Bilateral and unilateral training equipment for the upper limbs
facilitates rehabilitation after stroke. In this work, we tested the first device
designed for bilateral training of the lower limbs.
METHOD: Characteristics and
usage of the novel MedExercise(R) ST device were evaluated by four healthy
volunteers. A pedometer and temperature sensor were attached to the device and
used to measure cadence and intensity of training, respectively. The heart rates
of participants were recorded with a fingertip pulse oximeter. Thirty elderly
patients assessed usability of the device and completed the survey. RESULTS: It was shown that the device could be operated in sitting and recumbent positions.
The resistance levels and range of joint motion were individually adjustable for
each leg, allowing both bilateral and unilateral training. When pedals were
linked together, one leg could help moving the other leg. Recording of training
intensities allowed leg fitness testing, personalized exercise prescription and
analysis of self-controlled training. A usability survey demonstrated positive
perception of elderly patients towards the device.
CONCLUSIONS: This training
system has a range of useful features, which can facilitate rehabilitation of the
lower limbs via early leg mobilization and self-controlled training. Implications
for Rehabilitation Bilateral and unilateral training devices are widely used to
improve the effectiveness of upper limb rehabilitation, but there is no analogous
equipment available for the lower limbs. Here, we show that the MedExercise(R) ST
training system allows independent exercise of each leg in bilateral and
unilateral modes, and objective recording of training activities. Elderly
patients attending the exercise rehabilitation clinic demonstrated a positive
perception towards usability of this equipment.
The results of this study suggest
suitability of the system for optimization of lower limb rehabilitation,
including early leg mobilisation and self-controlled training.
