Project Overview

Physical Therapy patients who train on stationary bicycles can have trouble transitioning to a free standing bicycle due to a difficulty in balancing. For patients whose end goal is to be able to return to riding a freestanding bicycle, an intermediate step would be helpful in providing balance training. This device would be less stable than a stationary bicycle, and would allow PT patients to improve their balance. This type of therapy can also be used for individuals who wish to improve their balance and have no desire to ride a freestanding bicycle. The end goal of the project will be to design and build a system that can be used in the Physical Therapy Clinic at Nazareth College to help patients improve balance by simulating the instability of a freestanding bicycle without the risks associated with actual bike riding. This project has two primary challenges:

1. Developing a system with dynamics mimicking those experienced on a traditional bicycle
2. Finding a way to provide meaningful feedback to the patient and therapist during a bike training session

Benchmark Products

The Schwinn Airdyne Exercise Bike is currently used at the Nazareth College physical therapy clinic for aerobic training. The pedal resistance is controlled by a wind fan. Resistance is exponential and dependant on the pedalling speed.

---

The Kinetic Rock 'n Roll is an indoor cycling trainer to be used with a road bike. It allows the bike to move side to side as the rider pedals to create more realistic training conditions. This is the only indoor trainer that simulates the out-of-the-saddle hill climb movement of a cyclist.

---

The Stability Ball is used in a variety of balance training exercises to strengthen core muscles. This is the only balance training tool The Nazareth College physical therapy clinic currently has access to for improving the balance capabilities of current patients.

---

The Balance Board is another commonly used balance training device used in physical therapy clinics.

---

The AngleStar Electronic Protactor System uses an inclinometer to measure tilt angle with respect to gravity.
