The valid confirmation of a positive change (improvement) in a patient’s health status due to intervention has been at the core of medicine and rehabilitation since their very inception as clinicians always aspired to ensure that treating their patients had led to successful outcomes both in acute and chronic conditions. However what is change: either im-provement or worsening (aggravation), is a complicated issue which involves clinical as well as statistical considerations. Change invariably relates to a difference in some measurable entity and almost always it relates to a time span. The confirmation of clinical change is important both for varying the treatment course (if necessary) and for the termina-tion of treatment when the latter has reached wither its prescribed ob-jective or a plateau. Since in the context of rehabilitation, the outcome measures (OM) are strongly linked to performance, determination of change in the latter is confounded by many factors, collectively known as the error of measurement, which render a decision regarding clini-cally meaningful change, highly involved. This is further complicated by the stability of the observed OM, the so-called reproducibility of the OM, and the accuracy of the measurement instrument. The higher the re-producibility the lower is the error. Moreover, in order to proclaim change, in most cases a positive one, it is necessary for the difference in outcome scores (i.e. the change) to surpass the error of measure-ment, in varying degree of rigor. This paper describes selected methods associated with determination of change and focuses predominantly on the difference between a simple difference in scores (‘simple change’), a significant difference in scores and the so-called clinically meaningful change in scores which is considered today as the bench-mark for confirmation of a real change.

Pulmonary arterial hypertension (PAH) is a rare and devastating dis-ease characterized by progressive increases in pulmonary arterial pressure and pulmonary vascular resistance which eventually leads to right ventricular failure and death. Early thought process was that exer-cise and increased physical activity may be detrimental to PAH patients however many small cohort trials have proven otherwise. In addition to the many pharmaceutical options, exercise and pulmonary rehabilita-tion have also been shown to increase exercise capacity as well as various aspects of psychosomatic health. As pulmonary and exercise rehabilitation become more widely used as an adjuvant therapy patient outcomes improve and physicians should consider this in the therapeu-tic algorithm along with pharmacotherapy.

Epilepsy is a common neurological disorder characterized by seizure and loss of neuronal cells by abnormal rhythmic firing of neurons in the brain. In the present study, we investigated the effect of treadmill exer-cise on gamma-aminobutyric acid (GABA)ergic neuronal loss in relation with neuronal activation using pilocarpine-induced epileptic rats. The rats were divided into four groups: control group, control and treadmill exercise group, pilocarpine-induced epilepsy group, and pilocarpine-in-duced epilepsy and treadmill exercise group. Epilepsy was induced by intraperitoneal injection of 320 mg/kg pilocarpine hydrochloride. The rats in the exercise groups were forced to run on a motorized treadmill for 30 min once a day for 2 weeks. In the present results, neuronal loss in the hippocampal CA1 region was increased after pilocarpine-in-duced seizure. Treadmill exercise inhibited hippocampal neuronal loss in the epileptic rats. Glutamic acid decarboxylase (GAD67) expression in the hippocampal CA1 region was reduced by pilocarpine-induced seizure. Treadmill exercise increased GAD67 expression in the epileptic rats. c-Fos expression in the hippocampal CA1 region was increased in response to epileptic seizure. Treadmill exercise inhibited c-Fos expres-sion in the epileptic rats. Epileptic seizure increased brain-derived neu-rotrophic factor (BDNF) and tyrosine kinase receptor B (TrkB) expres-sions in the hippocampus. Treadmill exercise suppressed BDNF and TrkB expressions in the epileptic rats. In the present study, treadmill ex-ercise prevented GABAergic neuronal loss and inhibited neuronal acti-vation in the hippocampal CA1 region through the down-regulation of BDNF-TrkB signaling pathway.

Diabetes is a metabolic disorder, and it is considered as a major risk factor for Alzheimer’s disease (AD). In the present study, we evaluated whether treadmill exercise ameliorates progression of AD in relation with glycogen synthase kinase-3β (GSK-3β) activity using streptozoto-cin (STZ)-induced diabetic rats. For this study, step-down avoidance task, immunohistochemistry for glycogen synthase kinase-3β (GSK-3β) and tau, and western blot for phosphor-phosphoinositide 3 kinase (p-PI3K)/PI3K and phosphor-Akt (p-Akt)/Akt were performed. Diabetes mellitus was induced by intraperitoneal injection of STZ. The rats in the exercise groups were made to run on the treadmill for 30 min per one day, five times a week, during 12 weeks. The present results showed that short-term and long-term latencies in the step-down avoidance task were decreased by induction of diabetes, and treadmill exercise inhibited these latencies in the diabetic rats. Induction of diabetes sup-pressed the ratio of p-PI3K to PI3K and the ratio of p-Akt to Akt, and treadmill exercise increased these ratios in the diabetic rats. The num-bers of GSK-3β-positive and tau-positive cells in the hippocampal den-tate gyrus was higher in the diabetes-induction group than that in the control group, and treadmill exercise inhibited these numbers in the di-abetic rats. In the present study, treadmill exercise suppressed hyper-phosphorylation of tau in the hippocampus by decreased GSK-3β activ-ity through PI3K/Akt pathway activation in the diabetic rats. Based on the present results, treadmill exercise may helpful to prevent diabe-tes-associated AD occurrence.

