The Neck Disability Index (NDI) is a widely used questionnaire in the assessment of disability of neck patients. The aim of this study was to translate the NDI according to established guidelines into German (NDI-G) and to test the psychometric properties. Patients with acute (ACU) and chronic neck pain (CHR) and a healthy control group (HCG) completed the(More)
The aim of the present study was to determine whether force plate variables in single- and dual-task situations are able to predict the risk of multiple falls in a community-dwelling elderly population. Two hundred and seventy elderly persons (225 females, 45 males; age, 73+/-7 years) performed balance assessment with and without vision. Seven force plate(More)
BACKGROUND Additional tasks that are assumed to disturb standing postural control can be divided in added motor or added cognitive tasks. It is unknown which type of task causes the most disturbances of postural control in elderly. OBJECTIVE The aim of this study was to determine whether the dual tasking disturbance of postural control in elderly is(More)
OBJECTIVE Information about recurrence and prognostic factors is important for patients and practitioners to set realistic expectations about the chances of full recovery and to reduce patient anxiety and uncertainty. Therefore, the purpose of this study was to assess recurrence and prognostic factors for neck pain in a chiropractic patient population at 1(More)
Background: Performance of additional tasks disturbs postural control in elderly. It is unknown, however, how postural control is affected in elderly fallers and non-fallers in a reduced sensory situation. Objective: To compare differences between single and dual tasking in three test conditions; (1) no-vision, (2) under reduced somatosensory information(More)
BACKGROUND The aim of his study was to evaluate the reliability and validity of the Expanded Timed Get-up-and-Go (ETGUG) test in patients with bilateral vestibular loss (BVL). METHODS 21 BVL patients (58 ± 14 years) were recruited and measured twice by two raters. After a one hour break ETGUG was repeated by the first rater. 21 age matched controls (CON;(More)
BACKGROUND Decreased scapulothoracic motion has been associated with various pathologies of the shoulder. Reliable and simple assessment methods of scapular mobility are, however lacking. The aim of this study was to evaluate the interrater reliability of four clinical tests to assess scapulothoracic motion in patients with a slightly restricted shoulder(More)
The aim of this study was to test the reliability and validity of a preferred-standing test for measuring the risk of falling. The preferred-standing position of elderly fallers and non-fallers and healthy young adults was measured. The maximal BSW was measured. The absolute and relative reliability and discriminant validity were assessed. The expanded(More)
OBJECTIVE The aims of this observational, prospective cohort study were to: assess the patients' and therapists' perception of change after physiotherapy in an orthopedic hospital's outpatient clinic; relate these retrospective assessments to a serial assessment of pain; and study the influence of patient characteristics on the perceived change.

OBJECTIVE The Lysholm score and the Tegner activity scale are widely used for assessing knee function and activity level after knee ligament injuries. This study aimed to asses validity and reliability of the German versions of the Lysholm score (Lysholm-G) and the Tegner activity scale (Tegner-G) in patients after total knee arthroplasty (TKA).
