Academy of Geriatric Physical Therapy Research Agenda: Rationale for the Development and the Intent for Use.

The rationale for the development and the intent for use of a research agenda for the Academy of Geriatric Physical Therapy is described. The reasons for the research agenda for geriatric physical therapy are (1) to have a broad representation of the research conducted by physical therapist(s) working with older adults, (2) to provide guidance and assistance to emerging investigators to aid the trajectory of a research career, and (3) as a document to engage potential funding agencies, foundations, and individuals in support of physical therapist-conducted research. The design was based on the Research Agenda for Physical Therapy (APTA document), formatted to be consistent with the World Health Organization International Classification of Functioning, Disability and Health, priority ratings for the research statements, and specific examples of research questions for each category of the Research Agenda. The Academy of Geriatric Physical Therapy Research Agenda generated to be a living document, with revisions to research questions and priority ratings expected in the future to enable the agenda to adapt to changes in science, practice, workforce, education, and health policy.

Student Perceptions of a Live Standardized Patient Interprofessional Education Scenario: A Multi-Year Study.

PURPOSE: This qualitative study examined perceptions of interprofessional education (IPE) and professional roles following a standardized patient experience in occupational therapy (OT) and physical therapy (PT) students. RATIONALE: Simulation-based learning experiences offer effective means to enhance IPE. Limited research exists in OT and PT about student perceptions of IPE and professional roles following a standardized patient experience. DESIGN: Perceptions of OT and PT students were measured using a pre/post questionnaire design in a mixed-methods study, with the qualitative component presented in this article. METHODS: One hundred students participated (51 second-year OT, 49 third-year PT students). Students completed a questionnaire regarding interprofessional practice and professional roles within the healthcare team. Students participated in small group interdisciplinary case work, faculty-led discussion, and a simulated patient case. Students completed a post survey with additional questions regarding the experiences. Data were analyzed using an inductive coding methodology. FINDINGS: Two main themes were identified: student outcomes (subthemes: scope of practice, team communication and collaboration) and IPE design (subthemes: team composition, curricular sequence, amount of time for experience). CONCLUSIONS: These findings relay perceptions of IPE and professional roles following a standardized patient experience. Further modification to the curricular timeframe and experience design should be explored with IPE experiences.

Live Standardized Patient Scenario Improves Attitudes Toward and Readiness for Interprofessional Education in Occupational Therapy and Physical Therapy Students.

PURPOSE: This study examined the impact of video-based and live standardized patient scenarios on attitudes toward and readiness for interprofessional education (IPE) in occupational therapy (OT) and physical therapy (PT) students. In academic health programs, IPE is used to teach the knowledge and skills to develop interprofessional teamwork abilities; however, research is limited on the impact of standardized patient scenario experiences (SPSE) on the effectiveness of IPE in OT and PT students. PARTICIPANTS: The study involved 49 participants: 23 OT and 26 PT students. METHODS: A descriptive quantitative pilot study measured attitudes and readiness for IPE using a repeated-measures design and the Readiness for Inter-Professional Learning Scale (RIPLS), a 19-item Likert scale. Students completed the RIPLS prior to an interprofessional team assignment, following an interprofessional team meeting to plan the standardized patient evaluation, and after a live SPSE. A 3 x 2 repeated-measures MANOVA analyses was used to determine differences between groups and change over time. RESULTS: Statistically significant changes occurred in Teamwork and Professional Identify subscales of the RIPLS for both groups after the live SPSE. IMPACT: Findings support the use of team-based, live SPSE to improve OT and PT students' readiness for and attitudes toward IPE.

Sensory-Challenge Balance Exercises Improve Multisensory Reweighting in Fall-Prone Older Adults.

BACKGROUND AND PURPOSE: Multisensory reweighting (MSR) deficits in older adults contribute to fall risk. Sensory-challenge balance exercises may have value for addressing the MSR deficits in fall-prone older adults. The purpose of this study was to examine the effect of sensory-challenge balance exercises on MSR and clinical balance measures in fall-prone older adults. METHODS: We used a quasi-experimental, repeated-measures, within-subjects design. Older adults with a history of falls underwent an 8-week baseline (control) period. This was followed by an 8-week intervention period that included 16 sensory-challenge balance exercise sessions performed with computerized balance training equipment. Measurements, taken twice before and once after intervention, included laboratory measures of MSR (center of mass gain and phase, position, and velocity variability) and clinical tests (Activities-specific Balance Confidence Scale, Berg Balance Scale, Sensory Organization Test, Limits of Stability test, and lower extremity strength and range of motion). RESULTS: Twenty adults 70 years of age and older with a history of falls completed all 16 sessions. Significant improvements were observed in laboratory-based MSR measures of touch gain (P = 0.006) and phase (P = 0.05), Berg Balance Scale (P = 0.002), Sensory Organization Test (P = 0.002), Limits of Stability Test (P = 0.001), and lower extremity strength scores (P = 0.005). Mean values of vision gain increased more than those for touch gain, but did not reach significance. DISCUSSION AND CONCLUSIONS: A balance exercise program specifically targeting multisensory integration mechanisms improved MSR, balance, and lower extremity strength in this mechanistic study. These valuable findings provide the scientific rationale for sensory-challenge balance exercise to improve perception of body position and motion in space and potential reduction in fall risk.

