Reducing Recurrent Knee Flexion Contracture by Correcting Leg Length Discrepancy After Total Knee...
OsteoarthritisContractureMoving one's joints through their full range of motion (ROM) is crucial for health and wellbeing. Those who are unable to do so have difficulty carrying out simple activities like walking or feeding themselves. Lost joint ROM is called a contracture. Osteoarthritis (OA) is the most common form of arthritis. About a third of people with knee OA develop knee flexion contractures (KFlCs), the inability to fully straighten the knee. Having a KFlC before a knee replacement is a big risk factor for redeveloping one after the operation. Many people with a KFlC in the knee for surgery also have a KFlC in the other knee. The investigators believe that this non-surgical KFlC increases the risk of re-developing a KFlC in the surgical knee after surgery by encouraging bending of the surgical knee to avoid one leg being shorter than the other. No one has ever looked at whether fixing this leg length difference using a shoe lift would prevent this problem and there is little information to help design such a study. Here the investigators will see if testing shoe lift use for preventing KFlC is feasible. The investigators hypothesis is that a study evaluating the benefit of using a shoe lift to correct leg length difference in the non-surgical knee is feasible.
Investigations of Mechanisms and Treatment in Post-traumatic Joint Contractures
Joint ContracturesInjured joints, especially at the elbow, are at risk for permanent motion loss, also known as joint contractures. Joint contractures limit the function of an elbow and are a recognized complication that occurs often after a traumatic injury. The benefits of early motion after injury has helped in preventing joint contractures but there are still several patients that develop debilitating joint contractures. Current research suggests that mast cells, which are found in the joint, are key in causing joint contractures. Research has been done using a medication called Ketotifen. Ketotifen has been linked to stabilizing mast cells and preventing the joint contracture. It is hoped that short-term use of this medication after an injury will prevent the contracture from occurring.
The Effect of Aerobic Exercise, on Fitness and Functional Muscle Strength, in Patients With Muscular...
Bethlem MyopathyMuscular dystrophy is a group of disorders that are characterized by progressive muscle weakening and loss of muscle mass, caused by defects in muscle proteins. Muscular dystrophy is almost always inherited disorders, and so far, no curative treatments exist. Previous studies have shown that endurance training significantly improves fitness and self-assessed muscle function in a variety of muscular dystrophies. In this study, we wish to investigate whether patients with Bethlem myopathy (a specific form of muscular dystrophy) also benefit from endurance training. The study consists of two test days, a 10-week training period and five blood tests. Patients will be required to train, three times per week, for 10 weeks, on a bike ergometer with a specific training intensity, under pulse rate monitoring. The training period will be flanked by two test days, where we will determine, and compare the patients' muscle strength and fitness level, from before to after the training program. The patients conditioning level will be determined from a 15 minute cycle ergometer test and patients will undergo three functional tests to determine their functional muscle strength. We will as a safety measure analyze blood tests before, during and after the training program for the muscle enzyme creatine kinase (an indicator of muscle damage) and through adverse effects as reported by patients during weekly telephone-consultations with the Principal investigator. We anticipate, that Bethlem myopathy patients will have a similar rise in fitness level and functional muscle strength, as that seen in patients with other forms of muscular dystrophy, who undertake a similar training program.
Glenohumeral Rotation After Throwing: RCT Comparing the Sleeper Stretch to the 90/90 Hip Lift With...
Internal Rotation Contracture-shoulderThe primary purpose of this study is to determine if the loss of internal rotation following a throwing session is best restored through soft tissue stretching with the sleeper stretch or with scapular repositioning with the 90/90 hip lift with balloon blow exercise. This study will progress the body of research related to internal rotation deficits with regards to baseball throwers. The research will be relevant to clinicians who treat patients with baseball players with internal rotation loss. High school baseball players will be the targeted subjects for this study. They will perform two exercises (one per week) designed to increase shoulder internal rotation over the course of three weeks with one week of rest between intervention weeks. The primary outcome will be shoulder internal rotation range of motion improvements over the course of one week's time. There are no known adverse risks to either intervention.

Determining the Reliability and Validity of a New Method for Measuring Upper Extremity Joint Range...
Contracture JointIn burn patients, joint contracture is a common complication caused by hypertrophic scars, necessitating accurate evaluation and diagnosis of the degree of disability and functional deterioration. A standard goniometer based on the American Medical Association (AMA) guidelines for measuring joint range of motion (ROM) is the gold standard for evaluating musculoskeletal diseases. However, the handheld goniometer is highly dependent on the skill and experience of the measurer. Recently, a marker-based system for accurate ROM measurement has been demonstrated in clinical evaluation. This study investigated the reliability and validity of the marker-based system for evaluation of joint ROM in burn patients. Inclusion criteria were as follows: male or female patients between 18 and 75 years of age, partial or full-thickness burns that healed spontaneously or required skin grafting, and limited joint ROM in the upper extremities caused by burns. Exclusion criteria were limited joint ROM due to severe osteoarthritis or rheumatoid arthritis, congenital defects, structural disease, amputation, central or peripheral nervous system injuries, difficulty in voluntary decision-making due to cognitive impairment, or a history of orthopaedic surgery due to fracture. The experimentals tried to compare the validity and reliability of a marker-based system and AMA methods for the burn patient with joint contracture of upper extremities.

A Pharmacokinetic Study of AA4500 (XIAFLEX™, Proposed Name) in Subjects With Dupuytren's Contracture...
Dupuytren's ContractureA Phase 1, open-label, single-dose pharmacokinetic study in subjects with Dupuytren's contracture conducted at one site in the United States. All subjects received a single dose of AA4500 0.58 mg, which was injected directly into the cord affecting either the metacarpophalangeal (MP) or proximal interphalangeal (PIP) joint. Pharmacokinetic blood samples were collected before dosing, at predetermined time points through the 24 hours after dosing, Day 7, and Day 30. Efficacy and safety assessments were performed up to 30 days after the AA4500 0.58 injection. This study was designed to be part of the larger clinical program, for adult patients with Dupuytren's contracture with a palpable cord, where the data from 2 pivotal Placebo-Controlled studies (AUX-CC-857 [NCT00528606]and AUX-CC-859 [NCT00533273]) and 7 non-pivotal studies were evaluated.
Robotic Sock Technology for Prevention of Deep Vein Thrombosis and Joint Contracture
Deep Vein ThrombosisAnkle Joint ContractureThe research team's aim is to investigate the effects of the team's soft robotic socks in providing assisted ankle dorsiflexion-plantarflexion and promoting venous blood flow in stroke patients. Specifically, the investigators intend to 1) observe the development of joint contracture in terms of the range of motion of the ankle joint given the use of the device 2) monitor the presence of blood clots in the deep veins using compression Duplex ultrasonography given the use of the sock device. The investigators hypothesize that a soft robotics approach can provide compliant actuation to simulate natural ankle dorsiflexion and plantarflexion, which will consequently promote blood circulation in the lower leg of stroke patients who have not previously developed ankle joint contracture. This will prevent the occurrence of DVT and movement in the ankle joint will alleviate stiffness. This robotic sock intervention is to prevent the development of ankle joint contracture so established ankle contractures will be excluded from this study.
