17Β-Estradiol Induced Effects On Anterior Cruciate Ligament Laxness And Neuromuscular Activation Patterns In Female Runners, Iman Akef Khowailed, Jerrold S. Petrofsky, Everett Lohman, Noha Daher, Mohamed Olfat

College of Health & Human Services (TUN) Publications and Research

Background: To investigate the effects of 17β-Estradiol across phases of menstrual cycle on the laxness of the anterior cruciate ligament (ACL) and the neuromuscular control around the knee joint in female runners.

Methods: Twelve healthy female runners, who reported normal menstrual cycles for the previous 6 months were tested twice across one complete menstrual cycle for serum levels of 17β Estradiol (E), and knee joint laxity (KJL). Electromyographic (EMG) activity of the quadriceps and hamstrings muscles was also recorded during running on a treadmill. The changes in the EMG activity, KJL, and hormonal concentrations were recorded for each …

Effect Of Tai Chi Exercise Combined With Mental Imagery Theory In Improving Balance In A Diabetic And Elderly Population, Abdulrahman Alsubiheen, Jerrold S. Petrofsky, Noha S. Daher, Everett Lohman, Edward Balbas

College of Health & Human Services (TUN) Publications and Research

BACKGROUND: One of the effects of diabetes mellitus (DM), peripheral neuropathy, affects the sensation in the feet and can increase the chance of falling. The purpose of the study was to investigate the effect of 8 weeks of Tai Chi (TC) training combined with mental imagery (MI) on improving balance in people with diabetes and an age matched control group.
MATERIAL AND METHODS: Seventeen healthy subjects and 12 diabetic sedentary subjects ranging from 40–80 years of age were recruited. All subjects in both groups attended a Yang style of TC class using MI strategies, 2 sessions a week …

The Effect Of Bmi On Oxygen Saturation At Rest And During Mild Walking, Jerrold S. Petrofsky, Michael S. Laymon, Iman Akef Khowailed, Stacy Fisher, Andrew Mills

College of Health & Human Services (TUN) Publications and Research

Eighty one subjects were examined for the relationship between BMI, body fat, arterial oxygen saturation and arterial PO2 with the subjects at rest and after 5 minutes of walking on a treadmill ergometer at 3 mph at a 3% grade. They had BMIs between 19 and 50. All subjects were free of cardiovascular disease and had normal blood pressure making it safe for them to participate in mild exercise. They were all able to walk for at least 10 minutes without cardiovascular complications and were not taking any medications that altered the autonomic nervous system. The age was between 22 …

Six Weeks Habituation Of Simulated Barefoot Running Induces Neuromuscular Adaptations And Changes In Foot Strike Patterns In Female Runners, Iman Akef Khowailed, Jerrold S. Petrofsky, Everett Lohman, Noha Daher

College of Health & Human Services (TUN) Publications and Research

BACKGROUND: The aim of this study was to examine the effects of a 6-week training program of simulated barefoot running (SBR) on running kinetics in habitually shod (wearing shoes) female recreational runners.
MATERIAL AND METHODS: Twelve female runners age 25.7±3.4 years gradually increased running distance in Vibram FiveFingers minimal shoes over a 6-week period. The kinetic analysis of treadmill running at 10 Km/h was performed pre- and post-intervention in shod running, non-habituated SBR, and habituated SBR conditions. Spatiotemporal parameters, ground reaction force components, and electromyography (EMG) were measured in all conditions.
RESULTS: Post-intervention data indicated a significant …

The Effect Of Continuous Heat Wraps On Balance And Gait In The Elderly, Jerrold S. Petrofsky, Michael S. Laymon, Iman Akef Khowailed

College of Health & Human Services (TUN) Publications and Research

Background: In an ageing geriatric population, tremor and poor balance become more pronounced and can lead to falls. Falls are the leading cause of mortality in this population. Continuous heat wraps have been shown to increase tissue flexibility. It was the purpose of this study to examine the effects of heat on balance and gait in the elderly with impaired mobility.

Subjects: Twenty people with impaired mobility (assessed as a score of more than 4 on the “Stepping On” questionnaire) were tested with a balance platform after using ThermaCare continuous heat wraps on their legs and knees for …

Environment: Improving Access And Participation, Tricia A. Catalino, Lori E. Meyer

College of Health & Human Services (TUN) Publications and Research

In this introduction to the Division for Early Childhood (DEC) Recommended Practices, we will briefly explain what we mean by the environment and what it means for young children with disabilities and their families. This will provide a framework for conceptualizing the inter-relatedness of environmental settings and features. We will also define types of environments in which children develop and grow and outline key ideas to consider when implementing the Environment recommended practices. This chapter will use vignettes to illustrate important themes and show examples of how practitioners can best use the Environment recommended practices.

Promoting Professional Development For Physical Therapists In Early Intervention, Tricia A. Catalino, Lisa A. Chiarello, Toby Long, Priscilla Weaver

College of Health & Human Services (TUN) Publications and Research

Early intervention (EI) service providers are expected to form cohesive teams to build the capacity of a family to promote their child’s development. Given the differences in personnel preparation across disciplines of service providers, the Early Childhood Personnel Center (ECPC) is creating integrated and comprehensive professional development models for those who provide services for young children with disabilities and their families. To help guide this process it is important to identify inter-disciplinary competencies as well as the unique knowledge and skills that each discipline contributes to the development and implementation of effective intervention plans. This paper describes personnel preparation of …

Effect Of Monophasic Pulsed Current On Heel Pain And Functional Activities Caused By Plantar Fasciitis, Abdullah K. Alotaibi, Jerrold S. Petrofsky, Noha S. Daher, Everett Lohman, Michael S. Laymon, Hasan M. Syed

College of Health & Human Services (TUN) Publications and Research

Background: Plantar fasciitis (PF) is a soft tissue disorder considered to be one of the most common causes of inferior heel pain. The aim of this study was to investigate the effect of monophasic pulsed current (MPC) and MPC coupled with plantar fascia-specific stretching exercises (SE) on the treatment of PF.

Material and Methods: Forty-four participants (22 women and 22 men, with a mean age of 49 years) diagnosed with PF were randomly assigned to receive MPC (n=22) or MPC coupled with plantar fascia-specific SE (n=22). Prior to and after 4 weeks of treatment, participants underwent baseline evaluation; …

Effect Of Heat, Cold, And Pressure On The Transverse Carpal Ligament And Median Nerve: A Pilot Study, Michael S. Laymon, Jerrold S. Petrofsky, James M. Mckivigan, Haneul Lee, Jongeun Yim

College of Health & Human Services (TUN) Publications and Research

Background: This study quantified the effects of heat, cold, and pressure on the median nerve and transverse carpal ligament in subjects without carpal tunnel syndrome.

Material/Methods: Subjects were individuals ages 20–50 who had no symptoms of carpal tunnel disease. Imaging ultrasound was used to measure the clearance around the median nerve, transverse ligament elasticity, nerve conduction velocity, thickness of the carpal ligament, and area of the median nerve. Pressure was applied to the carpal ligament to assess the effects of increasing pressure on these structures. On 3 separate days, 10 subjects had ThermaCare heat or cold packs applied, …