Participation restriction, not fear of falling, predicts actual balance and mobility abilities in rural community-dwelling older adults.

BACKGROUND AND PURPOSE: Fear of falling (FOF) has been correlated with an increased risk for falls, self-restriction of physical activity, and subsequent decrease in quality of life in older adults. The relationship between perceived FOF, participation restriction, and balance and mobility abilities is unclear, as results from prior studies are inconsistent. Few studies have used the Survey of Activities and Fear of Falling in the Elderly (SAFE) as a standard measure of FOF, although this survey provides both a measure of FOF and participation restriction. Only one study has explored the relationship of individual items from the SAFE with balance and mobility tests that predict fall risk. The primary purpose of this study was to investigate the relationships between FOF and participation restriction as measured by the SAFE and actual balance and mobility abilities in a diverse group of older adults. PARTICIPANTS: Eighty-two community-dwelling older adults (17 men) with a mean age of 74 (SD = 8.8; range = 55-91) participated in this study. The sample comprised 45% African Americans and 54% whites. METHODS: Fear of falling and participation restriction were assessed using the SAFE, a self-assessment survey. The SAFE assesses information about participation in 11 functional activities as well as the extent to which fear is a source of participation restriction. Balance and functional mobility were measured using the Berg Balance Scale (BBS) and Timed Get Up & Go Test (TUG), respectively. Participants were categorized as low (N = 36), mixed (N = 19), or high (N = 24) risk for future falls based on their past fall history and results on the BBS and the TUG. Data analysis included χ(2) and Spearman correlation and 2 regression analyses. RESULTS: Both SAFE FOF and participation restriction scores were significantly correlated with BBS and TUG scores. However, SAFE participation restriction scores, but not SAFE FOF scores, predicted BBS and TUG scores. SAFE FOF scores could discriminate older adults at high risk for falls from those at mixed and low risk but could not discriminate between the mixed- and low-risk groups. DISCUSSION/CONCLUSION: The relationship between self-reported participation restriction and objectively measured balance and mobility abilities is stronger than the relationship between self-reported FOF and objectively measured balance and mobility abilities. These findings lend support to the argument that participation restriction may be the critical mediating factor between FOF, balance and mobility limitations, and fall risk. Evaluation of and intervention for FOF and fall risk without direct and specific attention to participation restriction may not yield optimal results. Older adults whose goals include both reduction in fall risk and increase in participation level may need combined treatment approaches.

The dynamics of visual reweighting in healthy and fall-prone older adults.

Multisensory reweighting (MSR) is an adaptive process that prioritizes the visual, vestibular, and somatosensory inputs to provide the most reliable information for postural stability when environmental conditions change. This process is thought to degrade with increasing age and to be particularly deficient in fall-prone versus healthy older adults. In the present study, the authors investigate the dynamics of sensory reweighting, which is not well-understood at any age. Postural sway of young, healthy, and fall-prone older adults was measured in response to large changes in the visual motion stimulus amplitude within a trial. Absolute levels of gain, and the rate of adaptive gain change were examined when visual stimulus amplitude changed from high to low and from low to high. Compared with young adults, gains in both older adult groups were higher when the stimulus amplitude was high. Gains in the fall-prone elderly were higher than both other groups when the stimulus amplitude was low. Both older groups demonstrated slowed sensory reweighting over prolonged time periods when the stimulus amplitude was high. The combination of higher vision gains and slower down weighting in older adults suggest deficits that may contribute to postural instability.

Multisensory reweighting of vision and touch is intact in healthy and fall-prone older adults.

Unexplained falls in older adults are thought to arise from subtle deficits in multiple components of the postural control system, including peripheral sensory loss and central sensory processing. One commonly proposed central sensory processing deficit is a decline in the adaptive use of changing or conflicting sensory inputs for estimating body dynamics, i.e., multisensory reweighting. We examined the assumption of impaired multisensory reweighting in healthy and fall-prone older adults using quantitative methods that have previously demonstrated reweighting in young adults. Standing subjects were exposed to simultaneous medio-lateral oscillatory visual and fingertip touch inputs at varying relative amplitudes. No group differences in overall levels of vision and touch gain were found. Both healthy and fall-prone older adults demonstrated the same pattern of adaptive gain change as healthy young adults. Like the young adults, both elderly groups displayed clear evidence of intra- and inter-sensory reweighting to both vision and touch motion stimuli. These data suggest that, for small amplitude vision and touch stimuli, the central sensory reweighting adaptation process remains intact in healthy and fall-prone older adults with sufficiently intact peripheral sensation.
