Project description:Posttraumatic stress disorder (PTSD) affects up to 30% of military veterans. Older veterans, many of whom have lived with PTSD symptoms for several decades, report a number of negative health outcomes. Despite the demonstrated benefits of regular exercise on physical and psychological health, no studies have explored the impact of exercise in older veterans with PTSD. This paper describes the development, design, and implementation of the Warrior Wellness exercise pilot study for older veterans with PTSD. Veterans aged ≥60 with a Diagnostic and Statistical Manual of Mental Disorders (DSM-V) diagnosis of PTSD will be recruited and randomized to (a) Warrior Wellness, a 12-week supervised, facility-based exercise intervention, or (b) usual care for 12 weeks. Warrior Wellness is a theory- and evidence-based behavioral intervention that involves 3 sessions per week of multi-component exercise training that targets strength, endurance, balance, and flexibility. Warrior Wellness focuses on satisfaction with outcomes, self-efficacy, self-monitoring, and autonomy. Factors associated with program adherence, defined as the number of sessions attended during the 12 weeks, will be explored. Primary outcomes include PTSD symptoms and cardiovascular endurance, assessed at baseline and 12 weeks. Compared to those in usual care, it is hypothesized that those in the Warrior Wellness condition will improve on these efficacy outcomes. The Warrior Wellness study will provide evidence on whether a short-term exercise intervention is feasible, acceptable, and effective among older veterans with PTSD, and explore factors associated with program adherence.

Project description:Older veterans with posttraumatic stress disorder (PTSD) are at increased risk of obesity and cardiometabolic disease. Physical activity and healthy eating are two behaviors that impact health, functional independence, and disease risk in later life, yet few studies have examined the relationship between PTSD and diet quality. This secondary analysis aimed to: (a) characterize the diet quality of older veterans with PTSD in comparison to U.S. dietary guidelines and (b) explore if participation in a supervised exercise intervention spurred simultaneous changes in dietary behavior. Diet quality was assessed with the Dietary Screener Questionnaire (DSQ), which measures daily intake of fiber, calcium, added sugar, whole grain, dairy, and fruits/vegetables/legumes. The sample included 54 military veterans ≥ 60 years old with PTSD who participated in a randomized controlled pilot trial comparing 12 weeks of supervised exercise (n = 36) to wait-list usual care (n = 18). The DSQ was administered at baseline and 12 weeks. Consumption of added sugar exceeded U.S. dietary guideline recommendations and consumption of whole grains, fruits/vegetables/legumes, fiber, calcium, and dairy fell short. Participation in the supervised exercise intervention was not associated with changes in diet quality. Results revealed that the diet quality of older veterans with PTSD is poor, and while the exercise intervention improved health through exercise, it did not make veterans any more likely to adopt a more healthful diet. Interventions targeting diet, or diet + exercise, are needed to manage the increased risk of obesity and cardiometabolic disease present in older veterans with PTSD.

Project description:BackgroundMilitary veterans living with post-traumatic stress disorder (PTSD) face significant physical and functional health disparities, which are often aggravated over time and in the context aging. Evidence has shown that physical activity can positively impact age-related health conditions, yet exercise trials in older adults with mental disorders are rare. Our study was a tailored and targeted pilot exercise intervention for older veterans with PTSD.MethodsFifty-four older veterans with PTSD (mean age = 67.4 years, 90.7% male, 85.2% non-white) were randomized to supervised exercise (n = 38) or wait-list usual care (n = 18) for 12 weeks. Physical activity (MET-min/wk) and aerobic endurance (assessed with the 6-minute walk test) were primary outcomes. Secondary outcomes were physical performance (strength, mobility, balance), cardiometabolic risk factors (eg, waist circumference), and health-related quality of life.ResultsAt 12 weeks, a large effect of the intervention on physical activity levels (Cohen's d = 1.37) was observed compared to wait-list usual care. Aerobic endurance improved by 69 m in the exercise group compared to 10 m in wait-list group, reflecting a moderate between-group effect (Cohen's d = 0.50). Between-group differences on 12-week changes in physical performance, cardiometabolic risk factors, and health-related quality of life ranged from small to large effects (Cohen's d = 0.28-1.48), favoring the exercise arm.ConclusionParticipation in supervised exercise improved aerobic endurance, physical performance, and health-related clinical factors in older veterans with PTSD; a medically complex population with multiple morbidity. Group exercise is a low-cost, low-stigma intervention, and implementation efforts among older veterans with PTSD warrants further consideration.

