Unlocking the black box of geriatric physiotherapy : Quantification of physical activity and walking parameters during inpatient geriatric rehabilitation therapy sessions.

BACKGROUND: Physiotherapy and occupational therapy are currently described using the duration of treatment (days or weeks), the frequency of therapy sessions (on a daily or 3-5 days per week basis) and considering the duration of a session (e.g., 30 or 45 min). The content is often poorly defined and the intensity is rarely reported. Using digital technology some of these shortcomings can be overcome. The cumulative parameters of walking and activity sessions, the duration of walking, the time spent in an upright or lying/sitting position and the number of steps can now be analyzed. In this study, we examined the parameters during non-treatment periods and therapy time in patients recovering from fragility fractures. METHODS: The study is a secondary data analysis of a trial that examined the improvement of physical activity (PA) and self-efficacy of fragility fracture patients. Changes in mobility parameters were measured using the ActivPal3 sensor during the 1st and 3rd weeks of rehabilitation and 104 patients were analyzed (mean age 82.5 years). Parameters included the time during supervised treatment, the mean number of steps, cumulative time in an upright position and walking duration, the number of walking intervals of > 10 s and sit to stand transfers. RESULTS: Patients received 3-4 therapy sessions adding up to 90-120 min per day. More than 50% of the daily walking activities were achieved in these sessions until discharge. With this amount of therapeutic input most parameters meaningfully improved from baseline to the second measurement. The number of steps increased by 30%, the mean time in an upright position increased by 26% and the mean time spent walking increased by 49%. CONCLUSION: The sensor-derived measurements describe the amount of walking activity administered during the supervised therapy sessions. This could be used as a starting point for future trials to improve the outcomes or as a standard of process evaluation for clinical services.

Change of physical activity parameters of hip and pelvic fracture patients during inpatient rehabilitation and after discharge: analysis of global and in-depth parameters.

BACKGROUND: A growing number of older adults suffer hip and pelvic fractures leading to hospital admission. They often result in reduced physical activity (PA) and impaired mobility. PA can be objectively measured with body-worn sensors. Usually, global cumulative PA parameters are analysed, such as walking duration, upright-time and number of steps. These traditional parameters mix different domains of PA, such as physical capacity (PC), behaviour and living environment. We examined the change of global cumulative PA measures during rehabilitation and after discharge in patients with hip or pelvic fracture and whether more 'in-depth' PA parameters, such as walking interval length, variability of interval length and sit-to-stand transitions and their changes during rehabilitation and 3 months after discharge might better reflect the above mentioned three clinically relevant domains of PA. METHODS: This study is a secondary data analysis of a randomised controlled trial to improve PA and fall-related self-efficacy in hip or pelvic fracture patients (≥60 years) with concerns about falling. Changes of accelerometer-measured global cumulative and in-depth PA parameters (activPAL3) were analysed in an observational design before and after discharge combining both groups. For comparison, the same analyses were applied to the traditional PC measures gait speed and 5-chair-rise. RESULTS: Seventy-five percent of the 111 study participants were female (mean age: 82.5 (SD = 6.76) years. Daily walking duration, upright time and number of steps as aspects of global PA increased during inpatient rehabilitation as well as afterwards. The in-depth PA parameters showed differing patterns. While the total number of walking bouts increased similarly, the number of longer walking bouts decreased by 50% after discharge. This pattern was also seen for the average walking interval length, which increased by 2.34 s (95% confidence interval (CI): 0.68; 4.00) during inpatient rehabilitation and decreased afterwards below baseline level (- 4.19 s (95% CI: - 5.56; - 2.82)). The traditional PC measures showed similar patterns to the in-depth PA parameters with improvements during rehabilitation, but not at home. CONCLUSION: Our findings suggest that the in-depth PA parameters add further information to the global cumulative PA parameters. Whereas global cumulative PA parameters improved significantly during inpatient rehabilitation and after discharge, in-depth PA parameters as well as PC did not continuously improve at home. In contrast to global cumulative PA parameters the in-depth parameters seem to reflect contextual factors such as the build environment and aspects of PC, which are traditionally assessed by clinical PC measures. These in combination with digital mobility measures can help clinicians to assess the health status of fragility fracture patients, individually tailor therapy measures and monitor the rehabilitation process.

German version of the outcome expectations for exercise scale-2 : Psychometric properties in geriatric patients after hip or pelvic fractures with fear of falling.

