Digital health, technologies, rehabilitation

The digital transformation of medicine

The digital transformation of medicine is redefining how care is delivered, monitored, and managed. Technologies such as apps, sensors, artificial intelligence, and telemedicine platforms are increasingly entering daily clinical practice. However, this evolution raises questions about effectiveness, safety, and appropriateness. To provide clarity, the Digital Therapeutics Alliance proposed in 2023 a classification framework designed to distinguish support tools from true therapeutic interventions [1]. The strength of this guide lies in the fact that it does not focus solely on the product’s form – whether an app, a platform, or a device – but above all on its declared intended use, the type of end user, the associated risk level, the clinical evidence required, the type of intervention (monitoring, support, diagnosis, treatment), and the level of regulatory oversight needed. This classification helps bring order, avoid terminological misuse, and promote the conscious and safe adoption of digital technologies in clinical practice.

 

 

Digital Health, Digital Medicine, and Digital Therapeutics: what do they really mean?

Digital Health encompasses all digital technologies used to improve people’s health and well-being, from lifestyle apps to remote monitoring systems. Within this broad category lies Digital Medicine, a narrower and more clinically relevant subset. These are scientifically validated digital tools, designed to measure or intervene on people’s health and supported by clinical studies.
At the heart of this ecosystem are Digital Therapeutics (DTx): therapeutic software delivered digitally, with clear clinical objectives and supported by robust scientific evidence such as randomized controlled trials [2]. In DTx, the active ingredient is not a molecule, but a therapeutic algorithm, which must nonetheless demonstrate efficacy, safety, and clinical benefit just like a drug. DTx are distinct from simple Care Support solutions, which do not deliver active treatment but enable self-management of disease – especially chronic conditions – and therefore require lower levels of clinical evidence.

 

 

Why rehabilitation is ready for the digital leap

Among the different branches of medicine, rehabilitation is one of the most promising for digital innovation. Rehabilitation pathways require key elements such as continuity, repetition, personalization, measurement, and active patient engagement, all aspects that traditional models struggle to provide due to structural challenges: staff shortages, logistical barriers, poor adherence to home-based therapy, and limited capacity for objective progress measurement.
Digital technologies can address these critical points by offering concrete and effective solutions. Today, this is no longer just an opportunity but a real necessity to meet a global demand. According to the WHO, more than 2.4 billion people worldwide live with conditions that could benefit from rehabilitation [3]. Yet, in many countries, less than half are able to access these services. In Italy as well, demand is steadily growing, driven by an aging population and the increasing prevalence of chronic diseases.

 

Technologies serving rehabilitation

Digital rehabilitation provides a scalable, concrete response to the main shortcomings of traditional models, offering treatment continuity, greater personalization, and more objective assessments.
According to the Peterson Health Technology Institute (PHTI) [4], the main modes of digital rehabilitation delivery can be distinguished as follows:

  • Telerehabilitation (synchronous telemedicine): the therapist interacts with the patient in real time, providing instructions and assessing correct exercise execution. This model replicates the outpatient dynamic at a distance.
  • Digital Rehabilitation or Digital Therapeutics (asynchronous mode): certified software guides the patient, records progress, and shares data with the therapist, who reviews it later. The patient takes on an active and autonomous role.
  • Hybrid approaches: a combination of synchronous and asynchronous sessions, leveraging the advantages of both modes depending on the rehabilitation pathway.

Enabling technologies that support these modes include:

  • Virtual reality and serious games, making therapy more engaging and motivating;
  • Sensors and wearable devices, objectively monitoring movement and personalizing treatment;
  • Video tracking systems, capturing body movements without applied devices, with real-time feedback;
  • Robotic devices and exoskeletons, assisting and automating parts of rehabilitation;
  • Telemonitoring platforms, integrating data collection and sharing between patients and healthcare professionals.

These technologies do not replace clinicians but expand their capabilities, allowing them to better monitor, adapt, and document treatment and provide more continuous, personalized, and patient-centered care.

 

Artificial Intelligence and Rehabilitation: the future of tailored therapy

Artificial Intelligence (AI) plays a crucial role in the evolution of DTx for rehabilitation, going far beyond advanced automation. AI can support:

  • Predictive therapy: combining clinical and behavioral data, AI can forecast recovery trajectories and suggest proactive protocols.
  • Dynamic adaptation: machine learning algorithms analyze patient performance (movements, reaction times, accuracy of exercises) and adjust in real time the level of difficulty or type of activity.
  • Dropout prevention: AI can detect early signs of poor adherence (e.g., reduced frequency of use) and suggest personalized motivational strategies.
  • Objective assessment: data analysis from wearables, cameras, or interactive platforms enables precise measurement of motor or cognitive improvements, complementing or replacing subjective therapist evaluations.

