continuous passive motion

Inertial measurement units (IMUs) are increasingly being used to assess knee function. The aim of the study was to record patients' activity levels and to detect new parameters for knee function in the early postoperative phase after TKA. Twenty patients (n = 20) were prospectively enrolled. Two sensors were attached to the affected leg. The data were recorded from the first day after TKA until discharge. Algorithms were developed for detecting steps, range of motion, horizontal, sitting and standing postures, as well as physical therapy...

INTRODUCTION: Inactivity and long periods of sitting are common in our society, even though they pose a health risk. Dynamic sitting is recommended to reduce this risk. The purpose of this study was to investigate the effect of continuous passive motion (CPM) conducted by a novel motorized office chair on lumbar lordosis and trunk muscle activation, oxygen uptake and attentional control. STUDY DESIGN: Randomized, single-session, crossover with two periods/conditions...

Intelligent rehabilitation robotics (RR) have been proposed in recent years to aid post-stroke survivors recover their lost limb functions. However, a large proportion of these robotic systems operate in a passive mode that restricts users to predefined trajectories that rarely align with their intended limb movements, precluding full functional recovery. To address this issue, an efficient Transfer Learning based Convolutional Neural Network (TL-CNN) model is proposed to decode post-stroke patients' motion intentions toward realizing dexterously active robotic training during rehabilitation...

Contactless monitoring of heart rate (HR) can improve passive and continuous tracking of cardiovascular activities and overall people's health. Remote photoplethysmography (rPPG) using a camera eliminates the need for a wearable device. rPPG-based HR has shown promising results to be accurate and comparable to conventional methods such as contact PPG. Most experiments use stationary subjects while motion is known to affect the accuracy of remote PPG. In this paper, a novel methodology is introduced to enhance the accuracy and reliability of HR monitoring based on rPPG in the presence of physical activities like Yoga...

BACKGROUND AND OBJECTIVE: Functional mobility, an indicator of the quality of life (QoL), requires fast and flexible changes during motion, which are limited in Parkinson's disease (PD). Recent body-worn sensors have emerged in the last decades as potential solutions to produce digital biomarkers able to quantify mobility outside routine consultations and during real-life scenarios for multiple days at a time. The proposed research aims to study the ability of a wearable motion analysis lab, developed by our team, to produce digital biomarkers of mobility and QoL levels in patients with PD...

OBJECTIVES: ICU patients have an increased risk of joint stiffness because of their critical illness and reduced mobility. There is a paucity of evidence evaluating the efficacy of passive movements (PMs). We investigated whether PMs prevent or reduce joint stiffness in ICU patients. DESIGN: A randomized, controlled, within-participant, assessor-blinded study. SETTING: A 48-bed tertiary care adult ICU. PATIENTS: Intubated patients who were expected to be invasively mechanically ventilated for greater than 48 hours with an ICU length of stay greater than or equal to 5 days, and unable to voluntarily move their limbs through full range of motion (ROM)...

Compartment syndrome is a condition that occurs when there is an increase in pressure within a muscle compartment, leading to a decrease in blood flow to the muscles and nerves within that compartment. If left untreated, this can lead to ischemic contracture, which is a late sequelae of compartment syndrome that occurs when there is sustained ischemic damage to the muscles. Timely diagnosis and treatment are critical in reducing the extent of permanent changes within muscle and nerve tissue. No previously published studies have reported on the treatment of early ischemic contracture resulting from traumatic hematoma in the upper arm...

OBJECTIVE: This study aimed to investigate the effects of a head/neck supporting exoskeleton (HNSE) on the electromyographic fatigue threshold (EMGFT ) of the neck and shoulder muscles during a simulated overhead work task. BACKGROUND: Overhead work is a well-known risk factor for neck and shoulder musculoskeletal disorders due to the excessive strain imposed on the muscles and joints in these regions. METHOD: Fourteen healthy males performed a repetitive overhead nut fastening/unfastening task to exhaustion while wearing and not wearing the HNSE at two neck extension angles (40% and 80% of neck maximum range of motion)...

BACKGROUND: We are unsure if continuous passive motion (CPM) has any role in the nonoperative management of the Primary Stiff Shoulder (frozen shoulder). We hypothesized that there is no difference in pain improvement, range of motion, and function with or without CPM in patients with a primary stiff shoulder. METHOD: We searched the databases for clinical trials comparing CPM versus no-CPM physiotherapy. In the final step, we reviewed five randomized clinical trials...

