Muscle atrophy is one of many factors contributing to post-stroke hemiparetic weakness. Since muscle force is a function of muscle size, the amount of muscle atrophy an individual muscle undergoes has implications for its overall force-generating capability post-stroke. In this study, post-stroke atrophy was determined bilaterally in fifteen leg muscles… (More)
Upper tract pressure flow studies in four clinically unobstructed ureters with double J stents in situ indicated that urinary flow occurred mainly around the stent and that there was significant vesicorenal pressure transmission. This study examined the dynamics of ureteric urinary flow and morphological effects consequent upon stenting a ureter in vivo. In… (More)
Thirty-one patients with urodynamically proven bladder outflow obstruction were treated with Alfuzosin in a 3-month, double-blind, placebo-controlled study. The irritative symptoms of bladder outflow obstruction were improved significantly in the treatment group, according to both objective and subjective evaluation. There was no objective evidence of a… (More)
Urothelial biopsies from ureters intubated with silicone (11) and other polymer (13) double J stents revealed features of mucous metaplasia in 12/24 cases. These changes were associated with encrustation of the stents and occurred principally in stone-forming patients.
The results of percutaneous pyelolysis in 28 patients are presented. There were 18 successful and 10 unsuccessful cases. The indications for the procedure are defined in the light of this analysis.
Muscle-actuated simulations of pathological gait have the capacity to identify muscle impairments and compensatory strategies, but the lack of subject-specific solutions prevents the prescription of personalized therapies. Conversely, electromyographic-driven models are limited to muscles for which data are available but can capture the true neural drive… (More)
Serum parathyroid hormone (PTH) levels have been measured in 8 patients with hypercalcaemia associated with urological malignancy: 3 renal cell carcinomas, 2 adenocarcinomas of prostate, 2 transitional cell carcinomas of bladder and one transitional cell carcinoma of kidney. Five (63%) of these 8 patients had bone metastases. PTH was detectable in the serum… (More)
A geometric musculoskeletal model of the elbow and wrist joints was developed to calculate muscle moment arms throughout elbow flexion/extension, forearm pronation/supination, wrist flexion/extension and radial/ulnar deviation. Model moment arms were verified with data from cadaver specimen studies and geometric models available in the literature.… (More)
INTRODUCTION Post-stroke muscle weakness is commonly thought to be the result of a combination of decreased voluntary activation and decreased maximum force generating ability (MFGA). We assessed the ability of muscle volumes obtained using MRI to estimate the MFGA of the plantar flexor muscle group in individuals post-stroke. METHODS MRI was used to… (More)
