Investigation of Validity and Reliability of the Minnesota Manual Dexterity Test in Parkinson's Disease

January 24, 2025 updated by: Sefa Eldemir, Gazi University

Investigation of Validity and Reliability of the Minnesota Manual Dexterity Test in Patients with Parkinson's Disease

Parkinson's Disease (PD) is a disease that affects upper extremity functional skills with clinical findings such as bradykinesia, rigidity, and hypokinesia, and causes limitations in patients' daily life activities. The impairment of upper extremity functional skills is related to the deficiency in planning both voluntary and complex movements, as well as the deficiency in multiple motor planning. In particular; fine manual dexterity, reaching, and grasping movements are affected, greatly affecting patients' daily activities. Therefore, upper extremity evaluations are an important issue to consider for training upper extremity motor skills in PD. There are minimal assessment tools for evaluating the upper extremity functions of individuals with PD. The Nine-Hole Peg Test and the Jebsen Hand Function Evaluation Test are the most commonly used scales in the evaluation of the upper extremity in PD, and their validity and reliability have been demonstrated. These scales roughly evaluate both extremities separately. However, these scales are not suitable assessment tools for testing activities in which both extremities are frequently used in daily life. Therefore, there is a need for valid and reliable scales that can evaluate upper extremity activities both in isolation and bilaterally. The Minnesota manual dexterity test (MMDT) allows both hands to be evaluated together. It also evaluates hand-eye coordination and gross motor skills in addition to manual dexterity. MMDT is used in individuals with PD, but there is no study in the literature examining the validity and reliability of the scale. Therefore, this study aims to evaluate the reliability and validity of MMDT in individuals with PD.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

At baseline, the MMDT, 9-hole peg test, and Jebsen-Taylor Hand Function Test (JTHFT) will be applied to the MS group. The MMDT will be repeated seven days after the first application in MS. Healthy controls are going to perform only the MMDT.

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.

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
Minnesota Manual Dexterity Test
Time Frame: baseline (on the predetermined assessment day)
The Minnesota Manual Dexterity Test (MMDT) is a performance test designed to evaluate hand functions and hand-eye coordination both unilaterally and bilaterally, higher scores mean a worse outcome
baseline (on the predetermined assessment day)
Minnesota Manual Dexterity Test-second
Time Frame: the second assessment will be conducted after the one week
The Minnesota Manual Dexterity Test (MMDT) is a performance test designed to evaluate hand functions and hand-eye coordination both unilaterally and bilaterally, higher scores mean a worse outcome
the second assessment will be conducted after the one week

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
9-Hole Peg Test
Time Frame: baseline (on the predetermined assessment day)
The 9-Hole Peg Test (9-HPT) evaluates hand dexterity based on performance, higher scores mean a worse outcome

The Jebsen Hand Function Test
Time Frame: baseline (on the predetermined assessment day)
The Jebsen Hand Function Test (JHFT) is one of the objective and standardized tests that assesses fine motor skills and functional hand use by simulating daily living activities, higher scores mean a worse outcome
