This observational study aims to examine the relationship between the percentage of limb loss and functional outcomes in individuals with unilateral upper limb amputation. Upper limb amputation can affect posture, balance control, pain levels, daily living activities, hand function, and reaction time. However, limited research has investigated how the amount of limb loss influences these outcomes. Participants between 18 and 65 years of age who use a myoelectric or bionic prosthesis will undergo a series of assessments. These assessments include measurements of postural control using a force platform, posture analysis, evaluation of neck and low back pain using a visual analog scale, daily living activities using a validated questionnaire, hand dexterity using the Box and Block Test, and reaction time using a visual stimulus device. The study does not involve any intervention or treatment. All evaluations will be performed during a single assessment session. The results of this study may help improve rehabilitation planning and provide better understanding of functional changes associated with different levels of limb loss in people with upper limb amputation.

RECRUITINGDaily living activity score
In upper extremity amputees, daily living activities and occupational skills will be assessed using a questionnaire. (0-100 score, Survey on Activities of Daily Living and Occupations of Upper Extremity Amputees)
Time frame: through study completion, an average of 1 year
Postural Sway and Limits of Stability
Postural sway (cm) measured using a force BERTEC platform system.
Time frame: through study completion, an average of 1 year
Postural Sway and Limits of Stability
limits of stability (%) measured using a force BERTEC platform system.
Time frame: through study completion, an average of 1 year
Neck and Back Pain Intensity
Measured using the Visual Analog Scale (VAS) on a 0-10 scale, where 0 indicates no pain and 10 indicates the worst possible pain.
Time frame: through study completion, an average of 1 year
Hand Dexterity
easured using the Box and Block Test (number of blocks successfully transferred from one compartment to another in 60 seconds).
Time frame: through study completion, an average of 1 year
Reaction Time
Measured using the BlazePod system (recorded in milliseconds and the number of correct responses in 30 seconds).
Time frame: through study completion, an average of 1 year
