Abstract

Aim: The current study focused on examining the effect of local cold compression upon pain and movement restriction among patients with knee osteoarthritis.

Background: Knee Osteoarthritis (OA) is one of the most common noninflammatory rheumatic joint diseases which occurs on synovial bone as a result of imbalance between joint cartilage synthesis and its destruction. And it characterized with damaged joint cartilage, new bone formation on joint cartilage, joint pain and movement restriction. The aim of knee OA treatment is to control pain, movement restriction and other symptoms, to slow disease progression, to increase and to maintain patients’ movement function. Local cold compression, one of the non-pharmacologic methods, produces such effects as eliminating/reducing pain, preventing edema and slowing inflammation process by providing local therapeutic anesthesia. Therefore, importance of cold compression is emphasized among patients with arthritis.

Design: This was a semi-experimental study designed with one group in pre-test and post-test model.

Method: The study population was composed of ambulatory patients who presented to Orthopedics and Traumatology, Physical Treatment and Rehabilitation Policlinics of Erzurum Palandoken Public Hospital. The study sample was consisted of 70 knee OA patients who were diagnosed with knee OA by physicians, whose diagnosis was clinically confirmed in collaboration with physicians according to criteria of American College of Rheumatology, volunteered to participate in research study, had no cold allergy or sensitivity, were able to communicate and did not have any psychological disorder. The study was done by observing these 70 patients who were assigned to experimental group (n=35) and control group (n=35). The data were collected after oral consent and written informed consent was obtained from the patients. The data were collected using Socio-Demographic Information Form, Health Assessment Survey, Numerical-Rating Scale and Cold Compression Chart. For the analyses of the data, t-test and two-factor ANOVA with repeated measures were used and analyses were processed with SPSS for Windows 15.00 Release statistical package software.

Results: In the study in which knee OA patients received cold compression, it was identified that difference between the patients with OA knee in the experimental and control groups was statistically significant in terms of average post-test scores regarding pain complaint (t=-2.397, p=.020). It was found that as compared to the control group, local cold compression applied to the experimental group provided bigger decrease in pain complaints in the posttest than pre-test. In the study in which knee OA patients were treated with cold compression, it was identified that difference between the experimental and control groups was statistically insignificant in terms of average post-test scores regarding movement restriction complaint (t=-.924, p=.359). According to the repeated measures, it was noted that being in a different group did not produce any statistically significant difference in movement restriction complaints (F(1,59)=8.149 p=.006); which made us suggest that the experimental group patients and the control group patients showed different results in terms of decrease in movement restriction complaints.

Conclusion: We are of the opinion that cold compression will be beneficial for preventing pain and movement restriction among patients with knee OA.

Relevance to Clinical Practice: It may be recommended that OA patients should be informed about cold compression and its benefits and patients should be encouraged to apply cold compression by themselves at home.

Introduction

Treatment and care of musculoskeletal system diseases, which increases with aging, play a crucial role in maintaining health and improving quality of life. One of these diseases is osteoarthritis prevalence of which is very high-particularly- among those over 50 years [1]. OA is the most common form of arthritis and is defined as degenerative joint disease caused by inflammation, stiffness, and eventually by cartilage loss [2]. Knee OA is a widely prevalent joint disease over the world. In the USA, OA affects nearly 40 million women and men. It is estimated that this ratio, which almost makes up 15% of the general population, will rise to 18.2% by 2020; in other words, 59.4 million Americans will be affected [3]. It is also estimated that by 2030 there will be 67 million people diagnosed with OA in the United States [4]. “Turkey Osteoarthritis Study (2005)”, is considered as the most extensive study in Turkey on this issue, it is stated that one man versus three women is OA patient. However, the study done with 3755 OA patients in nine provinces does not shed light on the ratio of the population affected by OA [5]. The knee osteoarthritis rate in Turkey is reported to be 14.8% [6]. The most crucial clinical signs of knee OA are pain, movement restriction and joint stiffness. The aim of knee OA treatment is to control pain, movement restriction and other symptoms; to slow disease progression; to increase and to maintain patients’ movement function [7,5,8]. It is widely accepted that no methods can prevent the disease completely [9,10]. Therefore, patients should protect themselves from side effects of the treatments. In many cases, pharmacological and non-pharmacological methods can be employed together as these are the best ones in pain control [11,9,10]. Local hot or cold compression, which is a nonpharmacological method, has been used for a long time for reducing pain, stiffness and swelling among OA patients [12,13]. Generally; physiological effects of hot are vasodilatation, increase in capillary permeability, acceleration of cell metabolism, muscle relaxation, acceleration of inflammation, reducing pain by relaxing muscles, sedative effects and reducing joint stiffness by decreasing synovial fluid [14]. In a study done by Mazzuca et al. [15], heat-retaining knee sleeve was compared to cotton elastic knee sleeve and the difference between was found statistically insignificant. In this study, patients continued pharmacological treatment. Physiological effects of cold are vasoconstriction, slowing down in cell metabolism, local anesthesia, reduce in blood flow, oxygen, metabolite flux to the site and waste products. Therefore, local cold compression exerts such effects as reducing/terminating pain, preventing edema and slowing down inflammation process by providing local anesthesia therapeutically. Therefore, importance of cold compression among arthritis patients has been emphasized [16,14,17].

