CONTEXT A dynamic-balance-training (DBT) program supplemented with the Graston instrument-assisted soft-tissue mobilization (GISTM) technique has not been evaluated collectively as a treatment in subjects with chronic ankle instability (CAI). OBJECTIVE To examine the effects of GISTM in conjunction with a DBT program on outcomes associated with CAI, including pain and disability, range of mot...

CONTEXT Poor balance has been associated with increased injury risk among athletes. Neuromuscular-training programs have been advocated as a means of injury prevention, but little is known about the benefits of these programs on balance in high school athletes. OBJECTIVE To determine whether there are balance gains after participation in a neuromuscular-training program in high school athlete...

This study investigated changes in technique and efficiency after high-intensity exercise to exhaustion in elite cross-country skiers. Twelve elite male skiers completed 4 min submaximal exercise before and after a high-intensity incremental test to exhaustion with the G3 skating technique on a 5% inclined roller-ski treadmill. Kinematics and kinetics were monitored by instrumented roller skis,...

The aim of this study was to investigate the effect motor imagery (MI) combined with instructional self-talk on service performance in young novice tennis players. participants were assigned one three groups: control, MI, or MI + self-talk. They performed a pretest (10 serves), participated 5 days intervention sessions, and finally posttest similar pretest. During 20 serves. control group not g...

After 10 years of No Child Left Behind standards-focused education, mathematics scores have improved only marginally for elementary-aged students. Students who developed a solid conceptual mathematics foundation at the elementary level succeeded later in higher-level mathematics courses; thus, educators have sought ways to increase mathematics achievement, especially among elementary school stu...

The article examines issues involved in comparing groups and measuring change with pretest and posttest data. Different pretest-posttest designs are presented in a manner that can help rehabilitation professionals to better understand and determine effects resulting from selected interventions. The reliability of gain scores in pretest-posttest measurement is also discussed in the context of re...

BACKGROUND The parallel-group randomized active-controlled clinical study was conducted to compare the effectiveness of two in-hospital range of motion (ROM) exercise programs following total knee arthroplasty (TKA). Continuous passive motion (CPM) is frequently used to increase ROM and improve postoperative recovery despite little conclusive scientific evidence. In contrast, a new active sling...

high intensity workout provokes damage in muscles with an effect on muscle physiology and function. today, serum levels of creatine and aspartate aminotransferase are widely used as biochemical markers of muscle damage in order to determine the functional status of muscle tissues in both pathological and physiological conditions. this study investigated the effect of a futsal match on some bioc...
