The objective of this study was to investigate the effects of Heel-Raise-Lower
Exercise (HRLE) interventions on the strength of plantarflexion, balance, and
gait parameters in people with stroke. Specifically, this study compared the two
different HRLEs to identify whether heels raise-lower with forefoot on a block
(HRB) is more effective or ineffective to enhance strength and functional
capacities than heels raise-lower on a level floor (HRL) exercise in people with
stroke. Repetitive heel raise-lower is a common exercise for improving the
strength and power of ankle plantarflexors. It is a simple movement, requires no
equipment, and can be performed at home. Each group of 10 people with stroke was
given either HRB training or HRL training. The subjects performed the exercise
100 times per day, 5 days per week for 6 weeks. The strength of plantarflexors,
static/dynamic balance, and gait parameters were measured using the manual muscle
test (MMT), a Biodex Balance System (BBS) SD, and the GAITRite system. After 6
weeks of treatment, there were significant increases in the plantarflexors
strength in both groups: by 34% in the HRB group and by 21% in the HRL group.
Static and dynamic balance and gait speed also increased significantly in both
groups. However, cadence, the paretic side single limb support period (SLSP),
paretic side step length, and paretic side stride length significantly increased
only in the HRB group. The HRB improved significantly the plantar flexor strength
of the paretic side, gait speed, and cadence compared to the HRL.
