The Relationship of Knee and Ankle Weakness to Falls in Nursing Home Residents: An Isokinetic Study
Abstract
The strength of the knees and ankles of a group of nursing home residents with a history of falls was compared to age‐matched controls. Peak torque (PT) and power (POW) were recorded at two limb velocities (60°/s and 220°s) on a Cybex II Isokinetic dynamometer for four muscle groups: knee extensors, knee flexors, ankle plantar flexors and ankle dorsiflexors. The PT and POW of falters were significantly decreased for all four muscle groups in comparison to controls, with the ankles showing the greatest decrements. Although POW in fullers was significantly lower at the higher velocity in both joints, the decrease was most prominent in the ankles. Dorsiflexion POW production in falters was the most affected of all the motions (7.5 times less than the control value). At the higher, more functional limb velocities, ankle weakness particularly involving the dorsiflexors appears to be an important factor underlying poor balance.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
