Association Between Performance on an Interdisciplinary Stroke Assessment Battery and Falls in Patients With Acute Stroke in an Inpatient Rehabilitation Facility: A Retrospective Cohort Study.

Objective: To explore the association between demographic factors and functional performance measures of patients with acute stroke in an inpatient rehabilitation facility (IRF) and falls during the IRF stay and to quantify the diagnostic accuracy of functional outcome measures in identifying fallers.

Design: Retrospective cohort study.

Setting: Inpatient rehabilitation facility.

Oxygen Consumption Deficits in Patients With Residual Fatigue After Primary Coccidioidomycosis.

Patients with coccidioidomycosis often report prolonged and debilitating fatigue after other evidence of infection has resolved. In this study, we quantify fatigue, muscle weakness, and impaired aerobic capacity in 5 such individuals. A closer examination of the cardiorespiratory system may contribute to a better understanding of underlying mechanisms and potential interventions.

The association between social participation and lower extremity muscle strength, balance, and gait speed in US adults.

Social participation is associated with healthy aging, and although associations have been reported between social participation and demographics, no published studies have examined a relationship between social participation and measures amenable to intervention. The purpose was to explore the association between self-reported social participation and lower extremity strength, balance, and gait speed. A cross-sectional analysis of US adults (n = 2291; n = 1,031 males; mean ± standard deviation age 63.

Distal Vibration Perception Threshold in Children Who Toe Walk.

Purpose: To compare distal vibratory perception threshold and sensation in children who toe walked (TW) and controls.

Methods: Vibration perception threshold was measured at the metacarpal and metatarsal phalangeal (MCP and MTP) joints in 11 TW and 15 age-matched controls. Mean vibratory threshold (MVT) was calculated for each site; a Pearson correlation coefficient was determined for MVT at MCP and MTP joints.

Health-related fitness in children and adolescents.

Purpose: The American Physical Therapy Association Section on Pediatrics developed a task force to summarize fitness guidelines for children and adolescents. The purposes of this article were to review components, measurement methods, and consequences of physical fitness, and to summarize evidence-based activity recommendations for youth.

Summary Of Key Points: Health-related fitness is comprised of body composition, flexibility, cardiorespiratory endurance, and muscular strength and endurance.

Fuel oxidation at the walk-to-run-transition in humans.

Multiple factors (including anthropometric, kinetic, mechanical, kinematic, perceptual, and energetic factors) are likely to play a role in the walk-to-run transition in humans. The primary purpose of the present study was to consider an additional factor, the metabolic fuel source. Indirect calorimetry was used to measure fuel oxidation, and perception of effort was recorded as 10 overnight-fasted adults locomoted on a level treadmill at speeds progressing from 1.

Temporal characteristics of lower extremity moment generation in children with cerebral palsy.

Lower extremity weakness has been documented in children with cerebral palsy (CP). However, the temporal characteristics of moment generation have not been characterized, and they may be important to function. This study tested ankle, knee, and hip flexion and extension moment generation capabilities in children with CP and in able-bodied children.

A comprehensive joint replacement program for total knee arthroplasty: a descriptive study.

Background: Total knee arthroplasty (TKA) is a commonly performed surgical procedure in the US. It is important to have a comprehensive inpatient TKA program which maximizes outcomes while minimizing adverse events. The purpose of this study was to describe a TKA program - the Joint Replacement Program (JRP) - and report post-surgical outcomes.

Muscle metabolism during overground walking in persons with poststroke hemiparesis.

Purpose: Muscle energy metabolism is associated with speed, endurance, and effort during walking, yet data regarding muscle metabolism during walking in persons with poststroke hemiparesis have not been published. The primary purpose of this study was to compare the energy metabolism during overground walking in persons with poststroke hemiparesis to controls. The secondary purpose was to determine whether the walking behavior of persons with poststroke hemiparesis conforms to the fuel selection patterns previously observed in controls.

Intersegmental dynamics during the swing phase of gait: a comparison of knee kinetics between 7 year-old children and adults.

Existing literature suggests that kinetic patterns associated with children's gait may not be adult-like until after 7 years of age. The development of adult-like kinetic patterns, especially those involving non-muscular interaction moments, occurs with time and experience. We tested the hypothesis that compared to adults, 7 year-old children would demonstrate a relatively larger contribution of muscle moment and a smaller contribution of interaction moment to the net knee joint moment during the swing phase of gait was tested.

Fuel oxidation during human walking.

Human adults walk at a characteristic speed, but the mechanisms responsible for this ubiquitous and reproducible behavior remain unknown. In this study, preferred walking speed (PWS) was 4.7 +/- 0.

Gait kinematics and kinetics of 7-year-old children: a comparison to adults using age-specific anthropometric data.

The purpose of this study was to determine if sagittal plane gait kinematics and kinetics of 7-year-old children differed from those of adults when age-specific anthropometrics were used in the calculations. Joint angles, moments, and power obtained during level walking in 7-year-old children (n=15) were compared to data from adults (n=15). Calculations were performed using age-specific anthropometric data obtained from dual energy X-ray absorptiometry.

Anthropometric parameters in children: a comparison of values obtained from dual energy x-ray absorptiometry and cadaver-based estimates.

Anthropometric data used in gait analysis for children are often estimated from older adult cadavers. The extent to which these estimates accurately represent children or affect the calculation of net joint moments during gait analysis is unknown. The purpose of this study was: (1) to compare dual energy X-ray absorptiometry (DXA)-derived anthropometric parameters to cadaver-based estimates in children, and (2) to determine if DXA-derived anthropometric data alter the results of gait analyses in children.

Determination of lower extremity anthropometric parameters using dual energy X-ray absorptiometry: the influence on net joint moments during gait.

Objective: The purpose of this study was threefold: (1) to report on a method of determining lower extremity anthropometric data using dual energy X-ray absorptiometry, (2) to compare values obtained with this method to predictions from cadaver-based estimates, and (3) to quantify the extent to which these data affect the calculation of net joint moments during walking.

Background: Anthropometric data used in inverse dynamics equations are often estimated from older cadaveric specimens. A practical method for determining population-specific data is needed.