The development of excellently stretchable, highly mobile, and sustainable power supplies is of great importance for self-power wearable electronics. Transpiration-driven hydrovoltaic power generator (HPG) has been demonstrated to be a promising energy harvesting strategy with the advantages of negative heat and zero-carbon emissions. Herein, this work demonstrates a fiber-based stretchable HPG with the advantages of high output, portability, knittability, and sustainable power generation. Based on the functionalized micro-nano water diffusion channels constructed by the discarded mask straps (MSs) and oxidation-treated carbon nanomaterials, the applied water can continuously produce electricity during the spontaneous flow and diffusion...

BACKGROUND: Inter-segment coordination examines the timing and coupling of multiple body segments and provides a complex understanding of how the neuromuscular system controls the body. Research is required to examine if inter-segment coordination during gait differs between individuals with different knee osteoarthritis (OA) severities and asymptomatic adults. RESEARCH QUESTION: Do inter-segment coordination amplitude and between-trial variability during gait differ between individuals with varying levels of knee OA severity and asymptomatic adults? METHODS: This observational, cross-sectional study included participants with mild/moderate knee OA (n = 38), severe knee OA (n = 24), and asymptomatic adults (n = 51)...

PURPOSE: Evaluating the short- and long-term efficacy of a continuous ten day suprascapular nerve block combined with daily multidisciplinary rehabilitation on shoulder range of motion (ROM), pain, and function in patients with refractory adhesive capsulitis (AC). METHODS: In this retrospective cohort study, patients admitted to a specialized pain clinic for refractory AC for more than 6 months underwent continuous suprascapular nerve blockade for ten days and received 2 hours of physiotherapy and occupational therapy daily...

BACKGROUND: An erroneous motion would elicit the error-related potential (ErrP) when humans monitor the behavior of the external devices. This EEG modality has been largely applied to brain-computer interface in an active or passive manner with discrete visual feedback. However, the effect of variable motion state on ErrP morphology and classification performance raises concerns when the interaction is conducted with continuous visual feedback. NEW METHOD: In the present study, we designed a cursor control experiment...

BACKGROUND: Measuring function with passive in-home sensors has the advantages of real-world, objective, continuous, and unobtrusive measurement. However, previous studies have focused on 1-person homes only, which limits their generalizability. OBJECTIVE: This study aimed to compare the life space activity patterns of participants living alone with those of participants living as a couple and to compare people with mild cognitive impairment (MCI) with cognitively normal participants in both 1- and 2-person homes...

The ultimate goal of these procedures is to improve pain and function, thereby increasing the likelihood of a patient's return to physical activity. Postoperative rehabilitation is a key component for a successful and expedient return to activities. The purpose of this article is to review the current literature regarding common surgical options, rehabilitation protocols, and performance outcomes after operative treatment of articular cartilage defects...

Developing versatile systems that can concurrently achieve energy saving and energy generation is critical to accelerate carbon neutrality. However, challenges on designing highly effective, large scale, and multifunctional photonic film hinder the concurrent combination of passive daytime radiative cooling (PDRC) and utilization of sustainable clean energies. Herein, a versatile scalable photonic film (Ecoflex@h-BN) with washable property and excellent mechanical stability is developed by combining the excellent scattering efficiency of the hexagonal boron nitride (h-BN) nanoplates with the high infrared emissivity and ideal triboelectric negative property of the Ecoflex matrix...

The vestibular cerebellum plays an essential role in maintaining our balance and ensuring perceptual stability during activities of daily living. Here I examine three key regions of the vestibular cerebellum: the floccular lobe, anterior vermis (lobules I-V), and nodulus and ventral uvula (lobules X-IX of the posterior vermis). These cerebellar regions encode vestibular information and combine it with extravestibular signals to create internal models of eye, head, and body movements, as well as their spatial orientation with respect to gravity...

BACKGROUND: Dislocation of the long head of biceps tendon (LHBT) usually involves rotator cuff injury, and isolated dislocation with an intact rotator cuff is rare. Some cases of isolated dislocation have been reported. However, to the best of our knowledge, there has been no report of bilateral dislocation of the LHBT without rotator cuff pathology. CASE SUMMARY: A 23-year-old male presented to our outpatient clinic with left side dominant pain in both shoulders...

BACKGROUND: Total knee replacement (TKR) is a common intervention for people with end-stage symptomatic knee osteoarthritis, resulting in significant improvements in pain, function and quality of life within three to six months. It is, however, acutely associated with pain, local oedema and blood loss. Post-operative management may include cryotherapy. This is the application of low temperatures to the skin surrounding the surgical site, through ice or cooled water, often delivered using specialised devices...
