The Effect of Core Exercises on Pelvic Dysfunction, Sexual Dysfunction, Pain, Sleep Quality and Quality of Life in Women With Fibromyalgia

In fibromyalgia patients, exercise is needed to reduce symptoms and to prevent muscle weakness with fatigue and pain. Core exercise retrains and strengthens deep postural spinal muscles such as the multifidus and transverse abdominis by promoting neuromuscular control, maintaining the dynamic stability of the spine and thus reducing pain. By performing core exercises, the pelvic floor, which forms the lower base of the core, is strengthened.

Objective: It was planned to investigate the effects of core exercises on pelvic floor dysfunction, sexual dysfunction, pain, sleep quality and quality of life in women with fibromyalgia.

Materials and Methods: It was designed as randomized control. Sexually active women with fibromyalgia syndrome between the ages of 18-65 will be included in the study. After the patients are selected from the relevant stage with the improbable random sampling method, the patients who accept to participate in the study and meet the inclusion criteria will be assigned to one of the groups in which the core exercise or home program is applied. Evaluations will be evaluated for each group before starting the exercise program and 1 day after the last session, following the completion of 2 sessions per week for 8 weeks. Pain Visual Analog Scale; fibromyalgia impact level Revised Fibromyalgia Impact Questionnaire (FIQR); pelvic floor dysfunction Pelvic Floor Impact Questionnaire (PFIQ); sexual dysfunction Female Sexual Function Scale; sleep quality: Pittsburgh Sleep Quality Index; short quality of life It is planned to be evaluated with Form-36(SF-36). Conclusion: The effects of core exercises on pelvic floor dysfunction, sexual dysfunction, pain, sleep quality and quality of life will be evaluated and interpreted by comparing the evaluations before and after treatment and between groups.

Fibromyalgia (FM) is a non-articular, chronic rheumatic disease of unknown etiology, characterized by widespread musculoskeletal pain, sleep disturbance, mood changes, fatigue, and the presence of multiple tender points. Diagnostic criteria were defined by the American Rheumatism Association (ARA) in 1990. To diagnose FM, there should be widespread pain and tenderness at 11 or more of 18 specific points (1).

Although the etiopathogenesis of FM is still unknown, triggering factors such as physical trauma, surgical intervention, infections, acute or chronic emotional stress may play a role (2). Various findings such as muscular symptoms accompanying chronic pain, cognitive complaints, depression, insomnia and fatigue have been described in patients with FM (2). chronic pain seen in FM; It creates physical and emotional stress such as sleep, fatigue and cognitive symptoms. In addition, unwillingness to move or fear of movement may develop in individuals due to chronic pain (2).

Various psychopathological disorders have been reported in FM. It is estimated that 1/3 of his patients have minor depression or anxiety and anxiety state disorder. However, it is unknown whether anxiety and depression in FM cause chronic pain or contribute to the severity of symptoms (1). Despite various complaints of patients with fibromyalgia, the absence of a significant disorder in physical examination and laboratory tests suggests that the symptoms may be of psychological origin (2). Since the etiology of fibromyalgia syndrome is unknown, pharmacological and non-pharmacological treatment methods should be used in patient-specific combinations according to the prominent symptoms and their severity (2).

Sexuality is an important part of life and is associated with the well-being of the individual. Sexuality covers many issues, starting with the self-image of the person and the relationship with his partner (3). Sexual dysfunction is defined as the satisfaction of not participating in sexual acts (3). The development of sexual dysfunction in women with fibromyalgia is thought to be associated with many factors such as symptoms, pain, anxiety, depression, and drug therapy (3).

Few studies have been done on the sexuality of women with fibromyalgia (4), and studies have found a relationship between fibromyalgia and sexual dysfunction (4) In addition, considering that women with fibromyalgia have an increase in pain, fatigue, and decrease in muscle strength (5), Fusco et al. concluded that women with fibromyalgia exhibited weaker pelvic floor muscles and also more frequent lower urinary tract symptoms compared to the healthy control group (5). For this reason, a relationship between pelvic floor involvement and impaired sexual function in women with fibromyalgia is considered (5).

It is reported that sleep quality is deteriorated by almost 80% of patients with fibromyalgia (6). Epidemiological studies show that poor sleep quality is a risk factor for fibromyalgia. Poor sleep is associated with symptom severity in patients with fibromyalgia (6). It has been shown that improving sleep quality in exercise approaches as well as pharmacological treatments can reduce pain in patients with fibromyalgia (6,7).

