“…142 Koldenhoven et al 143 observed that patients with CAI had greater stride-to-stride variability in the location of their center of pressure during the first 10% of stance phase during walking compared with controls but no differences later in the stance phase, despite their center of pressure staying more lateral. 144 Interestingly, the patients with CAI also exhibited less variability in electromyographic amplitude of the fibularis longus muscle throughout the swing phase and the beginning of the stance phase. 143 During cutting tasks requiring rapid lateral movement, patients with CAI activated the fibularis longus earlier than healthy controls, in a manner similar to that seen while walking.…”

Lateral ankle sprains (LASs) are among the most common injuries incurred during participation in sport and physical activity, and it is estimated that up to 40% of individuals who experience a first-time LAS will develop chronic ankle instability (CAI). Chronic ankle instability is characterized by a patient's being more than 12 months removed from the initial LAS and exhibiting a propensity for recurrent ankle sprains, frequent episodes or perceptions of the ankle giving way, and persistent symptoms such as pain, swelling, limited motion, weakness, and diminished self-reported function. We present an updated model of CAI that aims to synthesize the current understanding of its causes and serves as a framework for the clinical assessment and rehabilitation of patients with LASs or CAI. Our goal was to describe how primary injury to the lateral ankle ligaments from an acute LAS may lead to a collection of interrelated pathomechanical, sensory-perceptual, and motor-behavioral impairments that influence a patient's clinical outcome. With an underpinning of the biopsychosocial model, the concepts of self-organization and perception-action cycles derived from dynamic systems theory and a patient-specific neurosignature, stemming from the Melzack neuromatrix of pain theory, are used to describe these interrelationships.

“…increase the risk of recurrent lateral ankle sprains by placing the foot in a more vulnerable position when it is combined with the kinetic gait profiles of patients with CAI who have a laterally deviated center of pressure (COP) of the foot throughout the gait cycle. [9][10][11] Whereas the kinematic gait profiles have been consistent among studies, [2][3][4][5][6][7][8] the muscle-activity gait profiles of patients with CAI have been inconsistent. For example, Hopkins et al 9 observed increased tibialis anterior and peroneus longus activation during stance in patients with CAI.…”

Context The literature on gait kinematics and muscle activation in chronic ankle instability (CAI) is limited. A comprehensive evaluation of all relevant gait measures is needed to examine alterations in gait neuromechanics that may contribute to recurrent sprain. Objective To compare walking neuromechanics, including kinematics, muscle activity, and kinetics (ie, ground reaction force [GRF], moment, and power), between participants with and those without CAI by applying a novel statistical analysis to data from a large sample. Design Controlled laboratory study. Setting Biomechanics laboratory. Patients or Other Participants A total of 100 participants with CAI (49 men, 51 women; age = 22.2 ± 2.3 years, height = 174.0 ± 9.7 cm, mass = 70.8 ± 14.4 kg) and 100 individuals without CAI serving as controls (55 men, 45 women; age = 22.5 ± 3.3 years, height = 173.1 ± 13.3 cm, mass = 72.6 ± 18.7 kg). Intervention(s) Participants performed 5 trials of walking (shod) at a self-selected speed over 2 in-ground force plates. Main Outcome Measure(s) Three-dimensional GRFs, lower extremity joint angles, internal joint moments, joint powers, and activation amplitudes of 6 muscles were recorded during stance. Results Compared with the control group, the CAI group demonstrated (1) increased plantar flexion or decreased dorsiflexion, increased inversion or decreased eversion, decreased knee flexion, decreased knee abduction, and increased hip-flexion angles; (2) increased or decreased inversion, increased plantar flexion, decreased knee extension, decreased knee abduction, and increased hip-extension moments; (3) increased vertical, braking, and propulsive GRFs; (4) increased hip eccentric and concentric power; and (5) altered muscle activation in all 6 lower extremity muscles. Conclusions The CAI group demonstrated a hip-dominant strategy by limiting propulsive forces at the ankle while increasing force generation at the hip. The different walking neuromechanics exhibited by the CAI group could represent maladaptive strategies that developed after the initial sprain or an injurious gait pattern that may have predisposed the participants to their initial injuries. Increased joint loading and altered kinematics at the foot and ankle complex during initial stance could affect the long-term health of the ankle articular cartilage.

“…Although fibular spasticity is not well-known clinically, several related studies have been reported in medical literature (Xu et al, 2015;Laddha et al, 2016;Santamato et al, 2019). Louwerens et al (1995) and Koldenhoven et al (2016) reported that hyperactivity of the fibularis muscle-which plays an important role in maintaining balance while walking-causes an imbalance during the stance phase and increases walking speed. Thevenon et al (2013) reported that spasticity of the fibularis longus can cause foot clonus.…”

This study used a modified Sihler's staining method to analyze the nerve distributions of the fibularis muscle to identify the most effective sites for botulinum toxin injection for fibular spasticity treatment. Ten specimens of the fibularis longus and brevis were obtained bilaterally from five fixed cadavers. The applied method of modified Sihler's staining was designed to reveal the intramuscular nerve distribution of the fibularis muscles. We divided the fibularis muscles into four quarters, which were defined as Sections 1–4 starting from the proximal part of the leg. There were one, two, and three nerve entry points in one (10%), six (60%), and three (30%) of the fibularis longus specimens, respectively, and in four (40%), five (50%), and one (10%) of the fibularis brevis specimens, respectively. We counted the number of nerve endings in each section: 321 and 195 points were identified in the fibularis longus and brevis, respectively. The densities of nerve endings were highest in Section 2 of the fibularis longus (147 of 321, 46%) and in Section 3 of the fibularis brevis (78 of 195, 40%). The landmarks used in this study (the fibular head and lateral malleolus) are easily palpable on the skin's surface, allowing clinicians to target the effective injection site (Section 2) without requiring ultrasound guidance, especially for the fibularis longus.
