To determine whether proprioception or muscular strength is the dominant factor in balance and joint stability and define what type of ankle rehabilitation is most effective for these purposes.
The University of North Carolina Sports Medicine Research Laboratory.
Thirty-two healthy volunteers free of head injury, dominant leg injury, and vestibular deficits.
Subjects were divided into control, strength-training, proprioceptive-training, and strength-proprioception combination training groups. Balance was assessed before and after 6-week training programs.
Static, semidynamic, and dynamic balance were assessed.
Subjects showed no improvement for static balance but improved significantly for semidynamic (P = .038) and dynamic (P = .002) balance. No significant differences were observed between groups.
Enhancement of proprioception and muscular strength are equally effective in promoting joint stability and balance maintenance. In addition, no 1 type of training program is superior to another for these purposes.
