Sandra Anstaett Metzler | Mechanical Engineering 4905 | The Ohio State University | ME 4905 What makes this capstone sequence different? Rehabilitation engineering is the use of engineering science and principles to Develop technology and devices to assist individuals with disabilities Aid the recovery of physical and cognitive functions lost because of disease or injury Many projects in this capstone sequence from previous years have pertained to: Wheelchair attachments, adaptations or measurement systems Surgical devices Adapted equipment such as tricycles or sports equipment Transfer aids Assistive tools to help stroke patients with daily living …A lot more!

Sandra Anstaett Metzler | Mechanical Engineering 4905 | The Ohio State University | Recent Projects Patient sling lift Transfers to and from a wheelchair are often performed with the assistance of a patient lift. Many of these devices place the patient in a position that is uncomfortable and can be insecure. This team redesigned the lift to be so secure that it could be used to for transfers into and out of a bathtub, in a more upright, sitting posture. Design of a more secure, comfortable & supportive sling for patient transfer device.

Sandra Anstaett Metzler | Mechanical Engineering 4905 | The Ohio State University | Recent Projects Pediatric tricycle for children with achondroplasia Achondroplasia is a genetic condition that results in short stature, as well as shorter arm and leg lengths Children with achondroplasia are often unable to ride normal tricycles due to their unique anthropometry, but still need to play, just like any other child. This group designed a tricycle with geometry that is suitable for the unique anthropometry of children with achondroplasia.

Sandra Anstaett Metzler | Mechanical Engineering 4905 | The Ohio State University | Recent Projects Off-road wheelchair device This group developed a reasonably priced device that can be attached to a manual wheelchair Client was a farm that held camps for children with chronic illnesses Allows a caregiver to navigate rough, hilly, or uneven terrain more easily, allowing access to a wider range of environments and activities

Sandra Anstaett Metzler | Mechanical Engineering 4905 | The Ohio State University | SmartHub Manual wheelchair users often experience pain and overexertion injuries to their shoulder from the repetitive motion associated with self propulsion. This group developed an exercise & fitness tracking device, much like a FitBit for wheelchair users. Recent Projects

Sandra Anstaett Metzler | Mechanical Engineering 4905 | The Ohio State University | Each group has an engineering advisor and a clinical/medical advisor. Opportunity to work in a medical environment on current real-world problems. Products are tested in the clinic with medical professionals and patients. Many of the designs are incorporated into the clinical setting during or after the course. Make a difference while learning the process of design! Unique features & benefits ME 4905
