Balance disorders and falls are frequently observed in subjects with multiple sclerosis (MS). Along with motor impairment, sensory disorders and integration deficits of sensory inputs lead to inadequate motor responses. The assessment of these sensory disorders in an every day tasks, such as upright stance, increases our knowledge of postural control in(More)
OBJECTIVE To evaluate the effects of balance retraining in a sample of people with multiple sclerosis. DESIGN Randomized controlled trial. SETTING Rehabilitation unit. SUBJECTS A consecutive sample of 44 subjects was randomized into two experimental groups and one control group. The inclusion criteria were: ability to stand independently more than 30(More)
OBJECTIVE To establish the test-retest and interrater reliability as well as the concurrent construct validity of the Dynamic Gait Index (DGI) as a measure for dynamic balance in people with chronic stroke. DESIGN Cohort study. SETTING Day hospital and ambulatory care at a rehabilitation center. PARTICIPANTS A consecutive sample of 25 participants, at(More)
PURPOSE Balance rehabilitation is an important component of the retraining program in people with multiple sclerosis (MS). Measuring balance is fundamental for an accurate assessment and therapy selection. The aim of this study was to compare interrater and test-retest reliability of the Berg Balance Scale, the Dynamic Gait Index, the Dizziness Handicap(More)
Thirty-nine adult individuals with stroke in the stable phase were asked to walk at their preferred speed and then as fast as possible. A set of gait indexes were computed, including spatial temporal parameters, ankle and hip mechanical work, and timing of ankle push-off onset, for comparison with normal velocity-dependent profiles. Algorithms were used to(More)
Approximately 60% of stroke survivors experience hand dysfunction limiting execution of daily activities. Several methods have been proposed to objectively quantify fingers' joints range of motion (ROM), while few studies exist about multi-finger coordination during hand movements. The present work analysed this aspect, by providing a complete(More)
This paper reports the main findings from a prevalence study of adolescent gambling and problem gambling among Icelandic adolescents. The final sample consisted of 3,511 pupils aged 13 to 15 in 25 primary schools in Reykjavík. The results indicated that 93% of adolescents had gambled some time in their life and 70% at least once in the preceding year.(More)
PURPOSE The purpose of the study was to compute Virtual Time to Contact (VTC) from stabilometric assessment to study balance impairments in people with multiple sclerosis (PwMS). To this purpose we assessed the ability of VTC to discriminate between balance skills of PwMS and healthy subjects (HS), among sensory conditions and between fallers and non(More)
PURPOSE In accordance with the Task Oriented Approach, clinicians need assessment procedures providing information on the execution of multiple tasks. Instrumented task assessment can add information regarding sensory-motor strategies, difficult to assess purely by clinical observation. It has been shown that People with Multiple Sclerosis (PwMS) have(More)
OBJECTIVE The aim of this study was to assess the effect of Kinesio Taping on body stability in subjects with MS. STUDY DESIGN Non controlled intervention study in a Rehabilitation Unit. INTERVENTION A consecutive convenience sample of 15 individuals with multiple sclerosis was assessed. Kinesio Tex Tape was applied directly to the skin of both calves(More)
