Summary: In order to validate a new calibration method for a novel instrumented knee brace used for rehabilitation, researchers compared the device to a motion analysis system. Thirteen healthy young adults performed a gait test while wearing the knee brace and their knee kinematics were captured using the brace and a camera system. Results showed excellent reliability and good correlation between the brace and the camera system, indicating that the instrumented knee brace is a valid tool for assessing knee kinematics during walking. The addition of magnetometers did not significantly enhance accuracy.

Summary: Human gait can be measured by observing the joint angle values of the lower limb joints during walking. This article presents a real-time inverse kinematics calculation for a three-link kinematic leg using a musculoskeletal model in OpenSim. The model offers an analytical solution that is both quick and accurate. However, the model-based approach is highly dependent on the morphology of the bipedal robot, leading to limitations in walking trajectories. To overcome these limitations, a learning-based method using the LSTM model is proposed.

Summary: There are conflicting results regarding the changes in spatio-temporal gait parameters during the 6-min walk test (6MWT) as indicators of gait-related motor performance fatigability (PF) in people with Multiple Sclerosis (pwMS). To further analyze if gait-related motor PF can be quantified using instrumented gait analysis during the 6MWT, we investigated: (i) whether gait parameters recorded during the first or second minute were more stable and thus the better baseline to assess motor PF and (ii) if the minimum toe clearance (MTC) together with classical spatio-temporal gait parameters can be used to quantify motor PF in pwMS. It was found that (i) gait parameters were more stable in the second than in the first minute and (ii) gait-related motor PF could not be detected based on spatio-temporal gait parameters, including the MTC. Future studies should investigate gait parameters for the assessment of motor PF in pwMS recorded during more intense and/or longer walking protocols, taking the level of disability into account. Furthermore, using gait parameters recorded in the first minute of the 6MWT as a baseline for the assessment of motor PF should be avoided.

Summary: In this paper, a statistical test for the Multiple Detrended Correlation Coefficient DMCx2 was proposed to evaluate the statistical significance of association between variables. Findings show that acceptance or rejection of the null hypothesis of DMCx2 depends on the series length and time scale evaluated. The study also reveals a behavior pattern in the critical values of DMCx2 as the time scale increases.

Summary: A new multiple cross-correlation coefficient DMC was proposed to quantify the correlation between multivariate and a target variable using de-trended cross-correlation (DCCA) technique. The study found that DMC is approximately chi(2) distributed for overlapping windows and the multiple correlations can be regarded as statistically significant. Furthermore, the influence of cross-correlation among target variable and independent variables on DMC was discussed, and applications in financial system and environment data showed significant effects on international gold spot prices and AQI system.

Summary: This study investigated the immunomodulating properties of two industrially relevant high aspect ratio nanomaterials (nanocellulose and multiwalled carbon nanotubes) on alveolar macrophages. Results showed that these nanomaterials can induce phenotypic changes in alveolar macrophages, with nanocellulose exposure leading to enhanced M1 phenotype and multiwalled carbon nanotubes promoting M2 phenotype. Additionally, multiwalled carbon nanotube exposure resulted in changes in epigenetic patterns and miRNA levels, suggesting the importance of histone methylation and acetylation events in the Th2 response to multiwalled carbon nanotubes.

Summary: In Norway, only 75% of the population can be reached by Helicopter Emergency Medical Services (HEMS) within 30 minutes. Increasing the number of HEMS bases is necessary to reduce response times to 10-15 minutes, but it comes with increased costs. According to the model calculations, 78 or 104 bases are needed to cover 99% or 100% of the Norwegian population within 15 minutes, respectively, with additional personnel and healthcare costs.

Summary: This study explored the feasibility and effects of using a new assistive, electric standing device called Innowalk Pro (IP) for early rehabilitation in patients with severe acquired brain injury. The results showed that IP training was physically demanding but preferred by the patients. Trunk control improved only after withdrawal of IP training. There was a slight reduction in ankle plantar flexor muscle spasticity. Heart rate tended to decrease during IP training, while blood pressure remained stable. Further research is needed to determine whether IP should be a preferred or supplementary assistive device for early mobilization.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
