- Peak Cardiorespiratory Responses of Patients with Subacute Stroke During Land and Aquatic Treadmill Exercise. [JOURNAL ARTICLE]
- Am J Phys Med Rehabil 2016 Aug 19.
The aim of this work was to investigate the cardiorespiratory responses of patients with subacute stroke to exercise stress tests with aquatic and land treadmills.Twenty-one consecutive patients who presented with first-ever subacute stroke in 2013-2015. All subjects underwent symptom-limited incremental exercise testing with aquatic and land treadmills. Land treadmill speed started at 1.5 km/h and increased 0.5 km/h every 1 to 2 minutes until maximal tolerable speed was achieved. Thereafter, the grade was elevated by 2% every 2 minutes. In the aquatic treadmill test, subjects were submerged to the xiphoid in 28°C water. Treadmill speed started at 1.5 km/h and was increased 0.5 km/h every 2 minutes thereafter. Cardiorespiratory responses were recorded with aquatic and land treadmills.Compared to land treadmill exercise, aquatic treadmill exercise achieved significantly better peak VO2 (22.0 vs 20.0; P = 0.02), peak metabolic equivalents (6.3 vs 5.8; P = 0.02), and peak rating of perceived exertion (17.6 vs 18.4, P = 0.01). Heart rate and VO2 correlated significantly during both tests (land treadmill: r = 0.96, P < 0.001; aquatic treadmill: r = 0.99, P < 0.001).Aquatic treadmill exercise elicited significantly better peak cardiorespiratory responses than land treadmill exercise and may be as effective for early intensive aerobic training in subacute stroke patients.
- Effect of aquatic dual-task training on balance and gait in stroke patients. [Journal Article]
- J Phys Ther Sci 2016 Jul; 28(7):2044-7.
[Purpose] The purpose of this study was to determine the effect of aquatic dual-task training on balance and gait in stroke patients. [Subjects and Methods] Twenty stroke patients were divided into the experimental (n=10) and control (n=10) groups. Both groups underwent neurodevelopmental treatment. The experimental group additionally underwent aquatic dual-task training for 30 minutes a day, 5 days a week, for 6 weeks. Balance was measured using the Berg balance scale, Five Times Sit-to Stand Test, and Functional Reach Test. Gait was measured using the 10-Meter Walk Test, Timed Up and Go Test, and Functional Gait Assessment. [Results] For intragroup comparison, the experimental group showed a significant change after the experiment in all balance and gait assessment tests. For intergroup comparison, the experimental group showed relatively more significant change after the experiment in all balance and gait assessment tests. [Conclusion] Our results showed that aquatic dual-task training has a positive effect on balance and gait in stroke patients.
- The effect of aquatic exercise on physical functioning in the older adult: a systematic review with meta-analysis. [JOURNAL ARTICLE]
- Age Ageing 2016 Jul 4.
ageing and sedentary behaviour cause negative changes in the neuromuscular systems of healthy older adults resulting in a decrease in physical functioning. Exercising in water (aquatic exercise, AE) has been shown to be effective at improving physical functioning in this population; however, no systematic review with meta-analysis has been published.to investigate the effect of AE on physical functioning in healthy older adults compared to control or land-based exercise (LE) through a systematic review with meta-analysis of randomised controlled trials.Medline, Embase, Cinahl, PEDro, SPORTDiscus, Web of Science, Cochrane Library, published before 31st December 2015.in total, 28 studies met the inclusion criteria and were included in the systematic review; 24 studies with 1,456 subjects (89% female) and with mean age 66.4 years were included in the meta-analysis.data were extracted and checked for accuracy by three independent reviewers.size of treatment effect was measured using the standardised mean difference with 95% confidence intervals (CIs).compared to control interventions, AE had a moderate positive effect on physical functioning 0.70 [95% CI 0.48 to 0.92]. Compared to LE, AE had a small positive effect on physical functioning 0.39 [0.12 to 0.66].there is a high risk of bias and low methodological quality in the studies particularly when comparing AE to LE with possible over estimation of the benefit of AE.AE may improve physical functioning in healthy older people and is at least as effective as LE.
