A reliability test for its efficacy in Smartphone application for Computing joint range of motion: A Research Protocol

Abstract Introduction: "Goniometry" is derived from two Greek words: Gonia, which means "angle," and Metron, which means "measure." The focus of the research is to see if a smartphone-based goniometer application for knee flexion range of motion was reliable. The technology of smartphones is one of the most often used alternatives. A literature evaluation of 12 studies showed that smartphone applications are sufficiently trustworthy to be employed in research and clinical practice. As ROM angulation is widely employed in treatment policy decisions, new measures have to be thoroughly tested before use in clinical practice. The study design used will be an observational study. The participants will be recruited using a simple random sampling method. The total number of participants will be 100 in the age group between 20-60. With Universal Goniometer and Goniometer records, three certified physiotherapists measured maximum active knee flexion in a supine position. Data will be collected and analyzed using SPSS (version: 20) and the Bland Altman Test.Discussion: The goal of this observational study is to examine the reliability of smartphone applications for computing knee joint range of motion.Conclusion: To conclude, this research seeks to examine the reliability of smartphone applications for computing knee joint range of motion in a healthy population. The study findings would help in developing a novel approach for computing and documenting the knee range of motion.

Introduction Diagnostic accuracy is one of the key considerations of telemedicine usage in orthopedic surgery. The aim of this study was to determine the optimal patient positioning to achieve accurate and reliable visual estimation of the knee joint range of motion over a digital platform for telemedicine. Methods A single volunteer was recruited to perform a total of 120 discrete and random knee range of motion angles in three patient positions: sitting, standing and supine. The patient image was broadcast over a digital platform to six raters. The raters recorded their visual estimation of each discrete knee flexion angle independently. After each discrete knee flexion angle, a physical goniometer was used to obtain the actual flexion angle of the knee. Results A total of 120 discrete measurements (40 measurements in the sitting, standing, and supine positions each) were recorded by each of the six raters. The supine position resulted in the highest intraclass correlation of 0.97 (95% confidence interval: 0.98, 0.99). All three patient positions achieved low absolute difference between the goniometer and the raters with 5.6 degrees (95% limits of agreement: −21.0, 9.8) in sitting, 2.7 degrees (95% limits of agreement: −10.1, 15.4), and 1.2 degrees (95% limits of agreement: −9.8, 12.3) in the supine position. The supine position had the highest accuracy and reliability. Discussion Visual estimation of the knee joint range of motion over telemedicine is clinically accurate and reliable. Patients should be assessed in a supine position to obtain the highest accuracy and reliability for visual estimation of the knee joint range of motion during telemedicine.

AbstractThis study aimed to develop a rabbit model of knee contracture in extension and investigate the natural history of motion loss and time-dependent changes in the joint capsule after immobilization. We immobilized the unilateral knee joints of 32 rabbits by maintaining the knee joint in a plaster cast at full extension. Eight rabbits were euthanized at 2, 4, 6, and 8 weeks after casting, respectively, and the lower extremities were disarticulated at the hip joint. Eight control group rabbits that did not undergo immobilization were also examined. We assessed the progression of joint contracture by measuring the joint range of motion, evaluating the histologic alteration of the capsule, and assessing the mRNA levels of transforming growth factor β1 (TGF-β1) in the anterior and posterior joint capsules. After 2 weeks of joint immobilization, the knee joint range of motion was limited, the synovial membrane of the suprapatellar and posterior joint capsules was thickened, the collagen deposition was increased, and the mRNA levels of TGF-β1 were elevated in the anterior and posterior joint capsules. These changes progressed rapidly until 6 weeks of immobilization and may advance slowly after 6 weeks. Joint contracture developed at the early stage of immobilization and progressed over time. The changes in the anterior and posterior joint capsules after joint immobilization may contribute to the limitation in flexion. The elevated mRNA expression of TGF-β1 may be related to joint capsule fibrosis and may be one of the causes of joint contracture.
