BACKGROUND
A stroke often bequeaths surviving patients with impaired neuromusculoskeletal systems subjecting them to increased risk of injury (e.g., due to falls) even during activities of daily living. The risk of injuries to such individuals can be related to alterations in their movement. Using inertial sensors to record the digital biomarkers during turning could reveal the relevant turning alterations.
OBJECTIVES
In this study, movement alterations in stroke survivors (SS) were studied and compared to healthy individuals (HI) in the entire turning task due to its requirement of synergistic application of multiple bodily systems.
METHODS
The motion of 28 participants (14 SS, 14 HI) during turning was captured using a set of four Inertial Measurement Units, placed on their sternum, sacrum, and both shanks. The motion signals were segmented using the temporal and spatial segmentation of the data from the leading and trailing shanks. Several kinematic parameters, including the range of motion and angular velocity of the four body segments, turning time, the number of cycles involved in the turning task, and portion of the stance phase while turning, were extracted for each participant.
RESULTS
The results of temporal processing of the data and comparison between the SS and HI showed that SS had more cycles involved in turning, turn duration, stance phase, range of motion in flexion-extension, and lateral bending for sternum and sacrum (-value < 0.035). However, HI exhibited larger angular velocity in flexion-extension for all four segments. The results of the spatial processing, in agreement with the prior method, showed no difference between the range of motion in flexion-extension of both shanks (-value > 0.08). However, it revealed that the angular velocity of the shanks of leading and trailing legs in the direction of turn was more extensive in the HI (-value < 0.01).
CONCLUSIONS
The changes in upper/lower body segments of SS could be adequately identified and quantified by IMU sensors. The identified kinematic changes in SS, such as the lower flexion-extension angular velocity of the four body segments and larger lateral bending range of motion in sternum and sacrum compared to HI in turning, could be due to the lack of proper core stability and effect of turning on vestibular system of the participants. This research could facilitate the development of a targeted and efficient rehabilitation program focusing on the affected aspects of turning movement for the stroke community.

OBJECTIVES
This case series aimed to determine the feasibility of simultaneous modified Ravitch and David procedures for Marfan syndrome patients with pectus excavatum and annuloaortic ectasia.
METHODS
Between March 2014 and December 2019, 7 consecutive patients underwent simultaneous surgery of modified Ravitch and David procedures for pectus excavatum and annuloaortic ectasia. The completion of cardiac surgery and sternal closure were followed by the modified Ravitch procedure. The bilateral fourth to seventh costal cartilages were resected, the sternal body partially wedge resected and the sternum raised anteriorly with re-suture. An oblique incision was performed on bilateral third costal cartilages, and they were fixed on top of each other, with the medial end superior and the lateral end inferior. The sternum was raised anteriorly, bypassing the fourth to seventh rib ends through the back of the sternum with threads. The feasibility and safety of the procedure were assessed through a retrospective review of the patients' clinical charts.
RESULTS
The total sample had a median age of 28 years and comprised 5 males and 2 females. There was a significant difference in the preoperative and postoperative median Haller index, which were 6.8 and 3.9, respectively. All patients were discharged without serious complications, and there was no significant recurrence of pectus excavatum at 35-92 months postoperatively.
CONCLUSIONS
The results of our case series suggest the feasibility of one-stage surgery for pectus excavatum combined with cardiac surgery using the modified Ravitch procedure. Future efforts should be tailored for more uneventful postoperative clinical courses.

A 33-year-old male was brought to the emergency department after a penetrating arrow injury to the chest. Initial evaluation revealed the arrow was penetrating the sternum, lung, and aortic arch. Because the patient was in a remote area, timely transfer to a specialized center for definitive operative repair was delayed approximately 24 hours. Treatment was focused on minimizing risk of hemorrhage with tight blood pressure control, while tube thoracostomy was deferred to avoid a change in intrathoracic pressure. The left-sided hemothorax was monitored with serial point-of-care ultrasounds. Ultimately he was successfully transferred and underwent successful surgical intervention.

OBJECTIVE
Most patients with atrial fibrillation (AF) report symptoms, while one-third are asymptomatic. We hypothesised that sensory processing, in particular pain, differs in patients with symptomatic and asymptomatic AF.
METHODS
Thirty individuals with permanent AF (15 symptomatic and 15 asymptomatic) completed the Atrial Fibrillation 6 (AF6) and short form 36 Health Survey questionnaires and underwent quantitative pain sensitisation testing using pressure algometry at the sternum (referred pain area) and the tibialis anterior muscle (generalised pain area). The primary objective was to assess differences in pressure pain thresholds (PPT), temporal summation of pain (TSP) and conditioned pain modulation (CPM) in the two groups. The secondary objective was to determine association of demographic and clinical parameters to measures of pain sensitisation.
RESULTS
The symptomatic group had lower PPTs at both tibialis (p=0.004) and sternum (p=0.01), and impaired CPM (p=0.025) and facilitated TSP (p=0.008) at the tibialis but not sternum, compared with the asymptomatic group. The AF6 sum score was negatively correlated to PPT on both tibialis (r=-0.50, p=0.005) and sternum (r=-0.42, p=0.02) and positively correlated to TSP on both tibialis (r=0.57, p=0.001) and sternum (r=0.45, p=0.01), but not to CPM. The physical component summary score was positively correlated to the PPT on both tibialis (r=0.52, p=0.003) and sternum (r=0.40, p=0.03) and negatively to TSP on the tibialis (r=-0.53, p=0.003) but not sternum.
CONCLUSIONS
Patients with symptomatic AF exhibit lower pain tolerance than patients with asymptomatic AF, as well as impaired pain inhibitory control and facilitated summation of pain, indicating that pain sensitisation may be of importance in symptomatic AF.Trial registration numberNCT04649437.

An analysis of literature on the methods of assuming a sitting position and the results of our own research indicated the need to search for biomechanical parameters and existing relationships that would enable a description of sitting body posture. The purpose of this paper is to analyze the relationship between the alignment of the body of sternum and sacrum and the changes in the thoracic and lumbar spine curvatures in children. The study involved 113 subjects aged 9-13 years. A planned simultaneous measurement of the angle parameters of the alignment of the body of sternum and sacrum relative to the body's sagittal axis and the angle parameters of the thoracic and lumbar spine curvatures was performed during a single examination session. The proposed markers of alignment in the corrected sitting body posture are characterized by homogeneous results. A high measurement repeatability was observed when determining the corrected body posture in the study setting. It was noted that changes in the alignment of the body of sternum and sacrum resulted in changes in the thoracic kyphosis and lumbar lordosis angle values, which may be an important component of clinical observations of sitting body posture in children. Implementing the body of sternum alignment angle of about 64° relative to the body's sagittal axis in clinical practice as one of the objectives of postural education may be the target solution for sitting body posture correction in children.

Metastatic hepatocellular carcinoma of the sternum is rare and a few cases of surgical resection have been reported. Anterior chest wall reconstruction after radical resection of the sternum and ribs aims to protect the heart and lung from external damage and herniation and restore physiologic stability of the chest wall during respiration. A variety of reconstruction techniques using various materials have been reported, but so far there are no definitive guidelines for the reconstruction of chest wall defects. Recently, we encountered a rare case of metastatic cancer of the sternum from hepatocellular carcinoma in which radical resection of the sternum and ribs, and anterior chest wall reconstruction with acellular dermal matrix and titanium plates were performed.
