“…4 Older adults with self-reported physical limitation had a CS-PFP score of 23.6 Ϯ 8.6 and a SIP total score of 15.15 Ϯ 12. 4 We acknowledge limitations to this study. Our sample size was small and did not permit us to examine differences across diagnostic categories.…”

“…5 The CS-PFP, a valid and sensitive measure of physical function, has been used to characterize function in older adults with a broad range of ability. 4 The CS-PFP includes 16 everyday tasks important in independent living. The tasks are listed in Table 2 and a full description of the test is published elsewhere, 4,5 with detailed information available at www.coe.uga.edu/cspfp.…”

“…The ranges closely approximated those found in the population of older adults evaluated for the CS-PFP. 4,5 The scaled task scores within each domain were averaged to yield a domain score for the individual: upperbody strength, upper-body flexibility, balance and coordination, and endurance. A WC-PFP total score was derived from averaging all tasks.…”

“…In this paper, we address the measurement of physical aspects of functional limitation. A growing body of research demonstrates that performancebased measures of function can be used to identify the underlying domains of impairment 4 and to predict health service utilization, 13 falls, 15 institutionalization, and mortality 9 in older adults. In addition, performance-based functional measures are more sensitive to change than self-reported function, 5 and less influenced by affective disorders.…”

Study Design: Descriptive study. Objectives: To develop a performance-based physical functional measure for people using a manual wheelchair, and to evaluate the feasibility and reliability of the administration of the new procedure. Background: Most performance-based measures of physical function focus on balance and ambulation impairments. Recent developments of performance measures fail to produce a valid and reliable performance-based measure to quantify physical function in people who must rely on upper-body function to mobilize. Methods: Eighteen adults (ages 18 to 67 years) who used a nonmotorized wheelchair participated in this study. Volunteers performed selected tasks from the Continuous Scale Physical Functional Performance (CS-PFP) test, modified for persons using a wheelchair. Outcome measures included scores on the Wheelchair Physical Functional Performance (WC-PFP) test and the Sickness Impact Profile (SIP) questionnaire. Results: Participants had substantial disability (mean total SIP Ͼ 20). Total and domain scores of the WC-PFP had no ceiling or floor effects and were reproducible with intraclass correlation coefficients ranging from 0.87 to 0.96. Poorer self-rated health was correlated with poorer performance in the upper-body domain of the WC-PFP (r = Ϫ0.45). Those reporting disability in bathing and dressing using the SIP had significantly lower WC-PFP scores, indicating that the WC-PFP had construct validity. A significant correlation was not found between WC-PFP and the ambulation and mobility domains of the SIP. Conclusion: The WC-PFP provides a reliable and quantifiable measure of mobility in persons who use a manual wheelchair.

“…The test has been validated for use in older populations (5,4), and the reproducibility of the CS-PFP10 scores and subscales are very good, with intraclass correlation coefficients in the range of r = 0.79 to 0.94; and (c) the visual analog dyspnea scale (VAS) measured dyspnea. Immediately upon completion of the CS-PFP10 participants were instructed to indicate their degree of breathlessness by marking along the 10cm horizontal line.…”

Int J Exerc Sci 2(3) : 202-214, 2009. The purpose of this study was to utilize the disablement pathway model to examine the contribution of physical function, dyspnea, and pain to disability in activities-of-daily-living (ADL) in culturally diverse older adults. Participants were 51 older adults (age = 69.0 years ± 9.7; 76.5% African-American, 51.0% < high school education, 52.9% < $20,000 annual income) from an urban community center and an independent living housing facility for seniors. Participants completed the Functional Status Index (FSI), which provides ratings of need for assistance (FSIA) and pain (FSIP) with ADL, the Continuous Scale Physical Functional Performance 10-item Test (CS-PFP10), and an analog dyspnea scale. Hierarchical multiple regression analyses revealed that facility, physical function, pain, and dyspnea accounted for 50.5% of the variance in disability and that pain (β = .43, p < .01) and physical function (β = -.39, p < .01) were the only significant predictors. In the second model, facility, dyspnea, and pain explained 27.6% of the variance in physical function, and facility (β = .39, p < .01) and dyspnea (β = -.26, p = .05) were the only significant predictors. Based on the disablement pathway model, physical functional improvement and pain prevention and management should be targeted when designing culturally appropriate strategies for delaying disability and maintaining independent life.

High‐resolution tracking of motor disorders in Parkinson's disease during unconstrained activity

et al. 2013

Parkinson’s disease (PD) can present with a variety of motor disorders that fluctuate throughout the day, making assessment a challenging task. Paper-based measurement tools can be burdensome to the patient and clinician and lack the temporal resolution needed to accurately and objectively track changes in motor symptom severity throughout the day. Wearable sensor-based systems that continuously monitor PD motor disorders may help to solve this problem, although critical shortcomings persist in identifying multiple disorders at high temporal resolution during unconstrained activity. The purpose of this study was to advance the current state of the art by (1) introducing hybrid sensor technology to concurrently acquire surface electromyographic (sEMG) and accelerometer data during unconstrained activity and (2) analyzing the data using dynamic neural network algorithms to capture the evolving temporal characteristics of the sensor data and improve motor disorder recognition of tremor and dyskinesia. Algorithms were trained (n = 11 patients) and tested (n = 8 patients; n = 4 controls) to recognize tremor and dyskinesia at 1-second resolution based on sensor data features and expert annotation of video recording during 4-hour monitoring periods of unconstrained daily activity. The algorithms were able to make accurate distinctions between tremor, dyskinesia, and normal movement despite the presence of diverse voluntary activity. Motor disorder severity classifications averaged 94.9% sensitivity and 97.1% specificity based on 1 sensor per symptomatic limb. These initial findings indicate that new sensor technology and software algorithms can be effective in enhancing wearable sensor-based system performance for monitoring PD motor disorders during unconstrained activities.
