Rehabilitation Sciences Faculty Publications

Context: Altered neuromuscular control strategies during fatigue probably contribute to the increased incidence of non-contact anterior cruciate ligament injuries in female athletes.

Objective: To determine biomechanical differences between 2 fatigue protocols (slow linear oxidative fatigue protocol [SLO-FP] and functional agility short-term fatigue protocol [FAST-FP]) when performing a running-stop-jump task.

Design: Controlled laboratory study.

Setting: Laboratory.

Patients or Other Participants: A convenience sample of 15 female soccer players (age = 19.2 ± 0.8 years, height = 1.67± 0.05m, mass = 61.7 + 8.1 kg) without injury participated.

Intervention(s): Five successful trials of a running–stop-jump task were obtained prefatigue and postfatigue during …

Falls And Physical Activity In Persons With Multiple Sclerosis, J. J. Sosnoff, B. M. Sandroff, J. H. Pula, S. M. Morrison, R. W. Motl

Rehabilitation Sciences Faculty Publications

Objectives. To examine the association between fall history and physical activity using an objective measure of physical activity (i.e., accelerometry) in persons with multiple sclerosis.

Design. A community-based sample of 75 ambulatory persons with multiple sclerosis volunteered for the investigation. Participants self-reported fall history in the last year, underwent a neurological exam to determine Expanded Disability Status Scale (EDSS) score, and wore an accelerometer around the waist for 7 consecutive days to determine physical activity.

Results. Overall, 37 persons (49.3% of the sample) reported falling in the last year with 28 of the 37 falling more than once. Persons who …

Aging, Neuromuscular Decline, And The Change In Physiological And Behavioral Complexity Of Upper-Limb Movement Dynamics, S. Morrison, K. M. Newell

Rehabilitation Sciences Faculty Publications

Aging is characterized by a general decline in physiological and behavioral function that has been widely interpreted within the context of the loss of complexity hypothesis. In this paper, we examine the relation between aging, neuromuscular function and physiological-behavioral complexity in the arm-hand effector system, specifically with reference to physiological tremor and isometric force production. Experimental findings reveal that the adaptive behavioral consequences of the aging-related functional decline in neurophysiological processes are less pronounced in simple motor tasks which provides support for the proposition that the motor output is influenced by both extrinsic (e.g., task related) and intrinsic (e.g., coordination, …

Approved Clinical Instructors' Perspectives On Implementation Strategies In Evidence-Based Practices For Athletic Training Students, Dorice A. Hankemeier, Bonnie L. Van Lunen

Rehabilitation Sciences Faculty Publications

Context: Understanding implementation strategies of Approved Clinibal Instructors (ACIs) who use evidence-based practice (EBP) in clinical instruction will help promote the use of EBP in clinical practice.

Objective: To examine the perspectives and experiences of ACIs using EBP concepts in undergraduate athletic training education programs to determine the importance of using these concepts in clinical practice, clinical EBP implementation strategies for students, and challenges of implementing EBP into clinical practice while mentoring and teaching their students.

Design: Qualitative study.

Setting: Telephone interviews.

Patients or Other Participants: Sixteen ACIs (11 men, 5 women; experience as a certified athletic trainer = 10 …

Overcoming Barriers To Implementation Of Evidence-Based Practice Concepts In Athletic Training Education: Perceptions Of Select Educators, Sarah Manspeaker, Bonnie Van Lunen

Rehabilitation Sciences Faculty Publications

Context: The need to include evidence-based practice (EBP) concepts in entry-level athletic training education is evident as the profession transitions toward using evidence to inform clinical decision making.

Objective: To evaluate athletic training educators' experience with implementation of EBP concepts in Commission on Accreditation of Athletic Training Education (CAATE)-accredited entry-level athletic training education programs in reference to educational barriers and strategies for overcoming these barriers.

Design: Qualitative interviews of emergent design with grounded theory.

Setting: Undergraduate CAATE-accredited athletic training education programs.

Patients or Other Participants: Eleven educators (3 men, 8 women). The average number of years teaching was 14.73 ± …

Mobility, Balance, And Falls In Persons With Multiple Sclerosis, Jacob J. Sosnoff, Michael J. Socie, Morgan K. Boes, Brian M. Sandroff, John H. Pula, Yoojin Suh, Madeline Weikert, Steven Morrison, Robert W. Motl

Rehabilitation Sciences Faculty Publications

Background: There is a lack of information concerning the relation between objective measures of gait and balance and fall history in persons with MS (PwMS). This investigation assessed the relation between demographic, clinical, mobility and balance metrics and falls history in persons with multiple sclerosis (MS).

Methods: 52 ambulatory persons with MS (PwMS) participated in the investigation. All persons provided demographic information including fall history over the last 12 months. Disease status was assessed with Expanded Disability Status Scale (EDSS). Walking speed, coordination, endurance and postural control were quantified with a multidimensional mobility battery.

Results: Over 51% of the participants …

The Reliability Of Portable Fixed Dynamometry During Hip And Knee Strength Assessments, Roger O. Kollock Jr., James A. Onate, Bonnie Van Lunen

Rehabilitation Sciences Faculty Publications

Context: Insufficient lower extremity strength may be a risk factor for lower extremity injuries such as noncontact anterior cruciate ligament tears. Therefore, clinicians need reliable instruments to assess strength deficiencies.

Objective: To assess the intrarater, interrater, intrasession, and intersession reliability of a portable fixed dynamometer in measuring the strength of the hip and knee musculature.

Design: Crossover study.

Setting: Sports medicine research laboratory.

Patients or Other Participants: Three raters (A, B, C) participated in this 2-phase study. Raters A and B tested 11 healthy college graduate students (2 men, 9 women) in phase 1. Raters A and C tested 26 …

Patellofemoral Pain In Female Ballet Dancers: Correlation With Iliotibial Band Tightness And Tibial External Rotation, John Winslow, Evangeline Yoder

Rehabilitation Sciences Faculty Publications

Review of the literature reveals that ballet dancers have a high incidence of idiopathic patellofemoral pain. Twenty-four female ballet dancers were subjects in a study of the relationship between: 1) iliotibial band (ITB) tightness and patellofemoral pain, and 2) ITB tightness and degrees of tibial external rotation used in the dance demi-plie. Dancers were initially assessed by questionnaire to determine if any had knee pain. Twelve subjects mel the study criteria for patellofemoral pain, and 12 dancers without knee pain served as controls for the study. Iliotibial band tightness was measured (Ober test), and degrees of tibial external rotation used …