OBJECTIVE: Physical exercise is associated with many health benefits. Especially for older adults it is challenging to achieve an appropriate adherence to exercise programs. The outcome expectations for exercise scale 2 (OEE-2) is a 13-item self-report questionnaire to assess negative and positive exercise outcome expectations in older adults. The aim of this study was to translate the OEE­2 into German and to assess the psychometric properties of this version. METHODS: The OEE­2 was translated from English into German including a forward and backward translation process. Psychometric properties were assessed in 115 patients with hip/pelvic fractures (76% female, mean age 82.5 years) and fear of falling during geriatric inpatient rehabilitation. RESULTS: Principal component analyses could confirm a two-factor solution (positive/negative OEE) that explained 58% of the total variance, with an overall internal reliability of α = 0.89. Cronbach's α for the 9­item positive OEE subscale was 0.89, for the 4­item negative OEE subscale 0.79. The two subscales were correlated with rs = 0.49. Correlations of the OEE total score were highest with the perceived ability to manage falls, prefracture leisure time activities and prior training history (rs = 0.35-0.41). CONCLUSION: These results revealed good internal reliability and construct validity of the German version of the OEE­2. The instrument is valid for measuring physical exercise outcome expectations in older, German-speaking patients with hip or pelvic fractures and fear of falling.

Effects of an intervention to reduce fear of falling and increase physical activity during hip and pelvic fracture rehabilitation.

BACKGROUND: fear of falling and reduced fall-related self-efficacy are frequent consequences of falls and associated with poorer rehabilitation outcomes. To address these psychological consequences, geriatric inpatient rehabilitation was augmented with a cognitive behavioural intervention ("Step by Step") and evaluated in a RCT. METHODS: one hundred fifteen hip and pelvic fracture patients (age = 82.5 years, 70% female) admitted to geriatric inpatient rehabilitation were randomly allocated to the intervention or control group. The intervention consisted of eight additional individual sessions during inpatient rehabilitation, one home visit and four telephone calls delivered over 2 months after discharge. Both groups received geriatric inpatient rehabilitation. Primary outcomes were fall-related self-efficacy (short falls efficacy scale-international) and physical activity as measured by daily walking duration (activPAL3™ sensor) after admission to rehabilitation, before discharge and 1-month post-intervention. RESULTS: in covariance analyses, patients in the intervention group showed a significant improvement in fall-related self-efficacy (P = 0.025, d = -0.42), but no difference in total daily walking duration (P = 0.688, d = 0.07) 1-month post-intervention compared to the control condition. Further significant effects in favour of the intervention group were found in the secondary outcomes "perceived ability to manage falls" (P = 0.031, d = 0.41), "physical performance" (short physical performance battery) (P = 0.002, d = 0.58) and a lower "number of falls" (P = 0.029, d = -0.45). CONCLUSIONS: the intervention improved psychological and physical performance measures but did not increase daily walking duration. For the inpatient part of the intervention further research on the required minimum intensity needed to be effective is of interest. Duration and components used to improve physical activity after discharge should be reconsidered.

Correlates of fear of falling and falls efficacy in geriatric patients recovering from hip/pelvic fracture.

OBJECTIVE: To gain a better understanding about the nature of fear of falling, this study analyzed associations between psychological and physical aspects related to fear of falling and falls efficacy in hip/pelvic fracture patients. DESIGN: Baseline data of a randomized controlled trial. SETTING: Geriatric inpatient rehabilitation hospital. SUBJECTS: In all, 115 geriatric patients with hip/pelvic fracture (mean age: 82.5 years) reporting fear of falling within first week of inpatient rehabilitation. INTERVENTIONS: None. MAIN MEASURES: Falls efficacy (Short Falls Efficacy Scale-International; Perceived Ability to Manage Falls), fear of falling (one-item question), fall-related post-traumatic stress symptoms (six items based on Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) criteria), physical performance (Short Physical Performance Battery) and psychological inflexibility (Acceptance and Action Questionnaire-II) were assessed. RESULTS: Path analyses demonstrated that low falls efficacy (Short Falls Efficacy Scale International) was significantly related to poor physical performance (ß* = -.277, P ⩽ .001), but not to psychological inflexibility and fall-related post-traumatic stress symptoms (P ⩾ .05.). Fear of falling was directly associated with fall-related post-traumatic stress symptoms (ß*= .270, P = .007) and indirectly with psychological inflexibility (ß*= .110, P = .022). Low perceived ability to manage falls was significantly related to previous falls (ß* = -.348, P ⩽ .001), psychological inflexibility (ß* = -.216, P = .022) and female gender (ß* = -.239, P ⩽ .01). CONCLUSION: Falls efficacy and fear of falling constitute distinct constructs. Falls efficacy measured with the Short Falls Efficacy Scale International reflects the appraisal of poor physical performance. Fear of falling measured by the single-item question constitutes a fall-specific psychological construct associated with psychological inflexibility and fall-related post-traumatic stress symptoms.

