Hydrotherapy versus conventional land-based exercise for the management of patients with osteoarthritis of the knee: a randomized clinical trial

Aquatic physical therapy as a treatment modality in healthcare for non-institutionalized elderly persons: a systematic review

ABSTRACT Objective: To review scientific literature pertaining to aquatic physical therapy in the elderly and institutionalized population. Methods: A qualitative systematic review of electronic databases MEDLINE and LILACS, with the topic index terms: “hydrotherapy,” “homes for the aged or residential facilities,” and “aged. In light of the lack of studies carried out on the institutionalized population, we opted for reviewing literature on the effectiveness of this modality of physical therapy treatment on the non-institutionalized elderly population in order to produce knowledge that can be critically analyzed according to its potential applicability for the institutionalized population. The methodological quality of the studies was assessed using the Delphi listing. Results: Of the 27 studies analyzed by their abstracts, 10 studies were excluded since they did not correspond to the eligibility criteria. We analyzed the subject characteristics of each study, as well as the quality of the methods (good methodological quality in 47% of the studies), the result measurements considered, the intervention strategies, the sites where they took place, and the professionals involved (76% by physical therapists). Conclusion: Although a large part of the studies demonstrated good results with aquatic physical therapy practice, none of them had been applied on long-stay institution for the elderly. Therefore, more studies are needed in this area for a model of assistance to long-stay institution for the elderly to be proposed.

Nonsurgical Management of Severe Osteonecrosis of the Knee in an HIV-Positive Patient: A Case Report

Due to the life-prolonging effects of combination antiretroviral therapy, many people with HIV are living longer. However, this enhanced longevity is often mirrored by increased disability resulting from HIV and/or the adverse effects of medication. Management of HIV-positive patients is further complicated by comorbidities related to aging, including bone and joint disorders. In this paper, we describe the nonsurgical management of an HIV-positive patient with premature onset of severe osteonecrosis of the knee. A 50-year-old man who had been HIV-positive for 16 years and on combination antiretroviral therapy for 11 years presented to his family physician with extreme discomfort in his right knee. He was diagnosed with osteonecrosis of the right knee, but resisted total knee arthroplasty because of potential complications under anesthesia related to comorbid advanced liver disease. Instead, a successful combination of non-surgical management strategies was employed by the patient and his health care team.

Effects of exercise on functional aerobic capacity in lower limb osteoarthritis: a systematic review

Osteoarthritis (OA) is a degenerative joint disease. The reduced aerobic capacity of patients with lower limb osteoarthritis affects their independence in performing everyday activities. The purpose of this systematic review was to summarize evidence for the effectiveness and structure of exercise programs on functional aerobic capacity (ability to perform activities of daily living that require sustained aerobic metabolism) in patients with hip and knee osteoarthritis. A computerized search was made of seven databases. Effect sizes (ES) and 95% confidence intervals (CI) were calculated, and the heterogeneity of the studies was assessed using Cochran's Q statistic applied to the ES means. The 20 studies that satisfied the inclusion criteria were selected for analysis. These studies were grouped into five categories according to the characteristics of the exercise program: land-based interventions (strength programs, tai chi, aerobic programs, mixed exercise programs) and aquatic intervention (hydrotherapy). The functional aerobic capacity improved in tai chi programs (ES=0.66; 95% CI, 0.23-1.09), aerobic programs (ES=0.90; 95% CI, 0.70-1.10), and mixed programs (ES=0.47; 95% CI, -0.38-0.39). The conclusions were: (i) despite recommendations for the use of exercise programs for aerobic fitness in patients with hip and knee osteoarthritis, few randomized clinical trials have been conducted; (ii) the structure of the exercise programs (program content and duration, and session frequency and duration) is very heterogeneous; (iii) overall, exercise programs based on tai chi, aerobic, and mixed exercise seem to give better results than hydrotherapy programs, but without the differences being altogether clear.

Measuring patient satisfaction with exercise therapy for knee osteoarthritis: evaluating the utility of the physiotherapy outpatient survey

OBJECTIVES

To assess patient satisfaction with exercise for knee osteoarthritis (OA).

METHODS

A convenience sample of 27 patients recruited to a randomized controlled trial (RCT) comparing open kinetic chain and closed kinetic chain exercises for knee OA were reassessed at nine months post-randomization. Clinical outcomes included self-report and physical performance measures of function and pain severity. Patients also completed the Physiotherapy Outpatient Survey (POPS), which is a multi-dimensional measure of patient satisfaction with physiotherapy.

RESULTS

There was no significant difference in satisfaction between the two intervention groups. Overall mean satisfaction for the entire cohort was 4.07 of a maximum score of 5 (standard deviation (SD) = 0.52). Lower levels of satisfaction with outcome (mean = 3.56, SD = 0.8) were reported compared with other domains of expectations, communication, organization and the therapist (mean = 3.79-4.49; SDs = 0.42-0.92). Both intervention groups improved from baseline on clinical outcomes of pain, self-report function and walking distance, with no significant differences between the two groups.

