The weakness typically becomes progressively more noticeable rather than appearing once and disappearing. Hand weakness and clumsiness are among recognized early symptoms of ALS. ([Mayo Clinic][1])
## 2. Weakness in the Foot, Ankle, or Leg
Possible early signs include:
* Difficulty lifting the front of the foot
* Repeatedly catching the toes while walking
* An ankle that feels unusually weak
* Increasing difficulty climbing stairs
Mayo Clinic lists weakness in the legs, feet, or ankles among common early presentations. ([Mayo Clinic][1])
## 3. Frequent Tripping or Falling
Unexplained trips and falls can occur when leg or foot muscles become weaker.
Someone who previously walked normally may begin:
* Stumbling on flat surfaces
* Catching a foot on rugs or steps
* Losing balance more often
* Having trouble with routine walking