After anterior cruciate ligament (ACL) reconstruction, which muscle groups are more affected from frequently developing thigh muscle atro-phy is a matter of debate. We evaluate the effect of thigh circumference difference between patients’ knees who were administered the ACL re-construction with hamstring tendon autograft and intact knees, on torque between the hamstring and quadriceps muscles. Fifty-five pa-tients at least 6 months follow-up period available were included in our study. Power measurements of quadriceps and hamstring muscle groups in patients’ extremities were done by using isokinetic dynamom-eter. The maximum torque values at 60°/sec, 240°/sec in frequency, po-sitions of flexion and extension were determined. In accordance with our findings it is still possible to encounter the thigh atrophy in average 28 months after ACL reconstruction surgery even under physical reha-bilitation programs and appropriate follow-up. It is inevitable for the cli-nician to consider these changes in diagnosis and rehabilitation stages. It can’t be ignored that muscle weakness mechanisms developing in the thigh circumference vary according to the thigh muscle group and knee flexors play an important role in thigh atrophy when determining an appropriate rehabilitation program after reconstruction application.

The purpose of the study was to determine the effect of 8 weeks pre-season training on body composition, physical fitness, anaerobic capacity, and isokinetic strength in collegiate taekwondo athletes. Thir-ty-four collegiate athletes (male: 22, female: 12) participated. Body com-position, bone mineral density, physical fitness, anaerobic capacity, and isokinetic muscle strength were tested. After statistical analysis was performed the results indicated that there were significant decreases in body weight, percent body fat, and fat tissue after 8 weeks of pre-season training. Bone mineral density increased significantly only in males. There were significant improvements in the 50 m shuttle run and 20 m multistage endurance run in both males and females. The sit & reach test and standing long jump were not significantly changed af-ter 8 weeks. Relative peak power and anaerobic capacity were signifi-cantly improved in males. Significant increases in angular velocity were observed for knee extension at both % BW 60°/sec and 180°/sec in both males and females. A significant increase in angular velocity was seen for right knee flexion at % BW 60°/sec for males, but it decreased at % BW 180°/sec for both males and females. In conclusion, this study sug-gests that 8 weeks of pre-season training has a positive effect on body composition, physical fitness, anaerobic capacity, isokinetic muscular strength, and endurance. Nevertheless, an exercise approach with the goal of increasing lean tissue, and improving power in knee flexors and flexibility of athletes, should be included in the training program.

The purpose of the present study is to investigate the relationship be-tween the regions of menstrual pain and of myofascial pain syndrome, which is the main cause of musculoskeletal pain, as well as to examine the changes and relationships among the menstrual pain-related fac-tors, which are pain level, pain area, activity, appetite, mood, and sleep-ing pattern. The subjects were 13 sufferers of musculoskeletal pain and 17 non-sufferers. Pain diary and pain chart systems were used for the measurement of menstrual pain-related factors and musculoskeletal pain. Data were analyzed using repeated ANOVA. The results show that there are significant differences between the two groups in pain level, activity, and mood during menstruation periods (P<0.05). The area of musculoskeletal pain and menstrual pain were found to be the same.

The aim of the present study was to devise a non-damaging high-inten-sity intermittent running protocol. Ten healthy active men completed high-intensity interval running (8×3-min bouts at 90% of maximal oxy-gen uptake interspersed with 3-min recovery) on a motorized treadmill under normal laboratory temperatures. Mean heart rate and rating of perceived exertion significantly increased during the intermittent proto-col (the first bout, 15.3±1.2; the final bout, 18.6±0.9; P<0.001). Blood lactate concentrations were significantly elevated following bout 1 compared with resting values (1.2±0.3 mmol/L vs 5.4±2.4 mmol/L; P=0.03). However, no significant reduction in maximal voluntary con-traction was observed immediately after completing the last exercise bout (623.9±143.6 N) or during the subsequent 7-d period compared to pre-exercise values (P=0.59). Creatine kinase (CK) concentrations were not significantly increased following exercise or during the subse-quent 7-d period (P=0.96). Myoglobin (Mb) content was significantly in-creased following exercise (P=0.01), however, values returned towards pre-exercise concentrations after 24 h. These results indicate that the high-intensity intermittent running protocol induced changes in physio-logical and subjective indices that are consistent with the effects of acute fatigue as opposed to those changes normally associated with exercise-induced muscle damage. This exercise protocol can therefore be used to investigate the influence of high-intensity exercise from physiological responses to molecular adaptation.
