Is Aquatic Therapy Optimally Prescribed for Parkinson's Disease? A Systematic Review and Meta-Analysis

Research progress on the application of anti-gravity treadmill in the rehabilitation of Parkinson's disease patients: a mini review

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by motor and non-motor symptoms. It is the second most common chronic progressive neurodegenerative disease. PD still lacks a known cure or prophylactic medication. Current treatments primarily address symptoms without halting the progression of PD, and the side effects of dopaminergic therapy become more apparent over time. In contrast, physical therapy, with its lower risk of side effects and potential cardiovascular benefits, may provide greater benefits to patients. The Anti-Gravity Treadmill is an emerging rehabilitation therapy device with high safety, which minimizes patients' fear and allows them to focus more on a normal, correct gait, and has a promising clinical application. Based on this premise, this study aims to summarize and analyze the relevant studies on the application of the anti-gravity treadmill in PD patients, providing a reference for PD rehabilitation practice and establishing a theoretical basis for future research in this area.

The effects of Brazilian dance, deep-water exercise and nordic walking, pre- and post-12 weeks, on functional-motor and non-motor symptoms in trained PwPD

BACKGROUND

Motor and non-motor symptoms affect functional autonomy, mobility and daily life activities in People with Parkinson's Disease (PwPD). Brazilian Dance (BD), Deep-water exercise (DWE), and Nordic Walking (NW) are well-accepted, low-cost, and safe non-pharmacological strategies for untrained PwPD. However, no previous studies have investigated and compared the effects of these interventions on trained PwPD.

OBJECTIVE

To describe and compare the effects of BD, DWE and NW, pre- and post-12 weeks, on functional-motor and non-motor symptoms in trained PwPD.

METHODS

Eighty-three trained PwPD were randomly assigned into three groups: BD (n = 31), DWE (n = 21) and NW (n = 31), that participated in one of the interventions for 12 weeks. We applied Timed up and go at two speeds (self-selected and fast); 6-min and 10-meter walk test; Sit-to-Stand and handgrip test; Unified Parkinson Disease Rating Scale - III; Falls Efficacy Scale; Montreal Cognitive Assessment questionnaire; and Parkinson's Disease Questionnaire-39. The main (group and time) and interaction effects were analyzed using GEE analysis (p<0.05).

RESULTS

Statistical differences were found between groups in the handgrip test (p<0.01), the time (p = 0.04), and interaction group*time (p< 0.01) in the Sit-to-stand test. While BD improved the Sit-to-stand test performance (ES=1.00; large effect size), DWE and NW remained unchanged (ES=0.16 and ES=0.14; low effect size).

CONCLUSION

BD, DWE, and NW maintained most of the functional-motor and non-motor symptoms in trained PwPD. BD was shown to be more effective at improving strength in the lower limbs, when compared to NW and DWE.

Effect of aquatic exercise programs according to the International Classification of Functionality, Disability and Health domains in individuals with Parkinson's disease: a systematic review and meta-analysis with GRADE quality assessment

PURPOSE

To investigate the effects of aquatic exercise programs (AEP) in body structure and function, activity, and participation outcomes in individuals with Parkinson's disease (PD) with mild to moderate disability levels.

METHODS

Six databases were searched from inception until November 2022. Randomized clinical trials that used AEP alone, AEP combined and/or compared two types of AEP were included. The quality of evidence was assessed by the GRADE approach and the standardized mean differences (SMD) were calculated the meta-analysis.

RESULTS

Twelve studies (n = 380) were included. AEP alone was superior to active control in improving body structure and function outcome: postural balance (low evidence, SMD = 0.47, p = 0.02). No statistically significant differences were found for the other body structure and function outcomes: lower limb muscle strength (p = 0.14) and depressive symptoms (p = 0.79), activity outcomes: mobility (p = 0.32) and participation outcomes: quality of life (p = 0.05). AEP combined showed no statistically significant difference for the outcomes of body structure and function: postural balance (p = 0.11) and activity: mobility (p = 0.21) when compared to active control.

