In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

Neuromechanics of orthoses refers to how the human body interacts with orthoses. Millions of people in the U.S. suffer from stroke, multiple sclerosis, postpolio, spinal cord injuries, or various other ailments that benefit from the use of orthoses. Insofar as active orthoses and powered exoskeletons are concerned, the technology to build these devices is improving rapidly, but little research has been done on the human side of these human-machine interfaces.
A removable shoe insert, otherwise known as a foot orthosis, orthotic, insole or inner sole, accomplishes many purposes, including daily wear comfort, height enhancement, plantar fasciitis treatment, arch support, foot and joint pain relief from arthritis, overuse, injuries, leg length discrepancy, and other causes such as orthopedic correction and athletic performance. Medical use of foot orthoses has been criticized as lacking evidence of benefit, and practice is very inconsistent: reputed podiatrists prescribe completely different orthoses for a single patient. Further, effect of a given design of orthosis varies significantly by patient, and standard practice to personalize prescription is not available. However, evidence is mixed: patients often report at least short-term improvements in comfort, and other studies have found effectiveness.
Orthotics, also known as orthology, is a medical specialty that focuses on the design and application of orthoses, sometimes known as braces, calipers, or splints. An orthosis is "an externally applied device used to influence the structural and functional characteristics of the neuromuscular and skeletal systems." Orthotists are medical professionals who specialize in designing orthotic devices such as braces or foot orthoses.
An exoskeleton is a wearable device that augments, enables, assists, or enhances motion, posture, or physical activity through mechanical interaction with and force applied to the user's body. Other common names for a wearable exoskeleton include exo, exo technology, assistive exoskeleton, and human augmentation exoskeleton. The term exosuit is sometimes used, but typically this refers specifically to a subset of exoskeletons composed largely of soft materials. The term wearable robot is also sometimes used to refer to an exoskeleton, and this does encompass a subset of exoskeletons; however, not all exoskeletons are robotic in nature. Similarly, some but not all exoskeletons can be categorized as bionic devices. Exoskeletons are also related to orthoses (also called orthotics). Orthoses are devices such as braces and splints that provide physical support to an injured body part, such as a hand, arm, leg, or foot. The definition of exoskeleton and definition of orthosis are partially overlapping, but there is no formal consensus and there is a bit of a gray area in terms of classifying different devices. Some orthoses, such as motorized orthoses, are generally considered to also be exoskeletons. However, simple orthoses such as back braces or splints are generally not considered to be exoskeletons. For some orthoses, experts in the field have differing opinions on whether they are exoskeletons or not. Exoskeletons are related to, but distinct from, prostheses (also called prosthetics). Prostheses are devices that replace missing biological body parts, such as an arm or a leg. In contrast, exoskeletons assist or enhance existing biological body parts. Wearable devices or apparel that provide small or negligible amounts of force to the user's body are not considered to be exoskeletons. For instance, clothing and compression garments would not qualify as exoskeletons, nor would wristwatches or wearable devices that vibrate. Well-established, pre-existing categories of such as shoes or footwear are generally not considered to be exoskeletons; however, gray areas exist, and new devices may be developed that span multiple categories or are difficult to classify.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
