Purpose: 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® 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® 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.