Project description:Anxiety is characterized by excessive attention to threatening information, leading to impaired working memory (WM) performance and elevated anxious thoughts. Preliminary research indicates that individuals with PTSD show particular difficulty with WM in emotional contexts (Schweizer et al., 2011). Although several studies show that computerized training can improve WM capacity for anxious individuals (Owens et al., 2013; Schweizer et al., 2011; 2013), there has been very little research on WM training for PTSD or with Veterans (Saunders et al., 2015). In a pilot randomized trial, we assigned Veterans with elevated PTSD symptoms to an online emotional WM training, either adaptive (n-back; n = 11) or a less potent training (1-back; n = 10). Overall, both groups showed significant decreases in PTSD symptoms. The n-back group showed a trend of outperforming the 1-back group in improving reexperiencing symptoms (which are likely to be associated with impaired WM functioning). This population anecdotally found the intervention quite challenging, which may be why even the less potent 1-back was still helpful. These preliminary findings justify the effort for developing new WM-focused PTSD intervention for complex, vulnerable populations, particularly as online training can improve accessibility.

Project description:PurposeThe study aimed to determine the feasibility of remotely delivered exercise (tele-exercise) for older, rural cancer survivors and to explore the effects of tele-exercise on physical function, physical activity, and patient-reported outcomes.MethodsParticipants were rural cancer survivors age ≥ 60 years (79% female; mean age 70.4 ± 5.7) randomly assigned to the remotely delivered EnhanceFitness (tele-EF) exercise program, inclusive of aerobic, strength, and balance training and led by American Council on Exercise certified instructors for 1 h, 3 days/week for 16 weeks (n = 20) or to a waitlist control group (n = 19). We assessed feasibility, physical function, accelerometer-measured physical activity, and patient-reported outcomes at baseline and post intervention.ResultsAmong those screened as eligible, 44 (64%) consented to participate with 39 randomized after completing baseline measures. Attrition was equivalent between groups (n = 1, each) with 95% completing the study. The median class attendance rate was 86.9% (interquartile range: 79-94%). Compared to controls, tele-EF participants had statistically significant improvement in the five-time sit-to-stand test (- 3.4 vs. - 1.1 s, p = 0.03, effect size = 0.44), mean daily light physical activity (+ 38.5 vs 0.5 min, p = 0.03, effect size = 0.72) and step counts (+ 1977 vs. 33, p = 0.01, effect size = 0.96). There were no changes in self-efficacy for exercise, fatigue, or sleep disturbance between groups.ConclusionsFindings indicate that tele-EF is feasible in older, rural cancer survivors and results in positive changes in physical function and physical activity.Implications for cancer survivorsTele-EF addresses common barriers to exercise for older, rural cancer survivors, including limited accessible opportunities for professional instruction and supervision.

Project description:Subthreshold posttraumatic stress disorder (PTSD) is associated with increased risk for suicidality, depression, and functional impairment. We thus conducted a small (N=12) pilot randomized controlled trial (RCT) with paroxetine for subthreshold PTSD in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) era veterans. Hospital Anxiety and Depression Scale (HADS) scores improved by 30.4% in the paroxetine group. Paroxetine may have promise for subthreshold PTSD.

