Background and purpose: The Short Physical Performance Battery (SPPB) is widely used for older adults since it has a high level of validity, reliability, and responsiveness in measuring function in this population. However, only a few studies of diagnostic accuracy have assessed SPPB capacity in detecting frailty and prefrailty by estimating more detailed measurement properties. Thus, the present study aimed to evaluate the SPPB's diagnostic accuracy in detecting frailty and prefrailty, in addition to identifying cut-off points for walking time and chair stand time.

Methods: This is a cross-sectional study composed of 786 community-dwelling older adults 60 years or older, in which sociodemographic and anthropometric data, frailty phenotype, and total SPPB score, as well as walking time and chair stand time, were assessed. Analysis of a receiver operating characteristic curve was performed to identify the cut-off point, sensitivity, and specificity in the total SPPB score, as well as the walking time and chair stand time for frailty and prefrailty screening. Accuracy and positive and negative predictive values were subsequently calculated.

Results and discussion: The cut-off points identified for the total SPPB score, walking time, and chair stand time were 9 points or less (accuracy of 72.6%), 5 seconds or less, and 13 seconds or less, respectively, for frailty screening and 11 points or less (accuracy of 58.7%), 4 seconds or less, and 10 seconds or less, respectively, for prefrailty screening. The walking time showed greater frailty discriminatory capacity compared with the chair stand time (effect size = 1.24 vs 0.64; sensitivity = 69% vs 59%; and specificity = 84% vs 75%).

Conclusions: The total SPPB score has good diagnostic accuracy to discriminate between nonfrail and frail older adults using a cut-off point of 9 or less, being better to identify the true negatives (older adults who are not frail). Although the SPPB's diagnostic accuracy measures for detecting prefrailty were low to moderate, this instrument can help in screening prefrail older adults from the cutoff point of 11 or less in the total SPPB score. Identification of prefrail older adults enables implementing early treatment in this target audience and can prevent their advance to frailty.

Background and purpose: Parkinson's disease (PD) is the most common neurodegenerative movement disorder. Symptom severity leads to devastating consequences such as falls, immobility, impaired quality of life, and reduced general activity. Adopting a sedentary lifestyle creates a vicious circle, as physical inactivity can negatively affect the clinical domains of PD. Despite the recognition of the disease-modifying potential of physical activity (PA), achieving adequate exercise levels can be challenging for individuals with PD. This study aimed to investigate the repercussions of exercise-based interventions to improve PA levels in persons with PD through a systematic review with meta-analysis.

Methods: A search was conducted from database inception to February 2021 across 3 databases: PubMed, Web of Science, and Scopus. Randomized controlled trials were included if they involved persons with PD, outcome measures associated with PA levels, and an exercise-based intervention. Two reviewers performed independent data extraction and methodologic quality assessment of the studies using the Downs and Black quality checklist.

Results: A total of 6 studies were included in the study (1251 persons with PD). Four intervention types were identified: balance, strength, aerobic, and multimodal exercise (combination of several types of exercise programs). The meta-analysis showed that exercise interventions have a positive effect on PA (standard mean difference = 0.50, 95% CI =-0.02, 1.00; P = .06). The risk of bias was generally low.

Conclusions: The findings support the use of exercise-based interventions (aerobic exercise, balance exercise, strength exercise, and/or multimodal exercise) to improve PA levels. However, the limited number of studies and the heterogeneity of the interventions do not allow us to draw a definitive conclusion.

Background and purpose: Due to potential health-related consequences of osteoporosis (OP), health care providers who do not order imaging, such as physical therapists, should be aware of OP screening tools that identify individuals who need medical and rehabilitation care. However, current knowledge and guidance on screening tools is limited. Therefore, we explored OP screening tools that are appropriate and feasible for physical therapy practice, and evaluated tools' effectiveness by examining their clinimetric properties.

