Email: k.harman@dal.ca

Research interests: Dr. Harman's research interest is in the study of pain from prevention of chronicity to the management of chronic pain – a recurring research theme throughout her career. Her current focus of research is the use of psychological techniques to enhance patient outcomes. The impact of a positive health care provider / patient interaction, or therapeutic alliance has been clearly shown in recent clinical research findings. Dr. Harman is studying what makes up this alliance and how people on both sides of the relationship experience it. Through this better understanding, we can learn to optimize the professional relationship, leading to enhanced therapeutic benefit of the intervention being provided.

Examining Current Practice with Patients Experiencing Pain
Dr. Harman uses qualitative approaches to gather data on what treatment is provided and to examine practice patterns of rehabilitation specialises in the delivery of care to patients experiencing pain. With a focus on the development of the therapeutic alliance with patients, Dr. Harman is examining the use of psychological techniques, the establishment of rapport and the fostering of self-management skills in patients with painful conditions.
She is currently supervising two graduate students:
Peter Stilwell - Ph.D. (Health) cand.
Amy Fortin-Barrette – M.Sc (RR) cand.

Email: cheryl.kozey@dal.ca

Research interests: The Innovation in Musculoskeletal Heath and Physical activity Team (IMPACT) is multidisciplinary, including researchers from engineering, physiotherapy, kinesiology and strong clinician scientist collaborations. IMPACT is interested in promoting “Mobility for Life” through research aimed at reducing the limitations in physical function associated with the high prevalence of bone and joint disorders. Dr. Kozey is the Co-Director of the Dynamics of Human Motion laboratory with Dr. Astephen Wilson in the School of Biomedical Engineering. Dr. Kozey’s primary research interest is in understanding functional decline in those with bone and joint problems, primarily knee joint osteoarthritis and low back conditions. Her goal is to provide innovative solutions to keep people with these problems moving to maintain their joint health and subsequently overall general health through improving their physical functional. Her research is showing the importance of joint level biomechanics and specifically the role that the knee joint muscles play to maintain joint health. Indeed inappropriate joint biomechanics and muscle activity can create a negative joint environment adding to the worsening or pain and joint damage. This research is leading to identifying biomechanical targets that can form the basis for early non-surgical, non-pharmaceutical interventions.

Sample projects that graduate students have worked on include:  i) cross-sectional studies looking at how OA severity changes joint and muscle function, ii) looking at pre and post total knee arthroplasty outcomes and predicting poor outcomes, iii) examining the effects of conservative treatments such as bracing on the joint and muscles as well as on physical activity levels, iv) follow up study to determine what factors are related to increase risk of progressing to a total joint replacement surgery, v) comparing muscle activation patterns between those who do not have a low back injury to those recently recovered from a low back injury to determine who is at greater risk for re-injury, vi) determine the amount and intensity of physical activity for those with knee osteoarthritis and how does this impact pain and joint damage, vii) looking at differences in the trunk muscle activation and control in older adults and what implication that this has for increased risk of falls and viii) looking at trunk muscle control and spinal stability in those with a low back injury and the risk of re-injury.

Recurrent Low Back Injury Prediction
The goal of Dr. Cheryl Hubley-Kozey's research is to better understand recovery from a low back injury and to use this information to develop a prediction model for those who reinjure.

Physical Activity, Exercise and Special Populations

Dr. Gail Dechman

Dr. Gail Dechman
Assistant Professor

BSc (PT) (Queens), PhD (McGill)

Office: Room 430, Forrest Building

Tel: (902) 494-2734

Email: gail.dechman@dal.ca

Research interests: Dr. Dechman's research focuses on using exercise to improve function in people with chronic diseases. This includes assessing the role that aerobic and resistance exercise play in enhancing functional activity in people with chronic pulmonary disease, cancer and obesity. Dr. Dechman is also involved in developing functional outcome measures to objectively assess changes in activities of daily living for community-dwelling individuals with disabilities.

Recovery of the Ability to Perform Activities of Daily Living (ADL) Following an Acute Exacerbation of COPD
Acute exacerbations of chronic obstructive lung disease (AECOPD) result in weakness and a decline in aerobic fitness. These changes make it difficult for people to manage their daily activities. The goal of Dr. Gail Dechman's research is to use an objectively scored test of activities of daily living to help us understand the course of recovery of functional abilities following hospitalization for an AECOPD. Ultimately this research will help with the development of more effective rehabilitation programs for individuals with COPD.

Lung Function Following Weight Loss Surgery
Obesity is a complex disease that occurs as a result of interactions between genetic, biochemical, neural and psychological factors as well as environmental, social and economic influences. It is associated with many chronic conditions such as type 2 diabetes, cardiovascular disease and cancer. Dr. Gail Dechman's research involves a collaborative team from biomedical engineering, medicine and physiotherapy. The prospective study assesses lung function prior to, 5 weeks and 6 months after weight loss surgery using a sleeve gastrectomy.

Explaining Exercise Differences During and After Pulmonary Rehabilitation Using a Mixed-Methods Social Ecological Approach
Although pulmonary rehabilitation (PR) has been shown to be beneficial for both males and females, unfortunately, exercise levels in such programs are low. Furthermore, females with COPD have been shown to engage in less exercise than their male counterparts, which may be placing them at increased risk of mortality. Because of this, it is imperative that theoretical research be conducted to help explain the gender disparity in exercise during and after completing PR so that a gender-specific PR exercise interventions can be developed.
This project is a collaboration between Chris Blanchard, psychologist, Paul Hernandez, respirologist, and Gail Dechman at Dalhousie University and Ryan Rhodes (University of Victoria), John Spence (University of Alberta) and Kerry McGannon (University of Iowa).

Physiologic and Psychosocial Effects of Aerobic and Resistance Exercise in Men Undergoing Androgen Deprivation Therapy for Prostate Cancer
Androgen deprivation therapy, used to treat prostate cancer, is associated with a number of adverse effects including weight gain, muscle wasting, fatigue, hypertension, and osteoporosis. Dr. Gail Dechman's research used a prospective, randomized controlled trial design to assess whether a 16 week combined aerobic and resistance exercise program alleviates symptoms and improves quality of life for men receiving ADT.

The Validity and Reliability of the Incremental Shuttle Walk Test for Predicting VO2 in Obese Individuals
Exercise is an important part of weight loss management. However, if exercise is not prescribed properly its benefits may not be realized. Dr. Gail Dechman's study intends to assess the validity and reliability of the Incremental Shuttle Walk Test to predict directly measured VO2 (Oxycon mobile) in obese individuals by comparing test results to those from a Bruce ramp protocol treadmill test.

Comparison of NORDIC WALKING (NW) during treadmill and over-ground walking
Nordic Walking (NW)is known to increase energy expenditure compared to standard walking at the same speed. NW is also proving to be a valuable tool in rehabilitation for people with neurologic and cardiovascular diseases, as well as in weight loss management.
The purpose of Dr. Gail Dechman's study was to compare the physiologic responses of NW on a specially designed treadmill and NW on a level over-ground surface.

Development of a tool to assess the skills needed to practice evidence-based decision making (EBDM)
Dr. Gail Dechman is part of an interdisciplinary team of health professionals interested in improving the use of evidence-based decision making (EBDM) in the clinical setting. The first step in this process is to develop a tool to assess baseline skills and changes that might occur as a result of an intervention. The tool will be piloted using registered nurses, physiotherapists, and respiratory therapists across the Atlantic provinces.
