In recent years, the demand for orthopedic implants has surged due to increased life expectancy, necessitating the need for materials that better mimic the biomechanical properties of human bone. Traditional metal implants, despite their mechanical superiority and biocompatibility, often face challenges such as mismatched elastic modulus and ion release, leading to complications and implant failures. Polyetheretherketone (PEEK), a semi-crystalline polymer with an aromatic backbone, presents a promising alternative due to its adjustable elastic modulus and compatibility with bone tissue.

- The study examined how body positions (supine vs. upright) affect heart and blood pressure responses during exercise in patients with postural orthostatic tachycardia syndrome (POTS) compared to healthy controls.
- Results showed that POTS patients experienced increased heart rates and sympathetic activity while upright, along with decreased baroreflex sensitivity, indicating cardiovascular issues in this position.
- Conversely, during supine exercise, POTS patients had similar cardiovascular responses to healthy controls, suggesting that supine exercise may be a better option for their rehabilitation.*
Influence of Aerobic Exercise on Functional Capacity and Maximal Oxygen Uptake in Patients With Parkinson Disease: A Systematic Review and Meta-analysis.
Arch Phys Med Rehabil
January 2025
Objective: To determine the effects of aerobic training in randomized controlled clinical trials on functional capacity, motor symptoms, and oxygen consumption in individuals with Parkinson disease (PD) through a systematic literature review and meta-analysis.
Data Sources: PUBMED, Web of Science, CINAHL, SciELO, and Medline databases were searched to identify published studies until September 2023.
Study Selection: Randomized controlled clinical trials that evaluated the long-term effect of aerobic exercise in individuals with PD were included.
Background: Executive function (EF) deficits are a significant risk factor for falls among older adults (OAs). However, relationship between EF subdomains (shifting, updating, and inhibition), postural balance (PB), and fall risk in healthy OAs, remains poorly understood.
Objective: This study aimed to investigate the relationship between EF subdomains (shifting, updating, and inhibition) and PB, and to assess their impact on risk of falls in community-dwelling OAs.
