A pilot study to evaluate the effects of floatation spa treatment on patients with osteoarthritis

A patient reported outcome measure in homeopathic clinical practice for long-term conditions

BACKGROUND

This study was initiated as part of a quality improvement audit process to create standards around goal setting with our patients to understand and improve outcomes of homeopathic treatment.

METHOD

We used the Measure Yourself Medical Outcome Profile (MYMOP2) as a tool to assist clinicians in setting the treatment goals across a wide range of diagnoses and other complaints in routine clinical practice at the Bristol Homeopathic Hospital. The data collected from the MYMOP2 is of significance in its own right and the results are now reported in this paper.

RESULTS

A total of 198 patients with a wide range of complaints attended one to five consultations with 20 homeopathic doctors. Diagnostic categories were most commonly neoplasms (16.7%), psychological (13.9%) and genitourinary complaints (12.3%), with 66.7% suffering from these problems for at least one year. The three symptoms that bothered patients the most were pain, mental symptoms and tiredness/fatigue. A paired-samples t-test using an intention-to-treat analysis showed that the MYMOP2 profile score improved from 4.25 (IQR 3.50-5.00), with a mean change of 1.24 (95% CI 1.04, 1.44) from the first to the last consultation (p<0.001). Results were statistically significant both for completers (n=91) (p<0.001) and non-completers (n=107) (p<0.001) using last-observation-carried-forward, although completers did better than non-completers (p<0.001). The overall clinical significance of improvements was at least moderate. A repeated measures ANOVA test also showed statistically significant improvements (p<0.001).

CONCLUSION

The MYMOP2 results add to a growing body of observational data which demonstrates that when patients with long term conditions come under homeopathic care their presenting symptoms and wellbeing often improve. Offering a low cost high impact intervention to extend the range of choice to patients and to support self-care could be an important part of the NHS.

Aquatic exercise for the treatment of knee and hip osteoarthritis

BACKGROUND

Osteoarthritis is a chronic disease characterized by joint pain, tenderness, and limitation of movement. At present, no cure is available. Thus only treatment of the person's symptoms and treatment to prevent further development of the disease are possible. Clinical trials indicate that aquatic exercise may have advantages for people with osteoarthritis. This is an update of a published Cochrane review.

OBJECTIVES

To evaluate the effects of aquatic exercise for people with knee or hip osteoarthritis, or both, compared to no intervention.

SEARCH METHODS

We searched the following databases up to 28 April 2015: the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library Issue 1, 2014), MEDLINE (from 1949), EMBASE (from 1980), CINAHL (from 1982), PEDro (Physiotherapy Evidence Database), and Web of Science (from 1945). There was no language restriction.

SELECTION CRITERIA

Randomized controlled clinical trials of aquatic exercise compared to a control group (e.g. usual care, education, social attention, telephone call, waiting list for surgery) of participants with knee or hip osteoarthritis.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials for inclusion, extracted data and assessed risk of bias of the included trials. We analysed the pooled results using standardized mean difference (SMD) values.

MAIN RESULTS

Nine new trials met the inclusion criteria and we excluded two earlier included trials. Thus the number of participants increased from 800 to 1190 and the number of included trials increased from six to 13. Most participants were female (75%), with an average age of 68 years and a body mass index (BMI) of 29.4. Osteoarthritis duration was 6.7 years, with a great variation of the included participants. The mean aquatic exercise duration was 12 weeks. We found 12 trials at low to unclear risk of bias for all domains except blinding of participants and personnel. They showed that aquatic exercise caused a small short term improvement compared to control in pain (SMD -0.31, 95% CI -0.47 to -0.15; 12 trials, 1076 participants) and disability (SMD -0.32, 95% CI -0.47 to -0.17; 12 trials, 1059 participants). Ten trials showed a small effect on quality of life (QoL) (SMD -0.25, 95% CI -0.49 to -0.01; 10 trials, 971 participants). These effects on pain and disability correspond to a five point lower (95% CI three to eight points lower) score on mean pain and mean disability compared to the control group (scale 0 to 100), and a seven point higher (95% CI 0 to 13 points higher) score on mean QoL compared with control group (scale 0 to 100). No included trials performed a radiographic evaluation. No serious adverse events were reported in the included trials with relation to aquatic exercise.

