Modeling Cues May Reduce Sway Following Sit-To-Stand Transfer for People with Parkinson's Disease.

Cues are commonly used to overcome the effects of motor symptoms associated with Parkinson's disease. Little is known about the impact of cues on postural sway during transfers. The objective of this study was to identify if three different types of explicit cues provided during transfers of people with Parkinson's disease results in postural sway more similar to healthy controls. This crossover study had 13 subjects in both the Parkinson's and healthy control groups. All subjects completed three trials of uncued sit to stand transfers. The Parkinson's group additionally completed three trials of sit to stand transfers in three conditions: external attentional focus of reaching to targets, external attentional focus of concurrent modeling, and explicit cue for internal attentional focus. Body worn sensors collected sway data, which was compared between groups with Mann Whitney U tests and between conditions with Friedman's Tests. Sway normalized with modeling but was unchanged in the other conditions. Losses of balance presented with reaching towards targets and cueing for an internal attentional focus. Modeling during sit to stand of people with Parkinson's disease may safely reduce sway more than other common cues.

Reliability, responsiveness, and validity of slow walking speed in community dwelling older adults.

BACKGROUND: Independent ambulation requires adaptability. Self-selected and maximum walking speeds are often both assessed to demonstrate the ability to adapt speed to different tasks and environments. However, purposefully walking at a slow speed (slowWS) could also be an appropriate adaptation in certain situations but has rarely been investigated. RESEARCH QUESTION: The purpose of this study was to assess the reliability, responsiveness, and concurrent validity of slowWS in community-dwelling older adults. METHODS: This was an observational, cross-sectional study of 110 community-dwelling older adults. Test-retest and inter-rater reliabilities of slowWS were assessed with intra-class correlation coefficients. Standard error of measurement (SEM) and minimal detectable change (MDC95) were calculated to determine responsiveness. Concurrent validity was assessed with Spearman rank-order correlations between slowWS and a battery of tests previously shown to be related to walking speed. RESULTS: Walking speed measurement for slowWS was shown to have excellent test-retest and interrater reliability (ICCs values of 0.971-0.997). Standard error of measurement value was small (0.015 m/sec) and MDC95 was 0.04 m/sec. SlowWS was not found to significantly correlate to any other study variable. SIGNIFICANCE: Walking speed, whether self-selected, maximum, or slow, can be measured reliably with a stopwatch and specific verbal commands. While slowWS could be beneficial for certain tasks or environments, walking slowly was not associated with age, sex, comorbidity, or measures of cognition, depression, strength, balance, disability, or life-space in this sample.

Volunteer Leadership in the American Physical Therapy Association: A Phenomenological Study of Early Career Physical Therapists.

OBJECTIVE: Professional associations rely on the work of volunteer leaders to serve their members. Little is known about the experiences of individuals who choose to seek and participate in these volunteer roles in the American Physical Therapy Association (APTA). The purpose of this qualitative study was to understand the lived experience of early career professionals engaged in volunteer leadership in APTA. METHODS: The study used a phenomenological design to explore the experience of volunteer leadership by novice physical therapists. Physical therapists holding a volunteer leadership position in APTA and in the first 7 years of clinical practice were recruited using purposeful sampling. One-on-one semistructured interviews were conducted. Following transcription, interviews were analyzed and coded using the constant comparison method. RESULTS: Thirteen physical therapists participated. Eleven themes emerged: (1) internal factors that facilitated volunteerism-Passion, Internal drive, Always involved, Protect and advance the profession; (2) external forces that facilitated and sustained volunteer leadership-Professional role models, Meeting the leaders, Someone asked, Support of others; and (3) behaviors that sustained their involvement-Learning while doing, Future plans, and Encouraging others' involvement. CONCLUSIONS: Novice physical therapists who volunteer for leadership roles within APTA have a passion for protecting and advancing the profession that leads to their decision to volunteer. Other members including faculty and experienced leaders in the association facilitate their initial volunteerism and help to sustain their engagement. Support from employers, including time off and flexible schedules, and making plans for future involvement were crucial to their continued volunteer activity. IMPACT STATEMENT: Changing demographics and a limited understanding of volunteer leadership could leave APTA with a limited pool of leaders into the future. Understanding the reasons early career professionals volunteer in APTA can help develop more effective strategies to recruit and retain these leaders.

Professional development and lifelong learning: the impact of physical therapy residency training in Kenya.