- Assessing auditory evoked potentials of wild harbor porpoises (Phocoena phocoena). [Journal Article]
- J Acoust Soc Am 2016 Jul; 140(1):442.
Testing the hearing abilities of marine mammals under water is a challenging task. Sample sizes are usually low, thus limiting the ability to generalize findings of susceptibility towards noise influences. A method to measure harbor porpoise hearing thresholds in situ in outdoor conditions using auditory steady state responses of the brainstem was developed and tested. The method was used on 15 live-stranded animals from the North Sea during rehabilitation, shortly before release into the wild, and on 12 wild animals incidentally caught in pound nets in Denmark (inner Danish waters). Results indicated that although the variability between individuals is wide, the shape of the hearing curve is generally similar to previously published results from behavioral trials. Using 10-kHz frequency intervals between 10 and 160 kHz, best hearing was found between 120 and 130 kHz. Additional testing using one-third octave frequency intervals (from 16 to 160 kHz) allowed for a much faster hearing assessment, but eliminated the fine scale threshold characteristics. For further investigations, the method will be used to better understand the factors influencing sensitivity differences across individuals and to establish population-level parameters describing hearing abilities of harbor porpoises.
- A new approach to the improvement of quality of life in fibromyalgia: a pilot study on the effects of an aquatic Ai Chi program. [JOURNAL ARTICLE]
- Int J Rheum Dis 2016 Jul 26.
Fibromyalgia syndrome (FMS) is a rheumatic disorder that presents with physical, psychological and social symptoms.The aim of this study was to assess the effects of a program of water-based Ai Chi on the health-related quality of life of subjects with FMS.An experimental pilot study was performed with a sample of 20 female subjects diagnosed with FM and recruited from two different settings. Assessments were performed using the a visual analog scale and the Short Form-36 physical and mental health summary scores. Measurements took place at baseline and upon completion of 10 treatment sessions.After 10 treatment sessions, significant improvements (P < 0.05) were found in practically all the variables under study, with significant differences in values such as pain perception, vitality, mental health, as well as perceived overall improvement in quality of life.A water-based Ai Chi program may contribute to the improvement of mental and physical health and the quality of life in women with FMS.
- Qualitative perspectives on aquatic exercise initiation and satisfaction among persons with multiple sclerosis. [JOURNAL ARTICLE]
- Disabil Rehabil 2016 Jun 26.:1-6.
To identify the individual and social experiences underlying the initiation and satisfaction with aquatic exercise among persons with MS.A convenience sample (n = 45) of persons aged ≥18 with MS who had engaged in water-based exercise within the previous six months completed a 60-90 min semi-structured telephone interview regarding their aquatic exercise experiences.An aquatic exercise history was not a prerequisite for the adoption of aquatic exercise. Rather, participants described aquatic exercise routines as stemming from recognition of a decline in physical function combined with encouragement and invitations to join aquatic programs. Despite regular visits, health care providers were not a common source of information regarding the feasibility of aquatic exercise. Participants' aquatic activities included MS-specific and generalized aquatics courses, with class satisfaction resting on the instructor, class "fit" and a feeling of acceptance.Communication regarding local aquatic opportunities is critical for ensuring aquatics engagement among persons with MS. Providers could play a stronger role in emphasizing the feasibility and benefits of aquatic programs. In addition, persons with MS should be encouraged to try local MS and more generalized aquatic programs in order to identify a program matching their social and physical goals. Implications for Rehabilitation Directed communication regarding aquatic opportunities is essential to prompting the initiation of aquatic exercise Both MS-specific and general aquatics classes can provide positive exercise experiences for persons with MS A history of regular exercise or aquatic experiences is not a prerequisite for the initiation of aquatic exercise among persons with MS Health care provider visits may represent missed opportunities for promoting aquatics; providers should consider the suitability of aquatics for all patients with MS, regardless of the patient's exercise history.