AUTHORS' CONCLUSIONS

There is moderate quality evidence that aquatic exercise may have small, short-term, and clinically relevant effects on patient-reported pain, disability, and QoL in people with knee and hip OA. The conclusions of this review update does not change those of the previous published version of this Cochrane review.

Balneotherapy (or spa therapy) for rheumatoid arthritis

BACKGROUND

No cure for rheumatoid arthritis (RA) is known at present, so treatment often focuses on management of symptoms such as pain, stiffness and mobility. Treatment options include pharmacological interventions, physical therapy treatments and balneotherapy. Balneotherapy is defined as bathing in natural mineral or thermal waters (e.g. mineral baths, sulphur baths, Dead Sea baths), using mudpacks or doing both. Despite its popularity, reported scientific evidence for the effectiveness or efficacy of balneotherapy is sparse. This review, which evaluates the effects of balneotherapy in patients with RA, is an update of a Cochrane review first published in 2003 and updated in 2008.

OBJECTIVES

To perform a systematic review on the benefits and harms of balneotherapy in patients with RA in terms of pain, improvement, disability, tender joints, swollen joints and adverse events.

SEARCH METHODS

We searched the Cochrane 'Rehabilitation and Related Therapies' Field Register (to December 2014), the Cochrane Central Register of Controlled Trials (2014, Issue 1), MEDLIINE (1950 to December 2014), EMBASE (1988 to December 2014), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to December 2014), the Allied and Complementary Medicine Database (AMED) (1985 to December 2014), PsycINFO (1806 to December 2014) and the Physiotherapy Evidence Database (PEDro). We applied no language restrictions; however, studies not reported in English, Dutch, Danish, Swedish, Norwegian, German or French are awaiting assessment. We also searched the World Health Organization (WHO) International Clinical Trials Registry Platform for ongoing and recently completed trials.

SELECTION CRITERIA

Studies were eligible if they were randomised controlled trials (RCTs) consisting of participants with definitive or classical RA as defined by the American Rheumatism Association (ARA) criteria of 1958, the ARA/American College of Rheumatology (ACR) criteria of 1988 or the ACR/European League Against Rheumatism (EULAR) criteria of 2010, or by studies using the criteria of Steinbrocker.Balneotherapy had to be the intervention under study, and had to be compared with another intervention or with no intervention.The World Health Organization (WHO) and the International League Against Rheumatism (ILAR) determined in 1992 a core set of eight endpoints in clinical trials concerning patients with RA. We considered pain, improvement, disability, tender joints, swollen joints and adverse events among the main outcome measures. We excluded studies when only laboratory variables were reported as outcome measures.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials, performed data extraction and assessed risk of bias. We resolved disagreements by consensus and, if necessary, by third party adjudication.

