Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary supplies, and particularly relates to a special portable detection ruler for the separation distance of rectus abdominis muscles. Background Technique
[0002] The rectus abdominis muscle (RA) is a banded multi-abdominal muscle located on both sides of the midline of the anterior abdominal wall, and has important functions such as providing core stability and support, flexing the trunk, maintaining abdominal pressure, assisting breathing, maintaining the pelvic inclination, and childbirth. Diastasis recti abdominis (DRA) refers to the abnormal widening of the bilateral inter-recti distance (IRD) at the linea alba and the increase in the width of the linea alba (LA). At present, in China, a bilateral rectus abdominis muscle separation distance > 2.0 cm is used as the diagnostic criterion. Postpartum diastasis recti abdominis means that during pregnancy, a woman's muscles and ligaments and other tissue structures have decreased elasticity under the influence of relevant hormone levels in the body; as the gestational week increases, the continuously growing fetus causes the abdominal wall muscles to be passively stretched and extended, especially having a greater impact on the linea alba and the bilateral rectus abdominis muscles, resulting in a decrease in the elasticity and tension of the linea alba, the rectus abdominis muscles separating to both sides, and the contraction strength of the abdominal muscles gradually weakening, thus leading to diastasis recti abdominis.
[0003] As one of the common complications during pregnancy and after childbirth, diastasis recti abdominis can occur around 14 weeks of pregnancy and gradually worsen until childbirth as the gestational week increases. Epidemiological investigations by Kamel et al. showed that the incidence of diastasis recti abdominis in the late pregnancy was 66%-100%, the incidence at 6 weeks after childbirth was 50-60%, and it was still up to 39-45% after 6 months. In 2020, a cross-sectional study in France also found that the incidences of diastasis recti abdominis at 6 weeks, 6 months, and 12 months after childbirth were 60.0%, 45.5%, and 32.6% respectively. A Meta-analysis of the incidence of diastasis recti abdominis in postpartum women of childbearing age also showed that the average incidence of diastasis recti abdominis in postpartum women of childbearing age in China was as high as 45.14%. Thus, it can be seen that the incidence of diastasis recti abdominis in pregnant and postpartum women in the late pregnancy and after childbirth is still at a relatively high level. Some parturients with diastasis recti abdominis can naturally recover within 1 year, but still 35-70% of the parturients cannot recover without rehabilitation care or exercise. The rehabilitation care of postpartum diastasis recti abdominis cannot be ignored.
[0004] With the substantial increase in the number of elderly multiparous women, the incidence of diastasis recti abdominis after childbirth has increased accordingly. If parturients with diastasis recti abdominis after childbirth cannot receive corresponding rehabilitation care in a timely manner, or are affected by wrong traditional concepts, it is extremely easy to lead to a series of adverse symptoms, such as unsteady gait caused by weakened core stability, anterior pelvic tilt caused by weakened pelvic stability, postpartum low back pain caused by compensatory strain of lumbar muscle groups, and body restriction during physical activities. In severe cases, it can also lead to prolapse of abdominal organs and abdominal hernia, etc. These adverse symptoms will seriously endanger the physical and mental health of parturients and reduce the quality of life after childbirth. In addition, changes in abdominal appearance such as abdominal bulging, abdominal obesity, and abdominal wall wrinkles can also occur in diastasis recti abdominis after childbirth, affecting the physical beauty of postpartum women and leading to adverse psychological emotions such as self-aesthetic discomfort, anxiety, and even depression in parturients. Therefore, enhancing the awareness of diastasis recti abdominis rehabilitation in parturients and conducting screening and rehabilitation treatment in a timely manner are of great significance.
[0005] The measurement of the rectus abdominis muscle distance, as an important indicator for the evaluation of diastasis recti abdominis and the intervention effect, the accuracy of the measurement results can affect the judgment of the treatment effect by medical workers and the adjustment of the overall rehabilitation plan to a certain extent. At present, the measurement of the rectus abdominis muscle distance mainly includes finger measurement method, ruler measurement method (standard caliper or vernier caliper), ultrasonic detection method, and CT detection.
[0006] Considering that the ultrasonic and CT measurements are expensive, the finger measurement method and the ruler measurement method are mainly used in current clinical work for the preliminary measurement of the rectus abdominis muscle distance. ① The finger measurement method is simple and easy to operate without professional equipment, but the measurement results are subjective, not accurate enough, and cannot provide detailed quantitative data. ② The operation of the ruler measurement method is also simple and easy to perform, and relatively accurate data can be measured. Currently, standard calipers or vernier calipers are mainly used for the distance measurement. However, because ordinary vernier calipers cannot accurately fit the edge of the rectus abdominis muscle, the measurement results also have a certain degree of subjectivity and are not accurate enough.
[0007] Therefore, in order to measure the rectus abdominis muscle distance more accurately and reduce the medical cost, the present utility model proposes a special portable detection ruler for the distance of diastasis recti abdominis. Summary of the Utility Model
