An accidental fall is defined as a fall "due to slipping or tripping which results in injury".[1]

Falls in the elderly

At least a third of persons aged 65 years or more fall each year, with 10% leading to injury.[2]

Assessing risk

The presence of various medical conditions and the results of functional tests can assess the risk of falling.[3] Examples of such tests are Gait velocity and the Timed-Up-and-Go tests.[4] A Timed-Up-and-Go test of < 15 seconds suggests a low risk of falling.[5] In the Timed-Up-and-Go test "patients to stand up from a chair, walk a short distance, turn around, return, and sit down again."[6]

Causes

Buckling, or sudden giving way, of the knees is associated with osteoarthritis of the knees and quadriceps muscle weakness.[7]

Chronic muscle pain may be associated with an increased risk of falls.[8]

Wearing multifocal eyeglasses may increase falls.[9]

Medications

Medications[10], especially psychotropic[11] and cardiac[12] are associated with increased risk of falling.

Prevention

Individual interventions

One randomized controlled trial reported that tai chi, one hour per week for 16 weeks, can prevent falls in patients aged 60 or more.[13]

A meta-analysis by the Cochrane Collaboration found benefit among cummunity-dwelling persons from:[14]

  • Individually targeted exercise or physical therapy consisting of strength training, balance, and walking.
  • Home safety interventions.

According to a subsequent meta-analysis by the Cochrane Collaboration, the role of modifying the home environment for the reduction of injuries has not been established.[15]

Withdrawing psychotropics mediations may prevent falls.[16][17]

Medications

Vitamin D may prevent falls by increasing muscle strength.[18]

Multifactorial interventions

A meta-analysis by the Cochrane Collaboration found benefit among cummunity-dwelling persons from multidisciplinary, multifactorial, health, or environmental risk-factor screening or intervention programs.[14] A more recent randomized controlled trial confirms this[19][20] although not all trials have shown benefit.[21]
