Hip Pain
Published in Benjamin Apichai, Chinese Medicine for Lower Body Pain, 2021
The muscles of the femoral adductor are composed of five muscles on the inner side of the femur. The superficial layer from the outside to the inside is the pectineus muscle, the adductor longus muscle, and the gracilis muscle. The deep side of the adductor longus muscle and the pectineus muscles are adductor brevis muscles, and the deep muscles of the muscles are the adductor magnus muscles, which are triangular.
The Mechanics of Gait

The three hip adductors have other significant roles. Hip extension is the major role of the adductor magnus. Both the adductor longus and gracilis are hip flexors. One assumes the unrecorded adductor brevis functions with the adductor longus.

During gait analysis, a gait is divided into eight gait events, including of heel strike, foot flat, midstance, heel off, toe off, acceleration, midswing, and deceleration (Bai and Shang 2010). There are two main methods for muscle modeling. This article mainly uses linear muscles to replace the physical model of muscles to establish the musculoskeletal system model. The default coordinate system and orientation of each minutia (Zhao et al. 2016) is the same as that of the CT machine. And totally 11 muscle models were constructed, including the Adductor longus, Adductor magnus, Adductor brevis, Vastus medialis, Vastus lateralis, Iliopsoas, Gluteus minimus, Gluteus medius, Gluteus maximus, Gastrocnemius lateralis, and Gastrocnemius medialis (Bai and Shang 2010; Ali Banijamali et al. 2015). The model of the musculoskeletal linear hip joint is shown in Figure 3 and the muscle force on the femur is shown in Table 2.

These systems utilized electrodes that delivered stimulating current to the nerves innervating the trunk and hip extensor muscles important for seated stability. Intramuscular electrodes45 were inserted at L1-L2 level spinal nerves to recruit the lumbar paraspinal muscles for trunk extension. Two participants (S1, S2) had electrodes placed at T12-L1 to activate the quadratus lumborum for medial-lateral stability. Epimysial46 or intramuscular electrodes were inserted or sutured at the motor points of the gluteal and hamstring muscles for hip extension. In some subjects, intramuscular electrodes were placed in the posterior portion of the adductor magnus to assist with thigh adduction as well as for hip extension. In one subject (S2), surface stimulation was applied for two muscles (right erector spinae and left quadratus lumborum) to augment the responses of the implanted electrodes. Subject demographics and the configuration of each system are summarized in Table 1.

The rectus abdominis, adductor longus, adductor magnus, adductor brevis, and gracilis are also reported as the sources of groin pain in at least 10% of cases (Hölmich et al., 2014; Serner et al., 2015). Typical diagnosis is based on palpation of the muscle region and resisted muscle activation (Brix, Lohrer, and Hoeferlin, 2013; Hölmich et al., 2014). When the injured muscle is unknown, “athletic pubaglia”, sometimes referred to as “groin disruption” is the medical diagnosis typically given. Athletic pubalgia is described as posterior abdominal wall weakening and the conjoined tendon separates, without evidence of a hernia on imaging or a palpable defect (Garvey and Hazard, 2014; Sheen et al., 2014). Pain occurs with exertion, Valsalva’s maneuver, resisted hip adduction, pressure, and a partial sit up, but not with coughing or sneezing (Meyers et al., 2000; Morelli and Smith, 2001). Outcomes for return to pre-injury level often require surgical repair due to poor outcomes reported with conservative management (Elattar, Choi, Dills, and Busconi, 2016; Morelli and Smith, 2001).
