The OTAGO exercise programme is effective in decreasing the risk for falls of older adults. This research investigated if there is an indication that the OTAGO exercise programme has a positive effect on the capacity and as well as on the performance in mobility. We used the data of the 10-months observational OTAGO pilot study with 15 (m = 1, f = 14) (pre-)frail participants aged 84.60 y (SD: 5.57 y). Motion sensors were installed in the flats of the participants and used to monitor their activity as a surrogate variable for performance. We derived a weighted directed multigraph from the physical sensor network, subtracted the weights of one day from a baseline, and used the difference in percent to quantify the change in performance. Least squares was used to compute the overall progress of the intervention (n = 9) and the control group (n = 6). In accordance with previous studies, we found indication for a positive effect of the OTAGO program on the capacity in both groups. Moreover, we found indication that the OTAGO program reduces the decline in performance of older adults in daily living. However, it is too early to conclude causalities from our findings because the data was collected during a pilot study.

Abstract Background: There is compelling evidence that physical activity positively influences quality of life (QoL), and health-related outcomes including improved muscle mass and physical functioning in cancer pts. SCT pts however have unique barriers to exercise including isolation, restriction of activities, and treatment toxicity. In the early post SCT period, pts describe worsening fatigue, physical capacity and QoL. We sought to determine whether a partially supervised exercise intervention early post SCT would address these issues. Our primary objective was to determine the feasibility of delivering such an intervention at our institution. Secondary objectives were to assess changes as a result of the intervention in QoL, muscle mass and physical functioning. Methods: From Aug 2015-Jun 2016, we conducted a prospective single-arm study to evaluate feasibility of a 12 week partially supervised exercise program (1 supervised, 2 unsupervised sessions/week) for alloSCT pts with hematologic malignancies. The program consisted of 3 progressive endurance (stationary bike, walking) and 2 resistance training sessions/week, from hospital discharge (D/C) to Day (D) 100. Feasibility was defined as ability to recruit >65% of eligible pts, ≥70% retention and ≥70% adherence. Secondary outcomes were measured pre SCT (T0), at D/C (T1) and D100 (T2) and included QoL, muscle strength, mobility, aerobic fitness and body composition. Changes from T0 to T1 and T1 to T2 were compared using a paired sample t-test. Results: Of 43 consecutive alloSCT pts assessed for eligibility, 30 (70%) entered the study: 17 male (57%), median age 48 yrs (range 19-66 yrs). Transplants characteristics were: related 6; unrelated 24; myeloablative 23; reduced intensity 7. At baseline, SCT comorbidity index was 0 in 43%, 1-2 37%, ≥ 3 20%. Pts self-reported exercising enough to break a sweat (Godin et al) never 60%, sometimes 33%, often 7%. Median hospitalization was 29d (range 15-141); 9 pts developed grade II-IV acute graft-versus-host disease (skin 7, gut 5, liver 1). Overall retention to D100 was 80% (Figure 1). Two pts had complications during hospitalization and did not enter the program. Of the 24 pts who entered the program, adherence was 72% for supervised and 89% for unsupervised sessions. Logistics with scheduling around multiple medical appointments in the early post SCT period were the most common reasons for non-adherence. Other reasons included nausea, fatigue and weakness. One pt developed exercise-induced atrial fibrillation in week 3 requiring cessation of exercise. When comparing secondary outcomes from T0 to T1 (Table 1), pts had significantly decreased muscle strength (grip strength, 30-second chair stand), mobility (timed up-and-go [TUG]) and aerobic capacity (6-min walk test [6MWT]). At T2 after completion of the program, these measures all increased significantly when compared to T1. Global QoL scores on the EORTC measure decreased from T0 to T1 (P=.011) and were significantly improved by T2 (P<.001). Similar trends were seen across functional and symptom measure scales. Body composition comparisons between T0 and T2 demonstrated a trend towards increased appendicular lean mass (P<.059). Conclusion: Results of this pilot study demonstrate feasibility of a partially supervised exercise program post-alloSCT deemed by achieving the target recruitment rate, ≥70% adherence and ≥70% retention. Logistics were the most common reason for non-adherence, highlighting need for a multidisciplinary team with knowledge of the post SCT setting. Prior observational studies have shown significant declines in physical functioning and QoL within the first 100 days of SCT. In contrast we demonstrate significant improvements in these measures. Furthermore, we demonstrate a trend towards increased lean muscle mass, which is a novel secondary outcome that warrants further evaluation in this setting. Our findings support the need for this clinical intervention and will be evaluated in a larger randomized trial. Disclosures Gerrie: Roche Canada: Research Funding. Plantinga:BCCA: Employment.

AbstractWe have previously identified three balance mechanisms that young healthy adults use to maintain balance while walking. The three mechanisms are: 1) The lateral ankle mechanism, an active modulation of ankle inversion/eversion in stance; 2) The foot placement mechanism, an active shift of the swing foot placement; and 3) The push-off mechanism, an active modulation of the ankle plantarflexion angle during double stance. Here we seek to determine whether there are changes in neural control of balance when walking at different cadences and speeds. Twenty-one healthy young adults walked on a self-paced treadmill while immersed in a 3D virtual reality cave, and periodically received balance perturbations (bipolar galvanic vestibular stimulation) eliciting a perceived fall to the side. Subjects were instructed to match two cadences specified by a metronome, 110bpm (High) and 80bpm (Low), which led to faster and slower gait speeds, respectively. The results indicate that subjects altered the use of the balance mechanisms at different cadences. The lateral ankle mechanism was used more in the Low condition, while the foot placement mechanism was used more in the High condition. There was no difference in the use of the push-off mechanism between cadence conditions. These results suggest that neural control of balance is altered when gait characteristics such as cadence change, suggesting a flexible balance response that is sensitive to the constraints of the gait cycle. We speculate that the use of the balance mechanisms may be a factor resulting in well-known characteristics of gait in populations with compromised balance control, such as slower gait speed in older adults or higher cadence in people with Parkinson’s disease.

Falls among older adults are often attributed to declining muscle strength with ageing. Associations between muscle strength and balance control have been reported, but the evidence for, and key mechanisms of resistance exercise in fall prevention are unclear. No studies have directly examined the relationship between muscle fibre characteristics and reactive balance control. Here, we address whether or not Type II muscle fibre characteristics associate with reactive balance during walking in young and older adults with varying muscle fibre type composition. We analyse muscle biopsy-derived fibre characteristics and stability during a treadmill-based walking perturbation (trip-like) task of healthy young adults, healthy, normally active older adults, trained older adults and physically impaired older adults. We find no significant associations between Type II muscle fibre properties and reactive balance during walking, indicating that practitioners and researchers should consider more than just the muscle tissue properties when assessing and intervening on fall risk.
