The research seeks to determine the following: (1) whether the therapeuticeffects of different types of functional postoperative treatment of Achilles tendon repair, including castimmobilization and functional orthosis, reflect on aspects of the calf muscle and tendon; (2) whetherpost-surgery microcirculation in the Achilles tendon can be manipulated by vibration massage; and (3) whether anearly intervention of vibration massage after an Achilles tendon repair can improve outcomes afterwards.Furthermore, our research interests include the establishment of a model of human tendon healing afterincision, as well as an improved understanding of the characteristics of tendon microcirculation insubjects with hyperglycemia for the purposes of tendon healing and injury prevention. In the first year of the project, subjects who have undergone a unilateral Achilles repair within the last year will berecruited. These subjects will be divided into either a cast immobilization group or a functional orthosis groupaccording to the type of post-surgery management they received. In the first year of the project, 15 subjects will berecruited for each group. The research aims to compare the therapeutic effects of the two aforementioned types ofpost-surgery immobilization in terms of the following: muscle fascicle morphologies, fascicular behaviors, andforce during isometric, concentric, and eccentric contraction; the mechanical properties of the tendinous tissuesincluding the proximal aponeurosis and the Achilles tendon; muscle activation; functional performance in thelower extremities; and the subjective assessments of the subjects with a unilateral Achilles tendon repair.Furthermore, bilateral comparisons between the injured and non-injured legs will be made in the first year of theresearch project to investigate whether there are significant bilateral differences within each group.For the second year of the project, subjects who have undergone a unilateral Achilles repair within the last monthwill be recruited. Those subjects will then be randomly divided into a vibration massage group or a no-vibrationgroup. For this portion of the research, 15 subjects will be recruited for each group. This portion of the project aimsto investigate both the acute and chronic effects of, respectively, a short-term and a long-term mechanical vibrationmassage intervention on Achilles tendon microcirculation. In addition, for another part of the project, subjects witha unilateral cruciate ligament rupture in the knee joint will be recruited for a ligament reconstruction with a patellartendon autograft. The microcirculatory and mechanical changes in the autografted patellar tendon will then beobserved at 1, 2, 3, 6 and 9 months post-reconstruction surgery for comparison with condition of the tendon priorto the reconstruction. Bilateral comparisons between the autografted and healthy patellar tendons will also be made.The aims of this portion the research project are to understand and establish the characteristics of microcirculationand mechanical recovery after a tendon incision in the human patellar tendon.In the third year of the project, the second-year portions of the project described above will be extended to includemeasurements of the therapeutic effects of post-surgery vibration massage at 3, 6, and 9 months post-surgery onthe outcomes measured during the first year of the project, such as muscle fascicle morphologies and behaviors,the mechanical properties of the tendinous tissues, functional performance, and subjective assessments. In addition,30 male subjects with hyperglycemia and 30 controls will be recruited. This part of the research aims to measurethe microcirculatory and mechanical characteristics of the patellar and Achilles tendons in the subjects withhyperglycemia, as well as the differences between the two groups.肌腱修補型態力學微循環肌腱癒合高血糖tendon healingbiomechanicsmicrocirculationtendon rupturehyperglycemia
