April 17, 2026 updated by: Atahan TURHAN, Kirsehir Ahi Evran Universitesi

Validity and Reliability of the The Measure of Activity Performance of the Hand Scale in Patients With Carpal Tunnel Syndrome

The primary aim of the study was to determine the validity and reliability of the "MAP-Hand (Measure of Activity Performance of the Hand)" scale in patients with carpal tunnel syndrome. The secondary aim of the study was to evaluate the hand activity performance in patients with carpal tunnel syndrome.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Patients who apply to the Physical Medicine and Rehabilitation Polyclinic with complaints of hand-wrist pain will be examined by a physical therapist. Patients who are diagnosed with Carpal Tunnel Syndrome through physical examination, meet the inclusion criteria, and agree to participate in the study will be included in the study.

Description

Inclusion Criteria:

  1. Age 18 and above and able to read and write
  2. Diagnosed with mild or moderate unilateral CTS according to electroneuromyography results at least 6 months ago
  3. Motor-sensory symptoms such as numbness and loss of strength in the hand for at least three months
  4. Volunteers with no history of diabetes, no medical treatment or injections, no surgery, and no cervical radiculopathy or polyneuropathy

Exclusion Criteria:

  1. Those with trauma, deformity, fracture, muscle contracture and atrophy in the shoulder, forearm and hand
  2. Those who have received corticosteroid injections into the carpal tunnel area within the last three months and have been included in a physiotherapy program
  3. Those who have cognitive problems

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Hand Activity Performance
Time Frame: 24 weeks
The MAP-Hand (Measure of Activity Performance of the Hand) scale is a scale consisting of 18 items that evaluates the activity performance of the hand. These items are scored between 1 and 4 and the total score ranges from 18 to 72. Lower scores indicate better activity performance. The participants' hand activity performance will be evaluated with the MAP-Hand scale. The reliability and validity of the Turkish form of the MAP-Hand scale was conducted by Bayraktar and colleagues. However, their work has not yet been published. The necessary permissions have been obtained to use the scale.
24 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Grip Strength
Time Frame: 24 weeks
Hand grip strength will be measured with a Camry brand digital dynamometer. Participants will be assessed in an upright position on a chair with their feet on the floor, with their arm next to their body, elbow in 90-degree flexion, forearm in midrotation and wrist in neutral. Participants were verbally encouraged during the test. Measurements were repeated three times and the highest value will be recorded in kilograms.
24 weeks
Hand and Finger Skills
Time Frame: 24 weeks
The participants' hand and finger skills will be tested with the 9-Hole Peg Test (9-DÇT). The 9-DÇT is a test that measures hand and finger skills in daily life. A pegboard with 9 holes, 3.2 cm wide, each hole 1.3 cm deep, will be placed in front of the participants in a way that it will be in the midline of the body. Participants will be asked to randomly place 9 wooden pins on the 9-hole pegboard as quickly as possible and then remove the pins from the pegboard one by one and put them in the box. At the end of 3 trials, the times will be recorded in seconds with a stopwatch and the shortest time will be recorded. A longer time to complete the test indicates inadequacy in hand-finger skills.
24 weeks
Hand Health Status
Time Frame: 24 weeks
Hand health status will be assessed with the "Michigan Hand Outcome Questionnaire (MESA)". MESA consists of 37 questions and is a questionnaire with 6 parameters that evaluate general hand function, daily living activities, pain, work, aesthetics and satisfaction. Each question is evaluated with a 5-point Likert scale and a high score indicates a good status.
24 weeks
Carpal Tunnel Symptom Severity
Time Frame: 24 weeks
The symptom severity and functional status of the participants will be evaluated with the "Boston Carpal Tunnel Syndrome Questionnaire (BCTQ)". BCTQ consists of the symptom severity scale (SSS) and the functional status scale (FSS) that evaluate the patient in two categories. While the SSS consists of 11 items, the FSS consists of 8 items. The average score is calculated by the ratio of the total score obtained to the number of questions. An increase in the average score indicates that the symptom is severe and functional limitation increases.
24 weeks
Pain measurement
Time Frame: 24 weeks
The participants' pain intensity during rest, activity and night will be measured with VAS. According to VAS, pain intensity is evaluated on a 10 cm line between 0 (no pain) and 10 (most severe pain). High scores indicate severe pain. Participants will be asked to indicate the intensity of pain they feel on a 10 cm scale.
