Predicting Outcomes of Treatment for Stiff-knee Gait Using Supervised Learning
نویسندگان
چکیده
Stiff-knee gait is a prevalent, debilitating consequence of cerebral palsy in which swingphase knee flexion is substantially diminished. Approximately 3 out of every 1,000 children manifest one or more of the symptoms of cerebral palsy (CDC, 2004). Stiff knee gait results in a number of related gait problems including tripping and foot-dragging due to inadequate toe clearance (Sutherland and Davids, 1993).

Predicting outcomes of rectus femoris transfer surgery.
Rectus femoris transfer surgery is a common treatment for stiff knee gait in children with cerebral palsy. Unfortunately, the improvement in knee motion after surgery is inconsistent. There is great interest in understanding the causes of stiff knee gait and determining predictors of improved knee motion after surgery. This study demonstrates that it is possible to predict whether or not a pati...
متن کاملImportance of preswing rectus femoris activity in stiff-knee gait.
Stiff-knee gait is characterized by diminished and delayed knee flexion during swing. Rectus femoris transfer surgery, a common treatment for stiff-knee gait, is often recommended when a patient exhibits prolonged activity of the rectus femoris muscle during swing. Treatment outcomes are inconsistent, in part, due to limited understanding of the biomechanical factors contributing to stiff-knee ...
متن کاملKinematic and kinetic factors that correlate with improved knee flexion following treatment for stiff-knee gait.
Stiff-knee gait is a movement abnormality in which knee flexion during swing phase is significantly diminished. This study investigates the relationships between knee flexion velocity at toe-off, joint moments during swing phase and double support, and improvements in stiff-knee gait following rectus femoris transfer surgery in subjects with cerebral palsy. Forty subjects who underwent a rectus...
متن کاملRectus femoris to gracilis muscle transfer with fractional lengthening of the vastus muscles: a treatment for adults with stiff knee gait.
BACKGROUND Stiff knee gait, which may be seen in patients with upper motor neuron injury, describes a gait pattern with a relative loss of sagittal knee motion. It interferes with foot clearance during swing, often leading to inefficient compensatory mechanisms and ambulatory dysfunction. Distal rectus femoris muscle transfers and fractional lengthening of the vastus muscles have been performed...
متن کاملThe importance of swing-phase initial conditions in stiff-knee gait.
The diminished knee flexion associated with stiff-knee gait, a movement abnormality commonly observed in persons with cerebral palsy, is thought to be caused by an over-active rectus femoris muscle producing an excessive knee extension moment during the swing phase of gait. As a result, treatment for stiff-knee gait is aimed at altering swing-phase muscle function. Unfortunately, this treatment...
