Lateral ankle sprains are one of the most frequent athletic injuries in football, causing deficits in balance. Motor Imagery (MI) has been successively included in sports rehabilitation as a complementary therapeutic intervention. The aim of the present study was to explore the effects of MI on static and dynamic balance and on the fear of re-injury in professional football players with Grade II ankle sprains. Fifty-eight participants were randomly allocated into two groups: First—MI group (n = 29) and second—Placebo group (n = 29), and they each received six intervention sessions. The first MI group received MI guidance in addition to the balance training program, while the second Placebo group received only relaxation guidance. One-way ANOVA showed statistically significant results for all variables, both before and 4 weeks after the interventions for both groups. The t-test showed statistically significant differences between the two groups for static balance for the right lower extremity (t = 3.25, S (two-tailed) = 0.002, p < 0.05) and also for heart rate (final value) in all time phases. Further research is needed in order to establish MI interventions in sports trauma recovery using stronger MI treatments in combination with psychophysiological factors associated with sports rehabilitation.

Manual therapy (MT) techniques typically incorporate localised touch on the skin with the application of specific kinetic forces. The contribution of localised touch to the effectiveness of MT techniques has not been evaluated. This study investigated the immediate effects of MT versus localisation training (LT) on pain intensity and range of movement (ROM) for neck pain. In this single-blind randomised controlled trial thirty eligible neck pain volunteers (23 females and 7 males), aged 28.63 ± 12.49 years, were randomly allocated to MT or to a motionless (LT) group. A single three-minute treatment session was delivered to each group's cervico-thoracic area. The LT involved tactile sensory stimulation applied randomly to one out of a nine-block grid. Subjects were asked to identify the number of the square being touched, reflecting a different location on the region of skin. MT involved three-minute anteroposterior (AP) glides and sustained natural apophyseal glides (SNAG) techniques. Pre- and post-intervention pain intensity were assessed using a pressure pain threshold (PPT) algometer and the numeric pain rating scale (NPRS). Neck ROM was recorded with a bubble inclinometer. Improvements in ROM and self-reported pain were recorded in both groups (p < 0.001) without differences in NPRS, ROM or PPT scores between groups (p > 0.05). Tactile sensory training (localisation) was as effective as MT in reducing neck pain, suggesting a component of MT's analgesic effect to be related with the element of localised touch rather than the forces induced during passive movements.

Objectives: The purpose of this multicenter cross-sectional study was to investigate the association between SARC-F, fear of COVID 19, anxiety, depression and physical activity in patients undergoing hemodialysis. Methods: This study was conducted in 3 hemodialysis centers in Greece during the period of the COVID-19 pandemic. Sarcopenia risk was assessed using the Greek version of SARC-F (=4). Demographic and medical history were collected from the patient's medical charts. The participants were also asked to fill the Fear of COVID-19 Scale (FCV-19S), the Hospital Anxiety and Depression Scale (HADS), and the International Physical Activity Questionnaire (IPAQ) questionnaire. Results: A hundred and thirty-two (132) patients on hemodialysis (92 men, 70.75±13.14 years) were enrolled. Sarcopenia risk (utilizing the SARC-F) was found in 41.7% of patients on hemodialysis. The average duration of hemodialysis was 3.94±4.58 years. The mean score values for SARC-F, FCV-19S and HADS were 3.9±2.57, 21.08±5.32, and 15.02±6.69, respectively. The majority of patients were physically inactive. The SARC-F scores were strongly associated with age (r=56; p<0.001), HADS (r=0.55; p<0.001), levels of physical activity (r=0.5; p<0.001), but not with FCV-19S (r=0.27; p<0.001). Conclusion: A statistically significant relationship was recorded between sarcopenia risk and age, anxiety/depression and levels of physical inactivity in patients on hemodialysis. Future studies are necessary in order to evaluate the association of specific characteristics of patients. [ABSTRACT FROM AUTHOR]