MAIN RESULTS

This review includes two new studies and a total of nine studies involving 579 participants. Unfortunately, most studies showed an unclear risk of bias in most domains. Four out of nine studies did not contribute to the analysis, as they presented no data.One study involving 45 participants with hand RA compared mudpacks versus placebo. We found no statistically significant differences in terms of pain on a 0 to 100-mm visual analogue scale (VAS) (mean difference (MD) 0.50, 95% confidence interval (CI) -0.84 to 1.84), improvement (risk ratio (RR) 0.96, 95% CI 0.54 to 1.70) or number of swollen joints on a scale from 0 to 28 (MD 0.60, 95% CI -0.90 to 2.10) (very low level of evidence). We found a very low level of evidence of reduction in the number of tender joints on a scale from 0 to 28 (MD -4.60, 95% CI -8.72 to -0.48; 16% absolute difference). We reported no physical disability and presented no data on withdrawals due to adverse events or on serious adverse events.Two studies involving 194 participants with RA evaluated the effectiveness of additional radon in carbon dioxide baths. We found no statistically significant differences between groups for all outcomes at three-month follow-up (low to moderate level of evidence). We noted some benefit of additional radon at six months in terms of pain frequency (RR 0.6, 95% CI 0.4 to 0.9; 31% reduction; improvement in one or more points (categories) on a 4-point scale; moderate level of evidence) and 9.6% reduction in pain intensity on a 0 to 100-mm VAS (MD 9.6 mm, 95% CI 1.6 to 17.6; moderate level of evidence). We also observed some benefit in one study including 60 participants in terms of improvement in one or more categories based on a 4-point scale (RR 2.3, 95% CI 1.1 to 4.7; 30% absolute difference; low level of evidence). Study authors did not report physical disability, tender joints, swollen joints, withdrawals due to adverse events or serious adverse events.One study involving 148 participants with RA compared balneotherapy (seated immersion) versus hydrotherapy (exercises in water), land exercises or relaxation therapy. We found no statistically significant differences in pain on the McGill Questionnaire or in physical disability (very low level of evidence) between balneotherapy and the other interventions. No data on improvement, tender joints, swollen joints, withdrawals due to adverse events or serious adverse events were presented.One study involving 57 participants with RA evaluated the effectiveness of mineral baths (balneotherapy) versus Cyclosporin A. We found no statistically significant differences in pain intensity on a 0 to 100-mm VAS (MD 9.64, 95% CI -1.66 to 20.94; low level of evidence) at 8 weeks (absolute difference 10%). We found some benefit of balneotherapy in overall improvement on a 5-point scale at eight weeks of 54% (RR 2.35, 95% CI 1.44 to 3.83). We found no statistically significant differences (low level of evidence) in the number of swollen joints, but some benefit of Cyclosporin A in the number of tender joints (MD 8.9, 95% CI 3.8 to 14; very low level of evidence). Physical disability, withdrawals due to adverse events and serious adverse events were not reported.

AUTHORS' CONCLUSIONS

Overall evidence is insufficient to show that balneotherapy is more effective than no treatment, that one type of bath is more effective than another or that one type of bath is more effective than mudpacks, exercise or relaxation therapy.

Using Chinese version of MYMOP in Chinese medicine evaluation: validity, responsiveness and minimally important change

Background

Measure Yourself Medical Outcome Profile (MYMOP) is a patient generated outcome instrument applicable in the evaluation of both allopathic and complementary medicine treatment. This study aims to adapt MYMOP into Chinese, and to assess its validity, responsiveness and minimally important change values in a sample of patients using Chinese medicine (CM) services.

Methods

A Chinese version of MYMOP (CMYMOP) is developed by forward-backward-forward translation strategy, expert panel assessment and pilot testing amongst patients. 272 patients aged 18 or above with subjective symptoms in the past 2 weeks were recruited at a CM clinic, and were invited to complete a set of questionnaire containing CMYMOP and SF-36. Follow ups were performed at 2^nd and 4^th week after consultation, using the same set of questionnaire plus a global rating of change question. Criterion validity of CMYMOP was assessed by its correlation with SF-36 at baseline, and responsiveness was evaluated by calculating the Cohen effect size (ES) of change at two follow ups. Minimally important difference (MID) values were estimated via anchor based method, while minimally detectable difference (MDC) figures were calculated by distribution based method.

Results

Criterion validity of CMYMOP was demonstrated by negative correlation between CMYMOP Profile scores and all SF-36 domain and summary scores at baseline. For responsiveness between baseline and 4^th week follow up, ES of CMYMOP Symptom 1, Activity and Profile reached the moderate change threshold (ES>0.5), while Symptom 2 and Wellbeing reached the weak change threshold (ES>0.2). None of the SF-36 scores reached the moderate change threshold, implying CMYMOP's stronger responsiveness in CM setting. At 2^nd week follow up, MID values for Symptom 1, Symptom 2, Wellbeing and Profile items were 0.894, 0.580, 0.263 and 0.516 respectively. For Activity item, MDC figure of 0.808 was adopted to estimate MID.

Conclusions

The findings support the validity and responsiveness of CMYMOP for capturing patient centred clinical changes within 2 weeks in a CM clinical setting. Further researches are warranted (1) to estimate Activity item MID, (2) to assess the test-retest reliability of CMYMOP, and (3) to perform further MID evaluation using multiple, item specific anchor questions.

