The Reliability and Construct Validity of the Neck Disability Index and Patient Specific Functional Scale in Patients With Cervical Radiculopathy

Abstract: Our results suggest that the PSFS exhibits superior reliability, construct validity, and responsiveness in this cohort of patients with cervical radiculopathy compared with the NDI. Further research is needed to examine the ability of these measures to accurately reflect changes in individuals, as well as large samples of patients.

“…The average of these three scores was used for data analysis of 'daily pain'. 48 The NPRS has demonstrated acceptable levels of testretest reliability (ICC50.59 47 to 0.63 46 ) and a 2.2 point change in the NPRS has been reported to be clinically meaningful. 47 Upper Limb Neurodynamic Test (ULNT ROM and ULNT Pain) The ULNT was performed as described by Wainner et al 5 The initial amount of scapular depression was standardized with the use of a pressure sensor (Stabiliser, Chattanooga, Australia) in a manner described by Edgar et al 32 The pressure cuff was folded in 3 to fit the superior region of the patient's shoulder.…”

“…43,44 Neck Disability Index (NDI) The NDI is a self-report measure containing 10 items that assesses a patient's disability due to neck pain. 45 Test-retest reliability for the NDI in patients with cervical radiculopathy has been reported to be fair (ICC50.55) 39 to moderate (ICC50.68), 46 and the minimal clinically important change has been reported to be range from 7.0 points or 14% 46 to 8.5 points or 17%. 47 …”