CONCLUSION

AEP showed positive effects on body structure and function outcome (postural balance) in individuals with PD with mild to moderate disability levels while, no significant improvements were noticed for activity and participation outcomes.IMPLICATIONS FOR REHABILITATIONOur findings indicate that aquatic exercise programs (AEP) lead to significant improvements on body structure and function (i.e., postural balance) in individuals with Parkinson's disease (PD).The AEP evaluated in this study implemented postural balance, gait, single and double training, as well as aerobic exercises, trunk mobility exercises, and Ai Chi.The average duration, frequency, and total time implemented were 50 minutes, three times a week, for seven weeks, respectively.Considering the potential benefits identified in this study, AEP can be recommended as an adjunct treatment strategy for individuals with PD.Additionally, the use of the International Classification of Functionality, Disability and Health on the development of rehabilitation treatment plans is advised.

Long-term efficacy of hydrotherapy on balance function in patients with Parkinson's disease: a systematic review and meta-analysis

Background

Hydrotherapy can improve the motor and non-motor symptoms of Parkinson's disease (PD), but the long-term effects of hydrotherapy on PD are still unclear.

Objective

The purpose of this systematic evaluation and meta-analysis was to explore the long-term effects of hydrotherapy on balance function in PD patients.

Methods

A systematic search of five databases was conducted to identify appropriate randomized controlled trials (RCTs) according to the established inclusion and exclusion criteria. The general characteristics and outcome data (balance, exercise, mobility, quality of life, etc.) of the included studies were extracted, and the quality of the included studies was evaluated using the Cochrane risk of bias assessment tool. Finally, the outcome data were integrated for meta-analysis.

Results

A total of 149 articles were screened, and 5 high-quality RCTs involving 135 PD patients were included. The results of the meta-analysis showed positive long-term effects of hydrotherapy on balance function compared to the control group (SMD = 0.69; 95% CI = 0.21, 1.17; p = 0.005; I2 = 44%), However, there were no significant long-term effects of hydrotherapy on motor function (SMD = 0.06; 95% CI = -0.33, 0.44; p = 0.77; I2 = 0%), mobility and quality of life (SMD = -0.21; 95% CI = -0.98, 0.57; p = 0.6; I2 = 71%). Interestingly, the results of the sensitivity analysis performed on mobility showed a clear continuation effect of hydrotherapy on mobility compared to the control group (SMD = -0.80; 95% CI = -1.23, -0.37; p < 0.001; I2 = 0%).

Conclusion

The long-term effects of hydrotherapy on PD patients mainly focus on balance function, and the continuous effects on motor function, mobility, and quality of life are not obvious.

Physical exercise and its effects on people with Parkinson's disease: Umbrella review

INTRODUCTION

Parkinson's disease is neurodegenerative, complex and progressive, manifesting in a slow and irreversible way. Physical exercise has been proposed as therapeutic alternative to people with Parkinson´s disease.

OBJECTIVE

To synthesize knowledge about the effects of physical exercise on people with Parkinson´s Disease as presented by published systematic reviews.

METHODS

Nine electronic databases and two grey literature databases were searched for systematic reviews reporting the effects of physical exercises on people with Parkinson´s Disease. Searches involved a two-phase process, by, at least, two independent reviewers. Methodological quality of the included systematic reviews was assessed using AMSTAR-2.

RESULTS

From 2,122 systematic reviews, 139 were included. Motor outcomes were assessed in 91% of the studies, with balance being the most studied. Non-motor outcomes were assessed in 68% of the studies, with emphasis on quality of life. Physical exercises were classified into five categories: aerobic exercises, strength, combined, sensorimotor activities and other activity protocols. Findings of the systematic reviews suggest that all exercise categories can be prescribed to improve balance and mobility, while combined exercises, strength, and specific activities improve both motor and non-motor outcomes, and aerobic exercise and sensorimotor activities improve motor outcomes.

CONCLUSION

Current evidence from systematic reviews suggests that physical exercises impacts both motor and non-motor outcomes in people with Parkinson´s Disease. Limits in evidence provided by the systematic reviews were related to methodological issues and to the description of the interventions and must be considered to improve decision-making and clinical application.

Effectiveness of the aquatic physical therapy exercises to improve balance, gait, quality of life and reduce fall-related outcomes in healthy community-dwelling older adults: A systematic review and meta-analysis

BACKGROUND

Opting to use aquatic or land-based physical therapy exercises to improve balance, gait, quality of life and reduce fall-related outcomes in community-dwelling older adults (CDOAs) is still a questionable clinical decision for physiotherapists.

OBJECTIVE

Assess the quality of evidence from randomized or quasi-randomized controlled trials that used aquatic physical therapy exercises to improve balance, gait, quality of life and reduce fall-related outcomes in CDOAs.