Developing a self-report outcome measure for complementary and alternative medicine

OBJECTIVE

Our objective was to develop a pilot measure of subjective outcomes of complementary and alternative medicine (CAM). Current options for assessing subjective outcomes in CAM are either too burdensome or fail to represent diverse outcomes. A single measure specifying common, patient-reported outcomes of CAM would be of value.

DESIGN

We conducted a three-phase instrument development study. In phase I, 30 CAM-receiving patients and 12 CAM practitioners completed a battery of standardized measures. Participants identified those standardized items relevant to CAM outcome and suggested additional outcome issues. In phase II, 20 CAM-receiving patients completed a Q-sort to determine which items from phase I were most relevant to CAM outcome. In phase III, five experts reviewed the items from phase II for content validity.

SETTING

An integrative medicine clinic at a private, Midwest US hospital.

PARTICIPANTS

CAM patients, practitioners, and researchers and an outcomes measurement specialist.

RESULTS

In phase I, 30 standardized items were judged relevant to CAM outcome, and 8 additional items were suggested. In phase II, 29 of the 38 phase I items were deemed at least "moderately relevant" to CAM outcome. In phase III, experts added 15 items, dropped 9 items, and altered 3 items. The 35 resulting items were classified into content domains, forming a testable, pilot version of the instrument.

Aquatic exercise for the treatment of knee and hip osteoarthritis

BACKGROUND

Clinical experience indicates that aquatic exercise may have advantages for osteoarthritis patients.

OBJECTIVES

To compare the effectiveness and safety of aquatic-exercise interventions in the treatment of knee and hip osteoarthritis.

SEARCH STRATEGY

We searched MEDLINE from 1949, EMBASE from 1980, CENTRAL (Issue 2, 2006), CINAHL from 1982, Web of Science from 1945, all up to May 2006. There was no language restriction.

SELECTION CRITERIA

Randomised controlled trials or quasi-randomised clinical trials.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials for inclusion, assessed the internal validity of included trials and extracted data. Pooled results were analyzed using standardized mean differences (SMD).

MAIN RESULTS

There is a lack of high-quality studies in this area. In total, six trials (800 participants) were included. At the end of treatment for combined knee and hip osteoarthritis, there was a small-to-moderate effect on function (SMD 0.26, 95% confidence interval (CI) 0.11 to 0.42) and a small-to-moderate effect on quality of life (SMD 0.32, 95% CI 0.03 to 0.61). A minor effect of a 3% absolute reduction (0.6 fewer points on a 0 to 20 scale) and 6.6% relative reduction from baseline was found for pain. There was no evidence of effect on walking ability or stiffness immediately after end of treatment. No evidence of effect on pain, function or quality of life were observed on the one trial including participants with hip osteoarthritis alone. Only one trial was identified including knee osteoarthritis alone, comparing aquatic exercise with land-based exercise. Immediately after treatment, there was a large effect on pain (SMD 0.86, 95%CI 0.25 to 1.47; 22% relative percent improvement), but no evidence of effect on stiffness or walking ability. Only two studies reported adverse effects, that is, the interventions did not increase self-reported pain or symptom scores. No radiographic evaluation was performed in any of the included studies.

AUTHORS' CONCLUSIONS

Aquatic exercise appears to have some beneficial short-term effects for patients with hip and/or knee OA while no long-term effects have been documented. Based on this, one may consider using aquatic exercise as the first part of a longer exercise programme for osteoarthritis patients. The controlled and randomised studies in this area are still too few to give further recommendations on how to apply the therapy, and studies of clearly defined patient groups with long-term outcomes are needed to decide on the further use of this therapy in the treatment of osteoarthritis.

Balneotherapy for osteoarthritis

BACKGROUND

Balneotherapy (or spa therapy, mineral baths) for patients with arthritis is one of the oldest forms of therapy. One of the aims of balneotherapy is to soothe the pain and as a consequence to relieve patients' suffering and make them feel well. In this update we included one extra study.