- Exercise Benefits for Chronic Low Back Pain in Overweight and Obese Individuals. [REVIEW, JOURNAL ARTICLE]
- PM R 2016 Jun 23.
Overweight and obese individuals with chronic low back pain (LBP) struggle with the combined physical challenges of physical activity and pain interference during daily life; perceived disability increases, pain symptoms worsen, and performance of functional tasks and quality of life (QOL) decline. Consistent participation in exercise programs positively affects several factors including musculoskeletal pain, perceptions of disability due to pain, functional ability, QOL, and body composition. It is not yet clear, however, what differential effects occur among different easily accessible exercise modalities in the overweight-obese population with chronic LBP. This narrative review synopsizes available randomized and controlled, or controlled and comparative, studies of easily accessible exercise programs on pain severity, QOL, and other outcomes, such as physical function or body composition change, in overweight-obese persons with chronic LBP. We identified 16 studies (N = 1,351) of various exercise programs (aerobic exercise [AX], resistance exercise [RX], aquatic exercise [AQU], and yoga-Pilates) that measured efficacy on LBP symptoms, and at least one other outcome such as perceived disability, QOL, physical function, and body composition. RX, AQU, and Pilates exercise programs demonstrated the greatest effects on pain reduction, perceived disability, QOL, and other health components. The highest adherence rate occurred with RX and AQU exercise programs, indicating that these types of programs may provide a greater overall impact on relevant outcomes for overweight-obese LBP patients.
- Identifying knowledge gaps in seagrass research and management: An Australian perspective. [JOURNAL ARTICLE]
- Mar Environ Res 2016 Jun 16.
Seagrass species form important marine and estuarine habitats providing valuable ecosystem services and functions. Coastal zones that are increasingly impacted by anthropogenic development have experienced substantial declines in seagrass abundance around the world. Australia, which has some of the world's largest seagrass meadows and is home to over half of the known species, is not immune to these losses. In 1999 a review of seagrass ecosystems knowledge was conducted in Australia and strategic research priorities were developed to provide research direction for future studies and management. Subsequent rapid evolution of seagrass research and scientific methods has led to more than 70% of peer reviewed seagrass literature being produced since that time. A workshop was held as part of the Australian Marine Sciences Association conference in July 2015 in Geelong, Victoria, to update and redefine strategic priorities in seagrass research. Participants identified 40 research questions from 10 research fields (taxonomy and systematics, physiology, population biology, sediment biogeochemistry and microbiology, ecosystem function, faunal habitats, threats, rehabilitation and restoration, mapping and monitoring, management tools) as priorities for future research on Australian seagrasses. Progress in research will rely on advances in areas such as remote sensing, genomic tools, microsensors, computer modeling, and statistical analyses. A more interdisciplinary approach will be needed to facilitate greater understanding of the complex interactions among seagrasses and their environment.
- Non-use Economic Values for Little-Known Aquatic Species at Risk: Comparing Choice Experiment Results from Surveys Focused on Species, Guilds, and Ecosystems. [Journal Article]
- Environ Manage 2016 Sep; 58(3):476-90.
Accounting for non-market economic values of biological diversity is important to fully assess the benefits of environmental policies and regulations. This study used three choice experiments (species-, guild-, and ecosystem-based surveys) in parallel to quantify non-use values for little-known aquatic species at risk in southern Ontario. Mean willingness-to-pay (WTP) ranged from $9.45 to $21.41 per listing status increment under Canada's Species at Risk Act for both named and unnamed little-known species. Given the broad range of valuable ecosystem services likely to accrue to residents from substantial increases in water quality and the rehabilitation of coastal wetlands, the difference in WTP between species- and ecosystem-based surveys seemed implausibly small. It appeared that naming species-the 'iconization' of species in two of the three surveys-had an important effect on WTP. The results suggest that reasonable annual household-level WTP values for little-known aquatic species may be $10 to $25 per species or $10 to $20 per listing status increment. The results highlighted the utility of using parallel surveys to triangulate on non-use economic values for little-known species at risk.