METHODS

Articles were surveyed in the following databases: MEDLINE/PubMed, EMBASE, SCOPUS, LILACS, Web of Science, CENTRAL (Cochrane Central Register of Controlled Trials), PEDro, CINAHL, SciELO and Google Scholar, published in any language, up to July 31, 2023. Two independent reviewers extracted the data and assessed evidence quality. The risk of bias of the trials was evaluated by the Cochrane tool and evidence quality by GRADE approach. Review Manager software was used to conduct the meta-analyses.

RESULTS

3007 articles were identified in the searches, remaining 33 studies to be read in full, with 11 trials being eligible for this systematic review. The trials included presented low evidence quality for the balance, gait, quality of life and fear of falling. Land-based and aquatic physical therapy exercises improved the outcomes analyzed; however, aquatic physical therapy exercises were more effective in improving balance, gait, quality of life and reducing fear of falling in CDOAs. The meta-analysis showed that engaging in aquatic physical therapy exercises increases the functional reach, through of the anterior displacement of the center of pressure of CDOAs by 6.36cm, compared to land-based physical therapy exercises, assessed by the Functional Reach test: [CI:5.22 to 7.50], (p<0.00001), presenting low quality evidence.

CONCLUSIONS

Aquatic physical therapy exercises are more effective than their land-based counterparts in enhancing balance, gait, quality of life and reducing the fear of falling in CDOAs. However, due to methodological limitations of the trials, this clinical decision remains inconclusive. It is suggested that new trials be conducted with greater methodological rigor, in order to provide high-quality evidence on the use of the aquatic physical therapy exercises to improve the outcomes analyzed in CDOAs.

Video-driven simulation of lower limb mechanical loading during aquatic exercises

Understanding the mechanical demands of an exercise on the musculoskeletal system is crucial to prescribe effective training or therapeutic interventions. Yet, that knowledge is currently limited in water, mostly because of the difficulty in evaluating external resistance. Here I reconcile recent advances in 3D markerless pose and mesh estimation, biomechanical simulations, and hydrodynamic modeling, to predict lower limb mechanical loading during aquatic exercises. Simulations are driven exclusively from a single video. Fluid forces were estimated within 12.5±4.1% of the peak forces determined through computational fluid dynamics analyses, at a speed three orders of magnitude greater. In silico hip and knee resultant joint forces agreed reasonably well with in vivo instrumented implant recordings (R²=0.74) downloaded from the OrthoLoad database, both in magnitude (RMSE =251±125 N) and direction (cosine similarity = 0.92±0.09). Hip flexors, glutes, adductors, and hamstrings were the main contributors to hip joint compressive forces (40.4±12.7%, 25.6±9.7%, 14.2±4.8%, 13.0±8.2%, respectively), while knee compressive forces were mostly produced by the gastrocnemius (39.1±15.9%) and vasti (29.4±13.7%). Unlike dry-land locomotion, non-hip- and non-knee-spanning muscles provided little to no offloading effect via dynamic coupling. This noninvasive method has the potential to standardize the reporting of exercise intensity, inform the design of rehabilitation protocols and improve their reproducibility.

Improvement of Balance, Motor Aspects, and Activities of Daily Living in Parkinson's Disease after a Sequential Multimodal Aquatic- and Land-Based Intervention Program

Parkinson's disease (PD) is a neurodegenerative, with heterogeneous clinical conditions and motor changes that reduce functioning. Postural instability is one of the motor aspects of disease progression, with a potential increase in the risk of falls, consequently affecting the activities of daily living (ADL). The objective of this study was to verify the influence of a multimodal intervention program (MIP) sequentially applied in aquatic- (AEs) and land-based environments (LEs) on balance, postural control, motor activities, and ADL in people with PD. It is an interventional clinical study with patients in stages 1 to 4 in the Hoehn and Yahr scale, assessed with Berg Balance Scale (BBS), Mini-Balance Evaluation System Test (Mini-BESTest), Unified Parkinson's Disease Rating Scale (UPDRS) II and III, Dynamic Gait Index (DGI), and quiet stance (QS) analysis in a force platform. The MIP was conducted sequentially with aquatic- (AIs) and land-based interventions (LIs) for 12 weeks each, twice a week, each session lasting 1 hour, and a 12-week interval between interventions. The comparison analysis was made with Friedman ANOVA, and the multiple comparisons with Wilcoxon signed-rank, Bonferroni correction, and effect size (r). The sample comprised 18 people with PD (66.83 ± 11.74 years). The AI and the full intervention (FI) had a large effect according to BBS. With Mini-BESTest, the LI and FI had a large effect. According to UPDRS II, the MIP improved ADL after LI, with a medium effect, and the motor aspects of UPDRS III improved after LI and FI, with a large effect. DGI was not sensitive in the analyses, with a ceiling effect after FI. No differences were identified in QS analyses. This research identified improved balance, ADL, and motor aspects in people with PD after sequential MIP in AI and LI, indicating that land-based and aquatic interventions are complementary and advantageous to people with PD.

