Postural instability
This symptom usually occurs in the later stages of the disease and is a balancing issue.
A person may find it difficult to maintain an upright position and is unstable when standing.
This instability leads to a person with Parkinson’s to often fall over.
Freezing
This is when a person feels as if their feet are glued to the ground, especially when turning or changing direction.
Freezing is also when a person feels like their lower half is stuck but the top half is able to move.
Freezing also affects activities such as speaking or when doing a repetitive movement such as writing.