When looking at the quality of life, studies comparing the quality of life in FM patients with healthy individuals of the same age show that FM has a negative effect, as symptoms affect daily routine and physical activities, causing patients to enter a vicious circle(8). Because fibromyalgia has a negative effect on fatigue, pain, anxiety, sleep disturbance symptoms, and poor quality of life, the American Pain Society and the Association of Scientific Medical Societies in Germany have recommended physical exercise, hydrotherapy, massage, yoga and various treatment strategies besides medication use. It is recommended in methods such as acupuncture (9).

The term core is used for the trunk or more specifically the lumbopelvic region of the body. Stabilization of the lumbopelvic region is very important for upper and lower extremity movements, supporting loads, protecting nerve roots and spinal cord. (10,11). core; It can be thought of as a box formed by the abdominals in the front, the paraspinals and gluteals in the back, the diaphragmatic roof above, and the pelvic floor muscles at the bottom. When the stabilization system works effectively, optimal control and efficiency of the movement, proper distribution of the force, adequate absorption of the ground effect force and protection of the joints in the kinetic chain are ensured. (12,13). The stabilization system consists of 3 sub-systems as neural, passive and active systems and are functionally interconnected (11). The neural system receives stimuli from the muscle spindle, Golgi tendon organ and spinal ligaments, adjusts the muscle strength, and determines the spinal stability requirements. Stability can change abruptly depending on the external loads that the body can carry along with postural adjustments. The neural system has to work synchronously with other systems in order to perform the desired movement and to provide sufficient stability (11). The passive system consists of spinal ligaments and facet joints and allows limited loading of the lumbar vertebrae. For this reason, an active system is needed to load and support body mass in resistant exercise-dynamic activities (11). The active system consists of muscles and tendons. The active musculature, on the other hand, has been divided into two as "global" and "local" according to their roles in core stabilization (11). The global group consists of large superficial muscles. The muscles in the global musculature are the erector spina, external oblique, and rectus abdominis (10). The local group is; It consists of deep and small muscle groups. The local musculature consists of transversus abdominus, multifidi, internal oblique, deep transversospinalis and pelvic floor muscles (10). For the continuity of spinal function, the simultaneous function of the global and local groups is required (13). Core muscles consist of 2 types of muscle fiber structures that contract slowly and quickly. Slow-twitch fibers are mainly located in the local system known as the deep layer, providing intersegmental movement control and posture changes. Fast-twitch fibers are found in the superficial layer, that is, in the global musculature. These muscles are fibers with large torque capability focused on speed, power, and greater range of motion (10-13). Pelvic floor muscles form the base of the core muscles. The pelvic floor not only plays an important role in muscle activation for lumbar stabilization, but also forms the basis of the abdominal cavity. Pelvic floor muscles; During work that increases intra-abdominal pressure, it should contract in order to maintain continence and contribute to the increase in pressure (14). It has been reported that the contraction of the pelvic floor muscles can be strengthened by the activation of the trunk stabilizing muscles. Therefore, trunk stabilization exercises are thought to be an option to increase the effectiveness of pelvic floor muscle exercises (15).

Pelvic floor dysfunction is defined as the abnormal function of the pelvic floor and includes conditions that may have significant adverse effects on a woman's quality of life, such as urinary incontinence (stress, urge, and mixed), fecal incontinence, pelvic organ prolapse, and sexual dysfunction (16).

Core exercise is recommended in the rehabilitation of chronic pain (17). Few studies on the management of pain in fibromyalgia have focused on core exercise (18). The main purpose of core exercise is to promote neuromuscular control and retrain and strengthen the deep postural spinal muscles such as the multifidus and transversus abdominis, maintain the dynamic stability of the spine and thus reduce pain (19,20). Core exercise alone reduced pain and depression and improved health status, quality of life and sleep quality in women with FM(19-22).

Core exercise focuses on activating the deep local musculature, regulating overactivity of surface muscles, and restoring normal synergistic function between local and global musculature, thereby reducing pain and improving function (19,21). Although the positive effects of core exercise on chronic pain such as low back pain are well known (21), the number of studies focusing on core exercise in axial pain, which is common in FM, is insufficient. Only one study in the literature focused on investigating the effects of specific core exercise on FM (18). Martinez-Rodriguez et al. (18) recently found that core exercise plus lacto-vegetarian diet contributed to the reduction of pain and improvement of body composition in FM. The current study reveals that core exercise alone is effective in reducing pain and depression and improving health status, quality of life and sleep quality in FM.

When we look at the literature, many studies have revealed that the symptoms of fibromyalgia syndrome such as fatigue, depression, pain and sleep disturbance are also associated with sexual dysfunction by affecting the pelvic floor (8). In line with this information, our aim is to examine the effects of core exercises on pelvic floor dysfunction, sexual dysfunction, pain, sleep quality and quality of life in women with fibromyalgia.

