1. Taghavi, Nazita. A device for sensing and balance augmentation using functional electrical stimulation.

Degree: 2020, Iowa State University

Based on World Health Organization (WHO) report, between 250,000 and 500,000 people suffer from disabilities caused by spinal cord injuries each year. The result of this study is development of a medical device to restore walking in such patients using Functional Electrical Stimulation (FES). We selected dogs as our animal subject. This device uses FES to prevent an affected dog with limited walking abilities from falling during walking. The final version of the device includes a sensing core consisted of four Inertial Measurement Units (IMUs) attached to the hip, femur, tibia and metatarsus of our test subject. Using this sensory system, the device tracks and measures the hip, knee and hock joint angles in real time. We use a commercial microcontroller as our analytical core to provide suitable stimulation commands and provide appropriate voltage/current for delivery to target muscles. Data from IMUs are received by microcontroller using I2C bus communication. An advanced embedded C code is developed to program the microcontroller. We discuss a method to recognize the swing and stance phases of the dog gait during walking and propose several balancing strategies to be used for gait control during the stance and swing phase before falling occurs. We design and build a robodog to be compatible with the medical device. We use this robot to program and test the different cores of the device. We test our balancing strategies on our bionic test-bed before applying them on an actual animal subject. Results show the device can provide suitable sensing and stimulation control to balance the body of a dog that has limited ambulation abilities.

2. Furse, Alexander. Development of a Low Cost Swing-phase Control Mechanism.

Degree: 2010, University of Toronto

Seven above-knee amputees were fitted with a low-cost prosthetic knee and different low-cost swing-phase setups were clinically assessed. Clinical testing included the 20-meter walk tests utilizing a mobile computer setup connected to a potentiometer and accelerometer mounted on the prosthetic limb. As hypothesized, incorporating friction and a spring system resulted in improved gait function. Of the two spring systems evaluated, the dual spring system performed better than the single spring system resulting in increased walking velocity with decreased maximum flexion and terminal impact. The dual spring system resulted in lower terminal impact because the deactivation of the stiff spring and activation of the less stiff spring during the last 25 degrees of swing-phase before extension allows the shank to decelerate and hit the bumper at a lower velocity. The swing-phase control mechanisms evaluated have the potential to improve prosthetic function and are ideal for use in low-cost and peadiatric prostheses.

3. Selles, Ruud. Weighing weight : effect of below-knee prosthetic inertial properties on gait.

Degree: 2002, Erasmus University Medical Center

textabstractIn this thesis, the influence of prosthetic inertial properties (mass, mass distribution and moment of inertia) on the gait of transtibial amputation (TTA) subjects is studied. Chapter 1 introduces the present ideas on prosthetic mass. It describes that the general design effort has always been, and still is, to reduce prosthetic mass. However, as far as we know, lightweight design has never been advocated in the present literature. The Chapter introduces the opposite view, found in a relatively large body of literature, that lightweight design might not be beneficial for prosthetic gait. The aim of this thesis, therefore, is to determine the optimal inertial properties of the prosthetic leg.

Subjects/Keywords: below-knee prostheses; equations of motion; human walking; prosthetic mass; swing phase during gait; tibial
