OBJECTIVE to investigate the relationship between fear-related avoidance of activities and physical frailty. SUBJECTS AND METHODS fear-related avoidance of activities, physical performance, maximal isometric muscle strength and postural control were assessed in 225 community-living elderly (94 men and 131 women), aged between 61 and 92 years of age.

Many variables have retrospectively been associated with the presence of anterior knee pain. Very few prospective data exist, however, to determine which of these variables will lead to the development of anterior knee pain. It was our purpose in this study to determine the intrinsic risk factors for the development of anterior knee pain in an athletic(More)
BACKGROUND Muscular tightness is frequently postulated as an intrinsic risk factor for the development of a muscle injury. However, very little prospective data exist to prove this. HYPOTHESIS Increased muscle tightness identifies a soccer player at risk for a subsequent musculoskeletal lesion. STUDY DESIGN Prospective cohort study. METHODS We(More)
Increasing documentation on the size and appearance of muscles in the lumbar spine of low back pain (LBP) patients is available in the literature. However, a comparative study between unoperated chronic low back pain (CLBP) patients and matched (age, gender, physical activity, height and weight) healthy controls with regard to muscle cross-sectional area(More)
BACKGROUND Today, no clinical studies have been undertaken to examine the long-term effects of an open kinetic chain or closed kinetic chain program. HYPOTHESIS The long-term follow-up results after a conservative exercise protocol are significantly worse than the short-term results. The long-term effect of closed kinetic chain training is significantly(More)
Little scientific support is available concerning usual and unusual reactions after spinal manipulation although such reactions are very common in clinical practice. Fifty-nine manipulative therapists were requested to enroll 15 consecutive patients attending for their first visit to receive spinal manipulation. These patients were asked to complete a(More)
Retrospective studies have suggested various factors that might cause a disposition to develop patellar tendinitis, but no prospective data exist to determine any relationships. The purpose of this study was to determine the intrinsic risk factors for the development of patellar tendinitis in an athletic population. Before the study, 138 male and female(More)
BACKGROUND AND OBJECTIVE The chronic metabolic disorder diabetes mellitus is an important cause of morbidity and mortality due to a series of common secondary metabolic complications, such as the development of severe, often slow healing skin lesions. In view of promoting the wound-healing process in diabetic patients, this preliminary in vitro study(More)
STUDY DESIGN An experimental study of muscle recruitment patterns during asymmetric lifting in healthy individuals. OBJECTIVE To investigate muscle recruitment patterns during asymmetric lifting, representing a common daily living activity, to determine whether systematic differences exist between functioning of the local and global muscle systems.

The purpose of this study was to determine the effect of different training schedules on the cross-sectional area (CSA) of the paravertebral muscles (PA) in chronic low back pain (CLBP) patients. To achieve this goal 59 patients were randomly assigned to three different 10-week rehabilitation programs: stabilization training (group 1, n=19), stabilization(More)