OBJECTIVES

To assess the effectiveness of balneotherapy for patients with osteoarthritis (OA).

SEARCH STRATEGY

We searched the following databases up to October 2006: EMBASE, PubMed, the Cochrane 'Rehabilitation and Related Therapies' Field database, PEDro, CENTRAL (Issue 3, 2006) and performed reference checking and communicated with authors to retrieve eligible studies.

SELECTION CRITERIA

Randomised controlled trials (RCT) comparing balneotherapy with any intervention or no intervention. At least 90% of the patient population had to be diagnosed with OA.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed quality and extracted data. Disagreements were solved by consensus. In the event of clinical heterogeneity or lack of data we refrained from statistical pooling.

MAIN RESULTS

Seven trials (498 patients) were included in this review. Two studies compared spa-treatment with no treatment. One study evaluated baths as an add-on treatment to home exercises and another compared thermal water from Cserkeszölö with tap water (placebo). Three studies evaluated sulphur or Dead Sea baths with no treatment or mineral baths with tap water baths or no treatment. Only one of the trials performed an intention-to-treat analysis and two studies provided data to perform an intention-to-treat analysis ourselves. A 'quality of life' outcome was reported by one trial. We found: silver level evidence concerning the beneficial effects on pain, quality of life and analgesic intake of mineral baths compared to no treatment (SMD between 1.82 and 0.34). a statistically significant difference in pain and function of Dead Sea + sulphur versus no treatment, only at end of treatment (WMD 5.7, 95%CI 3.3 to 8.1), but not at 3 month follow-up (WMD 2.6, 95%CI -1.1 to 6.3). no statistically significant differences in pain or function at one or three months of Dead Sea baths versus no treatment (WMD 0.5, 95%CI -0.6 to 1.6) or at one or three months of sulphur baths versus no treatment (WMD 0.4, 95%CI -0.9 to 1.7). Adverse events were not measured in the included trials.

AUTHORS' CONCLUSIONS

We found silver level evidence (www.cochranemsk.org) concerning the beneficial effects of mineral baths compared to no treatment. Of all other balneological treatments no clear effects were found. However, the scientific evidence is weak because of the poor methodological quality and the absence of an adequate statistical analysis and data presentation. Therefore, the noted "positive findings" should be viewed with caution.

The effect of combined therapy (spa and physical therapy) on pain in various chronic diseases

OBJECTIVE

Spa therapy is commonly used in the treatment of daily chronic diseases practice, but its benefits are still the subjects of discussion. This study investigates possible effects of a combined spa and physical therapy program on pain and hemodynamic responses in various chronic diseases.

METHODS

The pain intensity and hemodynamic responses of 472 patients involved in a spa and physical therapy program were studied retrospectively. Assessment criteria were pain [Visual Analog Scale (VAS)] and hemodynamic responses (heart rate, blood pressure, respiratory rate). Assessments took place before, immediately after treatment, and after completion of the spa program (before discharge).

RESULTS

The patients with ankle arthrosis, fibromyalgia and cervical disc herniation reported the highest VAS score before treatment program (P < 0.05). After the therapy program, VAS scores were seen to decrease compared to before treatment (P < 0.05). The patients with osteoarthritis of the hip (1.3+/-1.2) and soft tissue rheumatism (1.3+/-1.2) had the lowest VAS score before discharge compared to patients with other pathologies (P < 0.05). No statistically significant differences were detected between both sexes in terms of pain improvement (P > 0.05). On discharge, all hemodynamic responses decreased significantly compared to before and immediately after initiation of the therapy program (P < 0.01).

CONCLUSION

To decrease pain and high blood pressure without hemodynamic risk, a combined of spa and physical therapy program may help to decrease pain and improve hemodynamic response in patients with irreversible pathologies.

A pilot study of therapeutic massage for people with Parkinson's disease: the added value of user involvement

OBJECTIVE

To carry out a pilot study, with particular attention to adequacy of outcome measures.

DESIGN

Observational study and user participation.

SETTING AND PARTICIPANTS

A local user group selected seven participants with a wide range of illness severity.

