AI Article Synopsis

  • The study explored the effectiveness of the Jebsen-Taylor Hand Function Test (JTT) in assessing hand function post-surgery, comparing it to the Michigan Hand Outcomes Questionnaire (MHQ).
  • The results indicated a poor correlation between JTT scores and MHQ scores, suggesting that the JTT may not accurately reflect patient-reported outcomes or levels of disability.
  • Ultimately, the research concluded that the JTT should not be utilized as a reliable measure for assessing hand function or clinical changes after surgery.

Article Abstract

Purpose: The aim of this study was to demonstrate the validity and responsiveness of the Jebsen-Taylor Hand Function Test (JTT) in measuring hand function in patients undergoing hand surgery, compared with the Michigan Hand Outcomes Questionnaire (MHQ).

Methods: A prospective cohort of patients with rheumatoid arthritis (n = 37), osteoarthritis (n= 10), carpal tunnel syndrome (n = 18), and distal radius fracture (n = 46) were evaluated preoperatively and at 9 to 12 months of follow-up. We administered the JTT and MHQ. We performed correlation and receiver operating characteristic analyses to evaluate the validity of the JTT as a measure of disability. Effect size and standardized response means were calculated to determine responsiveness.

Results: Correlation studies revealed poor correlation of the JTT with MHQ total scores and subsets that relate to hand function. Patients with high MHQ scores generally perform well on the JTT; however, patients with good JTT scores do not necessarily have high MHQ scores. Receiver operating characteristic curves for each condition showed that the change in JTT total score had poor ability to discriminate between high and low MHQ score subjects, with an area under the curve result of 0.52 to 0.66 for each condition. Effect size and standardized response means for all states showed greater responsiveness with the MHQ for each condition compared with the JTT.

Conclusions: We found poor correlation between the change in JTT and absolute JTT scores after surgery compared with change in MHQ and absolute MHQ scores. In addition, the JTT had poor discriminant validity based on the MHQ as a reference. This study showed that the time to complete activities does not correlate well with patient-reported outcomes. We conclude that the JTT should not be used as a measure of disability or clinical change after surgical intervention.

Soft capacitive sensors are widely utilized in wearable devices, flexible electronics, and soft robotics due to their high sensitivity. However, they may suffer delamination and/or debonding due to their low interfacial toughness. In addition, they usually exhibit a small measurement range resulting from their limited stiffness variation range.

Background And Purpose: To develop a new test to assess the motor coordination of the upper limbs, and to investigate the test-retest and inter-rater reliability, construct validity, standard error of measurement (SEM), minimum detectable change (MDC), and the reference values.

Methods: The Upper Extremity Motor Coordination Test (UEMOCOT)was applied for 20 s, with the individual touching two targets (one right and one left) as quickly as possible, first with the hand (manual task) and then with the index finger (finger task). To test-retest reliability, the UEMOCOT was administered two times.

In the face of advancements in microrobotics, intelligent control and precision medicine, artificial muscle actuation systems must meet demands for precise control, high stability, environmental adaptability and high integration miniaturization. Carbon materials, being lightweight, strong and highly conductive and flexible, show great potential for artificial muscles. Inspired by the butterfly's proboscis, we have developed a carbon-based artificial muscle, hydrogen-substituted graphdiyne muscle (HsGDY-M), fabricated efficiently using an emerging hydrogen-substituted graphdiyne (HsGDY) film with an asymmetrical surface structure.

The neuropeptide oxytocin (OXT) and its receptor (OXTR) have been shown to play an important role in glucose metabolism, and pancreatic islets express this ligand and receptor. In the current study, OXTR expression was identified in α-, β-, and δ-cells of the pancreatic islet by RNA hybridization, and OXT protein expression was observed only in β-cells. In order to examine the contribution of islet OXT/OXTR in glycemic control and islet β-cell heath, we developed a β-cell specific OXTR knock-out (β-KO) mouse.