*OBJECTIVE: To evaluate the effect of low-load resistance training with blood flow restriction (LLRT-BFR) when compared to LLRT with sham-BFR in patients with lateral elbow tendinopathy (LET). t DESIGN: Randomized controlled trial. * METHODS: Forty-six patients with LET were randomly assigned to a LLRT-BFR or a LLRT with sham-BFR treatment group. All patients received soft tissue massage, supervised exercises with BFR or sham intervention (twice a week for 6 weeks), advice, and a home exercise program. The primary outcome measures were pain intensity, patient-rated tennis elbow evaluation (PRTEE) score, pain-free grip strength, and global rating of change, measured at baseline, 6 weeks, and 12 weeks. Between-group differences were evaluated using mixed-effects models with participant-specific random effects for continuous data. Global rating of change was analyzed using logistic regression. * RESULTS: Statistically significant between-group differences were found in favor of LLRT-BFR compared to LLRT with sham-BFR in pain intensity at 12-week follow-up (-1.54, 95% CI: -2.89 to -0.18; P = .026), pain-free grip strength ratio at 6-week follow-up (0.20, 95% CI: 0.06 to 0.34; P = .005), and PRTEE at 6- and 12-week follow-up (-11.92, 95% CI: -20.26 to -3.59; P = .006, and -15.23, 95% CI: -23.57 to -6.9; P<.001, respectively). At 6- and 12-weeks, patients in the LLRT-BFR group had greater odds of reporting complete recovery or significant improvement (OR = 6.0, OR = 4.09, respectively). * CONCLUSION: Low-load resistance training with blood flow restriction produced significantly better results compared to the LLRT with sham-BFR for all primary outcomes. Considering the clinically significant between-group improvement in function (>11 points in PRTEE) and the better success rates in the LLRT-BFR group, this intervention may improve recovery in LET.

Objectives: The objective of this study was to assess the prevalence rate of probable sarcopenia and to determine the factors associated with it in older people living in Western Greece. Methods: Probable sarcopenia was estimated based on cut-off values for handgrip strength (HGS) as recommended by EWGSOP2. Information about sociodemographic, chronic diseases, fear of falls and lifestyle of the participants were also collected. HGS was assessed using a SAEHAN dynamometer. Calf circumference was assessed with inelastic tape. A logistic regression analysis was performed in order to determine associated risk factors. Results: The sample comprised 402 participants (292 women;110 men), with a mean age of 71.51±7.63 years. Overall, 25.4% of the elderly participants were diagnosed with probable sarcopenia (men:36.4%; women:21.2%). The findings of this study demonstrated that probable sarcopenia was positively associated with age (OR=0.14, 95% CI=0.008 to 0.200), gender (OR=-0.6, 95% CI=-0.700 to -0.530), Body mass Index (OR=0.01, 95% CI=-0.030 to -0.005), Skeletal muscle mass index (OR=0.05, 95% CI=0.030 to 0.080), calf circumference (OR=0.02, 95% CI=0.007 to 0.040), and comorbidities (OR=0.04, 95% CI=0.030 to 0.080). Conclusion: There was a 25.4% prevalence of probable sarcopenia in Greek elderly. The results highlight the importance of the detection of HGS and probable sarcopenia in older people in order to develop effective strategies of prevention and intervention of sarcopenia.

Objectives: 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. Methods: 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. Additionally, a cut-off value discriminating between stable and unstable ankles across healthy participants and participants with ankle complaints was calculated. A convenience sample of 123 Greek individuals was recruited, 43 of which had a history of at least one ankle sprain. All participants completed the final version of the CAIT-GR twice within 7–10 days. Participants with a history of ankle sprain also completed the Greek version of the Lower Extremity Functional Scale (LEFS) and the Visual Analogue Scale (VAS). Results: CAIT–GR mean scores were 26.9 ± 3.16 for participants without a history of ankle sprain and 20.6 ± 4.62 for the instability group. The cut-off value was at 24.5 points of the total CAIT score (range 0–30). CAIT-GR had a moderate correlation with VAS (0.54) and a high correlation with LEFS (0.735). Results indicated good discriminative validity, high internal consistency (Cronbach's alpha of 0.97) and excellent test–retest reliability (ICC2,1 = 0.97, 95%CI = 0.97–0.98). Neither a floor nor a ceiling effect was observed. Conclusions: The CAIT-GR questionnaire was found to be a reliable and valid measure for chronic ankle instability. It is therefore, available for use in future clinical research and practice. [ABSTRACT FROM AUTHOR]

