To Investigate Influence of a Combined Interferential Current Stimulation and Abdominal Draw -in Exercises in Patients with Chronic N
Conditions
Brief summary
The purpose of this study is to investigate influence of a combined interferential (IF) current stimulation and abdominal draw-in exercises on the abdominal muscle thickness, TrA endurance, pain intensity and function disability in patients with chronic non-specific LBP (CNSLBP) CNSLBP is considered the second most common health problem after headache. The lifetime of LBP among Egyptian patients in a family center reached 48%, which indicates that LBP is a prevalent symptom that deserves more attention. One hypothesis for the development of LBP is due to a dysfunction in the control of the abdominal and back muscles and this change in spinal control is due in part to in local segmental muscles dysfunction, such as the transversus abdominis (TrA). Interferential therapy (IFT) is capable of achieving uniform stimulation and high reproducibility, it is thought to be less stressful, as well as enhance deep muscle contraction. Also, there is the specific training of the TrA provided functional and therapeutic benefits, such as unloading of the spine, anticipatory postural control, intersegmental stabilization of the spine, and long-term pain relief. Draw-in is a typical TrA exercise. Many studies have mainly focused on the morphological aspects of paraspinal muscles which play an essential role in patients with CNSLBP while our study focused on influence of a combined IFT stimulation and abdominal draw-in exercises on the abdominal muscle thickness, TrA endurance, pain intensity and function disability in patients with chronic non-specific LBP (CNSLBP
Detailed description
60 patients suffering from chronic non-specific low back pain will participate in this study. Both sexes will participate in this study; aged 20-45 years. will be diagnosed and referred from Orthopedist. The study will be conducted at outpatient clinic of Deraya university Elmina government. The patients will be divided randomly into two groups equal in numbers (group A), (group B). Group(A): (Experimental group) :( 30 patients will receive IFC stimulation, Draw In exercises from prone position, hot pack, back muscles stretching and strengthening exercises for the back and abdominal muscles). Group(B): (control group) (30 patients will receive Draw In exercises from prone position, hot pack, back muscles stretching and strengthening exercises for the back and abdominal muscles).
Interventions
IF Current parameters will be applied as follow: Amplitude modulated frequency (AMF) 30Hz, Autosweep-5 sec, Dose-15 minutes, type of current dynamic vector field (Mitra, 2006), three days per week over four weeks (Corrêa et al., 2016) and current intensity will be increased gradually, according to the subject's condition
OTHERDraw- In exercises,,
From prone position, participants will lay face down on the bed and flexed their hips and knees at 0°. A PBU will be positioned below the pubis symphysis with the decreasing edge consistent with the ASIS and will be overstated to 70 mmHg. The participants will be trained to gently draw in the lower part of the abdomen under the navel. In addition, while maintaining the neutral pelvic position, the movement of the upper part of the abdomen will be restricted so that the pressure will be decreased by approximately 10 mmHg. The participants will maintain this position for 10 s
