PURPOSE: This paper evaluates user performance in telesurgical tasks with the da Vinci Research Kit (dVRK), comparing unilateral teleoperation, bilateral teleoperation with force sensors and sensorless force estimation. METHODS: A four-channel teleoperation system with disturbance observers and sensorless force estimation with learning-based dynamic compensation was developed. Palpation experiments were conducted with 12 users who tried to locate tumors hidden in tissue phantoms with their fingers or through handheld or teleoperated laparoscopic instruments with visual, force sensor, or sensorless force estimation feedback...

OBJECTIVE: This study aimed to compare the effects of three different kinesio taping (KT) techniques in individuals with myofascial pain syndrome (MPS) who have a trigger point in the trapezius muscle. METHODS: The individuals included in our study were randomly divided into four groups: Group 1: Functional correlation technique, group 2: Fascia correlation technique, group 3: Star taping technique (STT), and group 4: Sham group. The visual analog scale was used to assess pain, cervical joint range of motion (ROM) with a universal goniometer, grip strength with a hand dynamometer, number of active trigger points by palpation, pressure-pain threshold with an algometer, quality of life with the Nottingham Health Profile and functional level with the Neck Disability index were evaluated before and after treatment...

INTRODUCTION: Musculoskeletal injuries are one of the more common injuries in spaceflight. Physical assessment of an injury is essential for diagnosis and treatment. Unfortunately, when musculoskeletal injuries occur in space, the flight surgeon is limited to two-dimensional videoconferencing and, potentially, observations made by the crew medical officer. To address these limitations, we investigated the feasibility of performing physical examinations on a three-dimensional augmented reality projection using a mixed-reality headset, specifically evaluating a standard shoulder examination...

CONTEXT: Myofascial pain syndrome (MPS) is primarily characterized by myofascial trigger points related to fascial adhesions. MPS hinders fascial flexibility and mobility, leading to myofascial limitations, dysfunctional movement, and limitation of motion (LOM). OBJECTIVES: This study determined the association of age, sex, type of work, symptom chronicity, symptom laterality, cervical LOM, altered direction of fascial displacement, and magnitude of superficial fascial displacement during active cervical flexion with the clinical diagnosis of MPS...

This study aimed to improve the effectiveness of SEFS, a fixing solution composed of soap and ethanol. This was achieved by modifying the formulation of SEFS. Additionally, this study aimed to preserve the consistency of organs by perfusing cadavers with mixtures of gelatine-glycerin (gelatine-Gls) and gelatine-polyvinyl alcohol (gelatine-PVA) through vascular access. The modified SEFS embalmed cadavers were divided into two groups: Group I was treated with gelatine-glycerin, and Group II was treated with gelatine-polyvinyl alcohol and each group comprised of two goats and three rabbits...

BACKGROUND: Evidence-based practice for history-taking and physical examination in the evaluation of wrist complaints is limited. PURPOSE: To create a set of recommended diagnostic tests for the clinical assessment of patients with undifferentiated wrist complaints. STUDY DESIGN: An e-Delphi study, following the recommendations on conducting and reporting Delphi studies, was performed. METHODS: In this e-Delphi study, a national multidisciplinary panel of experts was invited to inventory diagnostic tests, based on several case scenarios, for the probability diagnosis in patients (age ≥18 years) with undifferentiated wrist complaints...

Laparoscopic surgery brings substantial benefits to patients. However, it remains challenging for surgeons because of motion constraints and perception limitations. Notably, the perception of interactions with organs is largely compromised. This paper evaluates the effectiveness of a forearm-based skin-stretch haptic feedback system rendering surgical tool tip force. Twenty novice participants had to discern the stiffness of samples to investigate stiffness perception in a simulated laparoscopic task. The experimental protocol involved manipulating samples with three difficulty levels and testing three feedback conditions: no augmentation, visual feedback, and tactile feedback...

BACKGROUND: The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) protocol recommends a 5 s and 1 kg force dynamic palpation around the lateral condylar pole of the temporomandibular joint. However, the accuracy and precision of the generated force are not known. OBJECTIVE: To assess and compare the force profiles generated from dynamic palpation manually and using a palpometer, based on the forces and time recommendations suggested by the DC/TMD protocol...

INTRODUCTION: A 38-year-old African American woman presented with right hip pain and movement restriction. Her medical history included a right hip and knee arthroplasty 10 years prior, history of Slipped Capital Femoral Epiphysis and osteonecrosis of the hip. Preoperative assessment was significant for multiple comorbidities such as obesity (BMI > 38), hypertension, asthma. PATIENT CONCERNS: The patient presented with right hip pain, rated 7/10, and restricted hip flexion, adduction, and abduction...

BACKGROUND: Human movement analysis is usually achieved by tracking markers attached to anatomical landmarks with photogrammetry. Such marker-based systems have disadvantages that have led to the development of markerless procedures, although their accuracy is not usually comparable to that of manual palpation procedures. New motion acquisition systems, such as 3D temporal scanners, provide homologous meshes that can be exploited for this purpose. RESEARCH QUESTION: Can fixed vertices of a homologous mesh be used to identify anatomical landmarks with an accuracy equivalent to that of manual palpation? METHODS: We used 3165 human shape scans from the CAESAR dataset, with labelled locations of anatomical landmarks...