Methods: A systematic search of the following databases was performed: PubMed, PEDro, PsycINFO, CINAHL, and Web of Science. Articles were included if the study population was 50 years and older, had a diagnosis of OP, if the screening tool was within the scope of physical therapy practice, and was compared to either a known diagnosis of OP or bone densitometry scan results. Included articles underwent multiple reviews for inclusion and exclusion, with each review round having a different randomly selected pair of reviewers. Data were extracted from included articles for participant demographics, outcome measures, cut-off values, and clinimetric properties. Results were categorized with positive and negative likelihood ratios (+LR/-LR) based on the magnitude of change in the probability of having or not having OP.

Results: +LRs ranged from 0.15 to 20.21, with the Fracture Risk Assessment Tool (FRAX) and Study of Osteoporotic Fractures (SOF) having a large shift in posttest probability. -LRs ranged from 0.03 to 1.00, with the FRAX, Male Osteoporosis Risk Estimation Scores, Osteoporosis Self-Assessment Tool (OST), and Simple Calculated Osteoporosis Risk Estimation having a large shift in posttest probability.

Conclusion: Tools with moderate-large shift for both +LR and -LR recommended for use are: (1) OST; (2) FRAX; and (3) SOF. The variability in cut-off scores and clinimetric properties based on gender, age, and race/ethnicities made it impossible to provide one specific recommendation for an OP screening tool. Future research should focus on OP risk prediction among males and racial and ethnic groups.

Background and purpose: Physical and occupational therapy practices in skilled nursing facilities (SNFs) were greatly impacted by the 2019 Medicare Patient-Driven Payment Model (PDPM). Under the PDPM, the practice of multiparticipant therapy-treating more than one patient per therapy provider per session-increased in SNFs, but it is unknown how substituting multiparticipant therapy for individualized therapy may impact patient outcomes. This cross-sectional study establishes baseline relationships between multiparticipant therapy and patient outcomes using pre-PDPM data.

Methods: We used Minimum Data Set assessments from all short-term Medicare fee-for-service SNF stays in 2018. Using generalized mixed-effects logistic regression adjusted for therapy volume and patient factors, we examined associations between the proportion of minutes of physical and occupational therapy that were received as multiparticipant sessions during the SNF stay and 2 outcomes: community discharge and functional improvement. Multiparticipant therapy minutes as a proportion of total therapy time were categorized as none, low (below the median of 5%), medium (median to <25%), and high (≥25%) to reflect the 25% multiparticipant therapy limit required by the PDPM.

Results and discussion: We included 901 544 patients with complete data for functional improvement and 912 996 for the discharge outcome. Compared with patients receiving no multiparticipant therapy, adjusted models found small positive associations between low and medium multiparticipant therapy levels and outcomes. Patients receiving low levels of multiparticipant therapy had 14% higher odds of improving in function (95% CI 1.09-1.19) and 10% higher odds of community discharge (95% CI 1.05-1.15). Patients receiving medium levels of multiparticipant therapy had 18% higher odds of functional improvement (95% CI 1.13-1.24) and 44% higher odds of community discharge (95% CI 1.34-1.55). However, associations disappeared with high levels of multiparticipant therapy.

Conclusions: Prior to the PDPM, providing up to 25% multiparticipant therapy was an efficient strategy for SNFs that may have also benefitted patients. As positive associations disappeared with high levels (≥25%) of multiparticipant therapy, it may be best to continue delivering the majority of therapy in SNFs as individualized treatment.

Background and purpose: The Agency for Healthcare Research and Quality highlights the need for sustainable linkages between clinical and community settings to enhance prevention and improve care of people with chronic conditions. The first step in promoting linkages is understanding the knowledge and use of evidence-based programs by physical therapy (PT) professionals. Therefore, the objective of this study was to describe the knowledge of and referral to evidence-based programs in the community by a convenience sample of PT professionals and to examine the characteristics of those who refer to evidence-based programs.

Methods: A cross-sectional web-based survey containing 36 questions regarding respondents' demographics and evidence-based program knowledge and referral practices was disseminated to a convenience sample of PT professionals via email, news-blasts, social media, and word of mouth.

