“…51 Schmidt et al 49 found that individuals with CAI also exhibited slower loading responses of the lateral and medial rearfoot and the medial midfoot during jogging. When comparing individuals with CAI and individuals who sustained isolated ankle sprains but had no subsequent feelings of instability during running, Morrison et al 16 showed that individuals with CAI presented with a more lateral COP of the rearfoot at foot strike and a more lateral COP trajectory during loading. Both the lateral COP and slower loading responses could suggest that a neuromuscular response occurs in individuals with CAI to maintain a functional ''close-packed'' supinated position of the subtalar and midfoot joints.…”

“…Investigators have identified specific deficits in proprioception, 10,11 peroneal reaction time, 12,13 and postural control 14,15 in individuals with CAI. Alterations in lower extremity kinematics during gait [16][17][18][19] and jump landings 20,21 also are evident in individuals with CAI, whereas strength deficits are controversial. [22][23][24][25][26] It is unclear whether these deficits and alterations occur in individuals before or after an initial ankle sprain.…”

Context: Ankle sprains are among the most common musculoskeletal injuries, and many individuals with ankle sprains develop chronic ankle instability (CAI). Individuals with CAI exhibit proprioceptive and postural-control deficits, as well as altered osteokinematics, during gait. Neuromuscular activity is theorized to play a pivotal role in CAI, but deficits during walking are unclear.Objective: To compare motor-recruitment patterns as demonstrated by surface electromyography amplitudes between participants with CAI and healthy control participants during walking.Design: Descriptive laboratory study. Setting: Laboratory.Patients or Other Participants: Fifteen adults with CAI (5 men, 10 women; age ¼ 23 6 4.2 years, height ¼ 173 6 10.8 cm, mass ¼ 72.4 6 14 kg) and 15 matched healthy control adults (5 men, 10 women; age ¼ 22.9 6 3.4 years, height ¼ 173 6 9.4 cm, mass ¼ 70.8 6 18 kg).Intervention(s): Participants walked shod on a treadmill while surface electromyography signals were recorded from the anterior tibialis, peroneus longus, lateral gastrocnemius, rectus femoris, biceps femoris, and gluteus medius muscles.Main Outcome Measure(s): Preinitial contact amplitude, postinitial contact amplitude, time of activation relative to initial contact, and percentage of activation time across the stride cycle were calculated for each muscle.Results: Time of activation for all muscles tested occurred earlier in the CAI group than in the control group. The peroneus longus was activated for a longer duration across the entire stride cycle in the CAI group (36.0% 6 10.3%) than the control group (23.3% 6 22.2%; P ¼ .05). No differences were noted between groups for measures of electromyographic amplitude at either preinitial or postinitial contact (P . .05).Conclusions: We identified differences between the CAI and control groups in the timing of muscle activation relative to heel strike in multiple lower extremity muscles and in the percentage of activation time across the entire stride cycle in the peroneus longus muscle. Individuals with CAI demonstrated neuromuscular-activation strategies throughout the lower extremity that were different from those of healthy control participants. Targeted therapeutic interventions for CAI may need to be focused on restoring normal neuromuscular function during gait.

“…These alterations have been hypothesized to play a role in force absorption and production and associated plantar pressure research has identified differences in the center of pressure during gait [68]. Compared to healthy subjects, CAI patients have been found to have a more laterally situated center of pressure during gait [69,70]. More complex analysis of movement has found more sensitive alterations in joint coupling around the ankle [47].…”

Lateral ankle sprains occur more than any other musculoskeletal injury in an athletic population. The greatest risk for an inversion ankle sprain is a history of a previous sprain. Recurring instability associated with subjective complaints of giving way is often termed chronic ankle instability (CAI). CAI has been associated with altered postural control, sensorimotor deficits, reduced physical activity, functional limitations, and long-term degeneration of the joint. Alterations, including muscle activity and changes in the kinematics of the lower extremity may predispose this population to continued instability at the joint and long term health issues. Common treatments include using external support, therapeutic modalities, and directed rehabilitation. Wearing ankle braces and performing balance training has been shown to reduce the risk of recurrent ankle sprains. Directed rehabilitation may improve function in patients with CAI. By identifying and minimizing dysfunction following ankle sprains, clinicians may improve the short-term and longterm function of this population.

“…Más autores analizaron las presiones plantares donde sugieren que el grupo con Inestabilidad crónica tiene mayores presiones plantares laterales y ello es un factor que predispone a la inestabilidad lateral 16,17,18 , sin embargo, en un estudio de Huang PY, vieron un cambio del cop de lateral a medial más rápido en pacientes con inestabilidad así como un mayor pico de presión en M1, que suelen ser indicadores de pronación del pie por colapso del arco longitudinal interno. Roel De Ridder, contradice esta distribución de presiones más lateral 16,17,18 en pacientes con Inestabilidad cró-nica 19 y T. Willems et al hallaron mayor presión bajo la zona medial del pie, un retraso en la flexión de rodilla máxima, una resupinación retrasada en la fase de propulsión, un despegue por zona lateral y no por el hallux, un tiempo total de apoyo del pie más largo que el grupo control, un mayor rango de movimiento en 1ª metatarsofalángica 20 , todo ello sugiere un aumento de momentos pronadores. Los factores de riesgo anatómicos que se encuentran asociados a la aparición de un esguince lateral, son principalmente el rango de eversión calcánea en mujeres y el incremento de inclinación del astrágalo en hombres 20 .…”

Plantar Pressure During Running in Subjects With Chronic Ankle Instability

Abstract: Clinicians treating patients with CAI should consider providing interventions to decrease the amount of rearfoot inversion at FS and during loading in order to create a more medial COP trajectory upon impact.
