Postural control in male patients with hip osteoarthritis

Impairment of Dynamic Single‐Leg Balance Performance in Individuals With Hip Chondropathy

“…We did not find any significant differences in COP measures between the hip chondropathy and control groups during the StandEC task, which is in agreement with previous research (10). However, the effects of hip OA on static balance are inconclusive, since evidence also reports improvements in double-leg standing in people with hip OA following total hip arthroplasty (11).…”

“…Evidence of impaired static balance is less convincing (10,11). Since lateral balance is controlled by coordinated hip muscle activity and trunk movement (12), reduced hip muscle strength (13,14) and limited hip joint range of motion (ROM) observed in those with hip OA may contribute to impaired balance control.…”

Acute experimental hip muscle pain alters single-leg squat balance in healthy young adults

“…Consistent with young adults with hip chondropathy [8] and older males with hip OA [26], experimental pain did not influence CoP measures for the StandEC task. Further, static single-leg standing places lower mechanical demand on gluteus medius, relative to dynamic tasks such as a single-leg squat [27], and therefore, changes in balance due to experimental hip muscle pain, may be more evident in dynamic tasks.…”

Relevance of orthostatic posturography for clinical evaluation of hip and knee joint arthroplasty patients

“…Accepting the hypothesis that the CoP planar migration is stationary, about 40 posturographic parameters (PPs) are commonly adopted to describe the statistical properties of the CoP, in the time and frequency domains [5][6][7][8]. The robustness of PPs has been clearly assessed [9][10][11], but there are contrasting conclusions in literature about the sensitivity and clinical significance of PPs in subjects affected by osteoarthritis (OA), THA or TKA [12][13][14][15][16][17][18][19].…”
