The primary research interests of John H. Hollman, Ph.D., include the study of lower extremity biomechanics and gait mechanics during walking.

Regarding lower extremity biomechanics, Dr. Hollman's studies focus on the relationships between hip, knee and foot and ankle biomechanics during weight-bearing activities. In particular, he studies how hip muscle function influences motions that may lead to lower extremity injuries, such as those to the anterior cruciate ligament and patellofemoral joint.

With regard to gait mechanics, his studies focus on quantifying gait instability and understanding how gait instability influences one's risk of falling.

Focus areas

  • Risk factors for knee injury. Dr. Hollman is interested in understanding how impaired hip muscle strength and impaired hip muscle motor control uniquely contribute to abnormal motions that may cause knee injuries.
  • Gait instability and fall risk. Dr. Hollman studies how gait instability may increase risk of falls, particularly in older individuals.

Significance to patient care

Dr. Hollman's research will help athletes reduce their risk of knee injury or other lower extremity injuries and, if injured, enhance their rehabilitation and recovery following a lower extremity injury.

Similarly, his research will help older individuals reduce their risk of falling while walking.