Introduction: To assist with the professional development of physical therapists in Kenya, a post-graduate residency program was developed and implemented in the country.Purpose: The purpose of this study was to explore the influence of residency training on the professional development of physical therapists.Methods: The influence of the program on professional development of residents was explored through a mixed-methods research design, including a survey and semi-structured interviews with residents at program completion.Results: The graduates reported a positive impact of residency education on their ability to perform a comprehensive evaluation, utilize clinical reasoning, provide an effective treatment to achieve projected outcomes, treat complex patients, communicate with patients and other health professionals, perform overall patient management, and implement a treatment plan based on scientific literature. Four themes emerged from the interviews: 1) evolution of practice from protocol-driven to individualized treatment plans; 2) promotion of professional development within the wider physical therapy community; 3) positive change in physical therapy practice; and 4) commitment to lifelong learning.Conclusion: The residents expressed how their new knowledge and skills fostered their commitment to providing mentorship to colleagues and lifelong learning. This commitment can provide the framework for advancing the practice of physical therapy in their respective communities.

Knee Strength and Ankle Range of Motion Impacts on Timed Function Tests in Duchenne Muscular Dystrophy: In the Era of Glucocorticoids.

BACKGROUND: Duchenne Muscular Dystrophy (DMD) is a neuromuscular disorder that presents in childhood and is characterized by slowly progressive proximal weakness and lower extremity contractures that limit ambulatory ability [1, 2]. Contractures develop in the ankles, knees, and hips due to muscle imbalances, fibrotic changes, loss of strength, and static positioning [2, 5]. Currently, standards of care guidelines emphasize the importance of maintaining good musculoskeletal alignment through stretching, bracing, and glucocorticoid (GC) therapy to preserve strength and function. METHODS: This is a retrospective analysis of prospectively collected data through the CINRG Duchenne Natural history study (DNHS). The objectives of this analysis are to understand the progression of ankle contractures for individuals with DMD and to investigate the relationship between progressive lower limb contractures, knee strength, and Timed Function Tests.A collection of TFTs including supine to stand (STS), 10 meter walk test (10MWT), and timed stair climbing (4SC) have been used to monitor disease progression and are predictive of loss of ambulation in these patients [4]. Multiple factors contribute to loss of ambulation, including progressive loss of strength and contracture development that leads to changing biomechanical demands for ambulation. A better understanding of the changes in strength and range of motion (ROM) that contribute to loss of function is important in a more individualized rehabilitation management plan. In this longitudinal study, we measured strength using quantitative muscle testing (QMT) with the CINRG Quantitative Measurement System (CQMS)), ROM was measuresed with a goniometer and TFTs were measured using a standard stopwatch and methodology. RESULTS: We enrolled 440 participants; mean baseline age was 8.9 (2.1, 28.0) years with 1321 observations used for analysis. GC use was stratified based on duration on drug with 18.7%at < 6 months or naïve; 4.3%<1 year; 58.0%1 < 10 years; and 19.3%between 10-25 years of GC use. Ankle ROM was better for those on GC compared to GC naive but did not significantly influence long-term progression rates. QMT, ROM, age and GCs contribute to speed of TFTs. Knee extension (KE) strength and Dorsiflexion (DF) ROM are significant predictors of speed for all TFTs (p < 0.001). Of the variables used in this analysis, KE strength is the primary predictor of walking speed, estimating that every pound increase in KE results in a 0.042 m/s improvement in 10MWT, and a smaller similar increase of 0.009 m/s with every degree of ankle DF ROM. CONCLUSION: GC use provides an improvement in strength and ROM but does not affect rate of change. Knee strength has a greater influence on speed of TFTs than DF ROM, although both are statistically significant predictors of speed. Results show that retaining knee strength [1, 2], along with joint flexibility, may be important factors in the ability to perform walking, climbing and supine to stand activities.

The Minimal Clinical Important Difference (MCID) in Annual Rate of Change of Timed Function Tests in Boys with DMD.

BACKGROUND: Duchenne muscular dystrophy (DMD) is a rare x-linked recessive genetic disorder affecting 1 in every 5000-10000 [1, 2]. This disease leads to a variable but progressive sequential pattern of muscle weakness that eventually causes loss of important functional milestones such as the ability to walk. With promising drugs in development to ameliorate the effects of muscle weakness, these treatments must be associated with a clinically meaningful functional change. OBJECTIVE: The objective of this analysis is to determine both distribution, minimal detectable change (MDC), and anchor-based, minimal clinically important difference, (MCID) of 12 month change values in standardized time function tests (TFT) used to monitor disease progression in DMD. METHOD: This is a retrospective analysis of prospectively collected data from a multi-center prospective natural history study with the Cooperative International Neuromuscular Research Group (CINRG). This study calculated MDC and MCID values for 3 commonly used timed function tests typically used to monitor disease progression; supine to stand (STS), 10 meter walk/run (10MWT), and 4 stair climb (4SC). MDC used standard error of measurement (SEM) while MCID measurements used the Vignos scale as an anchor to determine clinical change in functional status. RESULTS: All 3 TFT were significantly important clinical endpoints to detect MDC and MCID changes. MDC and MCID 12 month changes were significant in 10MWT (-0.138, -0.212), Supine to Stand (-0.026, -0.023) and 4 stair climb (-0.034, -0.035) with an effect size greater or close to 0.2. CONCLUSION: The 3 TFT are clinically meaningful endpoints used to establish change in DMD. MCID values were higher than MDC values indicating that an anchor-based approach using Vignos as a clinically meaningful loss of lower extremity abilities is appropriate to assess change in boys with DMD.

