Background: Rates of recurrence, metastases, and mortality for squamous cell carcinoma (SCC) of the upper limb have not been clearly defined.
Objective: We aimed to characterize these tumors and assess the long-term outcomes, comparing with current literature.
Methods And Materials: A retrospective review was performed on 100 consecutive primary cutaneous upper limb SCCs managed surgically by a single hand surgeon between 2012 and 2019. Data collection included patient demographics and tumor factors from the electronic patient records.
Results: One hundred SCCs were identified in 93 patients. Sixty-six percent of patients were male, and the median age was 80 years. Median follow-up was 25 months. Ninety-seven percent of cases were completely excised. The local recurrence rate was 1%, 2% presented with metastases, 4% developed metastases during follow-up, and the mortality related to SCC was 3% with a 33% overall mortality rate.
Conclusions: SCCs of the upper limb behave in a similar manner to those located elsewhere. The local recurrence, metastases, and mortality rates were all low, as such the majority of upper limb SCCs can be managed effectively with a single, low morbidity procedure.Deep margin clearance can be particularly challenging to achieve and an acceptable margin should be considered on an individual basis.

Background: Construct validity and responsiveness of upper limb outcome measures are essential to interpret motor recovery poststroke. Evaluating the associations between clinical upper limb measures and sensor-based arm use (AU) fosters a coherent understanding of motor recovery. Defining sensor-based AU metrics for intentional upper limb movements could be crucial in mitigating bias from walking-related activities.

This study aims to establish an imitation task of multi-finger haptics in the context of regular grasping and regrasping processes during activities of daily living. A video guided the 26 healthy, right-handed volunteers through the three phases of the task: (1) fixation of a hand holding a cuboid, (2) observation of the sensori-motor manipulation, (3) imitation of that motor action. fMRI recorded the task; graph analysis of the acquisitions revealed the associated functional cerebral connectivity patterns.

Purpose: The analgesia nociception index (ANI), also referred to as the high frequency variability index (HFVI), is reported to be an objective measure of nociception. This study investigated changes in ANI after peripheral nerve blocks (PNB) under general anesthesia. Understanding these changes could enhance assessment of PNB efficacy before emergence from general anesthesia.

In this work, we present and evaluate a closed-loop, continuous myoelectric prosthetic hand controller, that can continuously control the position of multiple degrees of freedom of a prosthesis while rendering proprioceptive feedback to the user via a haptic feedback armband. Twenty-eight participants without and ten participants with upper limb difference (ULD) were recruited to holistically evaluate the physical and psychological effects of the controller via isolated control and sensory tasks, dexterity assessments, embodiment and task load questionnaires, and post-study interviews.
