Validity of IMPACT-S for Assessing Activities and Participation in patients with Carpal Tunnel Syndrome

Abstract—

Objective of the study:

The study aims to establish whether IMPACT-S is an apt measure for assessing activities and participation in Carpal Tunnel Syndromepatients.

Significance of the study:

Carpal Tunnel Syndrome is one of the commonest entrapment neuropathies leading to marked activity and participation limitations. IMPACT-S is based on the ICF framework for assessing the functional involvement of the subject in terms of activities and participation. The current study focuses on establishing its validity of measuring activities and participation in patients with Carpal Tunnel Syndrome which will help clinicians and researchers use IMPACT-S for CTS patients.

Hypothesis:

Null Hypothesis: There is no validity of IMPACT-S for functional evaluation of Carpal Tunnel Syndrome patients.

Alternate Hypothesis: IMPACT-S is a valid tool for functional evaluation in Carpal Tunnel Syndrome patients.

Operational Definitions:

Validity: The psychometric property of a tool to measure what it is intended to (Singh et al, 2014).

ICF: WHO recommends the International Classification of Functioning (ICF) as a comprehensive measure for assessing and rehabilitating patients (2007).

IMPACT-S: ICF Measure of Participation and Activities – Screener (IMPACT-S) is a self- measure tool for assessing functioning and disability in pateients (Post et.al, 2008).

BCTQ: The Boston Carpal Tunnel Questionnaire is a standardised a scale for assessment of CTS severity and functional ability (Fischer et.al 2014).