Background: Chronic obstructive pulmonary disease (COPD) is associated with a progressive loss of muscle mass and function and a systemic inflammatory process that can cause sarcopenia. Objective: The objective of this study is to estimate the prevalence rate of sarcopenia in COPD patients and to determine the factors associated with sarcopenic patients living in Western Greece. Methods: European Working Group on Sarcopenia in Older People criteria were applied to 69 outpatients with stable COPD. Body composition, exercise capacity, functional performance, physical activity, and health status were also assessed. COPD disease severity (COPD stage) was evaluated with the Global Initiative for chronic obstructive lung disease. The study protocol was approved by the Ethical Committee of the Technological Educational Institute of Western Greece. Results: The sample comprised 69 patients (59 women and 10 men), with a mean age of 71.33 ± 7.48 years. The prevalence of sarcopenia was 24.6% (n = 17). A high percentage (82.6%; n = 57) of the 69 Greek participants did not perform any regular exercise. The findings of this study demonstrated that sarcopenia was positively associated with COPD, age, body mass index, skeletal muscle mass, hand grip strength, and 4 m test. Conclusions: In conclusion, there is a 24.6% prevalence of sarcopenia in patients with COPD. Further research with larger samples would be indicated to clarify the precise association of specific characteristics of patients with sarcopenia and COPD. [ABSTRACT FROM AUTHOR]

Purpose: To translate and validate into the Greek language and setting the Sarcopenia Quality of Life (SarQoL®) questionnaire. Methods: A convenience sample of 176 Greek elderly people (136 females, 40 males; aged 71.19 ± 7.95 years) was recruited, 50 of which (36 females, 14 males) were diagnosed sarcopenic. Questionnaire was back-translated and culturally adapted into Greek according to international guidelines. To validate the Greek SarQoL®, we assessed its validity (discriminative power, construct validity), reliability (internal consistency, test–retest reliability) and floor/ceiling effects. Participants were divided into sarcopenic and non-sarcopenic. Sarcopenic subjects apart from the Greek SarQoL (SarQoLGR) filled out the Greek versions of two generic questionnaires; Short Form-36 and EuroQoL 5-dimension. Results: The Greek SarQoL questionnaire was translated without major difficulties. SarQoLGR mean scores were 52.12 ± 11.04 (range: 24.74–71.81) for sarcopenic subjects and 68.23 ± 14.1 (range: 24.83–94.81) for non-sarcopenic ones. Results indicated good discriminative power across sarcopenic and non-sarcopenic subjects (p = 0.01), high internal consistency (Cronbach's alpha of 0.96) and excellent test–retest reliability (ICC = 0.96, 95% CI = 0.95–0.97). Neither a floor nor a ceiling effect was observed. Conclusions: The Greek SarQoL was found to be a reliable and valid measure of quality of life for sarcopenic patients. It is therefore, available for use in future clinical research and practice. The Greek version of the SarQoL® questionnaire is a valid and reliable outcome measure for assessing patients with sarcopenia. The Greek SarQoL is recommended to be use in clinical settings and research. The Greek SarQoL® questionnaire is available online . [ABSTRACT FROM AUTHOR]

Objective: To assess the effects of early self-managed focal sensorimotor training compared to functional exercise training after total knee replacement on functional mobility and sensorimotor function. Design: A single-blind controlled clinical trial. Setting: University Hospital of Rion, Greece. Subjects: A total of 52 participants following total knee replacement. Outcome measures: The primary outcome was the Timed Up and Go Test and the secondary outcomes were balance, joint position error, the Knee Outcome Survey Activities of Daily Living Scale, and pain. Patients were assessed on three separate occasions (presurgery, 8 weeks post surgery, and 14 weeks post surgery). Intervention: Participants were randomized to either focal sensorimotor exercise training (experimental group) or functional exercise training (control group). Both groups received a 12-week home-based programme prescribed for 3–5 sessions/week (35–45 minutes). Results: Consistently greater improvements (F2,98 = 4.3 to 24.8; P < 0.05) in group mean scores favour the experimental group compared to the control group: Timed Up and Go (7.8 ± 2.9 seconds vs. 4.6 ± 2.6 seconds); balance (2.1 ± 0.9° vs. 0.7 ± 1.2°); joint position error (13.8 ± 7.3° vs. 6.2 ± 9.1°); Knee Outcome Survey Activities of Daily Living Scale (44.2 ± 11.3 vs. 26.1 ± 11.4); and pain (5.9 ± 1.3 cm vs. 4.6 ± 1.1 cm). Patterns of improvement for the experimental group over time were represented by a relative effect size range of 1.3–6.5. Conclusions: Overall, the magnitude of improvements in functional mobility and sensorimotor function endorses using focal sensorimotor training as an effective mode of rehabilitation following knee replacement.

