Step Test Evaluation of Performance on Stairs (STEPS): Assessing Stair Function in Older Adults

BACKGROUND AND PURPOSE

Stair negotiation is crucial for functional independence and is a leading cause of fall-related injuries in older adults. The Step Test Evaluation of Performance on Stairs (STEPS) is a quick and easily administered outcome measure for assessing stair negotiation. This study investigated the reliability and concurrent content validity of the STEPS test to determine its usefulness in older adults.

METHODS

Eighty-two community-dwelling older adults (mean age 81.2 years, 51 females) were assessed on the STEPS test, Timed Up and Go (TUG), 5-times sit to stand (5XSTS), stair self-efficacy (SSE) questionnaire, and time to ascend and descend stairs. Participants repeated the STEPS test 7 to 14 days later for intrarater reliability by the same rater. Spearman rank and intraclass correlations were used to determine the association of measures and intrarater reliability.

RESULTS AND DISCUSSION

The mean STEPS score was 15.6 (SD = 3.7) out of 20. The STEPS total score demonstrated excellent intra- and interrater reliability. It had moderate to good and significant correlations with TUG, 5XSTS, SSE, and time to ascend and descend measures. Faster performance on the 5XSTS, TUG, and time to ascend and descend correlated with better performance on the STEPS test, indicating validity for assessing balance and mobility during stair negotiation in older adults. Lower SSE correlated with lower observer ratings of performance on stairs (STEPS scores), indicating agreement between participant reports of self-efficacy and observer ratings of performance. Step Test Evaluation of Performance on Stairs items that demonstrated the most frequent loss of points were balance (use of handrail), step continuity, foot placement, and self-propulsion (ascent only).

CONCLUSIONS

Assessment of older adults' safety and performance on stairs is vital given the increased difficulty of stair navigation and the high risk for injurious falls in this population. This study demonstrates that the STEPS test is a reliable and valid outcome measure for assessing stair performance in older adults.

Coordination of Care Among Physical Therapists and Neurologists in Huntington Disease

This paper presents a framework for physical therapy through the course of Huntington’s disease (HD) which includes coordinated care plans with neurologists. HD is an inherited neurodegenerative disorder that leads to impaired strength and coordination and ultimately progressive loss of function. Interdisciplinary HD care teams provide patient-centered, comprehensive evaluations and make recommendations for pharmacological, healthcare and lifestyle interventions based on best available evidence. Physical therapists work to improve movement and mobility using specific therapeutic interventions and individualized exercise programs. The proposed framework recommends that neurologists refer persons with HD to physical therapy at all disease stages, ideally beginning in premanifest and early stages, and that they regularly communicate with physical therapists to ensure implementation of a coordinated care plan. Resources are provided for neurologists to facilitate appropriate referral for individuals with HD to physical therapy based on clinical practice guidelines, including a referral decision guide.

The Feasibility of Action Observation and Repetitive-Task Practice Combined for Chronic Stroke Survivor Upper Limb Outcomes

Date Presented Accepted for AOTA INSPIRE 2021 but unable to be presented due to online event limitations.

Both action observation and repetitive-task practice are efficacious interventions for poststroke upper limb hemiplegia individually, yet these interventions have not been combined before. A feasibility study was completed to determine preliminary evidence of the response to intervention and whether a Phase III study should be completed to test efficacy of the combined intervention. The functional impact of improving poststroke upper limb performance could benefit millions of stroke survivors.

Clinical recommendations to guide physical therapy practice for Huntington disease

OBJECTIVE

In the past decade, an increasing number of studies have examined the efficacy of physical therapy interventions in people with Huntington disease (HD).

METHODS

We performed a mixed-methods systematic review using Joanna Briggs Institute (JBI) methodology and included experimental and observational study designs. The search resulted in 23 quantitative studies and 3 qualitative studies from which we extracted data using JBI standardized extraction tools. Results of this review suggested that physical therapy interventions may improve motor impairments and activity limitations in people with HD. Here, we expand on the review findings to provide specific recommendations to guide clinical practice.

RESULTS

We recommend the following specific physical therapy interventions for people with HD: aerobic exercise (grade A evidence), alone or in combination with resistance training to improve fitness and motor function, and supervised gait training (grade A evidence) to improve spatiotemporal features of gait. In addition, there is weak (grade B) evidence that exercise training improves balance but does not show a reduction in the frequency of falls; inspiratory and expiratory training improves breathing function and capacity; and training of transfers, getting up from the floor, and providing strategies to caregivers for involvement in physical activity in the midstages of HD may improve performance. There is expert consensus for the use of positioning devices, seating adaptations, and caregiver training in late stages of HD.

CONCLUSIONS

There is strong evidence to support physical therapy interventions to improve fitness, motor function, and gait in persons with HD.

Physical Therapy and Exercise Interventions in Huntington's Disease: A Mixed Methods Systematic Review

Background:

A number of studies evaluating physical therapy and exercise interventions in Huntington’s disease have been conducted over the past 15 years. However, an assessment of the quality and strength of the evidence in support of these interventions is lacking.

Objective:

The purpose of this systematic review was to investigate the effectiveness of physical therapy and exercise interventions in people with Huntington’s disease, and to examine the perceptions of patients, families and caregivers of these interventions.

