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?

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

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.