Background and Purpose In Greece, as in many countries, there is a scarcity of evidence in the type of physiotherapy services offered for the rehabilitation of total knee replacement (TKR). Despite the number of TKRs annually performed in Greece (over 10,000), there are no available clinical guidelines as to the content of best physiotherapy practice. The aim of this nationwide survey undertaken by physiotherapists treating TKR patients post-operatively was to record standard practice and services available in Greece. Methods Design: cross-country survey Ten per cent of all registered physiotherapists working in public/private sectors were recruited. The developed survey comprised of questions regarding therapists' profile, protocols implemented at different stages of rehabilitation and the aims and modalities used. Results A 58.7% response rate was achieved, where 36% (47/132) of respondents were treating patients in the inpatient phase and 64% (85/132) after hospital discharge. Patients in Greece are discharged with a home-based exercise program (56.7%) and, to a lesser extent, are referred to rehabilitation centres (13.3%). Strengthening, range of movement and functionality seemed to be the primary goals especially in the inpatient phase, whereas in the outpatient phase, apart from the larger differences identified, functionality and balance training were more frequently reported. Conclusions No significant variations in practice were found during inpatient rehabilitation, whilst there seemed to be diversity across outpatient physiotherapy programs. The current survey suggests that patient's general health and psychological and behavioural issues are the criteria by which physiotherapists select the volume of implemented exercise and progression. However, no specific guidelines were followed. Copyright © 2016 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Background: Ankle sprain is an extremely common injury in soccer players. Despite extensive research, the intrinsic cause of this injury under noncontact conditions remains unclear. Purpose: To identify intrinsic risk factors for noncontact ankle sprains in professional soccer players. Study Design: Cohort study; Level of evidence, 2 Methods: One hundred professional soccer players were assessed in the preseason for potential risk factors of noncontact ankle sprains. The assessment included (A) ankle joint asymmetries (right-left) in isokinetic muscle strength, flexibility, proprioception, and stability; (B) somatometric asymmetries; (C) previous injuries; and (D) lateral dominance traits. Noncontact ankle sprains were prospectively recorded and diagnosed for a full competition period (10 months). Results: Seventeen of the players sustained at least 1 noncontact ankle sprain. Logistic regression revealed that players with (A) eccentric isokinetic ankle flexion strength asymmetries (odds ratio [OR] = 8.88; 95% confidence interval [CI], 1.95-40.36, P = .005), (B) increased body mass index (OR = 8.16; 95% CI, 1.42-46.63, P = .018), and (C) increased body weight (OR = 5.72; 95% CI, 1.37-23.95, P = .017 ) each had a significantly higher risk of a noncontact ankle sprain. A trend for younger players (OR = 0.28; 95% CI, 0.061-1.24, P = .092) and for players with ankle laxity asymmetries (OR = 3.38; 95% CI, 0.82-14.00, P = .093) to be at greater risk for ankle sprain was also apparent to the limit of statistical significance (.05\P\.10). Conclusion: Functional strength asymmetries of the ankle flexors and increased body mass index and body weight raise the propensity for ankle sprains in professional soccer players. Age and asymmetries in ankle laxity are potential factors worth revisiting, as there was an indication for younger players and players with ankle instability to be at higher risk for ankle injury. Proper preseason evaluation may improve prevention strategies for this type of injury in soccer. [ABSTRACT FROM AUTHOR]

Physical therapy is a well-respected health profession in Greece. The first school providing 2 years' training for Physical Therapy Assistants started in 1958. Over the years, physical therapy studies have been incorporated into the public non-university tertiary education with seven semesters of teaching and clinics plus 6 months of placement in state hospitals or rehabilitation centres. There are four physical therapy departments in Greece belonging to Technological Educational Institutions which are academically equivalent to universities. Their standards are regulated according to the Declaration of Bologna as are other higher education institutes in Europe. There are about 5000 registered Greek physical therapists; their license is valid throughout the country and they work in public institutions or in the private sector either as employees or in their own private clinics. They choose and execute the acts of physiotherapy after a written diagnosis or opinion of a doctor. The official body is the Greek Society of Physiotherapists which promotes professional claims and shares the educational and scientific up-grading of physical therapists with the Greek Scientific Society of Physical Therapy.

