Proprioception exercise intervention. The proprioception
exercise protocol emphasized
static and dynamic balance exercises, including
transitions between differing sensory
conditions and functional everyday movements.
Each session incorporated a similar
general plan: (1) warm-up; (2) static balance
exercises, such as squats (two-leg stance) and
one leg stance; (3) dynamic balance exercises
such as jogging end to end, sideways walking
or running with crossovers, forward walking
or running in a zigzag line, and backward
walking or running in a zigzag line; (4) cooldown.
The warm-up and cool-down sessions
were carried out as described above. During
the 8 weeks of the study, exercises gradually
increased in difficulty and training load on
an individual basis, if the subject felt the
exercises were too easy