INTERVENTION

A course of eight 1hr sessions of deep whole body (therapeutic) massage over 8 weeks.

OUTCOME MEASURES

The Parkinson's Disease Questionnaire (PDQ-39), the Measure Yourself Medical Outcome Profile (MYMOP), and the Medication Change Questionnaire (MCQ). Semi-structured interviews, before and after the intervention.

RESULTS

In addition to enjoying the massage, individuals showed improvement in self-confidence, well-being, walking and activities of daily living. There was good agreement between data from the outcome questionnaires, interviews and clinical notes. User involvement highlighted issues that would otherwise have been ignored.

CONCLUSIONS

The study confirms the benefits of involving users in the research process and makes recommendations concerning the design of any future randomised trial.

Comparison of a generic and a disease specific quality of life scale to assess a comprehensive spa therapy program for knee osteoarthritis

OBJECTIVES

To compare the differences or correlation between the results obtained from a generic and a disease-specific instrument for the study group and to assess the short-term effects of spa therapy on quality of life of patients with knee osteoarthritis.

PATIENTS AND METHODS

Fifty patients with knee osteoarthritis were randomly recruited. They underwent a comprehensive spa therapy program for 21 days. Forty-six patients completed the study. The results were evaluated with Medical Outcomes Study 36-Item Short Form-36 (SF-36) and Arthritis Impact Measurement Scale 2 (AIMS2).

RESULTS

Statistically significant improvement was observed in all subscales of SF-36. All subscales of AIMS2 improved too, but only half of them were significant. Correlation between matching subscales of each test was also significant, except physical activity.

CONCLUSION

Comprehensive spa therapy seems to increase the quality of life of patients with knee osteoarthritis for short term.

Balneotherapy for rheumatoid arthritis

BACKGROUND

Balneotherapy (spa therapy) for patients with arthritis is one of the oldest forms of therapy. One of the aims of balneotherapy is to soothe the pain, improve joint motion and as a consequence to relieve people' suffering and make them feel well.

OBJECTIVES

To perform a systematic review on the effectiveness of balneotherapy for rheumatoid arthritis.

SEARCH STRATEGY

Using the Cochrane search strategy, studies were found by screening: 1) The MEDLINE CD-ROM database from 1966 to June 2002 and 2) the database from the Cochrane 'Rehabilitation and Related Therapies' Field, the Pedro database up to June 2002. Also, 3) reference checking and 4) personal communications with authors was carried out to retrieve eligible studies. Date of the most recent literature search: June, 2002

SELECTION CRITERIA

Studies were eligible if they were randomised controlled trials (RCTs) comparing balneotherapy with any other intervention or with no intervention. Included participants all suffered from definite or classical rheumatoid arthritis (RA) as defined by the American Rheumatism Association Criteria (ARA) or by the criteria of Steinbrocker. At least one of the WHO/ILAR core set of endpoints for RA clinical trials had to be among the main outcome measures.

DATA COLLECTION AND ANALYSIS

The Delphi list was the criteria list used to assess the components of methodological quality. Two reviewers carried out quality assessment and data extraction of the studies. Disagreements were solved by consensus.

MAIN RESULTS

Six trials, representing 355 people, were included in this review. Most trials reported positive findings (the absolute improvement in measured outcomes ranged from 0 to 44%), but were methodologically flawed to some extent. A 'quality of life' outcome was reported by two trials. None of the trials performed an intention-to-treat analysis and only two performed a comparison of effects between groups. Pooling of the data was not performed; because of heterogeneity of the studies, multiple outcome measurements, and the overall data presentation was too scarce.

REVIEWER'S CONCLUSIONS

One cannot ignore the positive findings reported in most trials. However the scientific evidence is insufficient because of the poor methodological quality, the absence of an adequate statistical analysis, and the absence, for the patient, of most essential outcome measures (pain, self assessed function, quality of life). Therefore, the noted "positive findings" should be viewed with caution. Because of the methodological flaws an answer about the apparent effectiveness of balneotherapy cannot be provided at this moment. A large, methodological sound trial is needed.
