Abstract
Background and purpose: Weight-bearing exercises can help improve physical function; however, they may be difficult to perform in patients with neurological issues or lower limb fractures. The purpose of this study was to evaluate the activity of the leg muscles during squatting when using a new exercise aid designed to help patients with difficulty in performing squats, termed the sliding tilt table, at different knee angles and to estimate the squat level for each angle.
Methods: This study was a cross-sectional, observational study performed in the general community. Participants comprised 30 healthy adult men. Squats were performed by setting the knee joints at 30, 60, and 90° and the tilt table angles to 15, 30, and 45°. The muscle activity of the vastus medialis, tibialis anterior, and gastrocnemius was measured using surface electromyography.
Results: As the tilt table and knee joint angle increased, the %maximal voluntary isometric contraction increased. Similar patterns were found in both legs.
Conclusions: Weight-bearing exercises, such as squats, are important exercise elements in patients who require lower limb rehabilitation. Therefore, it is necessary to provide efficient lower limb rehabilitation exercises by adjusting the squat level according to the patient's ability, which can be achieved using a sliding tilt table.
期刊介绍：
Physiotherapy Research International is an international peer reviewed journal dedicated to the exchange of knowledge that is directly relevant to specialist areas of physiotherapy theory, practice, and research. Our aim is to promote a high level of scholarship and build on the current evidence base to inform the advancement of the physiotherapy profession. We publish original research on a wide range of topics e.g. Primary research testing new physiotherapy treatments; methodological research; measurement and outcome research and qualitative research of interest to researchers, clinicians and educators. Further, we aim to publish high quality papers that represent the range of cultures and settings where physiotherapy services are delivered. We attract a wide readership from physiotherapists and others working in diverse clinical and academic settings. We aim to promote an international debate amongst the profession about current best evidence based practice. Papers are directed primarily towards the physiotherapy profession, but can be relevant to a wide range of professional groups. The growth of interdisciplinary research is also key to our aims and scope, and we encourage relevant submissions from other professional groups. The journal actively encourages submissions which utilise a breadth of different methodologies and research designs to facilitate addressing key questions related to the physiotherapy practice. PRI seeks to encourage good quality topical debates on a range of relevant issues and promote critical reflection on decision making and implementation of physiotherapy interventions.
