objectives to explore the effect of a selective 10-week corrective exercise with an emphasis on gait training activities (gta) on the number of falls (nofs), fear of falling, functional balance, timed up and go (tug) test among pd patients. background posture instability and unsteady gait disorders in parkinson’s disease (pd) usually contribute to fall-related fractures. fall-related trauma in ...

Background: Balance disorder is one of the most-studied fields in low-back pain patients (LBP). However, there isinsufficient information regarding the effect of LBP subgrouping on postural control. The purpose of the present studywas to compare postural control between subgroups of chronic nonspecific LBP and healthy subjects during lifting.Methods: A total of 35 men with chronic LBP (19 activ...

BACKGROUND In the past, plyometric training (PT) has been predominantly performed on stable surfaces. The purpose of this pilot study was to examine effects of a 7-week lower body PT on stable vs. unstable surfaces. This type of exercise condition may be denoted as metastable equilibrium. METHODS Thirty-three physically active male sport science students (age: 24.1 ± 3.8 years) were randomly ...
