Upper Extremity

The Upper Extremity refers to the anatomical region encompassing the shoulder, arm, forearm, wrist, and hand.
This complex anatomical area is crucial for a wide range of human movements and functions, including reaching, grasping, manipulating objects, and performing fine motor tasks.
Researchers studying the upper extremity may investigate topics such as musculoskeletal structure, biomechanics, sensory and motor control, and the impact of injuries or disorders.
Optimizing upper extremity research protocols is essential for ensuring reproducible and accurate findings that advance our understanding of this important body region.
PubCompare.ai's AI-driven platform can help locate the most proven methodologies from literature, preprints, and patents, enabling researchers to build their studies on a solid foundation and experince the future of research optimization.

Pseudotemporal ordering of AER cells, forelimb or hindlimb was done with Monocle 257 . Briefly, differentially expressed genes across five development stages were identified with the differentialGeneTest function of Monocle 257 . The top 500 genes with the lowest q value were used to construct the pseudotime trajectory using Monocle 257 , with UMI count per cell as a covariate in the tree construction. Each cell was assigned a pseudotime value based on its position along the trajectory. Smoothed gene marker expression change along pseudotime were generated by plot_genes_in_pseudotim function in Monocle 257 . Cells in the trajectory were grouped in the same method as a previous study64 . Briefly, cells were grouped first at similar positions in pseudotime by k-means clustering along the pseudotime axis (k = 10). These clusters were subdivided into groups containing at least 50 and no more than 100 cells. We then aggregated the transcriptome profiles of cells within each group. The gene expression along pseudotime was calculated in the same approach as a previous study64 . Briefly, genes passing significant test (FDR of 5%) across different treatment conditions were selected and a natural spline was used to fit the gene expression along pseudotime, with mean_number_genes included as a covariate. The gene expression for each gene was subtracted by the lowest expression and then divided by the highest expression. Genes with max expression within the early 20% of pseudotime were labeled as repressed genes. Genes with max expression in the last 20% of pseudotime were labeled as activated genes. Other genes were labeled as transient genes. Enriched reactome terms (Reactome_2016) and transcription factors (ChEA_2016) were identified using EnrichR/v1.0 package65 .

All participants in this study were healthy volunteers (students or teachers at the Radboud university medical center), recruited by personal contacts of the authors. They were unaware of the actual purpose of this study and were told that this study investigated their lower extremity coordination. The inclusion criteria were: age between 18 and 65 years old, practice of symmetrical sports (e.g. running, cycling, swimming, rowing) or sports which involve the lower extremities only (e.g. soccer) or people who do not practice any type of sport. Participants that practiced sports in which the upper extremity is predominantly used (e.g. handball, tennis, volleyball) were excluded, because of the introduction of a possible bias as stated by Peters, who mentioned that in athletics, the choice of arm usually influences the choice of the leg [9 (link)]. Other exclusion criteria were surgery to one or both legs in the past three years, a back or lower extremity injury at the moment of testing, the use of medication which influences balance, and the presence of any disease which affects balance or coordination.
Forty-one healthy adults were eligible for inclusion: 21 men aged 35.8 ± 16.5 years old and 20 women aged 36.1 ±15.2 years old. 90% of them were right-handed, which is comparable to the world population [14 (link)]. All participants agreed to take part in this study and gave their written informed consent to their inclusion in this study. This study was approved by the Medical Ethics Committee Arnhem/Nijmegen (registration number 2017–3373).

Young (1 month old) and adult (> 4 months old) mice expressing YFP in a small subset of cortical neurons (YFP-H line29 (link)) were used in all the experiments. Young mice were trained on the single-seed reaching task for up to 16 days and displayed a stereotypical learning curve (Fig. 1b). Naive adult mice and mice that had been previously trained with the single-seed reaching task in adolescence were trained with either the same reaching task or a novel capellini handling task for up to 8 days (see Methods). Apical dendrites of layer V pyramidal neurons, 10–100 μm below the cortical surface, were repeatedly imaged in mice under ketamine–xylazine anaesthesia with two-photon laser scanning microscopy. Spine dynamics in the motor cortex and other regions were followed over various intervals. Imaged regions were initially guided by stereotaxic measurements. In 14 mice, intracortical microstimulation (see Methods) was performed at the end of repetitive imaging to determine the location of acquired images relative to the functional forelimb motor map (Supplementary Fig. 2). In total, 32,079 spines from 209 mice were tracked over 2–4 imaging sessions, with 121 mice imaged twice, 79 mice three times and 9 mice imaged four times. Spine formation and elimination rates in each mouse were determined by comparing images of the same dendrites acquired at two time points; all changes were expressed relative to the total number of spines seen in the initial images. The number of spines analysed and the percentage of spine elimination and formation under various experimental conditions are summarized in Supplementary Table 1. To quantify spine size, calibrated spine head diameters were measured over time30 (link) (Supplementary Notes). All data are presented as mean ± s.d., unless otherwise stated. P-values were calculated using the Student's t-test. A non-parametric Mann–Whitney U-test was used to confirm all conclusions.

Four-limb blood pressure and ABI measurement was performed by trained technicians using a non-invasive vascular profiling system (Omron VP-1000 vascular profiling system, Japan) [3 (link)]. This system ensured accurate and reliable ABI measurement using advanced oscillometric technology. Simultaneous blood pressure measurement at all four limbs was included, using a dual chamber cuff system and a proprietary algorithm. Measurement was performed after a 10-min rest in the supine position with the upper body as flat as possible. The device simultaneously and automatically measured the blood pressures twice, and then we calculated the means to get final blood pressure values. Bilateral ankle and brachial artery pressures, and bilateral ABI were supplied after measurement. ACC/AHA guidelines recommend ABI ≤ 0.90 as the criterion for the diagnosis of lower extremity PAD [8 (link)]. Meanwhile, IABPD ≥ 15 mmHg was considered as the potential abnormalities of upper extremity arteries according to literatures in this study [9 (link), 10 (link)].

