Can Treadmill Slip-Perturbation Training Reduce Longer-Term Fall Risk Upon Overground Slip Exposure?

The purpose was to examine and compare the longer-term generalization between 2 different practice dosages for a single-session treadmill slip-perturbation training when reexposed to an overground slip 6 months later. A total of 45 older adults were conveniently assigned to either 24 or 40 slip-like treadmill perturbation trials or a third control group. Overground slips were given immediately after initial training, and at 6 months after initial training in order to examine immediate and longer-term effects. The performance (center of mass stability and vertical limb support) and fall percentage from the laboratory-induced overground slips (at initial posttraining and at 6 mo) were measured and compared between groups. Both treadmill slip-perturbation groups showed immediate generalization at the initial posttraining test and longer-term generalization at the 6-month retest. The higher-practice-dosage group performed significantly better than the control group (P < .05), with no difference between the lower-practice-dosage and the control groups at the 6-month retest (P > .05). A single session of treadmill slip-perturbation training showed a positive effect for reducing older adults’ fall risk for laboratory-induced overground slips. A higher-practice dosage of treadmill slip perturbations could be more beneficial for further reducing fall risk.

Perturbed Walking

This study examined the effects of perturbation training on the contextual interference and generalization of encountering a novel opposing perturbation. One hundred and sixty-nine community-dwelling healthy older adults (69.6 ± 6.4 years) were randomly assigned to one of the three groups: slip-perturbation training (St, n = 67) group received 24 slips, trip-perturbation training (Tt, n = 67) group received 24 trips, and control (Ctrl: n = 31) group received only non-perturbed walking trials (ClinicalTrials.gov NCT03199729; https://clinicaltrials.gov/ct2/show/NCT03199729). After training, all groups had 30 min of rest and three post-training non-perturbed walking trials, followed by a reslip and a novel trip trial for St, a retrip and a novel slip trial for Tt, and randomized novel slip and trip trials for Ctrl. The margin of stability (MOS), step length, and toe clearance of post-training walking trials were compared among three groups to examine interferences in proactive adjustment. Falls, MOS at the instant of recovery foot touchdown, and hip height of post-training perturbation trials were investigated to detect interferences and generalization in reactive responses. Results indicated that prior adaptation to slip perturbation training, resulting in walking with a greater MOS (more anterior) and a shorter step length (p < 0.01) than that of the Ctrl group, would be associated with a greater likelihood to forward balance loss if encountered with a trip. The trip adaptation training mainly induced a higher toe clearance during walking (p < 0.01) than the Ctrl group, which could lead to reduced effectiveness of the reactive response when encountered with a novel slip. However, there was no difference in the reactive MOS, limb support, and falls between the control group and the slip and trip training groups on their respective opposing novel perturbation post-training (MOS, limb support, and falls for novel slip: Tt = Ctrl; for the novel trip: St = Ctrl, both p > 0.05). Current findings suggested that, although perturbation training results in proactive adjustments that could worsen the reactive response (interference) when exposed to an unexpected opposing perturbation, older adults demonstrated the ability to immediately generalize the training-induced adaptive reactive control to maintain MOS, to preserve limb support control, and to reduce fall risk.

Honey Yield

This study was carried out to determine the effects of additive feeding with pollen and water on honey yield, colony population, winter loses and wintering ability of colonies in pine honey production season in Muğla province of Turkey. Total twenty honeybee colonies had similar physiological pattern (queen age, genotype, amount of adult worker bees (number of frames covered with adult worker bees), sealed brood areas (cm2) and food stocks) were used and randomly divided into four groups. Three of them were fed extra with pollen+water, pollen and water. The control colonies were not given additive foods. Honey yield in pollen+water, pollen, water and control groups were found to be 24.2±1.1, 17.3±0.8, 16.3±1.0 and 12.0±0.6 kg/colony respectively. Group means were statistically significant. From September 25 to February 15 (wintering), losses of the adult worker bees in pollen+water, pollen, water and control groups were 50%, 69%, 68% and 82%, decrease of sealed brood areas in the groups were 48%, 66%, 68% and 85%, respectively. Wintering ability of pollen+water, pollen, water and control groups were found to be 92.1±3.2, 70.4±17.8, 67.1±16.7 and 51.0±21.2% respectively. The results showed that additive feeding in pine honey production season, especially feeding with both pollen+water provided nearly 100% more honey production and 80% better wintering ability than the control group. In addition, feeding with only pollen or water had similar positive effect (approximately 40%) better than control group

