Descrizione dettagliata

The prevalence of the musculoskeletal manifestations is high (76.4%) in the hemodialysis population .Pain is the most frequently reported symptom (44.9%). Seven studies (28%) reported back pain With a prevalence ranging from 14.29%-52%. In hemodialysis patients, Low back pain (LBP) can be attributed to sedentary lifestyle ،low physical performance, muscular weakness ،psychological factors, altered metabolic activity of the bones and joints, and rare causes such as tumor, spinal infection, and osteoporotic fractures.

Diaphragm is an important component of spine lumbar stability. In presence of low back pain ،there may be some alterations in this muscle like other muscles that are responsible for lumbar stabilization. Respiratory muscle training (RMT) has been proven to reduce pain intensity and improve respiratory muscle strength, physical function, balance, and consequently، the overall quality of life in several population groups.

Pneumatic compression device had a significant improvement in pulmonary functions and inspiratory muscle training. And pneumatic compression can be considered as an effective component for pulmonary rehabilitation in chronic obstructive pulmonary lung disease. patients. Up to investigated knowledge, No previous studies conducted to explore the effect of pneumatic compression versus Inspiratory muscle training on diaphragmatic function in patients with low back dysfunction .

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Pneumatic compression and inspiratory muscle Trainer group
Participants will receive resisted inspiratory exercises using pneumatic compression abdominal belt in addition to inspiratory muscle Trainer (3 sessions per week) for 12 weeks
Dispositivo: Pneumatic compression device
Training program in the form of resisted inspiratory exercises using pneumatic compression device with abdominal sleeve on the top portion of the abdominal cavity beneath the xiphoid process. The patient used a pursed-lip breathing method to exhale after inhaling slowly through the nose such that the stomach slid out against the abdominal sleeve of the device. For 12 weeks, three times per week, the workout consisted of 10 sets with 4-5 breaths in each set and a rest period of 2-3 minutes.
Dispositivo: Inspiratory muscle Trainer
the subject underwent training in the form of six sets of five deep breaths against the trainer, with 1-2 minutes of rest in between sessions. Depending on their rate of perceived exertion, the patient determined the maximum training load at which they could effectively perform 10 breaths at maximum resistance. A load equivalent to 30% of the patient's maximum inspiratory effort was used to begin the training .This unique load gradually increased as the inspiratory muscle got stronger. At the conclusion of the three months, the training programmer had expanded by 5% to 10% per week, reaching 60% of the maximum inspiratory pressure.
Comparatore attivo: Inspiratory muscle Trainer group
Participants will receive only training of the inspiratory muscles by (Threshold Inspiratory Muscle Trainer) (3 sessions per week) for 12 weeks

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Diaphragmatic excursion
Lasso di tempo: 12 weeks
Ultrasonography is an ideal tool and easy to be operated for evaluating diaphragm function. Low thickening ratio at forced respiration is an early indicator of diaphragm dysfunction and is associated with adverse clinical outcomes in hemodialysis (HD) patients. These findings suggest that routine screening for diaphragm dysfunction is in HD patients and intervention of diaphragm dysfunction is expected to be a novel strategy for improving the clinical outcomes in HD patients.
12 weeks
Pain intensity
Lasso di tempo: 12 weeks
Visual analogue scale (VAS) will be used to assess pain intensity. it is 10 centimeter line with 2 ends; 0 indicates no pain and 10 indicates the worst pain.
12 weeks
functional capacity
Lasso di tempo: 12 weeks
The 6 Minute Walk Test (6MWT) is a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity. The patient will rest comfortably for 10 minutes prior to the test. During this time blood pressure and heart rate are measured and potential contraindications assessed. The 6MWT will be performed on the walking track in which is 30 meters on one lap and two small cones will be used to mark the walking track boundaries.

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Functional disability
Lasso di tempo: 12 weeks
The Oswestry Disability Index (ODI) has become well-researched gold standard for assessing the severity of disability caused by back pain. The ODI covers 1 item on pain and 9 items on activities of daily living (personal care, lifting, walking، sitting, standing, sleeping, sex life, social life, and traveling. Each section contains 6 statements scored from 0 to 5, where 0 is no disability and 5 is the maximum. Scores are calculated as a percentage: (Total Points ÷ Total Possible Points) × 100.
12 weeks
Health-related Quality of life
Lasso di tempo: 12 weeks
The SF-12 Health Survey Questionnaire is used to evaluate the health-related quality of life (HR-QoL) before and after the interventions. The SF-12 consists of 12 questions that examine eight different health domains in order to determine physical and mental health. General Health (GH), Physical Functioning (PF), Role Physical RP), and Body Pain (BP) are the physical health domains. Vitality) VT), Social Functioning (SF), Role Emotional (RE), and Mental Health (MH) are mental health-related scales. A score above 50 indicates better-than-average health, while a score below 50 indicates below-average perceived health.
