Thin customized insole for pain relief and walking ability in rheumatoid arthritis (RA)

Around 1% of world's population suffers from rheumatoid arthritis (RA). People between 40 – 65 years are prone to RA with women three times more likely to get affected as compared to men.  The study mentioned here was performed with an objective to analyze the immediate effects of a thin, easily customizable insole on pain and walking ability of RA patients, who have forefoot pain. It even determined whether the insoles were in use one year afterwards.

Linberg GH used an experimental, assessor-blinded design for comparing the immediate effects after walking with or without insoles randomly. A structured telephone interview was conducted after one year.

This study included 21 subjects suffering from RA and had foot pain in at least one forefoot while walking and in response to the Ganslen test. They were consecutively recruited from the outpatient clinic and the inpatient ward at a hospital for people with rheumatic disease. Every subject received 4-mm thin and individually customized insole. These soles were made up of malleable plastic material with synthetic textile material on the upper side.

A 6-min walk test (6MWT) evaluated the ability to walk. The 10-cm visual analogue scale (VAS) was used for measuring the intensity of foot pain induced during walking with and without the insole. A standardized questionnaire having five items was used to find out the usage of, level of satisfaction with, insoles after one year.

The findings of the study revealed that the median (interquartile range) intensity of foot pain with insoles was 19 (15) and without insoles, it was 36 (27). Statistically, no significant differences were observed in 6MWT between the presence or absence of insoles (p = 0.07). After one year, the participants still using the insoles were about 90%.

This study culminated that the use of thin, easily customizable insoles, were able to provide immediate and clinically relevant relief from forefoot pain induced while walking. Even after a year most of the patients were still using these insoles.