CONCLUSIONS

High levels of satisfaction were reported in this subsample of knee OA patients participating in an RCT evaluating the effects of different exercise approaches for knee OA. Satisfaction varied depending on the satisfaction domain, with lower satisfaction with outcome compared with other aspects of care. The POPS questionnaire can be used to measure the multi-dimensional aspects of satisfaction with physiotherapy.

A proposal for a worldwide definition of health resort medicine, balneology, medical hydrology and climatology

Health Resort Medicine, Balneology, Medical Hydrology and Climatology are not fully recognised as independent medical specialties at a global international level. Analysing the reasons, we can identify both external (from outside the field) and internal (from inside the field) factors. External arguments include, e.g. the lack of scientific evidence, the fact that Balneotherapy and Climatotherapy is not used in all countries, and the fact that Health Resort Medicine, Balneology, Medical Hydrology and Climatology focus only on single methods and do not have a comprehensive concept. Implicit barriers are the lack of international accepted terms in the field, the restriction of being allowed to practice the activities only in specific settings, and the trend to use Balneotherapy mainly for wellness concepts. Especially the implicit barriers should be subject to intense discussions among scientists and specialists. This paper suggests one option to tackle the problem of implicit barriers by making a proposal for a structure and description of the medical field, and to provide some commonly acceptable descriptions of content and terminology. The medical area can be defined as "medicine in health resorts" (or "health resort medicine"). Health resort medicine includes "all medical activities originated and derived in health resorts based on scientific evidence aiming at health promotion, prevention, therapy and rehabilitation". Core elements of health resort interventions in health resorts are balneotherapy, hydrotherapy, and climatotherapy. Health resort medicine can be used for health promotion, prevention, treatment, and rehabilitation. The use of natural mineral waters, gases and peloids in many countries is called balneotherapy, but other (equivalent) terms exist. Substances used for balneotherapy are medical mineral waters, medical peloids, and natural gases (bathing, drinking, inhalation, etc.). The use of plain water (tap water) for therapy is called hydrotherapy, and the use of climatic factors for therapy is called climatotherapy. Reflecting the effects of health resort medicine, it is important to take other environmental factors into account. These can be classified within the framework of the ICF (International Classification of Functioning, Disability and Health). Examples include receiving health care by specialised doctors, being well educated (ICF-domain: e355), having an environment supporting social contacts (family, peer groups) (cf. ICF-domains: d740, d760), facilities for recreation, cultural activities, leisure and sports (cf. ICF-domain: d920), access to a health-promoting atmosphere and an environment close to nature (cf. ICF-domain: e210). The scientific field dealing with health resort medicine is called health resort sciences. It includes the medical sciences, psychology, social sciences, technical sciences, chemistry, physics, geography, jurisprudence, etc. Finally, this paper proposes a systematic international discussion of descriptions in the field of Health Resort Medicine, Balneology, Medical Hydrology and Climatology, and discusses short descriptive terms with the goal of achieving internationally accepted distinct terms. This task should be done via a structured consensus process and is of major importance for the publication of scientific results as well as for systematic reviews and meta-analyses.

Exercise for people with hip or knee osteoarthritis: a comparison of land-based and aquatic interventions

Expert opinion considers the referral of people with osteoarthritis (OA) for physiotherapy to be a core component of managing the functional disability and pain of the disease. Clinical guidelines for the physiotherapy management of people with OA focus on three main areas: exercise, pain relief, and specific manual therapy techniques. Land-based group and individual physiotherapy exercise programs, as well as manual therapy, have demonstrated a distinct benefit in favor of physiotherapy intervention. Similarly, both general and specific aquatic physiotherapy exercise programs have shown positive outcomes for people with OA. This review will focus primarily on therapeutic exercise to improve strength and fitness and reduce pain in people with hip or knee OA. An overview of the principles of hydrodynamics relevant to aquatic exercise is also included to facilitate an understanding of effective aquatic exercise programs. The issue of compliance with exercise programs will also be discussed. Clinicians will, therefore, gain an understanding of the benefits of land-based and aquatic exercise for people with OA.

Aquatic versus land-based exercises as early functional rehabilitation for elite athletes with acute lower extremity ligament injury: a pilot study

OBJECTIVE

To compare outcomes between aquatic and land-based exercises during early-phase recovery from acute lower extremity ligament injuries in elite athletes.

DESIGN

A single-blinded, covariate adaptive randomized, controlled study.

SETTING

National training center for elite athletes.

PARTICIPANTS

Twenty-two athletes with isolated grade I or II ligament injury in ankles or knees were randomized into either an aquatic or land-based exercise group.

