“…e abductor hallucis muscle has been gaining prominence in the most recent publications on plantar pain [10,11]. It is a superficial, triangular, flat, bipenniform muscle that fills the foot medial arch and is responsible for sustaining the arch and hallux abduction and flexion [12,13]. e muscle originates from flexor retinaculum, medial process of the calcaneus tuberosity, and intermuscular septum between itself and flexor hallucis brevis; the insertion is into the medial aspect of the proximal hallux phalanx, the collateral ligament of the proximal metatarsophalangeal joint, and the medial sesamoid bone [14,15].…”

Myofascial pain syndrome is characterized by pain and a limited range of joint motion caused by muscle contracture related to motor-end-plate dysfunction and the presence of myofascial trigger points (MTrPs). It is the most frequent cause of musculoskeletal pain, with a worldwide prevalence varying between 13.7% and 47%. Of the patients with myofascial pain syndrome, approximately 17% have pain in the medial hindfoot area. The abductor hallucis muscle is located in the medial, posterior region of the foot and is related to painful plantar syndromes. The objective of this study was to describe the distribution of the medial plantar nerve and their anatomical relationship with MTrPs found in the literature. Thirty abductor hallucis muscles were dissected from 15 human cadavers (8 males and 7 females). The muscles were measured, and the distribution data of the medial plantar nerve branches in each quadrant were recorded. For statistical analysis, we used generalized estimation equations with a Poisson distribution and a log logarithm function followed by Bonferroni multiple comparisons of the means. The data are expressed as the mean ± standard deviation. The level of significance was adjusted to 5% (p<0.05). A high concentration of nerve branches was observed in the first quadrant (Q1) of the abductor hallucis muscle, which is the same area in which the MTrPs are described. The topography of the entry points of the branches of the medial plantar nerve to the abductor hallucis muscle correlates with the topography of the muscular trigger points. The anatomical structure of the MTrPs may be useful for a better understanding of the pathophysiology of myofascial disorders and provide a basis for surgical and clinical treatments.

“…Several authors have suggested that the pressure exerted on medial side of the foot and capsule of the irst metatarsophalangeal joint may cause development and progression of HV deformity [12,23]. Therefore, we aimed to determinate how much the amount of navicular drop would affect the HV angular severity and foot-speci ic health related quality of life in this study.…”

“…Furthermore, the ND measurement is a practical technic for understanding the biomechanical relationship between the foot deformity and MLA structures [12]. The normal value of ND test was accepted 6 mm, value of 9 mm or more was considered high and values less than 6 mm were considered low [24,25].…”

“…Unsuitable footwear, excessive weight-bearing as extrinsic factors and age, genetics, female gender, joint hyper mobility, ligamentous laxity, speci ic foot deformities (pes planus, metatarsal primus varus) as intrinsic factors lead to the development of HV [9,10]. Navicular drop (ND) is a chronic condition characterized by inadequate support of the medial longitudinal arch (MLA) and extreme subtalar joint pronation of the foot [11,12]. Previous studies have reported that collapse of MLA and an excessively pronated foot is associated with HV [9,13].…”

The purpose of this study was to determine the relationship between Navicular drop (ND) and Hallux valgus (HV) angles and their effects on foot-specifi c health related quality of life. Sixty female patients with bilateral HV aged between 32-60 participated in this study. The patients with the HV deformity degree of "2" or "3" according to the Manchester scale were included.HV angle were obtained from standing (weight bearing) bilateral antero-posterior radiographs. HV angle (A angle), intermetatarsal angle (B angle), hallux interphalangeal angle (C angle) were measured. Subtalar pronation was measured the navicular drop (ND) test. ND test were performed for both feet and recorded in millimeters. Foot-specifi c health related quality of life was measured using the Manhester-Oxford Foot Questionnaire (MOFQ).There was a strong positive correlation between the ND qtest and the angles A, B, and C for the right foot (rho=0.749, 0.761 and 0.749 p<0.001, respectively,). There was a strong positive correlation between the MOFQ subscales and the angles A, B, and C for the right foot (p<0.001). There was a strong positive correlation between the MOFQ subscales and the angles A, B, and C for the right foot (p<0.001).In conclusion, there were relationship between ND, HV angular severity and foot-specifi c health related quality of life. As the HV angular severity increased, there was greater drop in the navicula and reduction in quality of life.

“…After the examinee sat in and maintained the subtalar neutral position, the examiner palpated the navicular tuberosity of the examinee, measured the height of the navicular bone using measurement equipment, and asked the examinee to stand on both feet. Then, the examiner measured again the height of the navicular bone and calculated the difference between the two measured values to obtain the result of the navicular drop test (NDT) 10 , 11 , 12 ) . In this study, a vernier height gauge (506-207; Mitutoyo, Kawasaki Japan) was used to measure NDT.…”

[Purpose] The aim of this study was to evaluate the structural deformity of the foot joint on the affected side in hemiplegic patients to examine factors that affect this kind of structural deformity. [Subjects and Methods] Thirty-one hemiplegic patients and 32 normal adults participated. The foot posture index (FPI) was used to examine the shape of the foot, the modified Ashworth scale test was used to examine the degree of ankle joint rigidity, the navicular drop test was used to investigate the degree of navicular change, and the resting calcaneal stance position test was used to identify location change of the heel bone. [Results] The FPIs of the paretic side of the hemiplegic patients, the non-paretic side of the hemiplegic patients, and normal participants were −0.25 ± 2.1, 1.74 ± 2.3, and 2.12 ± 3.4 respectively. [Conclusion] Our findings indicated that in stroke-related hemiplegic patients, the more severe the spasticity, the more supinated the foot. Further, the smaller the degree of change in the navicular height of hemiplegic patients is, the more supinated the paretic side foot is. Additionally, a greater change in the location of the calcaneus was associated with greater supination of the overall foot.
