What does STEVEN CRENSHAW research?

Dr. Crenshaw studies how to clean up environments contaminated by toxic substances, particularly hexavalent chromium (Cr(VI)). He investigated a specific type of bacteria that can effectively reduce high levels of this harmful chemical in water, making a significant contribution to environmental cleanup methods. Additionally, he researches the effectiveness of specialized ankle-foot braces (orthotics) designed for children with spastic diplegic cerebral palsy, assessing how these devices can influence their ability to walk and whether they truly help in improving mobility.

Key findings

  • The bacteria Bacillus sp. PB2 can remove approximately 90% of hexavalent chromium (Cr(VI)) from water at a concentration of 8,000 micrograms per liter in just 8 hours.
  • Through testing three types of ankle-foot braces, it was found that there were no significant improvements in walking for children with spastic diplegic cerebral palsy after four weeks.
  • His environmental study emphasizes the potential of a natural bioremediation method for addressing serious health risks posed by Cr(VI) contamination.

Frequently asked questions

Does Dr. Crenshaw study environmental pollution?
Yes, he studies the bioremediation of hexavalent chromium, a toxic chemical found in polluted environments.
What treatments has Dr. Crenshaw researched for children?
He has researched the impact of specialized ankle-foot braces on the gait of children with spastic diplegic cerebral palsy.
Is Dr. Crenshaw's work relevant to families affected by environmental contamination?
Yes, his research helps communities understand potential natural solutions for cleaning up hazardous waste, which is relevant for those living near contaminated sites.

Environmental and kinetic parameters for Cr(VI) bioreduction by a bacterial monoculture purified from Cr(VI)-resistant consortium.

Biological trace element research

Okeke BC, Laymon J, Crenshaw S, Oji C

Plain English
This study looked at a type of bacteria called Bacillus sp. PB2, which can survive and reduce the levels of a toxic chemical known as hexavalent chromium (Cr(VI)) found in polluted water and soil. The researchers found that this bacteria can remove about 90% of Cr(VI) from water at a concentration of 8,000 micrograms per liter in just 8 hours, and it works best at a pH of 8.0. This discovery is important because it offers a natural way to clean up environments contaminated with Cr(VI), which is a serious health risk. Who this helps: This helps patients living near contaminated sites and environmental cleanup efforts.

The efficacy of tone-reducing features in orthotics on the gait of children with spastic diplegic cerebral palsy.

2000

Journal of pediatric orthopedics

Crenshaw S, Herzog R, Castagno P, Richards J, Miller F +2 more

Plain English
This study looked at how special ankle-foot braces (orthotics) with features aimed at reducing muscle stiffness affected the walking of eight children with spastic diplegic cerebral palsy, aged 4 to 11. Researchers tested three types of braces over four weeks and found that while the braces changed some ankle movements, there were no clear improvements in walking. This matters because it suggests that simply adding tone-reducing features to braces might not improve gait function for these children. Who this helps: This helps parents of children with cerebral palsy and the healthcare professionals who work with them.
