Multi-joint postural behavior in patients with knee osteoarthritis

The effects of progressive neuromuscular training on postural balance and functionality in elderly patients with knee osteoarthritis: a pilot study

“…together with the weakness of the hamstrings and abductors of the hip23, 24 ) . These alterations may be potentiated by the decrease of the excitability of quadriceps motor units—caused by factors such as joint pain, swelling, and laxity—provoking poor voluntary activation, a proprioceptive deficit, and a decrease of neuromuscular control8, 25,26,27 ) . According to prior investigations, COP variables that present more deterioration are area and velocity in the ML direction, due to deficits in neuromuscular and central nervous system control.…”

Postural Sway, Balance Confidence, and Fear of Falling in Women With Knee Osteoarthritis in Comparison to Matched Controls

“…Postural sway can be assessed by questionnaires, physical/functional tests, and computer software or directly from a force platform [5‐8]. Although the relationship between knee OA and reduced balance is not fully understood, studies have shown that reduced quadriceps function and diminished proprioception are associated with a deterioration in balance (ie, the ability to maintain the center of gravity within a base of support, with minimal sway or maximal steadiness) and confer upon the knee OA patient an increased risk of falls [9‐12].…”

The Impaired Balance Systems Identified by the BESTest in Older Patients With Knee Osteoarthritis

“…In people with those diseases, all the BESTest section scores were lower compared with those of the age‐matched controls. Second, the impaired biomechanics of the knee joints can influence overall postural control, because there are multiple links between joints underlying postural control [28]. Third, pain might directly influence postural control [9,10,26,29].…”
