Brief Summary

Non-specific low back pain is a common condition. Insoles are one of the many treatment form for chronic nonspecific LBP. The investigators hypothesized the contact total insole group will present pain reduction and functional improvement. The aim of this study is to assess the effectiveness of contact total insole for people with nonspecific chronic low back pain and the impact of this insole on function, quality of life, load distribution in the plantar region, gait variables and satisfaction with insole use.

Outcome Measures

Primary Outcomes (1)

  • Low back of pain intensity measured with Numeric Pain Rating Scale

    It will be measured by the Brazilian version of the Numeric Pain Rating Scale 10 cm. The Numeric Pain Rating Scale goes from 0 to 10, where 0 is "no pain" and 10 is "the worst pain imaginable." Participants will be asked to answer about their pain levels based on the last week. Change in pain score or an improvement of 2 levels or more is accepted as clinically relevant.

    Baseline, 45, 90 and 180 days

Secondary Outcomes (8)

  • Functional capacity measured with Oswestry Disability Index

    Baseline, 45, 90 and 180 days

  • Functional capacity measured with Roland Morris Disability

    Baseline, 45, 90 and 180 days

  • Functional capacity measured with the 6-minute walk test

    Baseline, 45, 90 and 180 days

  • Functional capacity measured with the timed to up and go test

    Baseline, 45, 90 and 180 days

  • Quality of life measured with Short form-36 questionnaire

    Baseline, 45, 90 and 180 days

  • +3 more secondary outcomes
