BackgroundWearable sensors are acquiring more and more influence in diagnostic and rehabilitation field to assess motor abilities of people with neurological or musculoskeletal impairments. The aim of this systematic literature review is to analyze the wearable systems for monitoring shoulder kinematics and their applicability in clinical settings and rehabilitation.MethodsA comprehensive search of PubMed, Medline, Google Scholar and IEEE Xplore was performed and results were included up to July 2019. All studies concerning wearable sensors to assess shoulder kinematics were retrieved.ResultsSeventy-three studies were included because they have fulfilled the inclusion criteria. The results showed that magneto and/or inertial sensors are the most used. Wearable sensors measuring upper limb and/or shoulder kinematics have been proposed to be applied in patients with different pathological conditions such as stroke, multiple sclerosis, osteoarthritis, rotator cuff tear. Sensors placement and method of attachment were broadly heterogeneous among the examined studies.ConclusionsWearable systems are a promising solution to provide quantitative and meaningful clinical information about progress in a rehabilitation pathway and to extrapolate meaningful parameters in the diagnosis of shoulder pathologies. There is a strong need for development of this novel technologies which undeniably serves in shoulder evaluation and therapy.
The purpose of this study was to study the clinical and radiographic changes in the knee after arthroscopic partial meniscectomy (APM) at a long-term follow-up compared with the contralateral knee. We assessed 57 patients (38 males and 19 females) with pre- and postoperative weight-bearing radiography with a follow-up ranging from 5.1 to 12.1 years (mean: 8.1) to analyze prevalence and progression of knee osteoarthritis (OA) after APM. We stratified patients according to body mass index (BMI), type of lesion (degenerative vs. traumatic), and side of meniscectomy (medial, lateral, and medial plus lateral). Patients were evaluated both clinically with Knee Osteoarthritis Outcome Score (KOOS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and radiographically with the Kellgren and Lawrence (K/L) score. Radiographic OA was defined as K/L grade 2 or worse. The prevalence of knee OA was 62.69% in the tibiofemoral compartment. The progression of knee OA was statistically significant, ranging from 17.2% preoperatively to 65.95% postoperatively ( = 0.001) in the medial compartment and from 17.64% preoperatively to 58.82% postoperatively ( = 0.0324) in the lateral compartment. The progression of knee OA in the patellofemoral compartment ranged from 5.26 to 42.10% ( = 0.001). The OA progression regarding BMI was higher into the obese group than the normal-weight group and greater in the degenerative group than the traumatic one. The mean KOOS was 72.01 and the mean WOMAC was 73.84. The Spearman's test showed a statistical significance between clinical and radiographic results. Patients in the obese, overweight, and degenerative tear group had a greater predisposition to OA in the tibiofemoral and patellofemoral compartments after meniscectomy. The level of evidence is III, retrospective study.
It is well established that nocturnal hypoxemia in sleep apnea causes an inversion of the circadian arterial pressure rhythm and triggers nocturnal hypertension. Since sleep apnea is very frequent in dialysis patients, we hypothesized that nocturnal hypoxemia may be a factor that contributes to alter the 24-hour arterial pressure profile in these patients. To test the hypothesis 32 dialysis patients underwent 24-hour blood pressure (BP) monitoring and continuous monitoring of arterial O2 saturation during the night-time. Hemodialysis patients were studied during the non-dialysis day. All patients underwent an echocardiographic study. Thirteen patients had no episode of nocturnal hypoxemia (group I), 7 had at least one episode overnight but less than 2 episodes/hr (group II) and 12 had > or = 2 episodes/hr (group III). The average daytime systolic pressure was similar in the three groups. However, the average nocturnal systolic pressure fell in the first group (-2.5 +/- 4.2%) and rose in the second (+2.0 +/- 3.6%) and in the third (+3.9 +/- 2.2%) group (one way ANOVA, P < 0.005). The relative wall thickness of the left ventricle (RWT) was significantly (P < 0.05) higher in group III than in group I, and in the aggregate (N = 32) there was an inverse relationship between average nocturnal SaO2 and RWT (r = -0.43, P = 0.015). The proportion of patients with concentric remodeling or concentric hypertrophy was higher (P = 0.05) in the group with a more severe degree of nocturnal hypoxemia (group III, 8 of 12) than in the other two groups (group I, 3 of 13; group II, 2 of 7). Nocturnal hypoxemia is associated with the "non-dipping" arterial pressure profile in dialysis patients. Disturbed respiratory control during the night may represent an important cardiovascular risk factor in dialysis patients.
This review reveals low rates of disturbance of growth after ACL reconstruction in skeletally immature patients. Although limited, the available evidence did not support any particular surgical technique when considering disturbance of growth or clinical outcome. Further randomised controlled trials are needed to investigate the efficacy of differing surgical techniques on outcomes in skeletally immature patients. Cite this article: 2017;99-B:1053-60.

Nocturnal hypoxemia is an important correlate of LVH in hemodialysis patients. Such an association is largely independent of arterial pressure. These data further underscore the importance of disturbed respiratory control as a cardiovascular risk factor in dialysis patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