[The osteoporotic fracture prevention program in rural areas (OFRA): analysis of 1092 mobility courses in rural areas]. / Trittsicher durchs Leben: Analyse von 1092 Bewegungskursen im ländlichen Raum.

BACKGROUND: Specific training reduces the risk of falls and fall-related injuries in older persons. The availability of specific exercise programs in Germany, especially in rural areas is scarce. Therefore, a healthcare fund driven program osteoporotic fracture prevention program in rural areas (OFRA) (German name: "Trittsicher durchs Leben") was implemented in rural areas in 47 counties of 5 federal states. The most important components of the program are the "Trittsicher" mobility course and falls prevention classes organized by members of the German Association of Rural Women and executed by exercise instructors of the German Gymnastics Association or physiotherapists. Since the start of the program in October 2015 more than 2300 classes have been carried out. AIM: The study analyzed the structural characteristics of the first 1092 "Trittsicher" mobility courses and the characteristics of the 12,246 participants. METHOD: The analysis is based on data of a standardized course documentation sheet and information from an internal database of a health insurance company. Additionally, the distance between the location of the course and place of residence was determined for a subgroup of the participants. RESULTS: The classes were conducted in communal and confessional rooms, in sports associations, kindergartens and restaurants. The majority of the 12,246 participants were female (89.1%), the median age was 75 years. The average size of the classes was 11.2 participants per course. More than half of the participants attended all six sessions. Half of the participants of the courses had to travel less than 1.7 km between the place of residence and the location of the courses. CONCLUSION: "Trittsicher" mobility courses are a new specific offer to improve mobility and reduce the risk of falling. They contribute to a better care of older people in rural areas.

Hip and pelvic fracture patients with fear of falling: development and description of the "Step by Step" treatment protocol.

OBJECTIVE: Based on a theoretical framework and sound evidence, this article describes a rehabilitation programme for patients with fear of falling after hip and pelvic fracture. RATIONALE: Based on exercise science principles, current knowledge from fall prevention, emotion regulation, and the Health Action Process Approach we developed a theoretical framework, from which the components of the intervention were derived. Description of the intervention: The intervention consists of 6 components: (1) relaxation, (2) meaningful activities and mobility-based goals, (3) falls related cognitions and emotions, coping with high risk tasks and situations, (4) individual exercise programme, (5) planning and implementing exercises and activities, and (6) fall risks and hazards. The intervention comprises of 8 individual sessions during 3 to 5 weeks of inpatient rehabilitation and 4 telephone calls and 1 home visit over a 2-month post-discharge period. Each session or telephone call takes about 30-60 minutes. It is provided to geriatric hip and pelvic fracture patients with concerns about falling and no cognitive impairment. To ensure completeness of reporting, the Template for Intervention Description and Replication (TIDierR) is used. RESULTS: Fifty-seven patients were assigned to the intervention group. All 46 completers met all pre-defined criteria for an intervention per protocol. CONCLUSION: The programme is feasible to administer. We have completed a randomised controlled trial, which will be submitted in due time (for trial protocol: www.isrctn.org ; ISRCTN79191813).

The osteoporotic fracture prevention program in rural areas (OFRA): a protocol for a cluster-randomized health care fund driven intervention in a routine health care setting.

BACKGROUND: Fragility fractures are one of the leading causes for disability in old people. The main underlying mechanisms are osteoporosis and falls. Evidence-based measures to prevent either falls or fractures are available. However, coordinated preventive approaches combining bone health and fall prevention are rare. The objective of the study is to evaluate a health care fund driven program, which encourages insured persons to adhere to national guidelines regarding bone health and physical activity and falls prevention. The health care fund cooperates with the 'German Association of Rural Women' and the 'German Gymnastics Association'. The program consists of mobility and falls prevention classes, the examination of bone health by a DXA scan, and a consultation about 'safety in the living environment'. METHODS: Cluster-randomized study in 47 intervention and 143 control districts in 5 federal states of Germany. The program is offered to a) community-living women and men aged 70 to <85 years with a prior fragility fracture or b) community-living women aged 75 to <80 years. Within two years more than 10,000 persons will be directly contacted and motivated to make use of the components of the program. The primary outcome is a combined measure of incident osteoporotic fractures. Secondary outcomes include the rate of referrals to a mobility and falls prevention class or a bone mass density measurement. An economic evaluation will be conducted. DISCUSSION: The study evaluates a complex preventive intervention in a routine health care setting which may serve as model for similar approaches in other areas or countries.
