Effectiveness of a Commercially Available Orthotic Insert
Sonia N Young et al
Int J Neurorehabilitation 2016, 3:2 (full text)

Background: Foot pain is a non-specific complaint among individuals who stand for extended periods of time.
Prefabricated inserts have been effective for increasing balance and managing pain. One manufacturer has
developed a line of general inserts for that purpose. The purpose of this study was to examine the effectiveness of a
commercially available orthotic insert on balance, pain, and plantar foot pressures as well as to determine if
enhancing balance may decrease pain.
Methods: Twenty-three subjects with at least 6 months non-specific foot pain participated and were issued a
commercially available orthotic insert after screening. The Sensory Organization Test composite score was used to
assess balance on the NeuroCom? Balance Manager SMART EquiTest. Foot Function Index (FFI) and Numeric
Pain Rating Scale (NPRS) were used to assess pain. GAITRite was utilized to assess plantar foot pressures.
Results: Foot pain was decreased after one week with use of the commercially available orthotic insert.
Increased balance scores were noted between day 1 without inserts and after day 7 of insert wear and also between
day 1 with inserts and day 7. Decreases in pain were noted between pre balance testing without inserts (day 1) and
after day 7 as well as immediately after balance testing with inserts (day 1) and day 7. Among the females, right
lateromedial foot pressures increased from day 1 without inserts and immediately after the addition of inserts. An
inverse relationship was observed between the NPRS and the composite balance scores after 1 week of insert wear.
Conclusions: Results indicate that a commercially available orthotic insert may be effective in managing foot
pain and increasing balance after one week. Additionally, inserts appear to shift the right foot pressures from the
predominately medial aspect of the foot to the lateral aspect of the foot for females but not males.

Comparison of Two Types of Insoles on Musculoskeletal Symptoms and Plantar Pressure Distribution in a Work Environment: A Randomized Clinical Trial.
Almeida JS et al
Clin Med Res. 2016 May 26

BACKGROUND:
the aim of the present study was to assess plantar pressure distribution and musculoskeletal symptoms following the use of customized insoles among female assembly line workers.
METHODS:
twenty-nine female assembly line workers (age: 29.76 ? 5.79 years; weight: 63.79 ? 12.11 kg) with musculoskeletal symptoms and who work predominantly while standing participated in the study. The Nordic Musculoskeletal Questionnaire was administered for the sample selection. Plantar pressure was determined using a computerized plantar pressure feedback system. A control group (13 individuals) used ethylvinylacetate insoles (Podally) that were individually heat-molded and heat-glued. The intervention group (14 individuals) also used the insoles and a strip of the same material was added to the site of greatest plantar pressure, as determined by the electronic feedback device. After five weeks, the plantar pressure data were collected again and the questionnaire was administered second time.
RESULTS:
there was no significant difference between groups with regard to pain in any anatomic site. Within each group, however, the lumbar region exhibited a reduction in symptoms in the intervention group (p<0.05) and the feet exhibited a reduction in symptoms in both groups (p<0.05). Mean plantar pressure increased and plantar surface decreased in the intervention group (p<0.05).
CONCLUSIONS:
insoles increased the feet comfort in both groups and added strip did not either significantly modified the plantar pressure or the other symptoms in female workers.
