This app is designed for people who wish to participate in scientific studies related to the cognitive symptoms associated with Fibromyalgia. Fibromyalgia is a complex disease of unknown cause that can present a wide range of symptoms of varying intensities. In addition to chronic pain and fatigue, Fibromyalgia is characterized by a series of neurological and cognitive symptoms. People living with Fibromyalgia may experience neurological problems, which often occur in the form of headaches, tinnitus, dizziness, sleep problems (such as insomnia), or mood disorders (such as anxiety or depression). People living with Fibromyalgia can be affected by various alterations in their cognitive abilities. This app is used to investigate the following aspects related to this disorder: Focused Attention, Recognition, Short-Term Memory, Short-Term Visual Memory, Denomination, Working Memory, Cognitive Flexibility, Planning, and Processing Speed. INVESTIGATIVE TOOL FOR EXPERTS IN NEUROSCIENCE This application is designed to promote scientific research by providing digital tools which help in the cognitive evaluation and treatment of people living with cognitive symptoms related to Fibromyalgia. Fibromyalgia Cognitive Research is an instrument for the scientific community and universities around the world. To participate in research focusing on evaluation and cognitive stimulation related to Fibromyalgia, download the APP and experience the most advanced digital tools that are being developed by researchers around the world. This app is for research purposes only and does not claim to diagnose or treat Fibromyalgia. Further research is required to draw conclusions.

SIFIS

La fibromialgia è una malattia complessa e debilitante caratterizzata da dolore muscolare cronico diffuso ed astenia, associato a rigidità e ad una vasta gamma di disturbi funzionali (cefalea, colon irritabile, cistite interstiziale, turbe del sonno, disturbi cognitivi, sindrome delle gambe senza riposo, ecc.) che possono gravemente compromettere la qualità della vita del paziente. La prevalenza della fibromialgia è stimata in Italia nell’ordine del 2,2% della popolazione generale adulta (1). Colpisce soprattutto le donne, con un rapporto femmine-maschio di 8:2, e la prevalenza della malattia aumenta con l’avanzare dell’età. Nel corso degli anni sono stati sviluppati numerosi criteri diagnostici e classificativi che includono oltre al dolore cronico diffuso, molti sintomi somatici e cognitivi (2,3). Tali criteri sono tuttora di difficile applicazione nella pratica clinica ambulatoriale e sono scarsamente impiegati come strumenti di screening. Il SIFIS – SImple FIbromyalgia Screening questionnaire, si propone come un valido strumento di screening, di semplice utilizzo nella pratica ambulatoriale e di sicura utilita’ negli studi epidemiologici. Le diverse tappe dello sviluppo del SIFIS hanno comportato: (1) l’identificazione di una popolazione specifica di pazienti, (2) lo sviluppo e la selezione di una serie numerosa di item, (3) la semplificazione del numero degli item, e (4) lo studio finale di validazione dello strumento, condotto su 230 pazienti con fibromialgia. Sensibilità, specificità, valori predittivi positivi, rapporti di verosimiglianza (LR+ e LR-) e probabilità post-test dei 6 item identificati, sono stati determinati allo scopo di studiare la migliore combinazione possibile. Il valore di LR+ dei 6 item è risultato compreso fra 3.37 e 5.00. La verifica della probabilità post-test è stata indagata mediante la formula di Bayes (o teorema di Bayes o teorema della probabilità delle cause) e l’algoritmo matematico è stato implementato nell’applicazione.

Verdict
The clearest difference is in-app purchases: SIFIS at none against Fibromyalgia's 7. SIFIS also leads on update cadence (weekly vs every 4 months) and iOS requirement (11.0 vs 16.0). On price, ads and device support there is nothing between them.
