My interest in improving health for older adults has resulted in broad clinical experience and a diverse research history.  This has exposed me to many clinical subjects in many settings, and to many vexing ethical and regulatory issues.  My early research experiences ranged from my own molecular investigations of the etiology of obesity and diabetes to Lifestyle Activity weight loss interventions in middle aged, functionally fit individuals.  These efforts taught me, amongst other things, that obesity, weight loss and body composition do impact function but are far more complicated to study well than they may first appear.  Recent work in rehabilitation, strength training and fall prevention in older adults continues to challenge me to examine how best to balance risk vs. benefit on multiple levels --for individual participants, for the specific study, and for research enterprise more broadly.  Often a risk that a patient and I may deem worthwhile for the hope of clinical benefit is simply not appropriate for a research setting; this can be difficult to understand for volunteers who are turned away, and for young investigators struggling to recruit.  More difficult for senior research colleagues and regulators is that often the “high risk subject” will indeed have adverse outcomes while enrolled in research, but that the research itself may have minimally impacted the specific outcome much less the overall risk for the individual (a particularly relevant consideration for exercise interventions and for risk of falls). 

My main hope for aging research at UM-SOM and BVAMC is that we learn to blend well the compassion that drives our clinical practices and underlies our quest for better treatment options with scientific rigor and due appreciation of the safety and regulatory requirements alluded to above.  Learning to do good research and safe, ethical research should always go hand in hand.

Intervention to Enhance Lateral Balance Function and Prevent Falls in Aging
The specific aims are to conduct a randomized, controlled trial with four training arms that will compare the effects and durability of 12 weeks of training in community living older adults at risk for falls by determining: 1) the effect of (a) waist-pull induced step training, (b) hip AB-AD muscle strengthening, and (c) a combined program compared to (d) a flexibility and relaxation program (control) on the protective stepping response to an external balance perturbation.

Community Ambulation Following Hip Fracture
This randomized controlled multi-center study will evaluate the effect of two different 4 month, home delivered multi-component Physical Therapy interventions on the ability to ambulate independently in the community among older men and women who have sustained a hip fracture.  The project also will investigate precursors to community ambulation and the cost effectiveness of delivering the program to frail and disabled older people.

Effects of Multi-Modal Exercise Intervention Post Hip Fracture
The goal of this study is to evaluate some of the key mechanisms on the pathway to changes in community ambulation in response to a Multi-Modal Intervention delivered to this frail and disabled group of older persons. This is being done as an ancillary study to a Phase III randomized clinical trial (1R01AG035009).  Hip fracture patients undergoing PT interventions will have detailed characterization of body composition, physical function and neuropsychologic ability.

Protective Balance and Startle Responses to Sudden Drop Perturbations in Aging
This project aims to begin the elucidation of the contribution of startle to the impaired reaction of older adults to balance perturbation.

Department of Veterans Affairs (PI Leslie Katzel)

The GRECC conducts research, clinical, and educational programs for older veterans with chronic disease and other risk factors for disability and death.  Increasingly, investigations on rehabilitation are being supplemented with preventive exercise and lifestyle interventions to test whether health and independence of older adults can be preserved longer and more cost effectively.

Claude D. Pepper Older American Independence Center
The aims of the UM-OAIC are to: 1) conduct research that examines the mechanisms underlying the functional impairments associated with stroke, hip fracture, and prevalent chronic diseases in older people; 2) design novel, exercise and activity-based rehabilitation interventions that produce clinically relevant outcomes and study the mechanisms underlying them; 3) translate interventions developed in UM-OAIC clinical laboratories and in other clinical centers for implementation and rigorous evaluation in community settings; 4) support pilot and exploratory studies, development projects, and externally-funded projects that support the UM-OAIC mission; and 5) to foster the career development of junior faculty/scholars into independent, academic scientists with expertise in the study of older persons with disabling diseases through mentor-based, bench-to-bedside translational research training that includes didactic and experiential/practical-applied training in conducting independent, aging research.
