Monitoring System for ACL Injury Recovery

Senior Studio –Collaboration with Tactile

Medical Monitoring Devices



Data Collection Through Movement 

The system provides clarity on the recovery progress to ensure a quick recovery, eliminate extraneous injuries, and provide direct feedback on range of motion progression for the patient and the physical therapist.

How it works...

An RGB video camera also records the patient's exercises when prompted and is the charging source for the pucks. 

The system includes two smart pucks that gather data on the patient's range of motion when placed in the compression sleeve.

Detecting Range of Motion

Smart pucks connect through stitched textile sensors in the sleeve to collect data on range of motion to send to the interfaces via bluetooth for the patient and the physical therapist.

Patient App & Physical Therapist Interface

The app tracks progress and guides patients through weekly exercises. Progress from each week is sent to the physical therapist, along with messages, video recordings of the patients exercises, and statistics from the week.

Research and Design Process

Torn Anterior Cruciate Ligament (ACL)

Injury is caused by sudden movements and over-twisting of the knee.

Common injury for athletes involved in soccer, basketball, skiing, tennis and volleyball.



Lasting Effects



Physical Therapy

Electrical Stimulation

Massage Therapy

Reduced Flexibility


Cartilage Damage

Muscle Atrophy

Reduced Dexterity

ACL Injury Patient Journey

The long recovery process post–surgery includes doctor visits, weekly physical therapy, and at-home exercises.

Existing products for ACL injuries address treatment and monitoring separately, but few provide both for the patient.

What if a device could do both?

Slow recovery process

Development of other injuries due to lack of performing exercises correctly

Lack of knowledge on progression of recovery

How could a product monitor range of motion and mobility for patients suffering from an ACL injury? How could it ensure fast recovery, prevent further injury, and provide direct feedback on progress?
