Back pain can range from a muscle aching to a shooting, burning or stabbing sensation. In addition, the pain may radiate down your leg or worsen with bending, twisting, lifting, standing or walking. The percentage of citizens over the age of 60 in the United States was 8% in 1950, 10% in 2000, and it is estimated to reach 21% .With these projections showing a growing elderly population, and the subsequent number of falls that lead to hospitalization, it is extremely important that research be conducted to identify appropriate solutions associated with mobility issues The most conventional walker frame is the Zimmer frame and because of its basic design, the Zimmer frame assists its users with walking at the cost of long term back strain, pain, and compromising support. The rollator has a differnet design that incorporates a seat and wheels for better moveability yet the weight, cost, stabilty and most importantly back posture is compromised. The upper walker is another type of frame that incoporates the back posture support component yet introduces a problem in the weight, cost, and stability categories. Though modern walkers do exist, improving on Zimmer frame design, they lack a modern use of smart devices and back support . A conclusion of the design of a modern and effective assistive walking device which keeps in mind the assistance provided should not be a source of fatigue and unrest for the user will be presented. An analysis into the back strain present, and the stability of walker designs will be studied to ultimately design The-Franny, a modern walker fitting for the 21st century.
First Stages of Building The-Franny
The Franny started with an idea to incorporate comfrotability, stability, moveability, and most importantly back posture. Not only is The-Franny aiming to complete all these characteristics but also it aims to provide a smart device component which will help the user store and keep track of their heart rate.
In the first iterations of The-Franny it was always present that we wanted to incorporate a comfortability component (the seat), a stability component (the breaks and arm rests), the moveability (the wheels and breaks), and the back support (the height and angle of the frame); all characteristics that can be seen in the early design diagrams above.
