Regression equations based on pelvic anatomy are routinely used to estimate the hip joint centre during gait analysis. While the associated errors have been well documented, the clinical significance of these errors has not been reported. This study investigated the clinical agreement of three commonly used regression equation sets (Bell et al., Davis et al. and Orthotrak software) against the ...

OBJECTIVE The objective of this study was to examine the relation of physical performance measures with depressive symptoms in older men. METHOD A cross-sectional, multivariate comparison of several measures of upper- and lower-extremity performance and their relation with depressive symptoms was performed in 2,856 older Japanese American men, aged 71-93 years, who participated in the fourth ...

Impaired walking ability is an economically important welfare problem that affects poultry raised for meat production, including Pekin ducks. To gain a better understanding of the impacts of walking impairments on duck production, and to identify contributing variables and plausible remedies, an accurate measure of walking ability must first be defined. The viability of a 3-point gait score sys...

SECTION 1 A 73-year-old right-handed man with a history of hypertension and hyperlipidemia presented with an 18-month history of diplopia and unsteady gait. He also noted oscillating vision when turning his head to the left. The diplopia was horizontal and was worse looking at objects on his right or at a distance. Over a year, his balance worsened to the point where he required a walker due to...

SECTION 1 A 57-year-old man presented with progressive difficulty in walking for 2 weeks, resting hand tremors for 1 week, and low-volume speech for 2 days. Initially, he had difficulty in initiation of walking. Soon, he developed shortstepped gait with history of en bloc falling forward. Within 2 weeks of the onset of illness, he became bedbound. While in bed, he remained very stiff and could ...

Gait and balance impairment is highly prevalent in older people. We aimed to assess whether and how single markers of small vessel disease (SVD) or a combination thereof explain gait and balance function in the elderly. We analysed 678 community-dwelling healthy subjects from the Lothian Birth Cohort 1936 at the age of 71-74 years who had undergone comprehensive risk factor assessment, gait and...

The reduction and analysis of gait waveform data is a signi®cant barrier to the clinical application of gait analysis. Principal component modelling of gait waveform data reduced the waveform data to measures of distance from normal and these distance measures were shown to be sensitive to changes in gait pattern associated with knee osteoarthritis and its treatment by unicompartmental arthropl...

Pain associated with the injuries of hoof and surrounding tissues is an important cause of lameness. However, this condition can also be caused by non-painful changes of the locomotion system. The objective of this study was to detect the attributes of impaired gait that are associated with pain. Gait was evaluated using a subjective scoring system and objective kinematic measures, while putati...

BACKGROUND Although the hallmark feature of essential tremor (ET) is kinetic tremor, patients may exhibit additional motor features (e.g., intention tremor and mild gait ataxia) that are markers of an underlying abnormality of cerebellar function. ET is also a highly familial disorder, but we do not know whether the presence and expression of cerebellar signs are similar across family members. ...

BACKGROUND Cognitive function and physical performance are associated, but the common sequence of cognitive and physical decline remains unclear. METHODS In the Women's Health Initiative Memory Study (WHIMS) clinical trial, we examined associations at baseline and over a 6-year follow-up period between the Modified Mini-Mental State (3MS) Examination and three physical performance measures (P...
