Context: Tendinopathy is a disease state characterized by tendon disorder with pain or decreased function that can cause significant disability. Multiple treatment modalities exist; however, no single treatment is superior. Ultrasound-guided percutaneous needle tenotomy (PNT) and TENEX are emerging as promising treatment options for tendinopathy.

Background: Individuals with Parkinson disease (PD) can improve their overall mobility and participation in daily activities as they engage in frequent exercise. Despite the need for individually tailored exercises, persons with PD often face barriers to accessing physical rehabilitation professionals who can provide them. Telerehabilitation (TR) may facilitate access to necessary and individually tailored rehabilitation for individuals with PD.

Background: Aerobic exercise (AEx) has many potential benefits; however, it is unknown whether individuals with multiple sclerosis (MS) can attain the optimal intensity and duration to harness its effects. Forced-rate exercise (FE) is a novel paradigm in which the voluntary pedaling rate during cycling is supplemented to achieve a higher exercise intensity. The aim of this pilot trial was to investigate the feasibility and initial efficacy of a 12-week FE or voluntary exercise (VE) cycling intervention for individuals with MS.

Importance: Although the cardiopulmonary benefits of aerobic exercise poststroke are well-established, typical stroke rehabilitation does not elicit an aerobic response.

Objective: To characterize heart rate response during upper extremity repetitive task practice (RTP) and determine factors that predict a higher aerobic intensity during RTP.

Design: Secondary analysis of a subset of data from a randomized clinical trial.

Background: The potential for aerobic exercise (AE) to enhance neuroplasticity post-stroke has been theorized but not systematically investigated. Our aim was to determine the effects of forced-rate AE (FE) paired with upper extremity (UE) repetitive task practice (FE + RTP) compared to time-matched UE RTP (RTP only) on motor recovery.

Methods: A single center randomized clinical trial was conducted from April 2019 to December 2022.

Fatigue and pain are prevalent in persons with multiple sclerosis (PwMS), negatively impacting quality of life (QoL). Clinical management is challenging due to their multiple underlying causes. Aerobic exercise elicits central and peripheral effects, which may effectively manage MS-related symptoms.

Background: Stationary cycling is often prescribed for survivors of stroke as a safe means of aerobic exercise to improve cardiovascular health. While cycling is typically not prescribed to restore ambulatory function, improvements in measures of walking after cycling interventions have been reported in the literature.

Objective: To investigate the effects of cycling on walking outcomes in adults with stroke.

Task-specific gait training is recommended to improve locomotor function after stroke. Our objective was to determine the effects of a forced-rate aerobic exercise intervention on gait velocity and biomechanics in the absence of task-specific gait training. Individuals with chronic stroke ( N = 14) underwent 24 sessions of forced-rate aerobic exercise, at a targeted aerobic intensity of 60%-80% of their heart rate reserve.

Background: It is unknown if improvements in gait velocity following an aerobic cycling intervention are accompanied by improved gait biomechanics in individuals with Parkinson's disease (PD) or if gait abnormalities are exaggerated in response to increased velocity. Research question Can an 8-week aerobic cycling intervention elicit improvements in locomotor function in individuals with mild to moderate PD?

Methods: A secondary analysis of data from a randomized clinical trial was conducted in individuals with mild to moderate idiopathic PD (N = 28). Participants were randomized to an aerobic cycling intervention (PD N = 14) consisting of 24 sessions at a targeted aerobic intensity of 60-80% of heart rate reserve or to a no intervention control group (PD, N = 14).

Introduction: Following mild traumatic brain injury, visual dysfunction is a common occurrence, yet the condition often goes undiagnosed. A mobile application was developed to measure aspects of visual acuity and oculomotor function. The aim of this project was to validate the newly developed suite of outcomes conducive for use in the field to detect visual dysfunction.

Introduction: Dual-task performance, in which an individual performs two tasks simultaneously, is compromised following mild traumatic brain injury (mTBI). Proficient dual-task performance is essential in a military setting for both military member safety and execution of skilled tasks. To address the unique needs of military members, a portable dual-task assessment was developed incorporating an auditory dual-task task as a novel assessment module utilizing mobile-device technology.

Understanding deficits in motor control through the analysis of pedaling biomechanics plays a key role in the treatment of stroke patients. A thorough study of the impact of different exercise patterns and workloads on the change between pre- and post-treatment movement patterns in the patients is therefore of utmost importance to the clinicians. The objective of this study was to analyze the difference between pre- and post-treatment pedaling torques when the patients are subject to different exercise groups with varying workloads.

Introduction: Military personnel and civilian athletes are both at risk for mild traumatic brain injury. However, these groups are unique in their training and typical daily activities. A fundamental gap in the evaluation of military personnel following mild traumatic brain injury is the lack of military-specific normative reference data.

Background: The standardization of care along disease lines is recommended to improve outcomes and reduce health care costs. The multiple disciplines involved in concussion management often result in fragmented and disparate care. A fundamental gap exists in the effective utilization of rehabilitation services for individuals with concussion.

. The recovery of motor function following stroke is largely dependent on motor learning-related neuroplasticity. It has been hypothesized that intensive aerobic exercise (AE) training as an antecedent to motor task practice may prime the central nervous system to optimize motor recovery poststroke.

Despite the widespread awareness of concussion across all levels of sport, the management of concussion from youth to college is inconsistent and fragmented. A fundamental gap contributing to inconsistent care is the lack of a scalable, systematic approach to document initial injury characteristics following concussion. The purpose of this study was to determine differences in injury profiles and management of youth, high school, and college athletes using a mobile application for incident report documentation.

The evidence-informed standardization of care along disease lines is recommended to improve outcomes and reduce healthcare costs. The aim of this project is to 1) describe the development and implementation of the Concussion Carepath, 2) demonstrate the process of integrating technology in the form of a mobile application to enable the carepath and guide clinical decision-making, and 3) present data on the utility of the C3 app in facilitating decision-making throughout the injury recovery process. A multi-disciplinary team of experts in concussion care was formed to develop an evidence-informed algorithm, outlining best practices for the clinical management of concussion along three phases of recovery - acute, subacute, and post-concussive.