Project description:BackgroundIn addition to generally high levels of physical activity, multi-component exercise training is recommended for the maintenance of health and fitness in older adults, including the prevention of falls and frailty. This training often encompasses serial sequencing of balance, strength, endurance and other types of exercise. Exercise training featuring integrative training of these components (i.e. agility training) has been proposed, as it more likely reflects real life challenges like stop-and-go patterns, cutting manoeuvers, turns and decision-making. In this study, we compared the efficacy of an agility-based training to the traditional strength and balance training approach with regard to selected risk factors for falls and frailty.MethodsWe trained twenty-seven community-dwelling healthy seniors (16♂; 11♀; age: 69.5 ± 5.3 y; BMI: 26.4 ± 3.7 kg/m2) for 8 weeks in a group setting with 3 sessions per week, each lasting 50 minutes. Participants were randomized into either the agility group (AGI; n = 12), that used the integrative multi-component training, or the traditional strength and balance group (TSB; n = 15). TSB performed balance and strength exercises separately, albeit within the same session. The training of both groups progressively increased in difficulty. Outcomes were static and dynamic balance (single leg eyes open stand, Y-balance test, reactive balance), lower limb (plantar flexion and dorsal extension) and trunk flexion and extension maximum strength and rate of torque development (RTD). In addition, we tested endurance by the six-minute walk test (6MWT). We calculated linear mixed effects models for between-groups comparisons as well as effect sizes (ES) with 95 % confidence intervals.ResultsSmall ES in favor of AGI were found for plantar flexion strength (ES > 0.18[-0.27;0.89]) and RTD (ES > 0.43[-0.19;1.36]) as well as trunk extension RTD (ES = 0.35[-0.05;0.75]). No other parameters showed notable between group differences. Compliance was high in both groups (AGI: 90 ± 8% of sessions; TSB: 91 ± 7% of sessions).DiscussionAgility-based exercise training seems at least as efficacious as traditional strength and balance training in affecting selected physical performance indicators among community-dwelling healthy seniors. In particular, lower limb and trunk extension explosive strength seem to benefit from the agility training.

Project description:Objective The aim of this study was to compare the effects of multicomponent and strength training programs on dynamic balance, functional capacity, and gait ability in older women. Methods Thirty individuals (67?±?4.3 years; 30.6?±?3.9?kg/m2) were trained for 12 weeks (3 times per week), following multicomponent (MG: exercises focusing on agility, balance, muscle strength, and aerobic) and strength programs (SG: lower limbs strength exercise). Results Peak torque of hip flexors (p=0.020) and extensors (p=0.009) and knee flexors (p=0.001) of SG was greater than that of MG at posttraining. In addition, both groups increased peak torque of knee extensors (p=0.002) and plantar extensors with higher effect size for SG (d?=??0.41 and ?0.48), whereas MG presented higher effect size for plantar flexors muscles (d?=??0.55). Only the SG improved the rate of torque development of knee extensors (29%; p=0.002), and this variable was also greater to SG than MG at posttraining (106%). The SG and MG improved dynamic balance although SG presented higher effect size (d?=?0.61). Both groups improved the performance on 30 s sit to stand test (p=0.010) with higher effect size for MG (d?=??0.54). Only the MG improved the stride length (4%; p=0.011) and gait speed (10%; p=0.024). In addition, the groups improved toe clearance (p=0.035) and heel contact (p=0.010) with higher effect sizes for MG (d?=??0.066 and 1.07). Conclusion Strength training should be considered to increase muscle function and dynamic balance in older women, whereas multicomponent training should be considered to increase functional capacity and gait ability in this population.

Project description:BackgroundAlthough vibration training has been applied in older adults, it remains unclear if it can reduce falls.AimsThis pilot randomized-controlled trial aimed to test the effects of an 8-week vibration training program on reducing falls among community-dwelling adults.MethodsForty-eight older adults were randomized to two groups: training and control. The training group received three weekly training sessions over eight weeks while the control group maintained their normal lifestyle over the 8-week period. Immediately before (or baseline), following (post-training), and three months after (retest) the 8-week training course, a group of fall risk factors were assessed for all participants. Each participant was also exposed to an unexpected gait-slip on a treadmill during post-training and retest sessions. Their daily-living fall incidence was collected for 12 months after the baseline test. The slip fall was the primary outcome, prospective all-cause falls were the secondary outcome, and fall risk factors acted as the tertiary ones.ResultsThe vibration training program significantly reduced the risk of slip-falls and improved all fall risk factors immediately after the training course. The training effect may be carried over for three months. The 8-week training program could also lower the number of falls between the baseline test and retest and reduce the recurrent faller rate across the 12 months after the baseline test.DiscussionThis study indicates that vibration training might have some effects on fall-related measures in older adults.ConclusionsAn 8-week vibration training program could be effective to reduce falls in older adults.ClinicaltrialsGov registration numberNCT02694666.
