1. Classification of muscle stretch receptor afferents in humans
Abstract : The response patterns of human stretch receptors in the finger extensor muscles of the forearm were studied using the microneurography technique. Single-unit recordings were obtained from one-hundred and twenty-four afferents. READ MORE

2. Identification of single motor units in ultrafast ultrasound image sequences of voluntary skeletal muscle contractions
Abstract : The central nervous system controls human force production by successive recruitment of motor units in the skeletal muscles and changing their neural firing rate. The motor unit comprises a motoneuron, its innervated muscle fibers, and its axons. READ MORE

3. Voluntary activation of skeletal muscle in young and old women and men
Abstract : The evaluation of skeletal muscle strength is an important part of the physiotherapist’s clinical examination in order to plan and execute appropriate interventions. This requires the objective assessment of muscle strength and the determination of the underlying factors of muscle weakness. READ MORE

4. Lumbar muscle fatigue and recovery : evaluation of electromyography in patients with long-term low-back pain and in healthy subjects
Abstract : Background: Lumbar muscle function is considered to be an important component of longterm low- back pain. The change in the median frequency of the power spectrum of the electromyographic (EMG) signal is commonly used to estimate muscle fatigue. READ MORE

5. An Investigation of the Influence of Knee Flexion Angle on the Activity of the Triceps Surae Muscles during the Heel-Raise Test
Abstract : Background: The heel-raise test (HRT) is used in clinical practice and research to assess the triceps suare (TS) muscles. The test involves repetitive unilateral heel-raises in upright stance. The test is administered with the knee straight for gastrocnemius medialis (GM) and lateralis (GL), and with the knee bent for soleus (SOL). READ MORE
