Innovative Modified Passive Functional Shoulder Prosthesis Incorporating a Double-Axis Hinge Shoulder Joint with Servo Motor for Shoulder Disarticulation Patient
Bibliographic record
Abstract
BACKGROUND: Amputation is the removal of a body extremity due to the result of any trauma, medical illness, tumor or surgery. Trauma is the leading cause of amputation in upper limb, accounting for 80% of acquired amputations. The levels of amputation in upper limb are trans-phalangeal, trans-metacarpal, trans-carpal, wrist disarticulation, trans-radial, elbow disarticulation, trans-humeral, shoulder disarticulation, and forequarter amputation. Passive prosthesis is usually prescribed as the involvement of joints is more in amputation and the level of amputation is higher. A passive functional prosthesis can be socially beneficial because it can assist in promoting a psychological acceptance of the amputee’s impaired image. The passive functional prosthesis does provide articulation and need sound limb to achieve desired position. Aim: This study aimed to design and develop modified passive functional shoulder prosthesis incorporating a double-axis hinge shoulder joint with servo motor for enhanced mobility and psychological satisfaction in shoulder disarticulation patient. Method: In this study a patient is taken with the amputation level through the shoulder to which passive functional shoulder prosthesis is prescribed. After this a modified passive functional shoulder prosthesis incorporating a double-axis hinge shoulder joint and servo motor was designed and fabricated for the patients of shoulder disarticulation and pretest data was taken using Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) and then prosthesis is given to the patients and after this post test data was taken and data analysis was done. Result: The modified passive functional shoulder prosthesis incorporating a double-axis hinge shoulder joint and servo motor has improved the function and psychological satisfaction of the patient with shoulder disarticulation the pre-test data was 3.7 and the post-test value comes 8.6. Discussion and conclusion: This study showed improved result in the function and psychological satisfaction of the patient with shoulder disarticulation as the passive functional shoulder prosthesis includes the double axis hinge shoulder joint with servo motor is developed which provide two degree of freedom of movement i.e., the flexion and extension motion in sagittal plane using the servo motor which drive the power from the 12V Li-ion battery. In this study, we evaluated the satisfaction of a patient with modified passive function shoulder prosthesis incorporating a double-axis hinge shoulder joint and servo motor and concluded that it provide the function and psychological satisfaction to the patient with shoulder disarticulation. Key words: Amputation, level of amputation, Shoulder disarticulation, Artificial Limb, Passive Prosthesis.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
