�Efectividad de las Infiltraciones con colágeno para la fascitis plantar: ensayo clínico aleatorizado�

Abstract

Objectives: Plantar fascitis is a disorder of the plantar fascia, caused by the degeneration of the tissue in this zone. It is one of the most frequent causes of foot pain, affecting the heel. Among numerous treatments used in clinical practice are collagen injections. Due to the lack of scientific evidence regarding the effectiveness of this treatment, the aim of this study is to assess the reduction of pain in patients with plantar fascitis. Patients and methods: A clinical controlled random study in patients has been carried out with bilateral pathology of plantar fascitis. Sixteen patients have taken part in this study. The participants have been divided in two groups: an experimental group (n = 8) received the collagen injection treatment and a control group (n = 8) was treated with the method of dry needling in active myofascial trigger points. Results: The mean pain at the beginning of the study according to the Visual Analog Scale was 7.138 in the right foot and 7.288 in the left foot (p < 0.001) in the entire sample that includes the experimental group “Collagen injection” and control group “Dry needling”. At the end of the study, four months post-treatment, the mean pain was reduced to 0.563 ± SD in the right foot and 0.438 ± SD in the left foot (p<0.001) in both study groups. When performing the Mann-Whitney U test, it is observed that in the 4th week post-treatment there were differences between the treatment group and the control group, with dry needling having a lower range of pain (p < 0.005). Conclusion: It was shown that in both groups (experimental and control groups), the treatments applied were effective, because of the pain caused by plantar fasciitis had been reduced, although some patients still had pain (slight pain) at the end of the study.