Introduction: To evaluate fall-prevention rehabilitative slippers for use by self-caring, independent older adults. Materials and Methods: This assessor-blinded, randomized, and controlled 1-year study included 59 self-caring, independent participants (49 women) who attended day services. The mean age of participants was 84.0 ± 5.3 years. Participants were randomly selected from 8 nursing homes. We tested slippers top-weighted with a lead bead (200, 300, or 400 g). Intervention group participants walked while wearing the slippers for 10-20 min, 1-3 days/week at the day service center. Fall risk was measured using the Berg Balance Scale and the Tinetti Performance-Oriented Mobility Assessment (POMA) before and at 3-month intervals after the intervention/control phase. Results: After 12 months, the intervention group demonstrated significant improvement. Berg Balance and POMA compared to the control group ( p < .05 p < .01, respectively). Mobility scores improved significantly for both measurements in the intervention group before and after ( p < .01), but the control group had significantly lower scores. Discussion: Overall, falls decreased in the intervention group from 10 to 7, and control group falls increased from 9 to 16 ( p = .02). No adverse events related to the intervention were reported. Conclusions: Rehabilitation training slippers may reduce falls in older adults.

Positive Effect

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.

Golf Putt

The Five-Step Strategy (FSS) consists of (a) readying oneself, (b) imaging the desired outcome, (c) focusing on the task at hand, (d) freeing the mind, and (e) evaluating the outcome afterward. This study examined its usefulness as an instructional aid for older adults. Because some (Molander & Backman, 1989) have found that older adults have more anxiety during competitive sport experiences, another purpose was to examine whether the FSS can reduce anxiety. One group used the FSS when learning a golf putt; a second learned the putt without using the FSS. Participants putted for three 1-hr sessions once a week. Performance and anxiety were assessed before the first and after the second and third sessions. Retention scores revealed that the FSS group learned the task better than the control group did, t(27) = 6.63, p < .001. These findings suggest that the FSS might help older adults learn motor skills.

Pilot Randomized Controlled Trial

Objective To assess the preliminary effects of a buddy-style intervention to improve exercise adherence. Design A parallel-group, open-label, pilot randomized controlled trial. Setting Adult day-care centers. Participants Sixty-five disabled older adults. Interventions All participants underwent a 12-week home exercise program, and the intervention group received a 5–10 min buddy-style intervention between older adults in the intervention group once weekly at an adult day-care center. Main measures Based on the exercise log calendar, the number of days of exercise was assessed for each of the three phases: 1–4 weeks, 5–8 weeks, and 9–12 weeks. Short physical performance battery was measured at baseline and after 12 weeks. Results Of the 590 screened older adults, 65 were recruited and 33 were assigned to the intervention group. One participant in each group withdrew before the program began, and four and five patients in the intervention and control groups, respectively, dropped out by the 12-week assessment. Analysis of covariance of the 28 and 26 patients in the intervention and control groups, respectively, for whom exercise log calendars could be retrieved, showed that the intervention group (24.4/28 days) exercised significantly more days than the control group (20.6/28 days) at 9–12 weeks ( P = 0.009). In the between-group effect of the intention-to-treat analysis of short physical performance battery, walking and standing test ( P = 0.790, P = 0.829) were not significantly different, and balance test ( P = 0.049) was significantly better in the control group. Conclusions There was a preliminary effect of the buddy-style intervention to improve exercise adherence.
