“…Participants completed six activities of daily living (ADLs) using their intact/dominant and prosthetic/non-dominant hands. Details of each ADL can be found in (Engdahl & Gates, 2021; Engdahl, et al, 2022). Briefly, the ADLs required participants to move objects from a lower to a higher shelf (BASKET, BOX, CAN), place small objects into specific target areas (PILL, PIN), or apply deodorant (DEO).…”

“…Prosthesis users who participated in this study did not have a motorized wrist, so the wrist joint range of motion for these individuals were set to zero degrees. Data from the first and last 10% of the movement were excluded as the shoulder angles were unreliable due to gimbal lock of the shoulder that occurs in neutral positions (near the start and stop of each trial) (Engdahl, et al, 2022; Gates, et al, 2016).…”

“…This lack of motion likely affects the inter-joint coordination strategy used during upper extremity movements. For example, several studies have evaluated kinematic patterns in upper limb prosthesis users during different unilateral (Carey, Jason Highsmith, Maitland, & Dubey, 2008; Engdahl, Lee, & Gates, 2022; Major, Stine, Heckathorne, Fatone, & Gard, 2014) and bilateral (Carey, et al, 2008; Engdahl, et al, 2022) activities of daily living (ADLs). While there were differences across tasks, prosthesis users generally completed ADLs with increased shoulder and trunk range of motion compared to healthy individuals (Carey, et al, 2008; Engdahl, et al, 2022; Major, et al, 2014).…”

While healthy individuals have redundant degrees of freedom of the joints, they coordinate their multi-joint movements such that the redundancy is effectively reduced. Achieving high inter-joint coordination may be difficult for upper limb prosthesis users due to the lack of proprioceptive feedback and limited motion of the terminal device. This study compared inter-joint coordination between prosthesis users and individuals without limb loss during different upper limb activities of daily living (ADLs). Nine unilateral prosthesis users (five males) and nine age- and sex-matched controls without limb loss completed three unilateral and three bilateral ADLs. Principal component analysis was applied to the three-dimensional motion trajectories of the trunk and arms to identify coordinative patterns. For each ADL, we quantified the cumulative variance accounted for (VAF) of the first five principal components (pcs), which was the lowest number of pcs that could achieve 90% VAF in control limb movements across all ADLs (5 ≤ n ≤ 9). The VAF was lower for movements involving a prosthesis compared to those completed by controls across all ADLs (p < 0.001). The pc waveforms were similar between movements involving a prosthesis and movements completed by control participants for pc1 (r > 0.78, p < 0.001). The magnitude of the relationship for pc2 and pc3 differed between ADLs, with the strongest correlation for symmetric bilateral ADLs (0.67 ≤ r ≤ 0.97, p < 0.001). Collectively, this study demonstrates that activities of daily living are less coordinated for prosthesis users compared to individuals without limb loss. Future work should explore how device features, such as the availability of sensory feedback or motorized wrist joints influence multi-joint coordination.

“…Body-powered transhumeral prostheses, like [ 7 ], possess passive degrees of freedom (DOF) and are activated through body movements using mechanisms including buttons on the prosthetic palm, wrist, and elbow. Typically offering two to three DOF at most, these models require coordinated movements between the user’s amputated residual arm and their shoulder or the sound limb shoulder for gesture execution [ 8 ]. An example of this control model is [ 9 ], a TRL-6 prosthesis developed using 3D printing.…”

Globally, 2.5% of upper limb amputations are transhumeral, and both mechanical and electronic prosthetics are being developed for individuals with this condition. Mechanics often require compensatory movements that can lead to awkward gestures. Electronic types are mainly controlled by superficial electromyography (sEMG). However, in proximal amputations, the residual limb is utilized less frequently in daily activities. Muscle shortening increases with time and results in weakened sEMG readings. Therefore, sEMG-controlled models exhibit a low success rate in executing gestures. The LIBRA NeuroLimb prosthesis is introduced to address this problem. It features three active and four passive degrees of freedom (DOF), offers up to 8 h of operation, and employs a hybrid control system that combines sEMG and electroencephalography (EEG) signal classification. The sEMG and EEG classification models achieve up to 99% and 76% accuracy, respectively, enabling precise real-time control. The prosthesis can perform a grip within as little as 0.3 s, exerting up to 21.26 N of pinch force. Training and validation sessions were conducted with two volunteers. Assessed with the “AM-ULA” test, scores of 222 and 144 demonstrated the prosthesis’s potential to improve the user’s ability to perform daily activities. Future work will prioritize enhancing the mechanical strength, increasing active DOF, and refining real-world usability.
