The purpose of this study was to describe, interpret and compare the EMG activation patterns of ankle muscles - tibialis anterior (TA), peroneus longus (PL) and gastrocnemius lateralis (GL) - in volleyball players with and without ankle functional instability (FI) during landing after the blocking movement. Twenty-one players with FI (IG) and 19 controls(More)
OBJECTIVES To study the activation patterns of tibialis anterior, peroneus longus and gastrocnemius lateralis muscles during a lateral shuffle maneuver in volleyball players with functional instability of the ankle joint. DESIGN Observational case-control study. SETTING Research laboratory. PARTICIPANTS Sixteen players with functional instability and(More)
BACKGROUND This study evaluated the structure and amount of variability of surface electromyography (sEMG) patterns and ankle force data during low-level isometric contractions in diabetic subjects with different degrees of neuropathy. METHODS We assessed 10 control subjects and 38 diabetic patients, classified as absent, mild, moderate, or severe(More)
We investigated the muscle fiber conduction velocity (MFCV) during gait phases of the lower limb muscles in individuals with various degrees of diabetic peripheral neuropathy (DPN). Forty-five patients were classified into severity degrees of DPN by a fuzzy model. The stages were absent (n=11), mild (n=14), moderate (n=11) and severe (n=9), with 10 matched(More)
CONTEXT AND OBJECTIVE In basketball, the most common injuries are ankle sprains. For this reason, players frequently use external ankle devices or taping as prophylactic and rehabilitation measures. The purpose of this study was to evaluate ground reaction force (GRF) responses in basketball players while performing typical cutting maneuvers with and(More)
INTRODUCTION This study evaluates the complexity of force and surface electromyography (sEMG) during knee extension and flexion at low-level isometric contractions in individuals with different degrees of diabetic peripheral neuropathy (DPN). METHODS Ten control and 38 diabetic participants performed isometric contractions at 10%, 20%, and 30% of maximal(More)
TO THE EDITOR: We read with interest the Physiology in Medicine review by Allen et al. (1) on the role of the neuromuscular consequences of diabetic neuropathy (DPN). Three main points in the review deserve attention and should be further discussed. First, DPN-related motor unit (MU) loss is suggested to be linked with the duration and severity of DPN.(More)
AIMS/HYPOTHESIS Early diagnosis of diabetic polyneuropathy (DPN) is critical for a good prognosis. We aimed to identify different groups of patients, based on the various common clinical signs and symptoms of DPN, that represent a progressive worsening of the disease before the onset of plantar ulceration or amputation. We also sought to identify the most(More)