Although there are reports describing segmentectomy by a robotic approach, reports describing robotic subsegmentectomy are rare because this procedure requires more precise anatomical knowledge and exposure of subsegmental pulmonary vessels and bronchi. However, the robotic approach has several advantages, including a high-definition 3-dimensional surgical view and precise motion without tremor, which may allow us to perform the subsegmentectomy more easily. Considering these advantages of the robotic approach, we successfully performed a robotic left S1+2c segmentectomy with a short console time and a good postoperative course...

The study of finger biomechanics requires special tools for accurately recording finger joint data. A marker set to evaluate finger postures during activities of daily living is needed to understand finger biomechanics in order to improve prosthesis design and clinical interventions. The purpose of this study was to evaluate the reliability of a proposed hand marker set (the Warwick marker set) to capture finger kinematics using motion capture. The marker set consisted of the application of two and three marker clusters to the fingers of twelve participants who participated in the tests across two sessions...

Objectives: Hyolaryngeal movement during swallowing is essential to airway protection and bolus clearance. Although palpation is widely used to evaluate hyolaryngeal motion, insufficient accuracy has been reported. The Bando Stretchable Strain Sensor for Swallowing (B4S™) was developed to capture hyolaryngeal elevation and display it as waveforms. This study compared laryngeal movement time detected by the B4S™ with laryngeal movement time measured by videofluoroscopy (VF). Methods: Participants were 20 patients without swallowing difficulty (10 men, 10 women; age 30...

BACKGROUND: The trochanteric bursae are often left unrepaired after total hip arthroplasty (THA) and they retract posteriorly over the muscle belly of the piriformis. Deep gluteal syndrome (DGS) is a multifactorial condition presenting as buttock pain and is attributed to nondiscogenic sciatic nerve irritation or impingement causes. The purpose of this study was to investigate the relationship between bursal repair and incidence of DGS in patients undergoing THA. METHODS: This prospective randomized trial included patients treated with a THA between January and December 2022 for a diagnosis of primary osteoarthritis...

BACKGROUND: The findings of previous studies support the efficacy of cold water immersion (CWI) with carbon dioxide (CO2 ) in enhancing muscle blood flow and maintaining aerobic performance efficiency. We hypothesize that the addition of hydrogen gas (H2 ), known for its antioxidant properties and role in inflammation regulation, to C-CWI can enhance recovery after eccentric exercise. SUBJECTS: and Methods: Thirty-four healthy subjects performed a knee-extensor eccentric exercise...

Axillary web syndrome (AWS) occurs after breast cancer surgery, sentinel lymph node dissection, or sentinel lymph node biopsy. Here, cord-like structures from the axilla to the forearm limit the range of motion of the shoulder joint and cause pain. Although the etiology is unknown, AWS has been attributed to the blockage of normal lymphatic flow. Here, we report a novel case of AWS after venous blood sampling in a patient. A healthy, 31-year-old male patient experienced pain with a limited range of motion of the shoulder joint the day after venous blood was collected from the left upper extremity for a medical checkup, and he presented to an orthopedic outpatient clinic on the day...

Rats' whisking motion and objects' palpation produce tactile signals sensed by mechanoreceptors at the vibrissal follicles. Rats adjust their whisking patterns to target information type, flow, and resolution, adapting to their behavioral needs and the changing environment. This coordination requires control over the activity of the mystacial pad's intrinsic and extrinsic muscles. Studies have relied on muscle recording and stimulation techniques to describe the roles of individual muscles. However, these methods lack the resolution to isolate the mystacial pad's small and compactly arranged muscles...

Adolescent idiopathic scoliosis is a three-dimensional spinal deformity that evolves during adolescence. Combined with static 3D X-ray acquisitions, novel approaches using motion capture allow for the analysis of the patient dynamics. However, as of today, they cannot provide an internal analysis of the spine in motion. In this study, we investigated the use of personalized kinematic avatars, created with observations of the outer (skin) and internal shape (3D spine) to infer the actual anatomic dynamics of the spine when driven by motion capture markers...

OBJECTIVES: To determine whether baseline physical tests have a prognostic value on patient-reported outcomes in Achilles tendinopathy. DESIGN: Prospective cohort study, secondary analysis of data from a randomized trial. METHODS: Patients with chronic midportion Achilles tendinopathy performed a progressive calf muscle exercise program. At baseline and after 2, 6, 12 and 24 weeks, patients completed the Victorian Institute of Sports Assessment-Achilles questionnaire and performed the following physical tests: ankle dorsiflexion range of motion with a bent knee or an extended knee, calf muscle strength, jumping height and pain on palpation (Visual Analogue Scale; 0-100) and after 10 hops (Visual Analogue Scale-10-hops)...

Adductor longus injuries are usually observed at the proximal musculo-tendinous junction, but isolated tendinous ruptures (i.e., avulsion) at the origin on the pubic bone are uncommon. In this article, we report a new case of isolated adductor longus avulsion that occurred in a young athlete and was treated with conservative therapy. An 18 years old semi-professional football player, in the attempt to reach the ball with his right leg, reported acute pain and functional limitation in his left adductor area...
