1.7 Billion People Need Musculoskeletal Care. Is Your Clinic Ready to Serve Them?
The Silver Tsunami is no longer a metaphor. It is your regular Thursday schedule at the clinic. The oldest Baby Boomers are 79. The youngest are 61. The cohort most statistically likely to walk through your door, chronic lower back pain, post-surgical knee, and age-related balance decline, is at its largest point in history. And the care model most outpatient PT clinics are still running was not designed for them. Closing that gap is exactly what remote therapeutic monitoring was built to do.
The numbers confirm what clinic owners are already feeling. According to the World Health Organization, approximately 1.71 billion people globally are living with musculoskeletal (MSK) conditions, making MSK disorders the leading contributor to disability worldwide. A 2023 study in The Lancet Rheumatology, drawing on Global Burden of Disease 2021 data, projects that chronic lower back pain alone will affect 843 million people by 2050, a 36.4% increase from 2020. According to Grand View Research, the US PT market is on track to reach $76.61 billion by 2033, growing at 4.88% annually.
That growth is not coming from young athletes. It is coming from aging adults with complex, recurring MSK needs. The clinics that capture it will not be the ones with the best manual therapy skills alone. They will be the ones who figure out how to maintain a clinical relationship with these patients well beyond discharge.
Why the Episode of Care Model Fails Aging MSK Patients
As Definitive Healthcare defines it, an episode of care covers all services provided to treat a clinical condition within a specific time window, initiated with a referral and ending at discharge. The model was designed around discrete, contained events. A patient presents. You treat them. They hit their goals. They leave.
That works cleanly for a 27-year-old recovering from an ACL repair. It does not work for a 67-year-old with chronic lower back pain, a history of re-presentation, and a home exercise adherence rate that drops the moment clinical accountability ends.
Older adults with MSK conditions do not follow that arc. Recovery is slower. Setbacks are more frequent. The period of clinical vulnerability extends well past discharge. And the consequences of falling through the gaps (a fall, a re-injury, a sedentary spiral that erases months of progress) are far more serious than they are in younger populations.
Most PT clinic owners recognize the pattern without needing a study to confirm it: the same patients cycling back every few months with variations of the same complaint, each new episode treating the presentation rather than the trajectory. It is not a failure of clinical skill. It is a structural mismatch between the model and the population now filling your schedule.
What the Research Says About Monitoring MSK Patients Between Sessions
The clinical case for monitoring MSK patients between sessions has grown significantly, and the evidence points directly to the gap the episode-of-care model leaves open.
A 2025 narrative review in the Annals of Translational Medicine by Olawade et al. examined AI-driven virtual assistants in home rehabilitation, identifying remote monitoring as a key mechanism for improving patient adherence, detecting early functional decline, and enabling clinicians to intervene before a condition deteriorates. For older MSK patients in a PT setting, early detection is not a convenience. It is the difference between a quick clinical adjustment and a full new episode of care.
A January 2026 systematic review in JMIR mHealth and uHealth by Gu et al. examined wearable sensor technologies across real-world rehabilitation populations and concluded that continuous between-session data collection gives clinicians a level of insight into patient progress and decline that periodic in-clinic visits cannot produce on their own.
Both bodies of research point to the same conclusion: for aging MSK patients, the gap between appointments matters as much as what happens in the treatment room. The clinics that figure out how to be present during those hours will produce better outcomes and retain those patients longer.
PhyxUp Health Helps PT Clinics Close the Gap
Remote Therapeutic Monitoring (RTM) was built for exactly this clinical gap, and it comes with a billing structure that supports the business case without adding operational burden to your team. Through CPT codes 98975, 98977, 98979, 98980, and 98981, outpatient PT clinics can bill for the monitoring work that many therapists are already doing informally between sessions, without adding a single appointment to the schedule.

The care case and the revenue case are the same argument. The PT clinic that monitors a 68-year-old chronic back pain patient between sessions is simultaneously delivering better care and generating reimbursable revenue from that care. The patient who would have returned in three months with the same complaint stays engaged, stays adherent, and stays in your practice.
PhyxUp Health helps PT clinics navigate this demographic reality. Our fully managed RTM service handles:
- Patient onboarding
- Home program monitoring
- Between-session clinical review by licensed physical therapists
- Documentation and end-to-end billing
So your team stays focused on patient care, not paperwork.
The 1.71 billion people living with MSK conditions are not an abstraction. The aging subset of that population is already your patient panel. The clinics that build the infrastructure to serve them continuously, not just episodically, will define what outpatient MSK care looks like for the next decade.
