Problem Statement
Problem Statement
Home rehabilitation is an important step for patients with upper limb injury; but repetitive tasks, slow improvements, and limited provider guidance reduce their motivations and hinders recovery.
Home rehabilitation is an important step for patients with upper limb injury; but repetitive tasks, slow improvements, and limited provider guidance reduce their motivations and hinders recovery.
Solution
Reeha is a platform that makes home rehabilitation practices motivating and less mundane by integrating rehabilitations into gamified activities with interactive visual and audio feedback.

Who is our primary and secondary target users?
Our team mapped stakeholders to define scope and target users, focusing on adults aged 25 to 60 recovering from upper-limb injuries at home or had past experience. The map also helped us identify essential clinical perspectives from occupational therapists, physical therapists, and physicians to guide product decisions and ensure clinical relevance.

Understanding patient pain points and needs
Understanding patient pain points and needs
Through 8 user interviews and 4 expert interviews, we identified monotony, confusion, and disconnection from clinical guidance as key barriers to sustained home rehabilitation. Patients don’t just want to perform exercises correctly, they want to feel supported, understood, and able to see their progress over time.

“A study showed that a year after discharge, only about 20% of physical therapy patients stuck with their home exercises...Patients are performing exercises incorrectly all the time.”

Data Analysis of User Pain Points
We found high correlation between user and expert interviews around core challenges (Design & Tech Gaps, Psychological, and Emotional Barriers) that impact patient emotional journey. We learned that motivation depends on visible progress and timely feedback.

The patient follows exercise guides on the screen while the TrueDepth camera tracks their movements.
Digital Section
Their movement data controls mini-games that give instant feedback. After each game, progress is sent to the doctor, who chooses the next games.

Mini Game Example: Muscular Cupcake
In our interviews, rehabilitation users expressed a stronger desire to return to everyday activities rather than perform isolated clinical exercises. This created an opportunity to design rehabilitation experiences rooted in familiar daily activities, using themed mini-games (e.g., baking, playing sports, gardening, etc) to translate therapeutic movements into real-world goals.

Training First, Play When Ready
We found that beginners and experienced users preference in practicing. We moved game selection to a secondary layer and gave users two clear options: exercise only or exercise with game.
This iteration better supports users at different stages of familiarity and helps training feel more intentional and flexible.

Balancing Professionalism and Connection.
Balancing Professionalism and Connection.
User feedback showed that too much emphasis on games made the product feel less professional and raised concerns about clinical credibility.
We restructured the information architecture by lightening the presence of games, while bringing Clinic and Message to the primary navigation. This allowed users to focus on progress, appointments, and communication first.

Real-Time Instruction for Perfecting Form.
Real-Time Instruction for Perfecting Form.
Multiple users said they want to know how to fix their movement while they were still performing it.
We redesigned the interaction to shift from passive feedback to active guidance.
This change better supports learning, reduces frustration, and aligns with our rehab goal of helping users practice safely and confidently at home.