Methods:

This mixed-methods systematic review utilized the Joanna Briggs Institute (JBI) approach and extraction tools to evaluate the literature from January 2003 until May 2016. The review considered interventions that included exercise and physical therapy interventions, and included both quantitative and qualitative outcome measures.

Results:

Twenty (20) studies met the inclusion criteria, including eighteen (18) that had quantitative outcome measures and two (2) that utilized qualitative methods. JBI Levels of evidence for the 18 quantitative studies were as follows: Eight studies were at evidence Level 1, seven were at Level 2, two were at Level 3, and one was at Level 4.

Conclusions:

Our review suggests that there is preliminary support for the benefits of exercise and physical activity in Huntington’s disease in terms of motor function, gait speed, and balance, as well as a range of physical and social benefits identified through patient-reported outcomes. Variability in mode of intervention as well as outcome measures limits the interpretability of these studies, and high-quality studies that incorporate adaptive trial designs for this rare disease are needed.

Acute myeloid leukemia derived from lympho-myeloid clonal hematopoiesis

We studied acute myeloid leukemia (AML) patients with lympho-myeloid clonal hematopoiesis (LM-CH), defined by the presence of DNA methyltransferase 3A (DNMT3A) mutations in both the myeloid and lymphoid T-cell compartment. Diagnostic, complete remission (CR) and relapse samples were sequenced for 34 leukemia-related genes in 171 DNMT3A mutated adult AML patients. AML with LM-CH was found in 40 patients (23%) and was associated with clonal hematopoiesis of indeterminate potential years before AML, older age, secondary AML and more frequent MDS-type co-mutations (TET2, RUNX1 and EZH2). In 82% of AML patients with LM-CH, the preleukemic clone was refractory to chemotherapy and was the founding clone for relapse. Both LM-CH and non-LM-CH MRD-positive AML patients who achieved CR had a high risk of relapse after 10 years (75% and 75%, respectively) compared with patients without clonal hematopoiesis in CR with negative MRD (27% relapse rate). Long-term survival of patients with LM-CH was only seen after allogeneic hematopoietic stem cell transplantation (HSCT). We define AML patients with LM-CH as a distinct high-risk group of AML patients that can be identified at diagnosis through mutation analysis in T cells and should be considered for HSCT.

Are triage questions sufficient to assign fall risk precautions in the ED?

OBJECTIVES

The American College of Emergency Physicians Geriatric Emergency Department (ED) Guidelines and the Center for Disease Control recommend that older adults be assessed for risk of falls. The standard ED assessment is a verbal query of fall risk factors, which may be inadequate. We hypothesized that the addition of a functional balance test endorsed by the Center for Disease Control Stop Elderly Accidents, Deaths, and Injuries Falls Prevention Guidelines, the 4-Stage Balance Test (4SBT), would improve the detection of patients at risk for falls.

METHODS

Prospective pilot study of a convenience sample of ambulatory adults 65 years and older in the ED. All participants received the standard nursing triage fall risk assessment. After patients were stabilized in their ED room, the 4SBT was administered.

RESULTS

The 58 participants had an average age of 74.1 years (range, 65-94), 40.0% were women, and 98% were community dwelling. Five (8.6%) presented to the ED for a fall-related chief complaint. The nursing triage screen identified 39.7% (n=23) as at risk for falls, whereas the 4SBT identified 43% (n=25). Combining triage questions with the 4SBT identified 60.3% (n=35) as at high risk for falls, as compared with 39.7% (n=23) with triage questions alone (P<.01). Ten (17%) of the patients at high risk by 4SBT and missed by triage questions were inpatients unaware that they were at risk for falls (new diagnoses).

CONCLUSIONS

Incorporating a quick functional test of balance into the ED assessment for fall risk is feasible and significantly increases the detection of older adults at risk for falls.

Helping hands for healthy living: a collaborative service learning project with occupational and physical therapy students

The purpose of this article is to describe the development of a unique interdisciplinary service-learning course and to evaluate the impact of this experience on allied health students' professional development. One hundred and twenty-seven students from occupational and physical therapy programs served medically uninsured individuals (n = 170) at a community health clinic through provision of direct patient care services, depression screens, and a health promotion program. Surveys and personal reflections were used to measure the outcome of the course. The results indicated that student cognitive skills, ability to work with diverse populations, social responsibility, beliefs and opinions about service learning, and appreciation of each other's discipline were enhanced by their participation in the class.

Development, analysis, refinement, and utility of an interdisciplinary amyotrophic lateral sclerosis database

The current status of evaluation and management provided by individual healthcare professionals (HCP) at amyotrophic lateral sclerosis (ALS) centers and clinics needs to be analyzed. This paper describes one ALS center's experiences with the development, analysis, refinement, and utility of an interdisciplinary, HCP-driven ALS database. The purpose and conceptual framework of the database, the general data that needed to be collected, and the types of reports that needed to be generated were determined, and, in collaboration with a computer programmer, data entry and database management systems were developed. Data were collected on 234 patients between September 1996 and August 1998, and were analyzed by a biostatistician. Based on review of the biostatistician's report and discussion of problems encountered with the systems, the database was then refined. Benefits of the database system included: systematization of data collection and reporting, reduction of redundant data collection by individuals, decreased variability of evaluation methods and management decisions from patient to patient, and increased availability of a variety of uniform patient information to assist team members in making care decisions. Ongoing refinement will ensure that this HCP-driven ALS database continues to be informative, practical and effective for decision-making and enhancing delivery of care.
