Rearfoot Eversion

The purpose of this study was to determine the proportion of available passive frontal plane rearfoot motion that is used during the stance phase of walking. Data were collected from 40 healthy, asymptomatic volunteer subjects (20 men and 20 women) aged 23 to 44 years. Passive inversion and eversion motion was measured in a nonweightbearing position by manually moving the calcaneus. Dynamic rearfoot motion was referenced to a vertical calcaneus and tibia and was measured using a three-dimensional electromagnetic motion-analysis system. The results indicated that individuals used 68.1% of their available passive eversion range of motion and 13.2% of their available passive inversion range of motion during walking. The clinical implication of individuals’ regularly operating at or near the end point of their available rearfoot eversion range of motion is discussed. (J Am Podiatr Med Assoc 95(4): 376–382, 2005)

Rearfoot Motion

Background: Classification of rearfoot motion patterns would assist in understanding normal rearfoot motion and would facilitate the identification of abnormal motion. We sought to identify common frontal plane rearfoot motion patterns in an asymptomatic population. Methods: Frontal plane rearfoot motion was measured with an electromagnetic motion analysis system in 279 asymptomatic individuals during barefoot walking. The coefficient of multiple correlation and visual observation were used to identify similar patterns of rearfoot motion. Results: Four distinct rearfoot motion patterns were identified: pattern 1 consisted of 176 individuals (63.1%) and was labeled “typical” eversion, pattern 2 consisted of 87 individuals (31.2%) and was labeled “prolonged eversion,” pattern 3 consisted of nine individuals (3.2%) and was labeled “delayed eversion,” and pattern 4 consisted of seven individuals (2.5%) and was labeled “early eversion.” Conclusions: Asymptomatic frontal plane rearfoot motion can be classified into four distinct patterns, but most individuals (94.3%) exhibit one of two motion patterns (typical or prolonged eversion).

The kinematic and kinetic differences between two styles of stair climbing, namely regular stair climbing (RSC) and lateral stair climbing (LSC), was studied. A four-step wooden stair instrumented with two force plates was used as the action platform. The kinematic and kinetic recordings were collected using a 6-camera, 2-force plate commercial three-dimensional motion analysis system. The LSC activity was subdivided into LSCL activity, where the right leg was the leading leg, and LSCT.

Discernible Difference

Background: A variety of shoe modifications have been used to reduce the forces applied on the plantar surface of the foot in those with diabetes. Toe and heel rockers are 2 of the most common types used. The aim of this study is to evaluate the effect of these shoe modifications on the kinematics of both normal and diabetic individuals. Method: Two groups of healthy and diabetic individuals were recruited for this study. The Qualysis motion analysis system was used to record the motions of participants while walking with shoes with toe and a combination of toe and heel rockers (combined). The effects of the type of rockers used and the effect of groups were determined using MANOVA. Results: Results of the study demonstrated no discernible difference between the spatiotemporal and range of motion of the ankle, knee, and hip joints while walking with a toe and combined rockers. There was also no difference between healthy and diabetic individuals in relation to these parameters (P value >.05). Conclusion: Results of this study demonstrated no difference between the spatiotemporal and range of motion of lower-limb joints in healthy and diabetic individuals when walking with toe and combined rockers. Because the use of these rockers did not influence the kinematics of the joints while walking, it is recommended that they be used for this group of individuals if they influence the forces applied on the foot.

Amputee Gait

The ability to objectively measure an amputee's walking activity over prolonged periods can provide clinicians with a useful means of evaluating their patients' outcomes. The present study aimed to validate the temporospatial data output from a commercially available ambulatory activity monitor (PAM, Össur) fitted to trans-tibial and trans-femoral amputees, against data that was simultaneously captured from a three dimensional motion analysis system (Qualisys Medical AB, Gothenburg, Sweden). Results indicate that the PAM monitor provides accurate measures of temporospatial aspects of amputee gait for walking speeds above 0.75 m/s.

Rearfoot Motion

The purpose of this study was to investigate whether the amount of ankle passive dorsiflexion range of motion influences the pattern of frontal plane rearfoot motion during walking. Three-dimensional motion of the rearfoot was measured in two groups of subjects, those with ankle passive dorsiflexion range of motion less than or equal to 10 degrees, and those with ankle passive dorsiflexion range of motion greater than 15 degrees, while they walked along a 6.1-m walkway. The results indicated that the only statistically significant differences between the two groups were in the time to reinversion of the rearfoot and the time to heel-off. Slight-to-moderate limitation of ankle passive dorsiflexion range of motion significantly alters the timing, but not the magnitude, of frontal plane rearfoot motion during walking.
