Social and Cognitive Factors in Carpal Tunnel Syndrome

Completed

• Conditions: Carpal Tunnel Syndrome; Carpal Tunnel

• Registration Number: NCT05023603
• Lead Sponsor: Hospital Clínico La Florida

Brief Summary

Carpal tunnel syndrome (CTS) is a compressive peripheral neuropathy, characterized by pain, tingling sensation and paresthesia in the territory of the median nerve, symptoms modulated by psychosocial factors (eg, catastrophic thinking, depression, anxiety).

The objective of the study is to determine those psychological and social components that influence the symptoms and function of patients with CTS.

An observational cross-sectional design will be performed in patients with CTS. The patients will be selected consecutively in two hospitals of the South East Metropolitan Health Service (Santiago, Chile). The study variables will include: Perception of pain using the Visual Analogue Scale (VAS), the extent of symptoms will be evaluated using the Katz diagram; Functional assessment using the abbreviated version of the Disabilities of the Arm, Shoulder and Hand Questionnaire (QuickDASH); Catastrophic thinking as a response to pain using the Pain Catastrophizing Scale (PCS), fear of movement using the Tampa Scale for Kinesiophobia (TSK-11), and emotional state was assessed using the Hospital Anxiety and Depression Scale (HADS). Both are valid and reliable measures used to evaluate the influence of psychosocial factors in patients with CTS. Individual subject factors including duration of symptoms, type of work (desk / non-desk), BMI, age, gender, educational level and economic income will be collected through an interview process.

Primary Outcome Measures

Name	Time	Method
Disability in upper-limb	Baseline (0 weeks)	The Perception of patients of their disability in upper-limb evaluated by The Disabilities of the Arm, Shoulder and Hand (DASH) Spanish version Outcome Measure is a 30-item scored 1-5 (referencia). The assigned values for all completed responses are simply summed and averaged. Scoring: The assigned values for all completed responses are simply summed and averaged and higher values represent a worse Disability in upper-limb
Pain evaluation	Baseline (0 weeks)	Pain will be measured by the Visual Analog Scale for pain (VAS) from 0 to 10, where higher values represent a worse outcome.
Hand diagrams	Baseline (0 weeks)	To define total area marked for pain and numbness. The areas of the hand are marked by the patient and the marked area is quantified in square centimeters.

Secondary Outcome Measures

Name	Time	Method
Lateral pinch strength	Baseline (0 weeks)	Measured using a pinch meter (Preston, Clifton, NJ), following the recommendations of the American Society of Hand Therapists
Pain Interference: Kinesiophobia	Baseline (0 weeks)	Kinesiophobia will be evaluated by Tampa Scale for Kinesiophobia (TSK-11SV) (Spanish adaptation. Gómez-Pérez, López-Martínez y Ruiz-Párraga, 2011). Scoring: Items are summed, with a total score from 11-44 and higher values represent a worse outcome (more pain interference in behavior).
Pain Catastrophizing Scale (PCS)	Baseline (0 weeks)	To assess catastrophic thinking as a response to pain through 13 statements with 4 possible options from 1 "not at all" to 4 "all the time". a higher score indicates a higher catastrophic thinking
Emotional status: Hospital Anxiety and Depression Scale (HAD).	Baseline (0 weeks)	Patient's emotional state will be evaluated by Hospital Anxiety and Depression Scale (HAD), which assess the level of anxiety and depression. Subscales and score range are Anxiety (0-21) and Depression (0-21). Scoring: items of each subscale are summed, indicating: 0-7 normality, 8-10 probably case, 11-21 anxiety or depression clinical case. Higher values represent a worse outcome.
Educational level	Baseline (0 weeks)	At an educational level, it will be categorized according to: complete primary education, complete secondary education and completed university studies.
Socioeconomic status	Baseline (0 weeks)	This indicator is calculated by dividing the effective income of each family by its index of needs. Effective income: monthly average of income received, including work, capital and pensions.
Grip strength	Baseline (0 weeks)	Measured using a Jamar dynamometer (Preston, Clifton, NJ) in the second handle position, following the recommendations of the American Society of Hand Therapists