Results and discussion: A total of 459 PT professionals completed the survey. Approximately half reported practicing for more than 20 years and 75% are members of the American Physical Therapy Association (APTA). The majority (74%) are aware of evidence-based programs; however, fewer (56%) refer to these programs. Compared with individuals who do not refer to evidence-based programs, individuals who refer are more likely to be involved in PT organizations and be an APTA Geriatrics member. Of the individuals who do not refer to evidence-based programs, 21.5% reported not knowing they existed and 33% reported not knowing where the programs are located.

Conclusions: Most survey respondents reported knowing about evidence-based programs and more than half reported being aware of the evidence-based programs available in their communities. These results indicate many PT professionals already have a knowledge of evidence-based programs to support clinic-community linkages. As survey respondents were a sample of convenience and likely do not represent all PT professionals in the United States, the results should be interpreted with caution. Additional research on a more representative sample is needed to fully understand the current utilization of evidence-based programs, which will enable us to design efforts to improve the clinic to community transition. Improving linkages between PT professionals and community resources has the potential to benefit both patients and clinicians and lessen the burden on the health care system.

Background and purpose: To determine the effects of resistance training (RT) on symptoms, function, and lower limb muscle strength in patients with knee osteoarthritis (KOA), and to determine the optimal dose-response relationships.

Data sources: We searched the PubMed, MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and ClinicalTrials.gov databases from inception to January 23, 2022.

Eligibility criteria: Randomized controlled trials that examined the effects of RT in KOA patients (mean age ≥50 years) were included.

Data synthesis: We applied Hedges' g of the random-effects model to calculate the between-subject standardized mean difference (SMDbs). A random-effects metaregression was calculated to explain the influence of key training variables on the effectiveness of RT. We used the Grading of Recommendations Assessments, Development and Evaluation (GRADE) method to appraise the certainty of evidence.

Results: A total of 46 studies with 4289 participants were included. The analysis revealed moderate effects of RT on symptoms and function (SMDbs =-0.52; 95% CI: -0.64 to -0.40), and lower limb muscle strength (SMDbs = 0.53; 95% CI: 0.42 to 0.64) in the intervention group compared with the control group. The results of the metaregression revealed that only the variable "training period" (P< .001) had significant effects on symptoms, function, and lower limb muscle strength, and the 4 to 8 weeks of training subgroup showed greater effects than other subgroups (SMDbs =-0.70, -0.91 to -0.48; SMDbs = 0.76, 0.56 to 0.96).

Conclusions: Compared with inactive treatments, RT is strongly recommended to improve symptoms, function, and muscle strength in individuals with KOA. Dose-response relationship analysis showed that 4 to 8 weeks of RT had more benefits.

Background: An analysis of practice is conducted by the American Board of Physical Therapy Specialties (ABPTS) every 10 years to revalidate, update, and revise the description of specialty practice (DSP) for each specialty. The Geriatric Specialty Council recently conducted an analysis of practice and revised its content consistent with established procedures by the ABPTS.

Purpose: The purpose of this article is threefold: first, to describe the process of the most recent practice analysis; second, to report revisions to the description of specialty practice based on the analysis of practice; and third, to identify elements of practice that define current specialist practice in geriatric physical therapy.

Methods: A 10-member committee of subject matter experts (SMEs) and a psychometric consultant developed a survey instrument addressing geriatric physical therapy specialty practice areas. The survey was initially pilot-tested and subsequently administered online to a sample of 801 board-certified geriatric clinical specialists. The consultant facilitated the consensus process to determine decision rules in selecting the final competencies describing current geriatric physical therapy specialty practice.

Results: A total of 372 respondents fully or partially completed the survey, resulting in a response rate of 46.4%. Based on a priori decision rules regarding survey data, consensus of the group of SMEs, and input from the ABPTS, the DSP for geriatric physical therapy specialty practice was revised. Revisions (elimination [-] of prior items and addition [+] of new items) were made in Section 1: Knowledge Areas (-8 and +6), in Section 2: Professional Roles, Responsibilities, and Values (-14 and +4), and Section 3: Practice Expectations (-53 and +28).