Effects of an Aquatic Physical Exercise Program on Ventilatory Parameters in People with Parkinson’s Disease

Problems in the respiratory system are the main cause of death in Parkinson’s disease (PD). Ventilatory limitations can also be part of a vicious cycle involving physical-functional limitations (e.g., walking difficulties) and the patients’ perception of fatigue. The objective of this study was to analyze the effects of an aquatic physical exercise intervention program on ventilatory parameters, perception of fatigue, and gait capacity in participants with PD. This quasi-experimental study had a single group with repeated measures in four assessments, proposing an aquatic physical exercise intervention program. The inclusion criteria encompassed being in levels 1 to 4 on the Hoehn and Yahr scale and having a medical certificate for the activities. Assessments took place at 3-month intervals between them—the first period was the control, the second following the intervention, and the third period was the follow-up. The intervention had 25 biweekly sessions over 3 months. A total of 13 people (71.3 ± 5.61 years old) participated in the intervention, without significant differences in the control period. Between the intervention assessments, they had statistically significant differences in MIP, MEP, FVC, Tiffeneau index, MVV, and fatigue. The study demonstrated that the aquatic physical exercise intervention was effective for ventilatory outcomes and fatigue in people with PD.

Multicomponent Aquatic Training (MAT) Program for People with Parkinson's Disease: A Protocol for a Controlled Study

Introduction: The complications from Parkinson’s disease (PD) are directly related to decreased muscle function, balance deficits, and independence loss. Practicing aquatic exercises can minimize these symptoms and slow disease progress. Objective: To develop a Multicomponent Aquatic Training (MAT) protocol for people with PD between stages 1 and 4 of the Hoehn and Yahr scale. Methods: The protocol is for a single blind controlled clinical trial. The sample will comprise of people with PD between stages 1 and 4 in Hoehn and Yahr scale, divided into a control group and MAT group (who will participate in the MAT). Musculoskeletal function, functional mobility, and balance will be the primary outcomes of interest, assessed with an isokinetic dynamometer, the Five-Times-Sit-to-Stand test (FTSST), the Timed “Up and Go” test (TUG), the 6-m gait speed test, the Berg Balance Scale (BBS), and a force platform. Quality of life (QOL), activities of daily living (ADL), and motor aspects will be the secondary outcome measures, assessed with the Parkinson’s Disease Questionnaire (PDQ-39) and Unified Parkinson’s Disease Rating Scale (UPDRS), sections II and III. The MAT will be 12 weeks long, with two 50-min sessions per week. The outcome measures will be assessed before and after the interventions. Discussion: This study is expected to establish parameters to prescribe and monitor a MAT program for people with PD in stages 1 to 4 in the Hoehn and Yahr scale, respecting individual progress and assisting the professionals in their procedure with these people.

Evidence-Based Aquatic Therapy Guidelines for Parkinson's Disease: An International Consensus Study

BACKGROUND

Aquatic therapy is one therapy option for people living with Parkinson's disease (PD). However, the optimal prescription, dosage, and delivery remain unclear.

OBJECTIVE

i) To generate consensus statements, ii) to establish evidence-based clinical practice aquatic therapy guidelines for PD.

METHODS

Seventy-three international experts were invited to participate in a 3-step modified Delphi study. Gaps in the aquatic therapy evidence, patient preferences, and stakeholder engagement were considered when developing the initial list of 43-statements identified by the research development group. Practice experts rated each statement on an 11-point Likert scale. Consensus for inclusion was set at a priori of ≥70% of respondents scoring an item ≥7. Two rounds of Delphi questionnaires were completed online, and the expert comments were analyzed using content analysis. An online consensus meeting with an expert subgroup (n = 10) then advised on the guideline's acceptability and debated items until consensus for inclusion was reached.

