Projects

  1. Pilot Project Grant from the parent award: 1U54GM104944-01

    Role: Co-Investigator (PI: Mays RJ)

    Awarding Institution: Sub-award from the University of New Mexico

    National Institutes of Health (NIGMS)  (PI: Langer R with UNM)                        

    Title: Community-based walking exercise enhanced by orthoses to improve walking ability in patients with peripheral artery disease

    Dates: 07/01/2014 - 6/30/2015

    Aim: We will test the hypotheses that using carbon fiber ankle foot orthosis (AFO) with patients who have intermittent claudication from peripheral artery disease (PAD) will reduce barriers and improve the efficacy of community walking exercise.

  2. New Investigator Grant

    Role: Co-PI (PI: Elias ARC)

    Awarding Institution: Orthopaedic Section of the American Physical Therapy Association

    Title: A clinical trial to improve motor learning in plyometric training post-ACLR via a novel body-weight support system

    Award Dates: 5/15/2014 – 5/14/2015

    Aim: To determine if high volume jump training with reduced loading intensity will preferentially enhance motor learning for improved load attenuation compared to standard jump training.

  3. Miami-Marquette Challenge Research Grant 

    Role: Principle Investigator

    Awarding Institution: Foundation for Physical Therapy

    Award Dates: 1/1/2014 – 12/31/2015

    Title: A Novel Unweighting Technology to Address Psychological Impairments Limiting Outcomes after ACL Reconstruction

    Aim: To determine if 8 weeks of training with the bodyweight reduction instrument to deliver graded exercise (BRIDGE) will reduce psychological impairments and restore knee loading performance in the ACLR knee more than standard jump training. Our long-term goal is to develop an effective treatment paradigm that will address the psychological factors that limit common retraining efforts designed to restore the force absorption capacity of the ACL reconstructed knee.

  4. Cardon Rehabilitation Grant

    Role: Co-Investigator (3% effort) (PI:Kinney AE)

    Awarding Institution: American Academy of Orthopaedic Manual Physical Therapists (AAOMPT)

    Title: The Relationship among Cervical Joint Mobility, Postural Sway and Cervical Spine Kinesthetic Awareness in Individuals Post-Concussion 

    Dates: 10/01/2014-10/1/2015

    Aim: The purpose of the proposed study is to examine the relationship of cervical spine joint mobility, cervical kinesthetic sense and postural sway in individuals who report being asymptomatic based on neurocognitive signs and symptoms post-concussion.
