“…A tight iliopsoas may contribute to a lack of hip extension during the heeloff and toe-off phases of gait, decreasing stride length. To compensate, the pelvis may rotate anteriorly, hyperextending the spine [36] to increase stride length [7]. This may lead to microtrauma of the sacroiliac joints and lumbar spine, possibly leading to hypermobility in the lumbar spine and resultant LBP [37].…”

“…In general, specific strength and length variables were selected because muscle imbalances may cause abnormal biomechanics, which may then cause compensatory movements, leading to microtrauma in the pelvis and lumbar spine [7]. Because of the linking of the pelvis, torso, and lower limbs in gait, repetitive strain injury to the lumbosacral spine is possible with improper or altered gait [23].…”

“…Because of the linking of the pelvis, torso, and lower limbs in gait, repetitive strain injury to the lumbosacral spine is possible with improper or altered gait [23]. We chose muscles that function in the sagittal plane of motion for this study, because they have been shown to be important in gait after LLA [18,24] and in the development of lumbar lordosis [7].…”

For this study, we compared the physical impairments and functional deficits of individuals with lower-limb amputation (LLA) for those with and without low back pain (LBP). Nineteen participants with LLA were placed into two groups based on visual analog scores of LBP. We assessed functional limitations, iliopsoas length, hamstring length, abdominal strength, back extensor strength, and back extensor endurance. Data analysis included correlations and t-tests. We found significant correlations between pain score and functional limitations, iliopsoas length, and back extensor endurance. We also detected significant differences in functional limitations, iliopsoas length, back extensor strength, and back extensor endurance between those with and without LBP. We saw significant differences in back extensor strength and back extensor endurance between those with transtibial and transfemoral amputations. Differences exist in physical measures of individuals with LLA with and without LBP. Clinicians should consider these impairments in individuals with amputation who experience LBP. Because of the participants' characteristics, these findings may be applicable to veterans with LLA.Abbreviations: ANOVA = analysis of variance, LBP = low back pain, LLA = lower-limb amputation, NYIT IRB = New York Institute of Technology Institutional Review Board, PKE = passive knee extension, SD = standard deviation, SPSS = Statistical Package for the Social Sciences, VAS = visual analog scale.

“…1 Unnatural biomechanics of foot reduces the foot ability to do normal performance. 3 Pronated foot is on the most common reasons of people's referring to orthopedics and clinics as seen in a wide range of deformities such as reduction of medial longitudinal arch height, heel external rotation and anterior foot abduction. 4 It is generally believed that pronated foot acts as a facilitator in bringing about overtraining damages and pathologic conditions such as plantar fasciitis, Achilles tendon shortening, stress fracture, shin splint and pain in heel, knee and back.…”

Changes in anatomical structure of the foot reduce the foot ability for normal performance. This study aimed to compare selected muscles of trunk and lower extremities during walking in individuals with different foot types. Forty-five female students were categorized into three groups depending on their foot structures namely, pronated, supinated and normal feet. Foot types defined by foot posture index and X-ray under the specialist physician. Electromyography activities were recorded from muscles of tibialis anterior, peroneus longus, medial gastrocnemius, biceps femoris, gluteus medius, external oblique and erector spinae in three groups while walking in determined path with self-selected gait speed. Each effort simultaneous with electromyography registration was recorded with camera. One-way ANOVA test was used to compare the groups at significance level of 0.05. The activity of muscle of tibialis anterior and medial gastrocnemius was greater in pronated foot group than that in supinated and normal groups during heel contact phase of gait (p = 0.001). Supinated foot group exhibited a greater peroneus longus activation than the other groups (p = 0.001). No significant differences were observed for remaining four muscles (p > 0.05). During midstance phase, peroneus longus, supinated foot group exhibited a greater activity compared to other groups while pronated foot group exhibited a greater muscle activity for gluteus medius than others (p = 0.001). There was a significant difference between normal and pronated foot groups for external oblique (p = 0.001). Regarding the findings of this study, the muscular performance changes in pronated and supinated foot groups are more noticeable than that in normal foot type. downloaded from http://www.apunts.org, day 07/04/2016.

PALABRAS CLAVEMúsculos de las extremidades inferiores; Marcha; Pie neutro; Pie pronador; Pie supinador Comparación de la actividad muscular seleccionada del tronco y las extremidades inferiores en la forma de caminar de las mujeres jóvenes con pies supinadores, pronadores y neutrosResumen Los cambios en la estructura anatómica del pie reducen su capacidad de rendimiento normal. Este estudio trató de comparar los músculos seleccionados del tronco y las extremidades inferiores al caminar, en personas con diferentes tipos de pie. Se clasificó a 45 estudiantes femeninas en tres grupos, dependiendo de la estructura de sus pies, es decir, pronadora, supinadora y neutra. El médico especialista definió los tipos de pie mediante el índice postural del pie y rayos X. Se registraron las actividades electromiográficas de los músculos tibial anterior, peroneo lateral largo, gemelo interno, bíceps femoral, glúteo medio, externo oblicuo y erector de la columna en los tres grupos, al realizar un recorrido determinado, con una velocidad de marcha auto-seleccionada. Se grabó con una cámara cada esfuerzo simultáneo al registro electromiográfic...
