Strengthening of the lateral
peroneus muscles after ankle
sprain
T he purpose of the lateral peroneus
muscles is to maintain the stability of
the ankle joint and prevent it from
rotating inwardly. After a sprain, these
muscles lose their reflex-contraction
capacity together with much of their
strength.
R egaining competent lateral peroneal
muscles after a sprain is a fundamental
step, without which recurrence is very
probable. To do their job correctly, the
lateral peroneals must be strong enough
to prevent the foot twisting inwards, but
they must also contract reflexively at the
precise moment when the heel tilts
inwards.
T o develop both of these aspects,
strength and speed of contraction, you
should use the
Reinforcement
programme, which produces efficient
lateral peroneal muscles and therefore
helps to prevent recurrence.
Duration of the cycle: 4 weeks, 1 x/day
Weeks 1-4: Reinforcement
Week 5 and following weeks:
Reinforcement 1x/week if you take part in
a dangerous sporting activity.
