The following document is a critique of 'Physical Training in Rheumatoid Arthritis: A Controlled Long-Term Study. I' by Rolf Nordemar, Björn Ekblöm, Lars Zachrisson & Kristina Lundqvist (1981) found in the Scandinavian Journal of Rheumatology.
What is the background to this research?
editRheumatoid Arthritis (RA) is an autoimmune disease that affects the joints within the body. [1] [2] [3] [4] An autoimmune disease involves the body's immune system attacking itself as opposed to its task of protecting against foreign substances. [2] [3] [4] Joints are affected by the thickening of the synovial fluid in the joint which can cause swelling, pain, stiffness and damage in the affected joints. [2] This can adversely impact on the mobility of the person with RA which is why physical activity is a major discussion point for these respective patients. Rheumatoid arthritis is more prevalent in women and affects around 458,000 Australians. [5]
As evident with many diseases, obesity and inactivity are risk factors for Rheumatoid Arthritis clarifying the need for appropriate exercise programs. [4] Contradictory though, RA causes patients to reduce physical activity due to the joint pain suffered and a fear of worsening their condition. [1] Studies and information available on Arthritis websites do however stress the fact that physical activity is safe for people with Rheumatoid Arthritis to participate in. [1] It does however need to be altered to suit the severity of their specific case of the disease. [1] [2] [3] [4] [6] [7]
Where is the research from?
editThis research was conducted in Sweden from the Department of Physical Medicine and Rehabilitation, Karolinska Hospital, the Department of Physiology III, Karolinska Institute and the Departments of Diagnostic Radiology and Rheumatology and St. Erik's Hospital, Stockholm. [1] St. Erik's Hospital was the clinic where the patients for the study were selected from. This research is published in the Scandinavian Journal of Rheumatology which is an International journal useful for different health practitioners and focuses on clinical and experiment rheumatology. [8]
The authors for this research have ten years of experience in the field, specifically with RA which makes them knowledgeable in this area. [1] The lead author Rolf Nordemar has been at the helm of many other RA studies surrounding different areas of physical activity and the disease. [9]
What kind of research was this?
editThe study conducted was a controlled long-term study which can also be called a Randomised Controlled Trial. [1] Studies that use a control involve having a group that changes what it does with a variable i.e. the exercising cohort, while the other group, the control, continues to live a lifestyle where they are not partaking in this change of variable.
Randomised Controlled Trials can be both highly positive and negative in the results that they produce. If done carefully with the control it can help to influence prescription of exercise. If done incorrectly however, prescriptions could be given with the possibility of causing potential harm to a patient. [10]
Participant criteria included:
- Adhere to ARA criteria,
- Moderate disease activity and
- Functional stage I, II or III. [1]
What did the research involve?
editThis research was a 4 to 8 year study where 23 patients from St. Erik's Hospital were part of a physical training study where there were an equal amount of participants also in the control group from 1970-1978. [1] There were 19 females and 4 males in both groups within the study since females have a higher prevalence of Rheumatoid Arthritis. [5] These patients ranged in age from 31-70 years. [1]
The training program consisted of both home-training (which requires high levels of intrinsic motivation) and group-training which was led by a physiotherapist (to ensure that physical activity is completed as safe as possible).
Strengths of the Study
- Had a control group as part of the study.
- Completed the study over a number of years.
- Used specific criteria to select participants to ensure certain level of chronic disease.
Limitations of the Study
- Lost some participants along the way.
- Some participants in the active group stopped partaking in physical activity and some people from the control group started to exercise on their own accord but were still classified as their original group classification.
- Is an outdated study now, so new technology and studies would be able to reassess outcomes of this study.
What were the basic results?
editKey results evident from the study include:
- Lower values in Lansbury's joint index in the training group (TG). [1]
- The increase in sick-leave was higher over the 8 year period in the control group (CG) - 29% increase as opposed to 1% in the TG. [1]
- CG spent more time in hospital than the TG - more than two times the amount. [1]
- There was less progression of joint damage in the TG as opposed the to CG. [1]
- Improvements in muscle was also seen in the TG along with improved ability to walk up stairs and complete the step test. [1]
- Positive psychological changes occurred with most participants agreeing that physical activity was beneficial for them in relation to rheumatoid arthritis and that they were likely to participate in this type of exercise into the future. [1]
What conclusions can we take from this research?
editOverall the outcome of this research was that physical activity is beneficial for patients with Rheumatoid Arthritis. [1] The study found that physical activity can help to reduce the progression of the disease which is beneficial for function in daily life. [1] Further to this, it was evident that physical activity done at an increased rate was more beneficial than less regular exercise. [1]
These conclusions have been backed up by other, newer studies and website information in the positive correlation between physical activity and Rheumatoid Arthritis. [2] [3] [4] [6] [11]
Practical advice
editRheumatoid arthritis is currently incurable, but can be treated so should be prevented where possible and treated as early as possible.
Preventative measures:
- Avoiding smoking.
- Monitoring environmental exposure to substances such as asbestos and silica.
- Maintenance of healthy weight range i.e. avoiding obesity.
Unfortunately risk factors such as aging, being female and having a family history are unmodifiable determinants therefore not being avoided.
Treatment measures:
- Seek doctor advice.
- Participate in regular physical activity.
- Exercise at a moderate intensity where possible.
