Hardware Specs
Hardware Specifications:
The Tele-Kit must include a:
1. Windows 7 based laptop
a. 32-bit, 2.4 GHz dual core processor
b. USB 2.0 bus
c. At least 2 GB of RAM
2. A suitable Webcam with at least 640 x 480 pixel resolution
3. A Wii remote
4. A Bluetooth Sensor to wirelessly receive the raw data the Wii transmits
5. A Wi-Fi hotspot that fits in the palm of a hand and can provide 3G internet to the laptop
6. The setup time for the Tele-Kit should take less than thirty minutes
a. Detailed, step-by-step instructions must be included
The Hardware for the knee rehabilitation device must:
1. Be safe to use
2. Cost under $200
3. Weigh less than 30 pounds
4. Have variable resistance options depending on patient strength
a. Varying resistance must be easy enough to change with each exercise
5. Allow for range of motion from 0° < θ < 90° (shown in Figure 1)
6. Must accommodate 64 Nm (normalized .97 Nm/kg) to accommodate for the peak torque of the knee joint during extension
7. Fit within a 2 ft. x 2 ft. x 2 ft. Tele-Kit box
8. Must include a carrier for the Wii remote
a. Necessary so the remote can use its accelerometers to extrapolate positional data of the patient’s shin as the knee extends
9. Via the Wii Remote, the hardware must interface with the Tele-process software
10. Additional Design Consideration: including a method of assisting the patient’s leg accounting for a CP patient without full range of motion at the knee

Software Specs
Tele-Process Software
Specifications:
1. Ability to face-time between patient and therapist.
a. High enough quality face-time software to remotely and accurately diagnose the patient
b. The patient diagnoses process will determine:
i. Patient likes and dislikes
ii. Severity of the ailment
iii. Prescription of rehabilitation treatment
2. Software to transform Wii raw data into useable computer keystroke commands
a. Keystroke commands must interface with video games that are:
i. Online
ii. Free
b. The software must be calibrated to a user’s range of motion at the beginning of each therapy session
3. The video games must be:
a. Stored in an organized graphical user interface (GUI) that allows for the therapist to drag and drop applicable games into a specific patient’s therapy profile
b. The interface should house games with previously saved control scheme files
i. This will allow the therapist to quickly tailor the game to an individual’s needs (i.e. change movement magnitudes and game difficulty levels).
1. Setup time should take no longer than 2-3 minutes for already played games.
2. Setup time should take no longer than 10 minutes for new games.
c. The interface should allow for the linking of games in series to provide a full rehabilitation program
i. There must be smooth transitions from one game to the next on the patient end
4. Built-in troubleshooting capabilities
a. Therapist must be able to assume remote control to fix any patient errors
5. Interfacing with an outside Content Management System
a. Used for data transfer between therapist and patient.
b. It must contain:
i. Calendar for milestone recording
ii. Patient and therapist blogging capabilities
iii. Messaging system for patient/therapist communication
6. Patient evaluation capabilities
a. Tracking of metrics such as “number of repetitions”
b. Evaluation must give a score for each metric
c. Patient progress tracking over time
1. Ability to face-time between patient and therapist.
a. High enough quality face-time software to remotely and accurately diagnose the patient
