A Study to Analyse the Effectiveness of Physical Therapy and Wedged Foot Orthotic  Devices on Pain in Runners with Pronated Foot

Background: Motion control and comfort are primary objectives in orthotic intervention. Semicustom orthotic devices have been presented as a more cost-effective solution than custom orthotic devices. However, no studies have compared their function or comfort to that of custom orthotic devices. Methods: Nineteen uninjured runners were fitted for custom and semicustom orthotic devices. Subjects underwent an instrumented gait analysis of running and walking in no-orthotic, custom orthotic, and semicustom orthotic conditions. Subjects completed visual analog scales for the custom and semicustom orthotic conditions. One-way repeated measures analyses of variance were performed on the rearfoot variables of peak eversion, eversion excursion, eversion duration, and eversion velocity. Two-tailed, dependent t tests were used to compare comfort. Results: Eversion excursion showed significant differences between the conditions: during running, it was reduced in the custom orthotic as compared to the no-orthotic condition; during walking, it was reduced in the semicustom orthotic as compared to both the custom and no-orthotic conditions. The custom orthotic devices were significantly more comfortable (P < .05) than the semicustom devices in the area of the edges only. Conclusion: The results suggest that, in uninjured individuals, there are few differences in rearfoot motion control and comfort between the custom and semicustom orthotic devices used in this study.

The purpose of this study was to examine the effects of laterally wedged foot orthotic devices, used to treat knee osteoarthritis, on frontal plane mechanics at the rearfoot and hip during walking. Thirty individuals with diagnosed medial knee osteoarthritis were recruited for this study. Three dimensional kinematics and kinetics were recorded as the subjects walked in the laboratory at an intentional walking speed. Peak eversion, eversion excursion and peak eversion moment were increased while the peak knee adduction moment was reduced in the laterally wedged orthotic condition compared to the no wedge condition. In contrast, no changes were observed in the variables of interest at the hip. There was no significant relationship between the change in the peak frontal plane moment at the rearfoot and change in the peak frontal plane moment at the knee or hip as a result of the lateral wedge. Laterally wedged foot orthotic devices, used to treat knee osteoarthritis, do not influence hip mechanics. However, they do result in increased rearfoot eversion and inversion moment. Therefore, a full medical screen of the foot should occur before laterally wedged foot orthotic devices are prescribed as a treatment for knee osteoarthritis.

Analyze Data

The purpose of this study was to evaluate the effectiveness of two different rigid foot orthotic devices in controlling subtalar joint subluxation and pronation. A high-speed video analysis system was used to record, store, and analyze data from seven runners: 1) barefoot, 2) shoes only, 3) shoes and vertical orthoses, and 4) shoes with 25 degrees inverted orthotic devices. The results indicate the need for suitable studies, on a larger population group, to evaluate the effect of a variety of orthotic devices on running biomechanics.

Sports Activities

The incidence of fifth metatarsal fracture is somewhat common in sports and can be complicated in nature. Fractures of the fifth metatarsal can occur at a number of locations. Although some of these fractures respond well to conservative treatment, others have been notoriously hard to heal, with high rates of nonunions and other complications. Foot orthotic devices are commonly used as aids in the treatment of foot problems. In our case, we considered the combined effect of the surgical treatment and application of the custom-made foot orthoses. Special attention was taken with adjustments to the orthotic devices along and beneath the affected regions of the foot for adequate pain management and quick recovery to return to normal sports activities. Requirements for computer aided design/computer aided manufacturing orthotic design and manufacturing in this case were specific and considerably different from the usual procedure.

Foot Orthotic

One hundred thirty-two female basketball players were observed for lower-extremity overuse injury between 1993 and 2004. Athletes studied between 1993 and 1996 did not receive foot orthotic devices and composed the control group. The treatment group comprised athletes studied between 1996 and 2004. Athletes in the treatment group were given a foot orthotic device before participation in basketball. Data analysis included lower-extremity overuse injury rates and the effect of foot orthotic devices on lower-extremity overuse injury rates by means of an incidence density ratio. The control group had a lower-extremity overuse injury rate of 5.37 per 1,000 exposures, and the treatment group had a rate of 6.44 per 1,000 exposures. The incidence density ratio was not significant (P = .44). This study rejects the concept that foot orthotic devices may assist in prevention of lower-extremity overuse injury in female basketball players. (J Am Podiatr Med Assoc 96(5): 408–412, 2006)