RESULTS

Fifty experts participated in the Delphi round one (83% response rate) and 45 in round two (90% response rate), representing 15 countries. In round one, 35 statements met the criteria for consensus. Content analysis informed the revised statements in round two, where 12 of the remaining 16 statements met consensus. The final agreed aquatic therapy guidelines include key information about dosage, content, safety, contraindications, and the optimal aquatic therapy delivery throughout the disease course.

CONCLUSION

Stakeholders, including international practice experts, informed a rigorous evidence-based approach to integrate the best available evidence, patient preferences, and practice expertise to inform these guidelines.

The efficacy of aquatic therapy in stroke rehabilitation: A protocol for systematic review and meta-analysis

BACKGROUND

METHODS

This protocol of systematic review and meta-analysis has been drafted under the guidance of the preferred reporting items for systematic reviews and meta-analyses protocols. This study will use the Cochrane Library, Web of Science, PubMed, Embase, Allied and Complementary Medicine Database (AMED), China Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Wanfang Database, and Ongoing Clinical Trials Database. Quality assessment of the included studies was evaluated using the Cochrane risk of bias assessment tool. We performed the meta-analysis by RevMan 5.4 software.

RESULTS

The results of this systematic review and meta-analysis will be published in a peer-reviewed journal.

CONCLUSION

Aquatic therapy may be a valid means for the rehabilitation of people affected by stroke.Open Science Framework registration number: https://doi.org/10.17605/OSF.IO/ZKE3Y10.17605/OSF.IO/8UDV9.

Community aquatic therapy for Parkinson's disease: an international qualitative study

PURPOSE

To explore the opinions of people living with Parkinson's disease about access to and participation in community aquatic therapy.

METHODS

Focus groups and individual interviews were conducted with people living with Parkinson's disease in Ireland (n = 24) and Australia (n = 10). All discussions were audio-recorded, transcribed verbatim, and thematically analysed.

RESULTS

Four main themes were identified. Primarily, participants were optimistic about their reasons for choosing aquatic therapy and found it beneficial to their health and well-being. Optimal components of aquatic therapy identified were access to individually tailored aquatic programs, completed as a minimum once a week, at a moderate to high-intensity level, and guided by a credentialed instructor. Fear was a significant barrier for a small proportion of participants and was linked to water competence, past experiences, and fall risk associated with the aquatic environment. Participants identified a strong need for education and increased awareness about aquatic therapy benefits to promote greater engagement.

CONCLUSION

Aquatic therapy is a popular exercise choice for people with Parkinson's disease, especially in the early to middle disease stages. Considering the views of people living with Parkinson's disease can aid the design and implementation of interventions and future aquatic research internationally.Implications for RehabilitationAquatic therapy is emerging as an effective physiotherapy approach for managing motor and non-motor symptoms in Parkinson's disease.Little is known regarding community-based aquatic therapy programs from the perspectives of people living with Parkinson's disease internationally.People with Parkinson's disease may benefit from timely information about the unique benefits, prerequisites, and local aquatic therapy facilities to promote greater uptake of aquatic programs.Tailored aquatic therapy interventions delivered within a group setting by a credentialed healthcare professional may increase long-term adherence.

Enablers to Exercise Participation in Progressive Supranuclear Palsy: Health Professional Perspectives

Background: People living with progressive supranuclear palsy (PSP) can experience considerable difficulties with movement, walking, balance, and oculomotor control. The role of exercises and physical activities in mitigating the motor and non-motor symptoms of PSP remains uncertain. Aims: The aim of this study was to identify the perspectives and beliefs of health professionals about the benefits, enablers, and barriers to participation in exercise and physical activity across the course of disease progression of PSP. Methods: Qualitative methods, within a phenomenological framework, were used to obtain nursing and allied health professional perspectives and recommendations. Focus group and in-depth interview questions were derived from a systematic review on exercise for PSP. Expert opinions also guided the interviews, which were audio-recorded, transcribed verbatim, and de-identified. Two researchers independently conducted a thematic analysis. Results: Nineteen health professionals participated from the disciplines of nursing, physiotherapy, occupational therapy, and speech pathology. Four main themes emerged: (i) exercise and physical activities are important for living well with PSP; (ii) provision of information about the benefits of exercise and physical activities facilitates uptake; (iii) interdisciplinary teams work together to improve outcomes; and (iv) care partners can assist with the implementation of exercise and physical activities. Conclusion: Health professionals advocated physical therapies for people living with PSP. The expectation is that structured exercises and physical activities can help to optimize health and well-being, enabling people to continue to participate in social roles. The actual merits of such interventions must now be tested in large-scale controlled clinical trials.

