Pressure Distribution Over The Palm Region During Forward Falls On The Outstretched Hands, Woochol J. Choi, Stephen N. Robinovitch

Physical Therapy Faculty Articles and Research

Falls on the outstretched hands are the cause of over 90% of wrist fractures, yet little is known about bone loading during this event. We tested how the magnitude and distribution of pressure over the palm region during a forward fall is affected by foam padding (simulating a glove) and arm configuration, and by the faller’s body mass index (BMI) and thickness of soft tissues over the palm region.

Thirteen young women with high (n=7) or low (n=6) BMI participated in a “torso release experiment” that simulated falling on both outstretched hands with the arm inclined either at 20° or …

Performance Of A Hip Protector Depends On Its Position During A Fall, Woochol J. Choi, Joaquin A. Hoffer, Stephen N. Robinovitch

Physical Therapy Faculty Articles and Research

"Hip protectors are designed to attenuate and redistribute the force applied to the hip region during a fall, and thereby reduce risk for hip fracture [1]. However, little information exists on the effectiveness of hip protectors in achieving these goals, and how this is altered by displacement of the hip protector relative to the greater trochanter (GT). In the current study, we tested these issues."

Falling Is Not Just For Older Women: Support For Pre-Emptive Prevention Intervention Before 60, Jennifer Nitz, Nancy Low Choy

Nancy Low Choy

Objective
This study aimed to report falls and identify factors that might predict a fall in women aged between 40 and 80 years and thus provide evidence of earlier falls and need for morbidity preventive intervention.

Design and participants
A prospective cohort study design over 5 years. Personal demographic data of age, co-morbidities, number of prescribed medications, falls, activity level and living situation were obtained at face-to-face interview. Height, weight, body mass index and postural stability were measured in participating women living independently in the community.

Results
Women were categorized into age decade cohorts, with 463 remaining at the year …

Changes In Activity Level In Women Age 40 To 80 Years, Jennifer Nitz, Nancy Low Choy

Nancy Low Choy

Objectives
The purpose of this study was to report habitual physical activity levels in women and document the change in level of activity and factors affecting this change over a 5-year period.

Methods
A 5-year prospective cohort design was used. Women aged 40-80 years, living independently in the community, were recruited via the electoral role. The effects were investigated, first, of age, activity level, history of falls, number of co-morbidities and medications, body mass index and stability at baseline on change in activity level and, second, change in these demographics on activity level over the study period.

Results
Data from …

The Effect Of Depression On Balance Decline In Mature Women, Jennifer Nitz, Nancy Low Choy, Meredith Ogilvie

Nancy Low Choy

Depression has been identified as a risk factor for falls, and a change in balance ability over time has yet to be investigated. This study aimed to identify if, over a 3-year period, balance ability changed in 26 women who were on medication for depression, compared to 26 non-depressed women. The two groups were matched for age, number of co-morbidities, activity level, medications, and height. All participants were simultaneously enrolled in a larger, longitudinal study of ageing. Balance measures included the Functional Reach (FR) test, Lateral Reach (LR) test, Step Test (ST), Timed Up and Go, and the Modified Clinical …

The Efficacy Of A Balance Strategy Training Circuit For Community Based Elders Who Have Had A Fall, Jennifer Nitz, Nancy Low Choy

Nancy Low Choy

Background:
Older people participate in exercise programmes to reduce the risk of falls but no study has investigated a specific balance strategy training intervention presented in a workstation format for small groups.

Objective:
To determine whether a specific balance strategy training programmeme delivered in a workstation format was superior to a community based exercise class programme for reducing falls.

Design:
A randomised controlled trial model.

Setting:
Neurological Disorders, Ageing and Balance Clinic, Department of Physiotherapy, The University of Queensland.

Subjects:
73 males and females over 60 years, living independently in the community and who had fallen in the previous year …

Whole Body Momentum During Gait: A Preliminary Study Of Non-Fallers And Frequent Fallers, Guy G. Simoneau, David E. Krebs

Physical Therapy Faculty Research and Publications

The importance of momentum in compensating for elderly individua ls ' strength deficits to achieve activities of daily living. such as rising from a chair ha.!o been demonstrated in earlier studies. Here we present a case control study of three healthy "non-fallers" and two "frequent fallers," All 5 elders were community-living and were tested in the gai l laboratory. A four-camera Selspot system was used to obtain whole-body momentum from an 11-segment kinematic model. Ground reaction forces and kinematics were used 10 calculate lower extremity join! moments. With the exception of the whole-body's angular momentum about the vertical axis, linear …