INTERVENTIONS

Early functional rehabilitation program (ranging, strengthening, proprioceptive training, and functional exercises) was performed in both groups. All exercises were identical except for the training environment.

MAIN OUTCOME MEASUREMENTS

Data were collected at baseline and at 2 and 4 weeks using a visual analog scale (VAS) for pain; static stability (overall stability index [OSI] level 5 and 3); dynamic stability (TCT), and percentage single-limb support time (%SLST).

RESULTS

Both groups showed decreases in VAS, OSI 5 and 3, and TCT, with a concomitant increase in %SLST at 2 and 4 weeks (P < .05). No significant differences were detected between the 2 groups in any of the outcome measures. However, the line graphs for VAS, OSI 3, TCT, and %SLST in the aquatic exercise group were steeper than those in the land-based exercise group indicating significant group by time interactions (P < .05). These data indicate that the aquatic exercise group improved more rapidly than the land-based exercise group.

CONCLUSIONS

For elite athletes with acute ligament sprains in the lower limb, aquatic exercises may provide advantages over standard land-based therapy for rapid return to athletic activities. Consequently, aquatic exercise could be recommended for the initial phase of a rehabilitation program.

Naturopathy and the primary care practice

Naturopathy is a distinct type of primary care medicine that blends age-old healing traditions with scientific advances and current research. Naturopathy is guided by a unique set of principles that recognize the body's innate healing capacity, emphasize disease prevention, and encourage individual responsibility to obtain optimal health. Naturopathic treatment modalities include diet and clinical nutrition, behavioral change, hydrotherapy, homeopathy, botanical medicine, physical medicine, pharmaceuticals, and minor surgery. Naturopathic physicians (NDs) are trained as primary care physicians in 4-year, accredited doctoral-level naturopathic medical schools. At present, there are 15 US states, 2 US territories, and several provinces in Canada, Australia, and New Zealand that recognize licensure for NDs.

Psychosocial factors and the pain experience of osteoarthritis patients: new findings and new directions

PURPOSE OF REVIEW

The present paper reviews recent psychosocial research in the area of osteoarthritis pain. First, the review highlights studies of psychosocial factors that can influence osteoarthritis pain. Next, research testing the efficacy of psychosocial treatments for osteoarthritis pain is summarized.

RECENT FINDINGS

Recent studies suggest that asking osteoarthritis patients to recall pain experiences may not be as accurate as having them keep daily pain records. New studies also support the notion that fatigue and increased weight are linked to higher osteoarthritis pain. Osteoarthritis patients who report higher levels of depression are more prone to report increased osteoarthritis pain. New studies also indicate that social factors such as ethnic background, ability to communicate pain to others, and participation in social activities can influence osteoarthritis pain and disability. Cognitions about pain (i.e. pain catastrophizing, acceptance, self-efficacy for pain) also have been found to relate to pain in patients with osteoarthritis. Recent, randomized controlled studies suggest that psychosocial interventions (i.e. self-management programs, exercise) can decrease osteoarthritis pain and disability.

SUMMARY

Several psychosocial variables have been suggested as influencing osteoarthritis pain and disability. There is evidence that psychosocial interventions may decrease osteoarthritis pain and disability.

A comparison of Kneipp hydrotherapy with conventional physiotherapy in the treatment of osteoarthritis of the hip or knee: protocol of a prospective randomised controlled clinical trial

BACKGROUND

The increasing age of the population, especially in the western world, means that the prevalence of osteoarthritis is also increasing, with corresponding socioeconomic consequences. Although there is no curative intervention at present, in accordance with US and European guidelines, pharmacotherapeutic and non-pharmacological approaches aim at pain control and the reduction of functional restriction.It has been established that hydrotherapy for osteoarthritis of the hip or knee joint using serial cold and warm water stimulation not only improves the range of movement but also reduces pain significantly and increases quality of life over a period of up to three months. Weight reduction is important for patients with osteoarthritis of the hip or knee. In addition, conventional physiotherapy and exercise therapy have both been shown, at a high level of evidence, to be cost-effective and to have long-term benefits for pain relief, movement in the affected joint, and patient quality of life.