The Association Between Cardiovascular Function, Measured as FMD and CVC, and Long-Term Aquatic Exercise in Older Adults (ACELA Study): A Cross-Sectional Study

Introduction

Cardiovascular aging is implicated in the development of cardiovascular disease (CVD). Aquatic exercise is being considered as a co-adjuvant form of rehabilitation, but there is limited evidence for its cardiovascular risk-reduction properties for older people. Our study aimed to address this by exploring the cardiovascular effects of long-term aquatic exercise in older adults in comparison to those who are either inactive or engaged in land-based/mixed training by measurement of micro- and macro-circulation. Flow Mediated Dilatation (FMD) was the primary outcome.

Methods

This was a pragmatic, 4-group, cross-sectional study. Eighty normotensive adults constituted four (n = 20) groups. The Aqua group (aged 63.7 ± 7 years) and Land group (aged 65 ± 6 years) consisted of participants engaged in aquatic and land-based training, respectively. The mixed group (Mix) (aged 66 ± 6 years) consisted of participants engaged in both land-based and aquatic training. Self-reported training consisted of ≥2/week for ≥6 months (mean sessions/week = 4 ± 1, 4 ± 1, and 5 ± 2 for each group, respectively). The sedentary group (Sed) (aged 63 ± 6 years) consisted of people who were sedentary for ≥6 months (mean sessions/week 0 ± 0). The primary outcome was %FMD. Secondary outcomes included raw cutaneous vascular conductance (CVC) and CVC max.

Results

Statistically significant differences (%FMD, raw CVC variables other than baseline) were found between each of the exercise groups (Aqua, Land, Mix) and the sedentary group (Sed) (i.e., 11.2 (4.2) vs. 5.0 (2.3); p < 0.0005, between the Aqua group and Sed group, for %FMD). No specific advantage could be attributed to any one of the exercise groups.

Conclusion

We reported improvements in NO-mediated endothelial function at micro- and macro-circulatory levels, observing no differences between exercise modes. Our findings provide evidence for the role of aquatic exercise as a "shield" against CVD in older populations.

Aquatic Therapy in Contemporary Neurorehabilitation: An Update

Aquatic therapy has been used extensively in a number of neurologic diseases and pathologies. This review describes disease-specific rehabilitative applications for this population. Recent research has offered scientific support for use in common neurological diseases that are part of rehabilitative practice, and very recent findings may create even firmer support for its use in these as well as other conditions. Stroke, Parkinsonism, and multiple sclerosis are areas that have recently received a significant number of published studies. Dementia is another area that has been more recently studied and received basic science support. Cerebral palsy has also had recent supportive evidence published. Available literature is reviewed to create a more evidence-based support for the use of aquatic therapy in neurorehabilitation.

Muscle Activation and Distribution during Four Test/Functional Tasks: A Comparison between Dry-Land and Aquatic Environments for Healthy Older and Young Adults

BACKGROUND

The use of rehabilitation protocols carried out in water has been progressively increasing due to the favorable physical properties of the water. Electromyography allows one to register muscle activity even under water.

AIM

To compare muscle activity between two groups (healthy young adults (HYA) and healthy older adults (HOA)) in two different environments (dry land and aquatic) using surface electromyography during the execution of four different test/functional movements.

METHODS

Analytical cross-sectional study. HYA and HOA carried out four functional tasks (Step Up and Down, Sit To Stand test, Gait Initiation and Turns During Gait) in two different environments (dry land and aquatic). Absolute and relative muscle activation was compared between each group and between each environment. In addition, the stability of the measured was calculated through a test-retest (ICC 2:1).

RESULTS

Within the same environment there were significant differences between young and older adults in three of the four functional tasks. In contrast, in the gait initiation, hardly any significant differences were found between the two groups analysed, except for the soleus and the anterior tibial. Measurement stability ranged from good to excellent.

CONCLUSIONS

Level of the musculature involvement presents an entirely different distribution when the test/functional task is performed on dry land or in water. There are differences both in the relative activation of the musculature and in the distribution of the partition of the muscles comparing older and young adults within the same environment.