Research Hypotheses

H.1. Cold compression applied to patients with knee osteoarthritis reduces pain.

H.2. Cold compression applied to patients with knee osteoarthritis reduces movement restriction.

Background

Osteoarthritis is a chronic disease that is characterized with joint cartilage erosion, bone hypertrophy to bone edges, biochemical and morphological changes in sub-chondral sclerosis, synovial membrane and joint capsule and leads to movement restriction, disability and severe pain. Knee OA is characterized with deterioration in joint cartilage covering over the edges of joint bones [4,18,19]. Knee OA affects 20.7 million Americans aged 45 and over. It is estimated that 46 million annual doctor visits occur and 3.7 million patients are hospitalized in the USA due to knee OA. In our country, although the studies relating to prevalence of musculoskeletal system diseases are insufficient, in a study undertaken by Seçkin et al. [20], it was identified that 33% of 1560 geriatric patients who were aged 65 and over and who visited a physical treatment and rehabilitation policlinics in 1998 were diagnosed with knee OA.

Etiology of OA is not known exactly. It is stated that mechanic, bio-mechanic and genetic factors play a role [10,21]. The most important factors that are effective in the formation of knee OA are obesity, sex, age, traumas in knee joints, working in jobs that require excessive mechanic force against knees such as climbing up stairs, knee bending, sportive competitions that force or damage joints, wearing high heel shoes, lack of movement and genetic predisposition [12,22]. The most evident symptoms of knee OA are pain, movement restriction and strong stiffness in joints in the mornings. Knee OA diagnosis is made through patient history, radiography and physical examination. There are not any standard diagnosis tests for knee OA. However, laboratory tests are principally used to make a definitive diagnosis and to rule out other rheumatic diseases [23]. For knee OA diagnosis, certain criteria have been designated by the American College of Rheumatology (ACR) [2]. There is no treatment that will stop degenerative process in knee OA, but with a suitable treatment, patients are relieved effectively. As pointed out by Kartal, the aim in knee OA treatment is to control pain, movement restriction and other symptoms, to provide optimal joint function, to reduce movement restriction and to raise awareness among patients and their families about the disease and its treatment [24,19]. Cold compression is locally or systemically applied for therapeutic purposes and provides a drop in tissue temperature. Cold treatment has empirically been used since ancient ages for curing some diseases. The study of Metin [16] reported that first ice compression for joint problems was done by Swdomae in 1823 to cure gouty joints and Swdomae wrote a book on therapeutic use of ice in 1824 [5,8]. In the treatment of knee OA, the aim is to improve the quality of life by controlling pain, stiffness and other symptoms, slowing the progression of the disease, increasing and maintaining the physical function of the patient. In this respect, it is thought that this application may help treatment because of the low side effects, easy application and non-invasive application [14]. Although the aim in knee OA treatment is to eliminate symptoms of the disease, the first step is to train patients [5,8]. Nurse, playing a significant role in rehabilitation team, is the one who informs patients and their families about disease progress and the outcomes through highlighting his/her training role and spending more time with patients. A training that will teach patients about self-practiced methods like coping methods will enhance patients’ adaptation into treatment and prevent possible complications in the future. Moreover, nurse can very well observe and assess outcomes of the treatment arranged by the physician [25,26]. Owing to his/her responsibility to provide a care of higher quality, nurse must base nursing decisions on evidences. It is crucial that nursing compressions should be evidentbased in order to improve quality of care and care results, to create a difference in clinical compressions and patient care, to standardize care and to increase nurse satisfaction [27,28].

