The psychological readiness of athletes and its connection to their functional status in returning to sport after a musculoskeletal injury has been previously studied. The “Psychological Readiness of Injured Athlete to Return to Sport” (PRIA-RS) questionnaire is a widely used tool designed to assess an athlete’s psychological readiness to return to sport. The purpose of the present study is to investigate the validity and reliability of the PRIA-RS questionnaire in Greek football athletes. The questionnaire was administered to 113 football athletes, and its face validity, content validity, concurrent validity, construct validity, test–retest reliability, and internal consistency were assessed. The face and content validity of the PRIA-RS were supported, and an exploratory factor analysis confirmed the instrument’s original two-factor structure. Its concurrent validity was demonstrated by examining correlations between the PRIA-RS and three other measures: the Causes of Re-Injury Worry Questionnaire, the Sport Confidence Questionnaire for Rehabilitated Athletes Returning to Competition, and the Attention Questionnaire for Rehabilitated Athletes Returning to Competition. The PRIA-RS exhibited a good internal consistency (Cronbach’s α = 0.82). The intraclass correlation coefficients (ICCs) for the test–retest reliability of each factor were excellent (ICC = 0.97−0.99). Overall, the PRIA-RS appears to be a valid and reliable tool that rehabilitation professionals can utilize in both clinical practice and research by realizing the athletes’ psychological needs and helping them to return safer with no future musculoskeletal injuries.

The purpose of the present study was to investigate the relationship between re-injury worry, confidence, and attention and athletes’ functional status upon returning to sport after an injury. The sample consisted of 28 amateur-level male football players, aged 18 to 35 years, with a previous lower-limb injury. The athletes followed a physiotherapy rehabilitation program and completed three valid questionnaires examining re-injury worry, sport confidence, and attention returning to sport. The sample also performed three functional tests: (a) single-leg hop for distance, (b) side hop, and (c) the vertical jump. The results showed high correlations between the psychological factors between the functional tests. Physiotherapy duration was positively highly correlated with the time of absence from sport and severity of injury. The severity of the injury was also positively highly correlated with the time of absence from sport. The factors “Functional Attention” and “Distraction Attention” showed a positive and negative correlation with the single-leg hop for distance and the vertical jump, respectively. Athletes with a grade II severity injury showed greater attention compared to grade III severity injury. The increased level of re-injury worry was positively related to “Distraction Attention” and negatively related to the functional ability of the injured limb. The psychological readiness was partially related to the athletes’ functional status. The present study reports the importance of psychological readiness and its relationship with athletes’ functional status of returning to sport following a musculoskeletal sport injury.

Progressive supranuclear palsy is a form of atypical Parkinsonism. People living with Progressive Supranuclear Palsy have various symptoms, such as movement and cognitive disorders, which mainly affect balance and functional ability with an increased risk of falls, dexterity, and dementia. The role of exercise at the early stage of progressive supranuclear palsy remains unclear. The aim of the present study was to examine the effectiveness of an exercise program at the early stage of progressive supranuclear palsy. A patient with a diagnosis of progressive supranuclear palsy within the past year followed a supervised 12-week exercise program (two times per week) by a physiotherapist, with a session lasting about 40 min at a private physiotherapy clinic. Functional status, balance, quality of life, anxiety, and depression were assessed four times with valid instruments and tests. The results from the timed-up-and-go test demonstrated an improvement in performance (MCID value = 3.4). Improvements were observed in the scores of the Parkinson’s Disease Questionnaire-39 (MCID value = 0.6). Finally, an improvement was reported in the score of the anxiety factor of the hospital anxiety and depression scale (MCID value = 1.5). Physiotherapy appears to improve functional capacity, quality of life, and mental health. Further research is needed to confirm these results with a large sample size in combination with other complementary therapies such as mental imagery.
