Brief Summary

The purpose of this study is to evaluate the motor imagery ability in transradial amputees using myoelectric prosthesis, compare it with the control group and investigate its effect on functionality and proprioception.

Conditions

Amputation of Upper Limb Below Elbow; Prosthesis User

Keywords

Imagery; Amputee; Prosthetic; Functional; Myoelectric

Outcome Measures

Primary Outcomes (1)

• Movement Imagination Questionnaire-3

  In order to determine the imagery ability of all individuals included in the amputee and control groups, the "Movement Imagery Questionnaire-3" developed and validated and validated in Turkish will be used (internal consistency coefficient: 0.87). With the 12 items in this questionnaire, internal visual imagery, external visual imagery and kinesthetic imagery abilities will be assessed through four actions each. The actions will be actively performed by the individuals at the beginning. Then, they were asked to perform these actions as mental tasks. These mental tasks were scored using a seven-point Likert scale (1: very difficult to see, feel; 7: very easy to see, feel). In the calculation of the score, the average score of the four relevant actions will be taken for each of the three sub-dimensions.

Study Arms (2)

Transradial Amputees Using Myoelectric Prosthesis

The Standardized Mini Mental Test (SMMT) will be used to assess the cognitive status of individuals, the Beck Depression Inventory (BDI) to assess depression symptoms, the Movement Imagery Questionnaire-3 to assess motor imagery ability, the Mental Chronometry Test (MKT) to measure motor imagery time, the mobile application called "Orientate" to assess hand mental rotation task performance, the Box and Block Test to assess gross motor dexterity and functionality, the Jebsen Taylor Hand Function Test (JTEFT) to assess fine and gross motor functions of the hand, the Disabilities of the Arm Shoulder and Hand (DASH) for upper extremity functional assessment, the Modified Functional Reach Test (MFUT) to measure the dynamic balance of the trunk and the Joint Position Sense measurement to assess proprioceptive sense.

Other: No intervention

Control Healthy Group

The Standardized Mini Mental Test (SMMT) will be used to assess the cognitive status of individuals, the Beck Depression Inventory (BDI) to assess depression symptoms, the Movement Imagery Questionnaire-3 to assess motor imagery ability, the Mental Chronometry Test (MKT) to measure motor imagery time, the mobile application called "Orientate" to assess hand mental rotation task performance, the Box and Block Test to assess gross motor dexterity and functionality, the Jebsen Taylor Hand Function Test (JTEFT) to assess fine and gross motor functions of the hand, the Disabilities of the Arm Shoulder and Hand (DASH) for upper extremity functional assessment, the Modified Functional Reach Test (MFUT) to measure the dynamic balance of the trunk and the Joint Position Sense measurement to assess proprioceptive sense.
