Effectiveness of custom-made foot orthoses for treating forefoot pain: a systematic review.

PURPOSE: Pain in and around the metatarsal heads, the metatarsal phalangeal joints and the surrounding soft tissues is called metatarsalgia. Non-operative treatment of metatarsalgia includes foot orthoses. Foot orthoses may be classified as standard or custom-made. A systematic review was carried out to determine whether custom-made foot orthoses are effective for treating forefoot pain.

METHODS: The MEDLINE, CINAHL, The Cochrane Library and PEDro databases were searched for relevant articles reporting patients undergoing treatment for forefoot pain by means of custom-made foot orthoses. Two reviewers independently reviewed all titles and abstracts and extracted the available data. The study eligibility criteria were randomised controlled clinical trials that included participants with forefoot pain treated with custom-made foot orthoses and that reported levels of forefoot pain after the use of orthoses. The data consisted of patient demographics, pathologies related to forefoot pain, type of foot orthoses used, follow-up period and clinical outcomes.

RESULTS: Nine studies were selected which had a total of 487 participants. The pathologies evaluated were rheumatoid arthritis, hallux abductus valgus and isolated and secondary metatarsalgia. The use of custom-made foot orthoses was the intervention that exerted the most significant reduction of the level of pain in the forefoot in most of the studies.

CONCLUSIONS: The use of custom-made foot orthoses improved the level of forefoot pain in rheumatoid arthritis, hallux abductus valgus and secondary metatarsalgia as it increases sole pressures.
