Table 1 Description of study measures

From: Evaluation of EMG pattern recognition for upper limb prosthesis control: a case study in comparison with direct myoelectric control

Test What it measures Content Scoring Interpretation MDC 90
Patient-Specific Functional Scale (PSFS) Difficulty performing activities 5 self-selected activities difficult to do because of the amputation Likert scale 0–10
0 = unable to perform
10 = can perform activity easily
Higher scores indicates less difficulty 6.49
Upper-Extremity Functional Scale (UEFS)- modified Difficulty performing activities Self-reported difficulty performing 22 everyday activities Likert scale 1–5
1 =  very easy
5 =  cannot perform
Lower scores indicates less difficulty 12.07
Clothespin relocation task Dexterity Number of clothespins moved in 1 min Count Higher score indicates better dexterity Unknown
Clothespin relocation with counting backwards Dexterity with cognitive load Number of clothespins moved in 1 min while counting backwards from 100 by 3 s Count Reduction of # clothespins shows the impact of cognitive burden on performance Unknown
Clothespin relocation with semantic fluency Dexterity with cognitive load Number of clothespins moved in 1 min while naming as many fruits and vegetables as possible Count Reduction of # clothespins shows the impact of cognitive burden on performance Unknown
Trinity Amputation and Prosthesis Experience Scales (TAPES) Prosthetic satisfaction 10 items satisfaction with prosthesis Likert scale 1–5
1 = very dissatisfied
5 = very satisfied
Higher scores indicate greater satisfaction 0.79

Activities Measure for Upper-Limb Amputees (AM-ULA) 5 elements of performance: completion: speed, movement quality, skill and independence 18-everyday tasks Likert scale 0–5
0 = unable 5 = excellent
Higher scores indicate better performance 3.7
