A Randomized Clinical Trial To Compare The Effect Of Non Operative Treatment With And Without Autologous Conditioned Plasma (Acp) On Healing And Function In Patients With Achilles Tendon Ruptures, Tyler M. Pratt

Electronic Thesis and Dissertation Repository

The purpose of this study was to determine whether there is evidence to support conducting a larger randomized control trial (RCT) to compare the non-operative treatment of Achilles tendon (AT) ruptures with or without Autologous Conditioned Plasma (ACP®). Twenty-four patients were randomized to receive an ACP® or saline injection within seven days and again at two weeks post-rupture. Tendon healing was longitudinally evaluated using ultrasound (US) and magnetic resonance imaging (MRI). Functional and patient-reported quality of life measures were also assessed. A small sample size limited our ability to detect statistically significant differences. The mean rankings of healing were slightly …

Utility Of Ultrasound For Imaging Osteophytes In Patients With Insertional Achilles Tendinopathy, Ruth L. Chimenti, Peter C. Chimenti, Mark R. Buckley, Jeff R. Houck, A. Samuel Fleminster

Faculty Publications - College of Physical Therapy

Objectives: To examine (1) the validity of ultrasound imaging to measure osteophytes and (2) the association between osteophytes and insertional Achilles tendinopathy (IAT).

Design: Case-control study.

Setting: Academic medical center.

Participants: Persons with chronic unilateral IAT (n=20; mean age, 58.7±8.3y; 10 [50%] women) and age- and sex-matched controls (n=20; mean age, 57.4±9.8y; 10 [50%] women) participated in this case-control study (N=40).

Interventions: Not applicable.

Main Outcome Measures: Symptom severity was assessed using the Foot and Ankle Ability Measure, the Victorian Institute of Sport Assessment-Achilles questionnaire, and the numerical rating scale. Length of osteophytes was measured bilaterally in both groups using …

Eccentric Loading Of Triceps Surae Modulates Stretch Shortening Cycle Behaviour - A Possible Therapeutic Mechanism, J Debenham, W Gibson, M Travers, A Campbell, G Allison

Physiotherapy Papers and Journal Articles

Context: Eccentric exercises are increasingly being used to treat lower limb musculoskeletal conditions such as Achilles tendinopathy. Despite widespread clinical application and documented efficacy, mechanisms underpinning clinical benefit remain unclear. Positive adaptations in motor performance are one potential mechanism.

Objective: To investigate how an eccentric loading intervention influences measures of stretch-shortening cycle (SSC) behaviour during a hopping task.

Design: Within subjects repeated measures observational study.

Setting: University motion analysis laboratory.

Participants: Healthy adults. Interventions: A single intervention of 5 sets of 10 eccentric plantarflexion contractions at 6 RM using a commercial seated calf raise machine.

Main outcome measures: Lower limb …
