Write “letter to shoe company” on your bell work sheet. Then write the letter on a sheet of notebook paper. Individually, write a letter to the Fast Feet Shoe Company recommending the amount of models their company needs to make. Don’t forget to base your recommendation on data and research. Also include the parts of the running shoe that your findings will impact the most, being specific for each foot/shoe type. *HINT: Look at your own shoe for helpful information Bell Work: 3/4/15

Standards SPI 0707.T/E.3 Distinguish between the intended benefits and the unintended consequences of a new technology. SPI 0707.T/E.4 Differentiate between adaptive and assistive bioengineered products. SPI Explain the basic functions of a major organ system. What are the intended benefits and the unintended consequences of the new technology? Are we able to differentiate between adaptive and assistive bioengineered products? What is the basic function of the skeletal and muscular systems? How do they work together for survival? Essential Questions

Biomedical engineers use their knowledge of the human body to design technologies to solve problems related to biology, health, and medicine. Biomedical engineers collect and analyze data about the human body to help inform the design of various technologies, such as prosthetics and pacemakers. In this challenge, you and your team will take on the role of a biomedical engineer as you collect data for an athletic shoe company, design and create knee braces for an injured knee, and design and create biomechanical equipment for a specific sport. Your team will focus on the muscular and skeletal systems (i.e. musculoskeletal system) and how they interact with one another. Your knee brace must support a model injured knee to enable it to move like a healthy knee, while at the same time being cost- effective. The biomechanical equipment for a specialized sport must either enhance performance or prevent injury, while also being cost-effective.

Restate your problem State what you already know List any limitations or controls

Research the following topics: Biomedical engineering or bioengineering Biomechanics External parts of the foot Muscular and skeletal systems—specifically how they interact with one another Internal parts of the knee Action research on foot shapes, sizes, and arch heights Knee braces Your selected sport & biomechanical equipment Brainstorm ideas with your team for each problem.

Goal: To work as biomedical engineers to design a knee brace for a model of an injured knee. Your knee brace has to help the injured knee move like a healthy knee. What do you need to know before you start designing your knee braces? Examples: What materials do we have available? How is the knee injured—what is wrong with it? How should a healthy knee move? What is the budget we have available?

Your team will use a goniometer to measure “how far” you can bend your lower leg at the knee in different directions. 1. Stand and hold on to your table or chair for balance. Bend your right, lower leg backwards at the knee as far as you can. 2. Align the circular section of the goniometer with the side of your knee and the two straight sections with the upper and lower parts of the leg. 3. The arrow on the lower section of the goniometer will point to a zone. Record this zone number on the Range of Motion Summary sheet. 4. Repeat for the front of the knee as well.

What movements does a healthy knee allow? Based on our results, what zone would you say the range of motion of a healthy human knee bending backwards falls into? What similarities did you notice between your range of motion and the injured model knee? What differences did you notice? How will our new knowledge help us with the design challenge? What unhealthy movements do you think your knee brace design needs to correct? How could we figure out if our knee brace designs successfully helped the injured knee model move like a healthy knee?
