Recipient publications.

The following are some of the articles published this year by recipients of Foundation funding:

Dina L Jones, PT, PhD, West Virginia University, a 1998 PODS II recipient, was one of the authors of the following article:

   Jones DL, Cauley JA, Kriska AM, et al.
   Physical activity and risk of revision total
   knee arthoplasty in individuals with knee
   osteoarthritis: a matched case-control study.
   J Rheumatol. 2004;31(7):1384-1390.

Jones et al concluded that physical activity does not appear to be a risk factor for revision arthroplasty and that people undergoing primary total knee arthroplasty should be encouraged to remain active after surgery.

Wendy Hurd, PT, MS, University of Delaware, a 2001 McMillan and 2004 PODS II scholarship recipient, and Terese Chmielewski, PT, PhD, SCS, University of Florida, a 2001 PODS II recipient, were among the authors of the following article, which includes data from Dr Chmielewski's Foundation-funded dissertation at the University of Delaware:

   Hurd WJ, Chmielewski TL, Axe MJ, et al.
   Differences in normal and perturbed walking
   kinematics between male and female
   athletes. Clin Biomech (Bristol, Avon).
   2004;19:465-472.

In this study, female athletes displayed altered lower-extremity movement patterns during a destabilizing walking task, as compared with male athletes. These altered walking patterns may" predispose these women to anterior cruciate ligament injuries. Alterations in hip and knee angle excursions and excursion rates may require greater muscular control to reduce ligament strain.

Margaret Finley, PT, PhD, a 2001 PODS I recipient, University of Maryland, and Mary McIntyre Rodgers, PT, PhD, a former member of the Foundation's SRC, co-authored the following article:

   Finley MA, Rodgers MM. The prevalence
   and identification of shoulder pathology in
   athletic and non-athletic wheelchair users
   with shoulder pain: a pilot study. J Rehabil
   Res Dev. 2004;41: 395-402.

Finley and Rodgers found no difference in the incidence of shoulder pain, past or present, between wheelchair-using athletes and nonathletes. No difference was found in the incidence of shoulder pain, past or present, between athletes and nonathletes. Of the 52 subjects in this study, 61.5% (32/52) reported experiencing shoulder pain, with 29% of those subjects reporting "shoulder pain at the present time." Years shine onset of disability and duration of wheelchair use was greater in those who reported shoulder pain (32/52) than in those who did not report shoulder pain (20/52). Of those subjects with shoulder pain (32/52), 44% (14/32) had clinical signs and symptoms of rotator cuff impingement and 50% (16/32) had signs of biceps tendinitis. According to these findings, involvement in athletics neither increases nor decreases the risk of shoulder pain in the population that uses manual wheelchairs.

Jennifer Stevens, PT, PhD, University of Florida, a 2000 PODS I and 2001 PODS II recipient; Ryan Mizner, University of Delaware, a 2001 McMillan doctoral scholarship and 2002 PODS I recipient; and Lynn Snyder-Mackler, PT, PhD, University of Delaware, former member of the Foundation's SRC, published the following article:

   Stevens JE, Mizner RL, Snyder-Mackler L.
   Neuromuscular electrical stimulation for
   quadriceps muscle strengthening after bilateral
   total knee arthroplasty: a case series.
   J Orthop Sports Phys Ther. 2004;34:21-29.

The purpose of this case series was to assess the effect of high-intensity neuromuscular electrical stimulation (NMES) on quadriceps muscle strength and voluntary activation following total knee arthroplasty (TKA). When NMES was added to a voluntary exercise program, deficits in quadriceps muscle strength and activation resolved quickly after TKA. Stevens was funded by PODS scholarships at the time of this study.