AI does not replace clinical judgment but enhances it, amplifying the professional’s ability to provide effective, tailored care.

 

An evolving ecosystem

Globally, the term Digital Therapeutics first appeared in 2015, with the first FDA approval in 2017 [5], paving the way for a new generation of “digital prescriptions.” Countries such as Germany, with the DiGA Fast Track reimbursement program launched in 2020, have established public reimbursement systems for these therapies [6], followed by similar initiatives in France, the UK, Belgium, Spain, Japan, and South Korea.
In Italy, the topic began to take shape in 2019 with the “Digital Therapeutics, an Opportunity for Italy” project, promoted by Fondazione Smith Kline (FSK), which led to the publication of the first official document on the subject [7]. Interest in DTx has since grown across the scientific community, institutions, and industry. In 2023, a more structured phase began with the updated initiative Digital Therapeutics, a Necessity for Italy, the result of collaboration between FSK and FADOI, aiming to respond to the sector’s evolution more systematically [8]. That same year, the first of three draft laws (DDL no. 1208, XVII Legislature) was submitted to the Italian Parliament, containing specific provisions on digital therapeutics, including those for rehabilitation [9].

Further confirmation of this growing interest came in 2025 from the Life Science Innovation Observatory of the Politecnico di Milano, which provided a detailed picture of both the Italian and international landscape. The data showed that 65% of patients are willing to use a DTx, especially if recommended by their physician, and more than half of healthcare professionals, including general practitioners and specialists, would be in favor of prescribing one, provided patients have the necessary digital skills [10].

Despite this rising interest, significant barriers remain to the widespread adoption of DTx in Italy. Chief among them: the absence of a national reimbursement system under the Italian National Health Service (SSN) and the challenges for companies to demonstrate clinical and economic benefits in a structured way. Many companies are nevertheless investing in this direction: one in three has plans to develop or commercialize DTx solutions, though fewer have begun clinical trials, and many are constrained by development costs and the lack of reimbursement mechanisms.

In this context, the idea is gaining traction that, for DTx to become truly sustainable in Italy, a B2G model similar to that of traditional drugs must be adopted, where access is granted via medical prescription and public or insurance reimbursement. This approach would ensure equity of access, incentivize rigorous clinical validation, and allow integration of DTx into care pathways. At the same time, hybrid models are also being tested, such as reimbursement conditional on clinical outcomes, licenses purchased by local health authorities or hospitals, and pay-per-performance formulas [11].

For DTx to become an integral part of the healthcare system, however, several fundamental steps are needed: establishing an updated regulatory framework, allocating public funds to research and scientific validation, launching training and awareness programs for physicians and patients, and seriously addressing ethical issues related to sensitive data use and AI.

In the rehabilitation sector, digital therapeutics designed to support personalized, continuous, home-based pathways are of particular interest. In Italy, also thanks to investments from the National Recovery and Resilience Plan (PNRR), a favorable regulatory context for telerehabilitation has been created. Since 2022, several ministerial decrees and guidelines have detailed the requirements for teleconsultation, telemonitoring, and remote rehabilitation treatments, including organizational, legal, and safety aspects [12]. A key milestone was the 2025 launch of the National Telemedicine Platform, expected to reach up to 800,000 patients by 2026, ensuring interoperability with the new Electronic Health Record (FSE 2.0) and compliance with European security standards.

The Italian context is now mature, at least from a regulatory and infrastructural standpoint, to welcome DTx as an integral part of the healthcare system. Operational challenges remain: fostering digital culture, training healthcare professionals, supporting research, and structuring evaluation and reimbursement pathways. But the foundations are in place, and the future of rehabilitation, more personalized, accessible, and digital, has already begun.

 

Why digital health is the key to more effective and inclusive rehabilitation

Digital health represents a major opportunity, but also a regulatory and cultural challenge. Rehabilitation, in particular, is fertile ground for technologies that can improve access, effectiveness, and equity of treatment. Artificial intelligence and digital therapeutics are no longer futuristic scenarios but realities in the making. To fully harness their benefits, we need training, clear rules, targeted investments, and above all, a patient-centered vision.
