The Life-Space Assessment Measure of Functional Mobility Has Utility in Community-Based Physical Therapist Practice in the United Kingdom.

ABSTRACT:

Background

The Life-Space Assessment (LSA) has demonstrable validity and reliability among people sampled from nonclinical settings. Its properties in clinical settings, especially physical therapy services, are less well established.

Objective

The aim of this study was to test the construct/convergent validity, responsiveness, and floor/ceiling effects of the LSA among patients who had musculoskeletal, orthopedic, neurological, or general surgical presentations and were receiving individually tailored, community-based physical therapist interventions to address gait/balance impairments in an urban location in the United Kingdom.

Design

A prospective, repeated-measures, comparative cohort design was used.

Methods

Two hundred seventy-six community-dwelling, newly referred patients were recruited from three cohorts (outpatients; domiciliary, nonhospitalized; and domiciliary, recent hospital discharge). Data were collected from the LSA and the Performance-Oriented Mobility Assessment (POMA1) at initial assessment and discharge. Two hundred twenty-eight participants were retained at follow-up.

Results

The median age was 80.5 years, 73.6% were women, and the median number of physical therapist contacts over 53 days was five. LSA scores at assessment and changes over treatment distinguished between cohorts, even after adjustment for covariates. Weak correlations (0.14-0.41) were found between LSA and POMA1 scores. No LSA floor/ceiling effects were found. Significant improvements in the LSA score after the intervention were found for each cohort and for the sample overall. For the whole sample, the mean change in the LSA score was 10.5 points (95% CI = 8.3-12.8).

Limitations

The environmental demands participants faced were not measured. Caregivers answered the LSA questions on behalf of participants when necessary. Assessors were not always masked with regard to the measurement point.

Conclusions

The LSA has utility as an outcome measure in routine community-based physical therapist practice. It has satisfactory construct validity and is sensitive to change over a short time frame. The LSA is not a substitute for the POMA1; these measures complement each other, with the LSA bringing the added value of measuring real-life functional mobility.

Project description:BackgroundThis study describes osteopathic practise activity, scope of practice and the osteopathic patient profile in order to understand the role osteopathy plays within the United Kingdom's (UK) health system a decade after our previous survey.MethodWe used a retrospective questionnaire survey design to ask about osteopathic practice and audit patient case notes. All UK registered osteopaths were invited to participate in the survey. The survey was conducted using a web-based system. Each participating osteopath was asked about themselves, their practice and asked to randomly select and extract data from up to 8 random new patient health records during 2018. All patient related data were anonymised.ResultsThe survey response rate was 500 osteopaths (9.4% of the profession) who provided information about 395 patients and 2,215 consultations. Most osteopaths were self-employed (81.1%; 344/424 responses) working alone either exclusively or often (63.9%; 237/371) and were able to offer 48.6% of patients an appointment within 3 days (184/379). Patient ages ranged from 1 month to 96 years (mean 44.7 years, Std Dev. 21.5), of these 58.4% (227/389) were female. Infants <1 years old represented 4.8% (18/379) of patients. The majority of patients presented with musculoskeletal complaints (81.0%; 306/378). Persistent complaints (present for more than 12 weeks before appointment) were the most common (67.9%; 256/377) and 41.7% (156/374) of patients had co-existing medical conditions. The most common treatment approaches used at the first appointment were soft-tissue techniques (73.9%; 292/395), articulatory techniques (69.4%; 274/395) and high velocity low amplitude thrust (34.4%; 136/395). The mean number of treatments per patient was 7 (mode 4).ConclusionOsteopaths predominantly provide care of musculoskeletal conditions, typically in private practice. To better understand the role of osteopathy in UK health service delivery, the profession needs to do more research with patients in order to understand their needs and their expected outcomes of care, and for this to inform osteopathic practice and education.

Project description:BackgroundEarly rehabilitation improves outcomes, and increased use of physical therapist services in the intensive care unit (ICU) has been recommended. Little is known about the implementation of early rehabilitation programs or physical therapists' preparation and perceptions of care in the United States.ObjectiveA national survey was conducted to determine the current status of physical therapist practice in the ICU.DesignThis study used a cross-sectional, observational design.MethodsSelf-report surveys were mailed to members of the Acute Care Section of the American Physical Therapy Association. Questions addressed staffing, training, barriers, and protocols, and case scenarios were used to determine perceptions about providing rehabilitation.ResultsThe response rate was 29% (667/2,320). Staffing, defined as the number of physical therapists per 100 ICU beds, was highest in community hospitals (academic: median=5.4 [range=3.6-9.2]; community: median=6.7 [range=4.4-10.0]) and in the western United States (median=7.5 [range=4.2-12.9]). Twelve percent of physical therapists reported no training. Barriers to providing ICU rehabilitation included insufficient staffing and training, departmental prioritization policies, and inadequate consultation criteria. Responses to case scenarios demonstrated differences in the likelihood of consultation and physical therapists' prescribed frequency and intensity of care based on medical interventions rather than characteristics of patients. Physical therapists in academic hospitals were more likely to be involved in the care of patients in each scenario and were more likely to perform higher-intensity mobilization.LimitationsMembers of the Acute Care Section of the American Physical Therapy Association may not represent most practicing physical therapists, and the 29% return rate may have contributed to response bias.ConclusionsAlthough staffing was higher in community hospitals, therapists in academic and community hospitals cited insufficient staffing as the most common barrier to providing rehabilitation in the ICU. Implementing strategies to overcome barriers identified in this study may improve the delivery of ICU rehabilitation services.
