Determinants of previous termfunctional balance and mobilitynext term have rarely been investigated in geriatric wards. This study examined if leg muscle previous termstrengthnext term correlates to previous termfunctional balance and mobilitynext term among geriatric inpatients. Fifty inpatients, 29 women and 21 men (mean age 79.6 years) were included. previous termFunctional balancenext term was assessed with the Berg previous termBalancenext term Scale (BBS) and previous termmobilitynext term was assessed with the Physiotherapy Clinical Outcome Variable Scale (COVS). previous termStrengthnext term in the leg extension muscles was measured as 1 Repetition Maximum (1RM) in a leg press and previous termstrengthnext term in the ankle muscles was measured with Medical Research Council grades (MRC, 0–5). The sum scores, and most of the single items, of the BBS and the COVS significantly previous termcorrelatednext term to 1RM/body weight, ankle dorsiflexion, and plantar flexion. In a stepwise multiple regression, ankle dorsiflexion and 1RM/body weight together accounted for 39% of the variance of the BBS and 41% of the variance of the COVS. Estimated values of the BBS and the COVS can be calculated from the equation. In clinical work, the knowledge about how leg muscle previous termstrengthnext term associates with previous termbalance and mobilitynext term may be useful in analyzing underlying causes of reduced previous termbalance and mobilitynext term function, and in planning rehabilitation programs.