Influence of residency training on the clinical reasoning development of Kenyan physiotherapists.

Objective: The purpose of this study was to explore the clinical reasoning development of physical therapists participating in an 18-month orthopaedic residency program in Nairobi, Kenya. Methods: A mixed methods research design was utilized. The participants' clinical reasoning was assessed through a live patient examination prior to entering the residency program and upon graduation. One-on-one interviews were performed with the residents to explore their clinical reasoning during the final examination. Results: Residents (n = 14) demonstrated a statistically significant improvement in their ability to perform an examination of a patient and determine a hypothetical diagnosis. The clinical reasoning process described by the participants included the hypothetical deductive and narrative reasoning models. The residents did not appear to incorporate pattern recognition during the patient assessment. Discussion: Similar to studies on novice and expert practice in physical therapy, residents demonstrated an improvement in cue acquisition, the ability to verify and refute a hypothetical diagnosis, and the ability to match interventions to patients impairments. In addition, the residents utilized a combination of clinical reasoning models during the examination and evaluation of the patient including hypothetical deductive reasoning and narrative reasoning. Level of Evidence: 4.

Barriers and Facilitators for a Collaborative International Physical Therapist Residency Program in Nairobi, Kenya.

Introduction: With the globalization of higher education through online training, opportunities exist for collaboration between institutions to promote ongoing advancement of healthcare professionals in resource-limited countries. The success of these programs is dependent on the ability of the program to meet the educational needs of the student and assist with implementation of the new information into practice. A post graduate residency program for physical therapists was introduced to Kenya to promote the development of the profession of physical therapy. This study sought to explore barriers that affected participation in the residency program, and how participants perceived the residency program fostered the use of new skills in the clinical environment, as well as the limitations they faced in applying the skills gained through the residency program in a clinical setting. Methods and Materials: The participants in this study were in the third and fourth cohorts of the residency program (n = 27). One-on-one interviews were performed with the residents following completion of the program. A qualitative phenomenology research design was used to describe the manner in which the residency was experienced within the context of the environment in which the experience took place. Descriptions and narratives were obtained from the residents to provide a window into their lived experience. Results: Four themes were discovered: (1) The ongoing challenge to balance often conflicting responsibilities: family, work and education, (2) A need to educate patients and colleagues on newly acquired skills to gain acceptance, (3) Success in the program requires reliance on support networks, and (4) Increased confidence gained in delivery of patient care. Discussion: Although the residents faced obstacles for completing the residency and integrating newly acquired knowledge and skills into clinical practice, they were able to formulate strategies to meet these challenges. Understanding the barriers and facilitators that affect participants in international collaborative efforts may ultimately assist residency and other educational programs in designing new models of education, which will advance the physical therapy profession globally.

Test-retest reliability and construct validity of the tinetti performance-oriented mobility assessment in people with stroke.

BACKGROUND AND PURPOSE: The Tinetti Performance-Oriented Mobility Assessment (POMA) is commonly used to measure balance ability in older adults. The purpose of this study was to determine the test-retest reliability and minimal detectable change (MDC) of the POMA and explore its cross-sectional and longitudinal construct validity for use in people early after stroke. METHODS: Participants were recruited if they had a first documented stroke and were receiving physical therapy during inpatient rehabilitation. The POMA, gait speed, and motor Functional Independence Measure (FIM) scores were collected at admission and at discharge from inpatient rehabilitation. A second trial of the POMA was conducted 1 day after the first trial for reliability analysis. Correlations (Spearman ρ) between raw scores of admission and discharge outcome measures, as well as change in scores between admission and discharge, were used to explore the construct validity of the POMA. RESULTS: Fifty-five people, with average age of 75 ± 11 years, who had experienced first documented stroke participated in the study and began inpatient physical therapy at a mean of 8 ± 5 days poststroke. Test-retest reliability intraclass correlation coefficient (ICC2,1) was 0.84 and MDC was 6 points. The POMA scores were moderately correlated to motor FIM and gait speed scores at admission (rs = 0.55 and 0.70) and discharge (rs = 0.55 and 0.82.) Change scores of all 3 measures had a fair correlation (rs = 0.28-0.51). DISCUSSION AND CONCLUSIONS: Test-retest reliability and MDC of the POMA in people with stroke is similar to previous research in older adult long-term care residents. Results support cross-sectional and longitudinal construct validity of the POMA in persons early after stroke and demonstrate validity and reliability to measure balance ability in this population.Video Abstract available (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A39) for more insights from the authors.
