background: multiple sclerosis (ms) is the most common disabling neurological disease. hand dysfunction is one of the main complaints of patients with ms. the present study aimed to compare hand dexterity of ms patients with low expanded disability status scale (edss) scores and healthy adults. it also sought to identify the predictors of disability status of patients with ms based on their man...

Objectives: Hand function is critical for daily life and work, especially with the use of electronic devices. This study determined the effect of mirror therapy in individuals with asymmetrical hand function. Method: Forty-two men with asymmetrical hand function were recruited. All participants were randomly divided into two groups: sham control (n = 21) and mirror therapy (n = 21). Both group...

Short-term synchrony was measured for pairs of motor units located within and across muscles activated during a task that mimicked precision grip in the dominant and nondominant hands of human subjects. Surprisingly, synchrony for pairs of motor units residing in separate muscles (flexor pollicis longus, a thumb muscle, and flexor digitorum profundus, an index-finger muscle) was just as large a...

In two experiments, we investigated the impact of spatial attributes on the representation acquired during a serial reaction time task. Two sequences were used, in which structural regularities occurred either in the horizontal or in the vertical locations of successive stimuli. After training with the dominant hand, participants were required to respond with the non-dominant hand to either the...

Observation of others' painful facial expressions has been shown to facilitate behavioral response tendencies and to increase pain perception in the observer. However, in previous studies, expressions were clearly visible to the observer and none of those studies investigated the effect of presence of peripheral stimulation on response tendencies. This study focuses on the effect of sub-optimal...
