Comparison of Standard Myoelectric Hand and Bionic Hand Use in Individuals With Upper Limb Amputation

Summary

This single-center, prospective, comparative study aims to compare hand function, quality of life, patient satisfaction, task completion time, fatigue, and compensatory elbow, shoulder, and cervical movements in individuals with transradial amputation or wrist disarticulation who use either standard myoelectric or bionic hand prostheses. The primary research questions are:

1. Are there differences in patient satisfaction, quality of life, and hand function between individuals using standard myoelectric and bionic hand prostheses?
2. Do individuals using standard myoelectric and bionic hand prostheses exhibit different kinematics in terms of compensatory shoulder, elbow, and neck movements? Could bionic hand prostheses with their diverse grasping capabilities lead to fewer compensatory movements compared to standard myoelectric hand prostheses?
3. Can fatigue induced by performing specific activities of daily living alter hand function and upper extremity-neck kinematics in individuals using either standard myoelectric or bionic hand prostheses?
4. Can cognitive and physical fatigue following activities of daily living lead to different levels of changes in hand function and upper extremity-neck kinematics in individuals using standard myoelectric and bionic hand prostheses?

Conditions

• Transradial Amputation
• Wrist Disarticulation

Interventions

PROCEDURE

Hand Function Assessment Scales

The Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH), The Box and Block Test (BBT) and Action Research Arm Test (ARAT) will be used as hand function assessment scales.

OTHER

Prosthesis Satisfaction Scale

The Quebec Assistive Technology User Satisfaction Assessment (Q-YTKMD) Questionnaire will be used.

OTHER

Quality of Life Scale

5Q-5D-5L will be used as quality of life scale.

PROCEDURE

Kinematic Analysis

Kinematic analysis of shoulder abduction, elbow flexion, and cervical flexion will be performed during simulated tasks of drinking water from a glass and filling glass of water.

PROCEDURE

Parkour Completion Time

A 10-item daily living activities parkour will be prepared for the participants. During the parkour, the participant will be given the following tasks: opening and closing 10 jar lids, slicing a 20cm cylindrical dough into 10 pieces, simulating drinking soup from a bowl 15 times with a spoon (standard bowl 150 ml, standard tablespoon 10 ml), simulating eating meatballs from a plate with a fork 10 times (approximately 6-10 meatballs per serving), simulating pouring water from a pitcher into a glass 10 times, simulating drinking water from a glass 10 times, simulating brushing teeth for 2 minutes, opening 10 clothespins attached to the edge of a cardboard box and attaching them to the other side, simulating opening and closing a zipper, and putting on shoes and tying shoelaces. The course completion time will be recorded.

PROCEDURE

Fatigue Scale

A pre- and post-parkour will be employed, including a 5-point Likert scale for fatigue assesment, hand function assessment scales and kinematic analysis to participants. The results before and after the parkour will be compared.