Methods

This was a semi-experimental study designed to assess the effect of local cold compression upon pain and movement restriction among knee OA patients. The study population was composed of ambulatory patients who presented to Orthopedics and Traumatology, Physical Treatment and Rehabilitation Policlinics of Erzurum Palandoken Public Hospital and were diagnosed with knee OA. The study sample was consisted of 70 knee OA patients who were diagnosed with knee OA by physicians, whose diagnosis was clinically confirmed in collaboration with physicians according to criteria of American College of Rheumatology. These patients, who had no cold allergy or sensitivity, volunteered to participate in study. They were able to communicate and did not have any psychological disorder. The study was done by observing these 70 patients who were assigned to the experimental group (n=35) and control group (n=35).Those patients who joined the study and were diagnosed with knee OA in line with ACR criteria were randomly recruited to -first- the experimental group and –then- to the control group according to medical examination queue. 4 patients in the experimental group and 5 patients in the control group did not want to participate in and dropped out the study because some did not want cold compression and some were not contacted. Thus, the study was done with 61 patients.

Following tools were used in the study in order to collect data:

Ethical considerations

Ataturk University Health Sciences Ethical Board ethically found the study suitable (Ethics Approval Number: 018448-018449). The necessary written official permission from the hospital management of Palandoken State Hospital was obtained for implementation phase of the research (Approval Number: 25475-321). Before initiating compression, all patients were informed regarding the purpose of the study and study plan and their oral consents/written were also obtained.

Procedure

The data of the study were collected by the researcher using Numerical-Rating Scale, Health Assessment Survey, Sociodemographic Information Form the 70 knee OA patients were randomly recruited as the experimental and the control groups according to policlinic visits. During the compression step of the study, patients were informed by the researcher about the compression and oral consents of those patients who joined the study were obtained. Data collection form (Socio-demographic Information Form), Health Assessment Survey (HAS) and Numerical-Rating Scale-NSR were filled in by the researcher through face to face interview method. Statements in these forms were read to patients and response of the participants was recorded. In addition to routine treatment plan recommended by the physician, the patients in the experimental group received cold compression for 15 times in total for 4 weeks and every other day. The first compression was performed to the patient by the researcher at the first interview and the patient had a training related to how compression should be applied. As for the control group, they did not receive any other compression or treatment except the one recommended by the physician. As the pharmacological treatment, paracetamol-type medications and topical creams were given to the ambulatory patients who were examined at the policlinics and were diagnosed with knee OA by the physicians. The patients who made up the experimental group were contacted on phone every other day and were told to apply cold compression on OA knees and were asked to fill in the cold compression charts. These charts were also filled in by the researcher, too. As a result of four week compression, the patients in the experimental group were recalled back to hospital together with the cold compression charts they filled in. For the patients in the control group, an appointment was made to interview again four weeks later.

Data analysis

For the analysies of the data, two different statistical analyses were employed and these analysies were processed via SPSS for Windows 15.00 Release package program. These analysies were t-test and twofactor ANOVA with repeated measures, a multi-factor model often used for the data clustered by two factor mixed models.

Findings

Table 1 included participants’ demographic characteristics. When the demographic characteristics were investigated, it was found that 82% of the participant patients were female, 18% of them were male, 19.7% of them were aged between 30 and 49 years, 41% of them between 50 and 64 years and 39.3% of them =65 years, 41% of them were illiterate in terms of educational status. 95.1% of them were not employed/working, all of the participants were married and 59% of them had a systemic disease. As for the Body Mass Index, 50.8% of the patients were obese, 39.3% of them were of overweight and 9.8% of them were of normal weight. It was identified that 60.7% of the participant patients were referred to hospital because of knee pain while 39.3% of them due to both knee pain and movement restriction. 70.5% of the patients previously went to hospitals due to pain and movement restriction complaints. The ratio of the patients whose one knee was affected by OA was 68.9%. According to duration of disease, it was seen that 52.5% of the patients suffered from knee OA for 1-4 years. 63.9% of the patients reported no history of damage or injury to knee joint(s). It was identified that 52.5% of the patients did not have any OA patients in the families while family members of 47.5% of the patients had OA -such as fathers, mothers and siblings.