Conclusion: The revised DSP will be used as the basis for the development of the examination blueprint for the specialist examination in geriatric physical therapy and the curricula for residency programs in geriatric physical therapy.

Background and purpose: Sarcopenia is a common muscle disease among the older population, posing an increased risk for functional decline and intervention for loss of independence in daily living. Early detection of sarcopenia among older people before functional decline would be beneficial in enhancing their quality of life. The Asian Working Group for Sarcopenia (AWGS) 2019 recommends the use of 3 screening methods for community-based sarcopenia detection: calf circumference (CC), or the Strength, Assistance in walking, Rise from a chair, Climb stairs, and Falls (SARC-F) questionnaire, or the SARC-F in combination with CC (SARC-CalF) questionnaire. This study aims to compare the relative performance of these 3 methods as screening tools for sarcopenia within a community-dwelling older population.

Methods: A total number of 700 community-dwelling older adults participated in the current study. Muscle mass, muscle strength, and physical performance were measured with bioelectrical impedance analysis, handgrip strength, and gait speed, respectively. The AWGS 2019 criteria were considered the criterion standard The sensitivity/specificity, receiver operating characteristic (ROC) curve, and area under the receiver operating characteristic curve (AUROC) analyses were determined for CC, SARC-F, and SARC-CalF to determine their relative diagnostic performance.

Results: Sarcopenia was identified in 21.4% of participants according to the AWGS2019 criteria. The overall prevalence of sarcopenia was 56.6%, 14.7%, and 22.9% according to CC, SARC-F, and SARC-CalF, respectively. Calf circumference showed the highest sensitivity but lowest specificity based on AWGS 2019 as the criterion standard regardless of age, gender, and body mass index. The SARC-CalF showed better sensitivity but similar specificity than the SARC-F. The AUROC of CC was significantly better than that of SARC-F and SARC-CalF. The AUROCs of CC, SARC-F, and SARC-CalF were statistically significant in all populations, as well as in the categories of age, gender, and body mass index ( P < .05).

Conclusions: Calf circumference is useful in ruling out the presence of sarcopenia while the SARC-F is more effective in ruling in sarcopenia, especially in the context of population-based screening. Future studies should be carried out to investigate the value of population-based sarcopenia detection using these screening tools.

Background and purpose: The literature has associated bone mineral density (BMD) and Alzheimer's disease (AD). The aim of the present systematic review was to investigate BMD in older adults with AD compared with older adults with no dementia.

Methods: Searches were performed in the MEDLINE, EMBASE, CINAHL, and Web of Science databases from inception to May 2022. Observational studies that compared BMD in the populations of interest were included. Methodical quality (risk of bias) was appraised using the Newcastle-Ottawa Scale. Quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach. Standardized mean differences (SMD) were calculated for meta-analyses.

Results and discussion: Five studies were included, involving a total of 1772 older adults (373 with AD and 1399 with no dementia). A first meta-analysis compared 207 older adults with AD and 1243 with no dementia for BMD in the femoral neck. The results showed lower BMD in the AD groups (SMD =-1.52; 95% CI, -2.61 to -0.42; P = .007, low quality of evidence). A second meta-analysis considering different sites of the body (whole body, trunk, femur, and lumbar spine) also showed lower BMD in older adults with AD compared with the group with no dementia (SMD =-0.98; 95% CI, -1.91 to -0.05; P = .04, low quality of evidence). Newcastle-Ottawa Scale scores ranged from 7 to 9, indicating low risk of bias.

Conclusions: Bone mineral density is lower in older adults with AD than in older adults with no dementia, especially in the femoral neck. These results suggest that older adults with AD may be at greater risk of developing osteopenia and osteoporosis. Current clinical practice guidelines should be amended for screening frequency and methodology for this particular cohort. Further studies are needed to confirm whether older people with AD have lower BMD in other sites of the body.
