The effect of dextrose prolotherapy versus placebo/other non-surgical treatments on pain in chronic plantar fasciitis: a systematic review and meta-analysis of clinical trials.

BACKGROUND: Prolotherapy is the injection of a small volume of sclerosing or irritant solutions into an injured tissue. We aimed to investigate the effect of dextrose prolotherapy (DPT) versus placebo/other non-surgical treatments on pain in chronic plantar fasciitis. METHODS: We searched seven electronic databases (PubMed/MEDLINE, Web of Science, EMBASE, Scopus, ProQuest, CENTRAL, PEDro) from inception to December 31, 2021 with no language restriction for publications comparing the effect of DPT with placebo/other non-surgical treatments in patients with chronic plantar fasciitis. Our primary outcome was pain and the secondary outcomes were foot function and plantar fascia thickness. The risk of bias was assessed using the Cochrane Collaboration's tool. RESULTS: Overall, eight studies with a total of 449 patients were included in the meta-analysis. All the included studies reported short-term pain. A large effect size (dppc2 = -0.97, 95% confidence interval [CI] -1.84 to -0.10) was observed favoring the use of DPT to reduce pain in patients with chronic plantar fasciitis in the short-term. The results for foot function improvement (dppc2 = -1.28, 95% CI -2.49 to -0.07) and plantar fascia thickness reduction (dppc2 = -1.02, 95% CI -1.99 to -0.05) in the short-term were also in favor of DPT. CONCLUSIONS: Since almost all the included studies had high risk of bias and multiple trials lacked long-term follow-ups, further high-quality research is required to determine the long-term effects of DPT vs placebo/other non-surgical interventions.

Validity and reliability of the Persian version of self-administered foot evaluation questionnaire (SAFE-Q) in people with foot orthopedic problems.

INTRODUCTION: Foot problems are one of the main causes of seeing a doctor. According to the World Health Organization's definition of health, the healthcare system must consider patients' quality of life as an important entity. In this regard, many tools have been developed to evaluate patients' opinions about their health status. The purpose of the present study is to evaluate the validity and reliability of the Persian version of the Foot Self-Assessment Questionnaire (SAFE-Q) in patients with foot orthopedic problems. METHOD: 215 people aged 17-60 years with orthopedic foot problems were included in this cross-sectional study. The Spearman correlation coefficient of SAFE-Q questionnaires versus Foot Function Index (FFI) questionnaire was evaluated for the convergent validity. Forty-three people randomly completed SAFE-Q again one week later. Intraclass correlation coefficient (ICC) and Cronbach's alpha was calculated to evaluate the test-retest reliability and internal consistency of the SAFE-Q, respectively. RESULTS: A strong relationship was found between the SAFE-Q total score and other scales with FFI questionnaire (r = 0.52 to 0.87). ICC test-retest reliability and Cronbach's alpha were 0.981 and 0.98 for SAFE-Q, respectively. CONCLUSION: The results indicate that the Persian version of the SAFE-Q questionnaire has acceptable validity and reliability and can be used to assess the health status and quality of life of Persian speakers with orthopedic foot problems.

The incidence and characteristics of chronic pain and fatigue after 12 months later admitting with COVID-19; The Post- COVID 19 syndrome.

INTRODUCTION: This study aimed to evaluate chronic pain and fatigue in patients 12 months after hospitalization for Covid-19. METHODS: We studied the COVID-19 patients discharged from Hospital, March 10 and April 20, 2020. RESULTS: A total of 157 patients were included in this study. Forty-three patients (27.4%) complained of chronic fatigue and muscle weakness in the last six months. The visual analog fatigue scale (VAFS) score of 3.84 ± 1.48 was obtained. Forty patients (25.5%) were suspected of Chronic Fatigue Syndrome (CFS).Twenty-four patients (15.3%) had severe chronic pain or exacerbation of previous chronic pain, most of which were reported in the lower back (70.8%) and lower extremities (66.7%). Pain intensity had a mean score of 2.33 ± 0.87 and was mainly described as "muscle cramps," "persistent dull pain," and "boring and numbing." In women, chronic pain and fatigue, extended hospital stays, ICU admission, and depressed mood were common than in men.For these pain and fatigue, 37% used nonsteroidal anti-inflammatory drugs, and 16.3% used antidepressants. Only one person had applied for physiotherapy, and none of the patients had received psychotherapy. CONCLUSION: Fatigue and chronic pain in patients recovering from COVID-19 are common complications, even after 12 months of illness.
