Objectives – Due to the use of increasingly large peripheral nervous system (PNS) palpation tests in clinical assessment, it becomes relevant for the modern physiotherapist, be aware of the reliability and validity of these tests. The aim of this narrative review is to investigate the repeatability and diagnostic accuracy of the peripheral nervous system palpation tests. Materials and methods – Literature search has been carried out between September 2009 and December 2010 in electronic databases PubMed, EMBASE, CINAHL, PEDro and Cochrane Library. Following keywords have been used for research: ‘palpation’ [MeSH]; ‘peripheral nervous system’ [MeSH]; ‘spinal nerves’ [MeSH]. ‘Palpation nerve’, ‘neurodynamics’, ‘clinical examination’, ‘diagnostic testing’, ‘clinical tests’, ‘Tinel sign’ have been also used, because it was suggested by some analyzed articles. Research was conducted with no date restrictions and was limited to articles on adult subjects, in English and Italian languages. Results – PNS palpation tests seem little investigated for its reliability, both for the validity. Most of the articles concern the Tinel‘s test. At the present, the inter-examiner reliability of PNS palpation tests is considered low to moderate. The diagnostic accuracy of the Tinel’s test in carpal tunnel syndrome appear unsatisfactory, particularly with regard to sensitivity. Conclusion – This literature review has provided poor results, both for the little amount of scientific works, both in terms of reliability and validity of these tests. Research in this area should aim to standardize procedure and interpretation of palpation test. Finally, it should be interesting not only to investigate the accuracy of each diagnostic test, but also to study different clusters or combination of tests.
Obiettivi – A causa dell’utilizzo sempre più ampio dei test di palpazione del Sistema Nervoso Periferico (SNP) nella valutazione clinica, diventa importante, per il fisioterapista moderno, essere a conoscenza dell’affidabilità e validità di tali test. Scopo di questa revisione narrativa della letteratura è indagare la ripetibilità e l’accuratezza diagnostica dei test di palpazione del SNP. Materiali e metodi – Tra il settembre 2009 e il dicembre 2010 è stata effettuata una ricerca nelle Banche Dati PubMed, EMBASE, CINAHL, PEDro e Cochrane Library. Le parole chiave utilizzate per la ricerca sono state: ‘palpation’ [MeSH]; ‘peripheral nervous system’ [MeSH]; ‘spinal nerves’ [MeSH]; inoltre sono state utilizzate, perché suggerite da altri articoli, ‘palpation nerve’, ‘neurodynamics’, ‘clinical examination’, ‘diagnostic testing’, ‘clinical tests’, ‘Tinel’s sign’. La ricerca è stata effettuata senza limiti di data e ristretta ai lavori in inglese e in italiano, su soggetti adulti. Risultati – I test di palpazione del SNP appaiono poco indagati sia in merito all’affidabilità, sia riguardo alla validità. La maggior parte dei lavori tratta del segno di Tinel come test di valutazione. Allo stato attuale delle conoscenze, l’affidabilità inter-esaminatore dei test di palpazione del SNP è da considerarsi da scarsa a moderata. L’accuratezza diagnostica del segno di Tinel nella sindrome del tunnel carpale è risultata insoddisfacente, con particolare riguardo alla sensibilità. Conclusioni – La revisione della letteratura ha fornito risultati scarsi, sia per quanto concerne la quantità di materiale scientifico reperito, sia per quanto riguarda affidabilità e validità di questi test. E’ opportuno che gli studi in questo ambito siano effettuati standardizzando le procedure di esecuzione e l’interpretazione dei test. Infine, è opportuno indagare l’accuratezza non solo di ogni singolo test di palpazione, ma anche di diverse combinazioni o cluster di test.
