Function of 37 patients with osteotomy of the greater trochanter during total hip replacement (41 hips) is compared to function of 38 patients (41 hips) without osteotomy. Subjective assessments and cane force measurements were slightly more favorable in the group without osteotomy. Objective measurement of hip motion, hip abductor and adductor muscle strength, weight distribution during standing, and multiple components of free-speed and fast walking showed no statistically significant differences between performance of the groups with and without osteotomy before surgery or 6 months or 2 years after. This suggests that osteotomy provides no functional advantages to the patient beyond those obtained in total hip replacements without osteotomy.

Effects of lifestyle activity level on anticipatory locomotor adjustments for pedestrian circumvention: an exploratory study.
Exp Brain Res
January 2025
School of Rehabilitation Sciences, Université Laval, Quebec, Canada.
Navigating public environments requires adjustments to one's walking patterns to avoid stationary and moving obstacles. It is known that physical inactivity induces alterations in motor capacities, but the impact of inactivity on anticipatory locomotor adjustments (ALA) has not been studied. The purpose of the present exploratory study was to compare ALAs and related muscle co-contraction during a pedestrian circumvention task between active (AA) and inactive young adults (IA).

The response to pericapsular soft tissue and pelvic realignment therapy may be partially predicted by the relevant factors influencing the program's response of the candidates with hip osteoarthritis for joint replacement.

Objective: To explore the risk factors for discontinuation of pericapsular soft tissue and pelvic realignment (PSTP-R) therapy derived from Shiatsu in the candidates with osteoarthritis for total hip replacement (THR) (i.e., candidates for total hip replacement) treated from 2017 to 2020, and to identify the effect modifiers of PSTP-R therapy for patients who continued therapy for 6 months.

We aimed to evaluate the effects of prepartum supplementation of different I sources (Ascophyllum nodosum [ASCO] meal and ethylenediamine dihydroiodide [EDDI]) on colostrum yield of cows, and blood concentrations of glucose, BHB, and thyroid hormones and growth of dairy calves. Forty multiparous Holstein cows were blocked by lactation number and expected calving date and assigned to 1 of 4 treatments 28 d before parturition: (1) EDDI supplemented (11 mg/d) to a basal diet to meet the NRC (2001) I concentration of 0.5 mg of I/kg of DMI (control = CON [0 g/d of ASCO meal]; actual I concentration = 0.
