way on the other days.” That specificity builds trust and enables targeted problem-solving.

Frequently Asked Questions
What is a good HEP compliance rate?
Most research defines “good” as above 80% adherence to the prescribed frequency and exercises. In practice, achieving even 50% compliance is above average, given that baseline rates sit between 35% and 50%. Clinics using video-based delivery and automated reminders routinely see rates above 70%.
What is the difference between compliance and adherence in physical therapy?
Compliance implies passive obedience to a provider’s instructions. Adherence implies the patient actively chooses to follow through, taking responsibility for their own care. The clinical community increasingly prefers “adherence” because it reflects a collaborative relationship. Both terms describe the same practical challenge.
How do you track HEP compliance?
Traditional tracking relies on patient self-report, which tends to overestimate actual compliance. Modern digital platforms track exercise completion automatically through in-app activity data. Remote Therapeutic Monitoring (RTM) provides the most objective tracking, with CPT codes 98975 and 98977 covering setup and device supply for compliance monitoring.
Does video improve HEP compliance?
Yes. A randomized controlled trial found 75.6% adherence for video-based HEPs compared to 55.2% for paper handouts. Custom video, where patients see their own clinician demonstrating during their visit, appears to be even more effective than generic library content.
What CPT codes cover HEP compliance monitoring?
RTM codes 98975 (initial setup), 98977 (device supply, billed monthly), 98980 (treatment management, first 20 minutes), and 98981 (each additional 20 minutes) all apply to HEP compliance monitoring when using a qualifying digital platform.
How many exercises should a HEP include?
Research suggests that 2 to 3 exercises produce better compliance than programs with 4 or more. Patients who receive shorter, focused programs perform exercises more frequently and with higher self-reported adherence.
Why do patients stop doing their home exercises?
The most common reasons are forgetfulness, pain during exercises, time constraints, low confidence in their ability to perform correctly, and programs that feel too complex or irrelevant to their daily life. Patients also forget 40% to 80% of clinical instructions immediately after their visit, making retention of exercise details a fundamental challenge.
Can behavioral nudges improve HEP adherence?
Yes. Studies show patients respond well to pre-commitment strategies (agreeing to a specific exercise time), automated reminders, and social norm messaging. These nudges reduce the cognitive effort required to remember and decide to exercise, which is especially valuable for patients with busy schedules or low intrinsic motivation.
