Article Synopsis
- - Falls are a major public health issue, especially among older adults (≥60 years) in care settings, leading to serious physical and psychological problems; hence, accurate fall risk assessments are vital for prevention and individualized care.
- - This study evaluated the Fall Risk Score (FRS) using real-world data from 617 elderly individuals in Germany to determine its effectiveness in predicting falls over time and to identify critical threshold values.
- - Results indicated a strong correlation between higher FRS scores and an increased number of falls, particularly in participants with slower gait speeds and those using walking aids, emphasizing the FRS's prognostic validity for fall risk assessment.
Article Synopsis
- A study examined the effectiveness of an angle stable locking system (ASLS) compared to conventional intramedullary nailing in treating distal tibial fractures, focusing on recovery metrics like ipsilateral vertical ground reaction forces (vGRF).
- Results showed that patients treated with ASLS demonstrated significantly greater loading and better limb symmetry during the early recovery phase (6 weeks post-surgery) compared to those who received conventional treatment.
- Although ASLS patients showed early improvements, no significant differences in recovery metrics were found at later time points for gait trials or standing assessments.
Younger patients increasingly receive total hip arthroplasty (THA) as therapy for end-stage osteoarthritis. To maintain the long-term success of THA in such patients, avoiding extremely high hip loads, i.e.

This study aimed to characterize ipsilateral loading and return to weight-bearing symmetry (WBS) in patients undergoing total hip arthroplasty (THA) during activities of daily living (ADLs) using instrumented insoles. A prospective study in 25 THA patients was performed, which included controlled pre- and postoperative follow-ups in a single rehabilitation center of an orthopedic department. Ipsilateral loading and WBS of ADLs were measured with insoles in THA patients and in a healthy control group of 25 participants.

While the surgical treatment for acute QTRs is described thoroughly, no common strategy exists for the often frustrating treatment of chronic, reoccurring QTRs. The pro-angiogenic and immunomodulatory properties of placenta-derived adherent mesenchymal stromal-like (PLX-PAD) cells have been described to protect musculoskeletal tissues from inflammation and catabolic cytokine migration, yet little is known about the regenerative potential of PLX-PAD cells in repetitively damaged tendon tissue.

Various methods have been proposed to analyze single bilateral signals but are limited in scope, as they can often use only positive signals or discrete values extracted from time-scale data as input. By defining five symmetry axioms, a framework for benchmarking existing methods was established and a new method was described here for the first time: the weighted universal symmetry index (), which overcomes limitations of other methods.
