LegTutor Enhances Range of Motion for Knee Replacement Patients

Pazit Levinger etal conducted a study published in Springer Link in October 2011.
The purpose of the study was to determine why knee pain and disability persists following knee replacement surgery which may place patients at increased risk of falls. This study investigated the falls risk and the occurrence of falls of people with knee osteoarthritis (OA) before and at 12 months following knee replacement surgery.
The method used in the study was:
Thirty-five patients with knee OA were tested prior to undergoing knee replacement surgery and at 12 months following surgery using the short form Physiological Profile Assessment, which incorporates tests of vision, lower limb proprioception, knee extension strength, reaction time and postural sway. Physical activity, number of falls, fear of falling, pain, disability and health-related quality of life were also assessed.
The results showed that there were no significant differences found between the number of falls pre- and post-surgery (n.s.), with 48.5 and 40% reporting at least one fall in the 12 months before and following the surgery, respectively. Improvements in knee strength, reaction time and fear of falling were evident following surgery, with no improvement in lower limb proprioception. Self-reported pain, function and stiffness were significantly improved, but health-related quality of life deteriorated following the surgery.
The conclusion reached was that the number of falls experienced following knee replacement surgery remained relatively high, which may be attributed to the persistence of impaired lower limb proprioception. Although knee replacement surgery improves function and alleviates pain, people who undergo this procedure may need to engage in rehabilitation following the surgery to reduce the risk of falling.
The LegTutor has shown remarkable success in post knee replacement surgery. The LegTutor™ system has been developed to allow for functional rehabilitation of the lower extremity. The system consists of an ergonomic wearable leg brace and dedicated rehabilitation software. The LegTutor™ allows for a range of biomechanical evaluation including speed, passive and active range of motion and motion analysis of the lower extremity. Quantitative biomechanical data allow for objective evaluation and rehabilitation treatment follow up. The LegTutor™ rehabilitation concept, which includes the HandTutor, ArmTutor and 3DTutor, is based on performing controlled exercise rehabilitation practice at a patient customized level with real time accurate feedback on the patient’s performance. The exercises are designed in the form of challenging games that are suitable for a wide variety of neurological and orthopedic injury and disease.The games challenge the patient to perform the exercise task to their best ability and to continue exercise practice.
The LegTutor™ allows for isolated and a combination of knee and three directional hip treatment. The system provides detailed exercise performance instructions and precise feedback on the patients exercise performance. Controlled exercise of multi joints within the normal movement pattern prevents the development of undesired and compensatory joint movement and ensures better performance of functional tasks.
The LegTutor™ system is used by many leading rehabilitation centers worldwide and has full FDA and CE certification and is available for adults and children.