Pain Visual Analog Scale; fibromyalgia impact level Revised Fibromyalgia Impact Questionnaire (FIQR); pelvic floor dysfunction Pelvic Floor Impact Questionnaire (PFIQ Pelvic Floor Impact Questionnaire); sexual dysfunction Female Sexual Function Scale; sleep quality: Pittsburgh Sleep Quality Index; It is planned to evaluate the quality of life with Short Form-36 (SF-36).

5.5. Data collection tools: Data Collection Inonu University Turgut Özal Medical Center Rheumatology Department diagnosed with fibromyalgia by the relevant specialist, sexually active women between the ages of 18-65 will be included in the study. Individuals will be evaluated for compliance with the study content before the preliminary evaluation. After eligibility is determined, individuals will be randomly assigned to groups. In the randomization of the groups, the assignment will be made to the groups with the randomizer program using the computer. Evaluations will be evaluated for each group at the same time of the day before the exercise program starts and 1 day after the last session after completing 2 sessions a week for 8 weeks.

Evaluation form : Sociodemographic data of individuals will be questioned with an evaluation form. Evaluation form; patient's name-surname, age, gender, height, weight, marital status and duration of marriage, age at diagnosis and education level.

Pain: Regional neck and back pain at rest and during activity will be evaluated with the help of the Visual Analogue Scale (VAS). The VAS is a 10 cm scale that rates 0 points as "no pain" and 10 points as "worst pain imaginable".

Fibromyalgia Impact Level : Revised Fibromyalgia Impact Questionnaire (FIQR) will be used. This scale; physically It measures 10 different features: function, well-being, not being able to go to work, difficulty at work, pain, fatigue, morning fatigue, stiffness, anxiety and depression. With the exception of the well-being trait, low scores indicate recovery or less affliction. FEA is filled by the patient. The maximum possible score of each sub-title is 10. Thus the total maximum score is 100. The average FM patient scores 50, while more severely affected FM patients usually score above 70. Permission to use the survey has been obtained.

Pelvic floor assessment: Pelvic Floor Impact Questionnaire (PFIQ Pelvic Floor Impact Questionnaire) will be used for measurement. The PFIQ is a pelvic floor quality of life questionnaire used to evaluate the effects of bowel, bladder, and/or pelvic symptoms on an individual's activities of daily living, social relationships, and emotions. Each item consists of 4 options (Never, Rarely, Moderately, Quite often) and is scored between 0 and 3. The PFIQ scale also consists of 3 sub-dimensions. POPIQ-7 (Pelvic organ prolapse impact questionnaire): In this sub-dimension consisting of 7 questions, it is questioned how the pelvic organ prolapse affects the patient during travel, social activity and physical activity and the effect of this situation on emotional health. CRAIQ-7 (Colo-rectal-anal impact questionnaire): In this sub-dimension consisting of 7 questions, it is questioned how intestinal complaints affect the patient during travel, social activity and physical activity and the effect of this situation on emotional health. The mean scores of the items in each sub-dimension are calculated and these scores are multiplied by (100/3) and PFIQ subscale scores ranging from 0-100 are calculated. Then, the 3 subscale scores are summed to find the PFIQ total score, which ranges from 0-300. A higher score indicates worse health. Permission to use the survey has been obtained.

Sexual Dysfunction: It will be measured with the Female Sexual Dysfunction Scale. The scale consists of 19 questions. Each The question has six options to answer, and each item is scored from zero to five. In the structure of the scale; There are six sub-dimensions: desire, arousal, lubrication, orgasm, satisfaction and pain. The person gets a score between 4 and 95 from the scale. Permission to use the survey has been obtained.

Sleep Quality: Pittsburgh It will be measured by the Sleep Quality Index. Defining good and bad sleep and assesses sleep quality. It consists of a total of 24 questions, 19 of which are self-evaluation and 5 of which are answered by the spouse or roommate of the person. The questions are collected in 7 subscales. These are: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping pills, and daytime dysfunction. Each subscale is scored between 0-3 points. The total score is between 0-21. Questions asked to an individual's spouse or roommate are not included in the calculation. Permission to use the survey has been obtained.

Quality of life: The Short Form-36 (SF-36) scale will be used. Assessing the SF-36 quality of life developed for the purpose. A validity and reliability study was conducted in Turkey. SF-36 is used to compare general and specific populations, to demonstrate the health benefits of different treatments, and to monitor patients. The last 4 weeks are taken into account in the evaluation of SF-36, which consists of a total of 36 items. It is stated that due to the release of SF-36 v2.0, the use of v1.0 does not require permission.
