Background/objectives: Dementia is a syndrome which involves cognitive and motor problems such as memory and motor control that impacts the individuals' quality of life. In mental imagery (MI) technique, motor acts are mentally rehearsed without any overt body movements. The aim of this study was to investigate the effectiveness of MI on the quality of life, cognitive, and emotional status of older adults with an early stage of dementia.

: A sport injury is an unfortunate event that can significantly impact the injured athletes' psychology. There have been no studies examining gender differences in the psychological state after a sport-related musculoskeletal injury. Τhe aims of the current study were to (a) investigate the relationship between re-injury worry levels, confidence, and attention in the injured athletes who followed a rehabilitation program in order to return to competition, and (b) compare differences in these psychological factors between male and female athletes.

The purpose of the present cross-sectional study was to examine the relationship between heart rate variability (HRV) and the range of cervical motion, disability, pain intensity, pain catastrophizing, and quality of life in patients with chronic, non-specific neck pain. Thirty-five patients, aged 20-48 years, with chronic non-specific neck pain, completed validated questionnaires regarding neck pain intensity, pain-associated disability, catastrophic thoughts, and quality of life. The range of cervical motion was assessed using a digital goniometer.

Athletes engaging in overhead activities often face injury risks, emphasising the need for reliable assessment tools. This study focused on the translation and psychometric evaluation of the Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow Score into Greek (Gr-KJOC) for assessing upper limb function in Greek-speaking overhead athletes. The Gr-KJOC underwent meticulous translation and adaptation processes, ensuring linguistic equivalence and cultural relevance.

Dementia involves the loss of cognitive abilities and represents a decline from the prior level of function which impairs functional abilities in day-to-day life. No previous experimental research has been done to assess mental imagery (MI) effectiveness in the motor, cognitive and emotional status of individuals with early-stage dementia. One hundred and forty older individuals with early-stage dementia from the Day Care Centre of the Alzheimer Association in Athens will take part in this study.

A lumbar herniation disc appears as a major cause of lumbar pain and sciatica. The purpose of the present systematic review is to examine the effectiveness of such exercise programs on pain, disability, quality of life, strength and the assessed time required to return to work/normal activities after undergoing lumbar discectomy surgery. PubMed, MEDLINE, and Google Scholar were used for the selection of randomized controlled trials (RCTs).

Rehabilitation from sport injury involves not only physical, but also psychological considerations. Re-injury worry, confidence and attention are characteristics that may affect athletes' returning to competition after a sport injury. The study aimed to describe the predictive ability of the re-injury worry, confidence, and attention to the total of re-injuries at the new competitive season.

Background: According to the literature, 20-30% of intubated patients are difficult to wean off mechanical ventilation and have a prolonged intensive care unit (ICU) stay with detrimental effects on muscle strength, functional ability and quality of life. Inspiratory muscle training (IMT) a threshold device has been proposed as an effective exercise for minimising the effects of mechanical ventilation on respiratory muscles of critically ill patients with prolonged weaning. In addition, high-flow nasal cannula (HFNC) oxygen has been proved to provide efficient support for both high- and low-risk patients after extubation, thus preventing re-intubation.

Background: Sport injury is an unfortunate event which can have a major impact on the injured athletes' psychology. Athletes may experience re-injury worry and low levels of attention and confidence getting back to competition following a sport injury. The aim of the study was to examine re-injury worry, confidence and attention of previously injured athletes, before they returned to competition.

: This study's objective was to translate and cross-culturally adapt the Cumberland Ankle Instability Tool (CAIT) into the Greek language and to evaluate its psychometric properties.: CAIT was translated and adapted into Greek according to official cross-cultural adaptation guidelines of self-reported measures. The Greek version of the CAIT (CAIT-GR) was tested for reliability (internal consistency, test-retest reliability), validity (discriminative and convergent validity) and floor-ceiling effects.

The aim of this study was to review and evaluate the psychometric properties of two general musculoskeletal outcome measures focusing on pediatric physical disability, namely, the Pediatric Outcomes Data Collection Instrument (PODCI) and the Activities Scales for Kids (ASK). Although this review reveals the psychometric superiority of ASK to PODCI, further research should confirm the psychometric properties of both the instruments. A number of psychometric issues need to be further addressed.

The present study describes the development and validation of an instrument designed to examine athletes' selective attention returning to competition following a musculoskeletal injury--the attention questionnaire of rehabilitated athletes returning to competition (AQ-RARC). Using a sample of 186 rehabilitated athletes, exploratory factor analysis revealed a 10-item model that examines functional attention and distraction attention. Confirmatory factor analysis further supported the factorial validity of the AQ-RARC with another sample of 184 rehabilitated athletes.

Article Synopsis
  • - The study developed the Causes of Re-Injury Worry Questionnaire (CR-IWQ) to measure factors influencing re-injury anxiety in athletes, addressing a gap in existing tools.
  • - Conducted in three phases, the research validated the CR-IWQ's content relevance, factor structure, concurrent and discriminant validity, and its reliability through various statistical analyses including Exploratory and Confirmatory Factor Analyses.
  • - Findings from 370 athletes revealed a reliable 12-item questionnaire with two main factors: "Re-injury worry due to rehabilitation" and "Re-injury worry due to opponent's ability," confirming its usefulness for clinical and research settings.

A great number of injuries occur in the context of recreational physical activities and competitive athletics. Adherence to sport injury rehabilitation means an injured athlete's compliance (or not) to a sports medicine/injury personnel's instructions of participating in a rehabilitation programme in a clinic, and/or doing rehabilitation exercises at home. It has emerged as an area of interest among physiotherapists and other allied professionals (i.
