PROMIS Physical Function - Upper Extremity

PROMIS Physical Function - Upper Extremity is a self-reported person-centered measure that focuses on capability to perform activities that require use of the upper extremity including shoulder, arm, and hand. Examples include writing, using buttons, or opening containers. Responses are scored on a scale of 1 to 5. Individual response scores are summed to get a raw score, which can be converted to a standardized T-score with a mean of 50 and standard deviation of 10.

Time frame: Baseline (pre-fitting)

PROMIS Satisfaction with Social Roles and Activities

PROMIS Satisfaction with Social Roles and Activities is a self-reported person-centered measure that focuses on satisfaction with performing one's usual social roles and activities. Responses are scored on a scale of 1 to 5. Individual response scores are summed to get a raw score, which can be converted to a standardized T-score with a mean of 50 and standard deviation of 10.

Time frame: Baseline (pre-fitting)

Assessment of Capacity for Myoelectric Control (ACMC)

The proctor for the measure chooses an everyday activity, such as setting up a table for snacks or replanting a flower, that is relevant to the study population. As the participants perform the chosen task, a trained rater will assess their capacity for control of their myoelectric prosthesis as represented by 30 items reflecting 6 aspects of quality of myoelectric control. These 6 aspects are "the need for external support," "grip force and opening width," "coordination of both hands, "in different positions and in motion (timing)," "repetitive grip and release," and "the need for visual feedback." Each item is scored on a 4-point scale and converted into linear measures of myoelectric control using Rasch analysis methods on the ACMC website. ACMC is the only measure that has been validated for individuals with upper limb (UL) loss who use myoelectric control and has been shown to demonstrate good test-retest reliability.

The Southampton Hand Assessment Procedure (SHAP)

The SHAP is a time based test of a standardized protocol of 26 timed activities of daily living (ADL) tasks. The SHAP has a set of "common objects" representative of everyday items for the user to pick up. The results of the SHAP is a score which directly compares the abilities of the subject with those of intact able-bodied individuals as well as more refined scores for six prehensile patterns. A SHAP score of 100 is what an intact person is expected to achieve. This test has been validated for normative data.

PROMIS Social Isolation

PROMIS Social Isolation is a self-reported person-centered measure that focuses on perceptions of being avoided, excluded, detached, disconnected from, or unknown by, others. Responses are scored on a scale of 1 to 5. Individual response scores are summed to get a raw score, which can be converted to a standardized T-score with a mean of 50 and standard deviation of 10.

Time frame: Immediately post-fitting

PROMIS Ability to Participate

PROMIS Ability to Participate is a self-reported person-centered measure that focuses on perceived ability to perform one's usual social roles and activities. Responses are scored on a scale of 1 to 5. Individual response scores are summed to get a raw score, which can be converted to a standardized T-score with a mean of 50 and standard deviation of 10.
