Proprioceptive neuromuscular facilitation (PNF) techniques are based on which principle?
Answer: Sherrington's law of successive induction
PNF is based on Sherrington's neurophysiological principles including successive induction and reciprocal inhibition.
Which balance system is most relied upon when standing on an unstable surface with eyes closed?
Answer: Vestibular system
When both visual and somatosensory inputs are reduced or unreliable, the vestibular system becomes the primary balance reference.
A patient with multiple sclerosis has fatigue that worsens with increased body temperature. This phenomenon is called:
Answer: Uhthoff's phenomenon
Uhthoff's phenomenon describes the temporary worsening of MS symptoms with increased body temperature.
In a patient with a lower motor neuron lesion, which finding is expected?
Answer: Flaccid paralysis
Lower motor neuron lesions cause flaccid paralysis, hyporeflexia, and muscle atrophy due to loss of direct muscle innervation.
The two-point discrimination test assesses which sensory modality?
Answer: Fine touch and tactile discrimination
Two-point discrimination tests the ability to detect two distinct tactile points, assessing the density of cutaneous mechanoreceptors.
Which developmental milestone is typically achieved at 9–10 months of age?
Answer: Pulling to stand
Most infants pull themselves to a standing position by 9–10 months as part of normal gross motor development.
