Functional knee braces (FKB) are used prophylactically and in rehabilitation to aide in the functional stability of the knee.
To determine if alterations in select lower extremity moments persist throughout a one hour period in healthy individuals.
2X5 repeated measures design.
Twenty subjects (14 male and 6 female, mean age 26.5±7 yrs; height 172.4±13 cm; weight 78.6±9 kg), separated into braced (B) and no brace (NB) groups.
A one-hour exercise program divided into three 20 minute increments.
Main Outcome Measures:
Synchronized three-dimensional kinematic and kinetic data were collected at 20-minute increments to assess the effect of the FKB on select lower extremity moments and vertical ground reaction forces.
Increase in hip moment and a decrease in knee moment were noted immediately after brace application and appeared to persist throughout a one hour bout of exercise.
The FKB and the exercise intervention caused decreases in knee joint moments and increases in hip joint moments.