METHODS/DESIGN

The study design consists of a prospective randomised controlled three-armed clinical trial, which will be carried out at a specialist clinic for integrative medicine, to investigate the clinical effects of hydrotherapy on osteoarthritis of the knee or hip joint, in comparison with conventional physiotherapy.One hundred and eighty patients diagnosed with osteoarthritis of hip or knee will be randomly assigned to one of three intervention groups: hydrotherapy, physiotherapy, and both physiotherapy and hydrotherapy of the affected joint. In the first group, patients will receive Kneipp hydrotherapy daily, with water applied in the form of alternate cold and warm thigh affusions (alternating cold and warm water stimulation is particularly relevant to the knee and hip regions).Patients in the second group will receive physiotherapy of the hip or knee joint three times a week. Patients in the physiotherapy-hydrotherapy combination group will receive both joint-specific physiotherapy three times a week and alternate cold and warm thigh affusions every day. Follow-up assessments will be on three levels: clinical assessment by the investigator; subjective patient assessment consisting of a patient diary, and questionnaires on admission and at the end of the treatment phase; and a final telephone assessment by the external evaluation centre. Assessments will be made at baseline, after two weeks of inpatient treatment, and finally after a further ten weeks of follow-up. The primary outcome measure will be pain intensity of the affected joint in the course of inpatient treatment, judged by the patient and the investigator. Secondary outcomes include health-related quality of life and joint-specific pain and mobility in the course of the study. Statistical analysis of the results will be on an intention-to-treat basis.

CONCLUSION

This study methodology has been conceived according to the standards of the CONSORT recommendations. The results will contribute to establishing hydrotherapy as a non-invasive, non-interventional, reasonably priced, therapeutic option with few side effects, in the concomitant treatment of osteoarthritis of the hip or knee.

Land-based versus pool-based exercise for people awaiting joint replacement surgery of the hip or knee: results of a randomized controlled trial

OBJECTIVE

To compare the preoperative effects of multidimensional land-based and pool-based exercise programs for people awaiting joint replacement surgery of the hip or knee.

DESIGN

Randomized, single-blind, before-after trial.

SETTING

Physiotherapy gymnasium and hydrotherapy pool.

PARTICIPANTS

Patients awaiting elective hip or knee joint replacement surgery.

INTERVENTIONS

Land-based (n=40) or pool-based exercise program (n=42). Each 6-week program included an education session, twice-weekly exercise classes, and an occupational therapy home assessment.

MAIN OUTCOME MEASURES

Participants were assessed immediately before and after the 6-week intervention, then 8 weeks later. Primary outcomes were pain and self-reported function (Western Ontario and McMaster Universities Osteoarthritis Index) and patient global assessment. Secondary outcomes were performance-based measures (timed walk and chair stand) and psychosocial status (Medical Outcomes Study 36-Item Short-Form Health Survey mental component score). Pain was also measured before and after each exercise class on a 7-point verbal rating scale.

RESULTS

Although both interventions were effective in reducing pain and improving function, there were no postintervention differences between the groups for the primary and secondary outcomes. However, the pool-based group had less pain immediately after the exercise classes.

CONCLUSIONS

While our multidimensional exercise-based interventions appeared to be effective in reducing disability in those awaiting joint replacement surgery of the hip or knee, there were no large differences in the postintervention effects of the interventions. However, pool-based exercise appeared to have a more favorable effect on pain immediately after the exercise classes.

Reliability of performance-based measures in people awaiting joint replacement surgery of the hip or knee

BACKGROUND AND PURPOSE

Understanding the reliability of selected measurement tools is a prerequisite to understanding the effects of clinical interventions. The aim of this investigation was to determine the reliability of the 50-Foot Timed Walk (50 FTW) and 30-second Chair Stand Test (30 CST) in subjects awaiting joint replacement surgery of the hip or knee.

METHODS

Eighty-two subjects participating in a 6-week exercise programme were assessed at baseline, 7 weeks and 15 weeks. Four trials of the 50 FTW and two trials of the 30 CST were completed at each assessment. Eleven trained assessors completed the assessments.

RESULTS

Intra-class correlations were consistently high for the 50 FTW and 30 CST at all assessments. At the baseline assessment, trial 1 was found to be significantly different from subsequent trials for both the 50 FTW and 30 CST. This effect was not evident at the 7-week and 15-week assessments. At the baseline assessment, scores for the 50 FTW became stable after the first trial. Estimates of minimum detectable change indicated that participants needed to change by more than 3.08 seconds and 1.64 stands to be 90% confident that a real change had occurred for the 50 FTW and 30 CST, respectively.

CONCLUSION

The 50 FTW and 30 CST can be reliable measures of physical performance. However, because we found a practice effect at the baseline assessment, a practice trial should be allowed before data collection begins. Because only two trials of the 30 CST were completed, further research is required to confirm whether scores at the initial assessment become stable on repeated testing.

Muscle and exercise in the prevention and management of knee osteoarthritis: an internal medicine specialist's guide

This article outlines the influence of muscle activity on knee-joint loading, describes the deficits in muscle function observed in people with knee osteoarthritis, and summarizes available evidence pertaining to the role of muscle in the development and progression of knee osteoarthritis. The article focuses on whether muscle deficits can be modified in knee osteoarthritis and whether improvements in muscle function lead to improved symptoms and joint structure. This article concludes with a discussion of exercise prescription for muscle rehabilitation in knee osteoarthritis.
