• Modulations of corticospinal excitability following rapid ankle dorsiflexion in skill- and endurance-trained athletes 

  Hu, Nijia; Avela, Janne; Kidgell, Dawson J.; Piirainen, Jarmo M.; Walker, Simon (Springer, 2022)

  Purpose Long-term sports training, such as skill and endurance training, leads to specific neuroplasticity. However, it remains unclear if muscle stretch-induced proprioceptive feedback influences corticospinal ...

• Revising the stretch reflex threshold method to measure stretch hyperreflexia in cerebral palsy 

  Valadão, Pedro; Bar-On, Lynn; Cenni, Francesco; Piitulainen, Harri; Avela, Janne; Finni, Taija (Frontiers Media SA, 2022)

  Hyper-resistance is an increased resistance to passive muscle stretch, a common feature in neurological disorders. Stretch hyperreflexia, an exaggerated stretch reflex response, is the neural velocity-dependent component ...

• Modulation of H-reflex and V-wave responses during dynamic balance perturbations 

  Nevanperä, Samuli; Hu, Nijia; Walker, Simon; Avela, Janne; Piirainen, Jarmo M. (Springer, 2023)

  Motoneuron excitability is possible to measure using H-reflex and V-wave responses. However, it is not known how the motor control is organized, how the H-reflex and V-wave responses modulate and how repeatable these are ...

• Reliability of transcranial magnetic stimulation and H-reflex measurement during balance perturbation tasks 

  Hu, Nijia; Avela, Janne; Kidgell, Dawson J.; Nevanperä, Samuli; Walker, Simon; Piirainen, Jarmo M. (Frontiers Media SA, 2022)

  Following ankle movement, posterior balance perturbation evokes short- (SLR ∼30–50 ms), medium- (MLR ∼50–60 ms), and long-latency responses (LLR ∼70–90 ms) in soleus muscle before voluntary muscle contraction. Transcranial ...

• Voimaharjoittelun vaikutukset dynaamiseen ja staattiseen tasapainoon nuorilla ja ikääntyneillä 

  Allonen, Juho (2017)

  Tasapainolle ei ole olemassa universaalia määritelmää mutta se tiedetään, että sitä kontrolloivat useat eri mekanismit. Ikääntyminen aiheuttaa siinä heikkenemistä, joka aiheutuu muutoksista sekä sensorisissa että motorisissa ...