Objective: To translate and validate into Greek, the SARC-F questionnaire, a screening tool for sarcopenia., Methods: Questionnaire was back-translated and culturally adapted into Greek according to guidelines proposed by the World Health Organization. A convenience sample of 197 Greek elderly people (71.6±7.8 years, 68.5% women) was recruited, 64 of which were classified as persons at risk of sarcopenia according to the SARC-F. Internal consistency, test-retest and inter-rater reliability were evaluated. Validity (sensitivity, specificity, predictive positive value and predictive negative value) was assessed against the definition from the European Working Group of Sarcopenia in Older People (EWGSOP2), which is considered gold standard. Receiver-operating characteristic analysis was also performed to calculate the area under the curve., Results: SARC-F demonstrated high internal consistency (Cronbach's alpha of 0.93) and excellent inter-rater and test-retest reliability, with intraclass correlation coefficient (ICC) of 0.91 (95% CI 0.79-0.96), and 0.93 (95% CI 0.91-0.95), respectively. According to the definition of sarcopenia from the EWGSOP2, 53 (26.85) participants were identified as probable sarcopenic and 23 (11.6%) as sarcopenic. Sensitivity of the tool for sarcopenia was 34.4 and specificity was 93.2. Positive predictive values were 26.4 and negative predictive values were 66.6%., Conclusion: Τhe SARC-F was successfully adapted into Greek language. The Greek SARC-F revealed low sensitivity but high specificity with EWGSOP2 sarcopenia definitions, indicating that it can detect with precision the absence of sarcopenia., Competing Interests: The authors have no conflict of interest.

Background: There is accumulating evidence for the advantages of rehabilitation involving sensori-motor training (SMT) following total knee replacement (TKR). However, the best way in which to deliver SMT remains elusive because of potential interference effects amongst concurrent exercise stimuli for optimal neuromuscular and morphological adaptations. The aim of this study was to use additional outcomes (i.e. muscle strength, activation and size) from a published parent study to compare the effects of early-initiated home-based rehabilitative SMT with functional exercise training (usual care) in patients undergoing TKR., Methods: A controlled clinical trial was conducted at the Orthopedic University Hospital of Rion, Greece involving allocation concealment to patients. Fifty-two patients electing to undergo TKR were randomised to either early-initiated SMT [experimental] or functional exercise training [control] in a home-based environment. Groups were prescribed equivalent duration of exercise during 12-weeks, 3-5 sessions of ~ 40 min per week of home-based programmes. Muscle strength and activation (peak force [PF]; peak amplitude [Peak Amp.] and root mean square of integrated electromyography [RMS iEMG]), muscular size (including rectus femoris muscle cross-sectional area [CSA RF ]), and knee ROM were assessed on three separate occasions (pre-surgery [0 weeks]; 8 weeks post-surgery; 14 weeks post-surgery)., Results: Patients undertaking SMT rehabilitation showed significantly greater improvements over the 14 weeks compared to control in outcomes including quadriceps PF (25.1 ± 18.5 N vs 12.4 ± 20.8 N); iPeak Amp. (188 ± 109.5% vs 25 ± 105.8%); CSA RF (252.0 ± 101.0 mm 2 vs 156.7 ± 76.2 mm 2 ), respectively (p < 0.005); Knee ROM did not offer clinically relevant changes (p: ns) between groups over time. At 14 weeks post-surgery, the SMT group's and control group's performances differed by relative effect sizes (Cohen's d) ranging between 0.64 and 1.06., Conclusion: A prescribed equivalent time spent in SMT compared to usual practice, delivered within a home-based environment, elicited superior restoration of muscle strength, activation and size in patients following TKR., Trial Registration: ISRCTN12101643 , December 2017 (retrospective registration).

The torque-time curve patterns of concentric isokinetic knee extension in anterior cruciate ligament (ACL) deficient patients usually present mid-range irregularities associated with the level of anterior tibial translation. The purpose of this study was to compare the smoothness in isokinetic torque production between the ACL deficient and the healthy knee. Thirty ACL deficient soccer players performed bilaterally five trials of maximum concentric knee extension-flexion at 60 degrees /s on a Biodex dynamometer. The three middle trials (a total of six curves) were retained and submitted to further data processing. Maximum frequency values contained within the 90%, 95% and 99% level of the signal power were calculated for each extension and flexion curve. The frequency content of the ACL deficient side proved to be statistically higher compared to the intact side at all levels of the power spectrum. The percentage differences in the frequency content were 18.8%, 10.6% and 40.0% for knee extension, and 49.5%, 24.5% and 16.3% for knee flexion, for the respective power levels. This indicated higher oscillations and, therefore, more unstable mechanical output of the injured knee. An overall biological interpretation of the present results is based on the notion that disturbed motion is generally connected to poor level of joint functionality.