Radiographic data consisted of full-length coronal and sagittal radiographs were obtained in free- standing posture with the upper limbs resting on a support, the shoulders at 30° forward flexion, and the elbows slightly flexed [19 (link)]. All of the radiographic parameters were measured with Surgimap Software (version: 2.3.2.1; Spine Software, New York, NY).
All of the radiographic parameters concerned in this current study were shown in the Fig. 1A-B, which included thoracic kyphosis (TK), lumbar lordosis (LL), sagittal vertical axis (SVA), sacral slope (SS), pelvic tilt (PT) and pelvic incidence (PI). All of those radiographic measurements were performed by a dedicated team independent from the operating surgeons.

A Sagittal radiologic parameters: Thoracic Kyphosis (TK) measured from the superior endplate of T4 to the inferior endplate of T12 by Cobb method; Lumbar Lordosis (LL) measured from the superior endplate of L1 to the inferior endplate of S1 by Cobb method. Sagittal vertical axis (SVA) defined as the horizontal offset from the posterosuperior corner of S1 to the plumb line going through the vertebral body of C7. B Pelvic parameters: Sacral slope (SS): the angle between the horizontal line and the sacarl endplate; Pelvic tilt (PT): the angle between the vertical and the line through the midpoint of the sacral endplate to the femoral heads axis; Pelvic Incidence (PI): the angle between the perpendicular to the sacral plate at its midpoint and the line connecting this point to the femoral heads axis

Kyphosis was recorded as positive value ( +), and lordosis as negative value (-). The spinopelvic index (SPI) was calculated by the equation: SPI = SS/PT.

All patients with T2DM were asked whether they had numbness, pain (prickling or stabbing, shooting, burning or aching pain), and paresthesia (abnormal cold or heat sensation, allodynia and hyperalgesia) in the toes, feet, legs or upper-limb. Then, an experienced physician performed the neurologic examination which included vibration, light touch, and achilles tendon reflexes on both sides in the knee standing position (as being either presence or weakening or loss). Vibration perception threshold (VPT) was assessed at the metatarsophalangeal joint dig I using a neurothesiometer (Bio- Thesiometer; Bio-Medical Instrument Co., Newbury, OH, USA). First, the patients were informed how to know the vibration sensation is felt by gradually turning the amplitude from zero to maximum, then the test began again from zero and they were asked to say the moment that they first felt it. Measurements were made on the planter aspect of the big toe bilaterally, three times consecutively for each big toe. The median of three readings is accepted as the VPT value of that measurement (35 (link)). Sensitivity to touch was also tested using a 5.07/10-g Semmes-Weinstein monofilament (SWM) at four points on each foot: three on the plantar and one on the dorsal side. The 10-g SWM was placed perpendicular to the skin and pressure was applied until the filament just buckled with a contact time of 2 s. Inability to perceive the sensation at any one site was considered abnormal (36 (link), 37 (link)). DPN was defined as VPT ≥25 V and/or inability to feel the monofilament (35 (link)), and then participants were divided into DPN group and no DPN group.
Ankle brachial index (ABI) was measured noninvasively by a continuous-wave Doppler ultrasound probe (Vista AVS, Summit Co., USA) with participants in the supine position after at least 5 min of rest. Leg-specific ABI was calculated by dividing the higher SBP in the posterior tibial or dorsalis pedis by the higher of the right or left brachial SBP (33 (link), 38 (link)). Patients were diagnosed as having PAD if an ABI value <0.9 on either limb (33 (link), 38 (link)).
DFU was defined as ulceration of the foot (distally from the ankle and including the ankle) associated with neuropathy and different grades of ischemia and infection (39 (link)).

Prior to clinician assessment and cohort assignment, all eligible and consenting patients were asked to complete the EQ-5D-5L [23 (link)], which assesses problems in 5-dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) that can be used to calculate a utility score, which ranges from 0 (health state equivalent to death) to 1 (perfect health). The EQ-5D-5L also includes a visual analog scale (VAS) that measures current health state, which ranges from 0 to 100 (best possible health). Patients were also asked to complete the SDS [24 (link)], which assesses disruption in 3 social functioning domains (work/school, social life, family life/home responsibilities) and includes a total score (sum of domain scores) which ranges from 0 (no disruption) to 30 (extreme disruption).
For severity of possible TD, clinicians and patients were asked to “rate the severity of visible, uncontrollable movements” for each of 4 body regions (head/face, neck/trunk, upper extremities, and/or lower extremities) using simple descriptors of “none”, “some”, or “a lot”. For impact of possible TD, patients who were aware of their abnormal involuntary movements (Cohort 2A) were asked to rate how much “over the past 4 weeks” did these movements “impact your ability” to perform each of 7 different activities/functions (usual activities, talking, eating, breathing, being productive, self-care, socializing), also using the descriptors of “none”, “some”, or “a lot”. For regression analyses, these descriptors were assigned values of 0, 1, and 2, respectively, with the summary score for severity ranging from 0 (“none” in all 4 regions) to 8 (“a lot” in all 4 regions) and the summary score for impact ranging from 0 (“none” in all 7 activities) to 14 (“a lot” in all 7 activities).
