BACKGROUND Temporal-spatial gait parameters improve following total knee arthroplasty (TKA) but lower limb kinematics and moments fail to match those of age-matched healthy individuals. The aim of this study was to determine whether quadriceps strength, clinical measures of knee function, lower limb kinematics, and joint moments improve following… (More)
INTRODUCTION Intramuscular adipose tissue (IMAT) is a potential contributor to declining force production and may be related to impaired central activation; therefore, the purpose of this report is to describe IMAT composition and its association with central activation in older adults. The central activation ratio (CAR) of the knee extensors was assessed… (More)
Rehabilitation services are less-studied aspects of the management following total knee arthroplasty (TKA) despite long-term suboptimal physical functioning and chronic deficits in muscle function. This paper describes the preliminary findings of a six-week (12 session) eccentrically-biased rehabilitation program targeted at deficits in physical function… (More)
INTRODUCTION Quadriceps weakness is one of the primary post-operative impairments that persist long term for patients after total knee arthroplasty (TKA). We hypothesized that early gait muscle recruitment patterns of the quadriceps and hamstrings with diminished knee performance at 3months after surgery would be related to long-term quadriceps strength at… (More)
To compare magnetic resonance imaging (MRI) and ultrasonography (US) in the detection of joint inflammation of rheumatoid arthritis (RA), 6 patients with RA were examined by US and low-field 0.3-T nonenhanced dedicated extremity MRI (compacTscan). All patients were females, with mean age of 50.2 years, mean disease duration of 13.5 years, and mean disease… (More)
An extension theorem for [n, k, d] q codes with gcd(d, q) = 2 Abstract As a continuation of Maruta [Finite Fields Appl. 10 (2004), 674–685], we investigate the extendability of [n, k, d] q codes with d ≡ −2 (mod q) whose weights are congruent to 0, −1 or −2 (mod q) for even q ≥ 4. We show that such codes are extendable for all even q ≥ 8, giving a new… (More)
For an [n, k, d] 3 code C with gcd(d, 3) = 1, we define a map w G from Σ = PG(k − 1, 3) to the set of weights of codewords of C through a generator matrix G.
Overview ♣ The (2, 1)-extendability of [n, k, d] 3 codes with gcd(3, d) = 1 is investigated geometrically for 3 ≤ k ≤ 5.
