Haemophilia is characterized by intra-articular bleeding, often requiring immobilization, which may result in muscle atrophy and impaired proprioception. The aim of the study was to investigate differences in proprioceptive performance and isometric muscular strength of the lower limbs in haemophilic subjects compared with control subjects. Twelve subjects with severe haemophilia (11 haemophili...

The purpose of this study was to investigate muscle and tendon properties in highly trained sprinters and their relations to running performance. Fifteen sprinters and 15 untrained subjects participated in this study. Muscle thickness and tendon stiffness of knee extensors and plantar flexors were measured. Sprinter muscle thickness was significantly greater than that of the untrained subjects ...

during locomotion or under in vivo conditions, individual locomotor muscles have been found to have functionally diverse roles. Pectoral muscles in flying birds, the abductor muscle in swimming scallops, and myotomes in fish clearly generate power like a motor (Abraham and Loeb, 1985; Johnston, 1991; Biewener et al., 1992; Marsh et al., 1992; Rome et al., 1993), as do the ankle extensors of cat...

The aim of this study was to investigate the change in body composition, leg girths, and muscle strength of patients with incomplete spinal cord injury (SCI) after functional electrical stimulation cycling exercises (FESCE). Eighteen subjects with incomplete SCI were recruited. Each patient received FESCE three times per week for 8 weeks. Body composition, thigh and calf girths of bilateral leg...

OBJECTIVE To provide reference data for peak isometric and isokinetic muscle strength of hamstring and quadriceps muscles in young adult Saudi males. METHODS The strength of left and right quadriceps and hamstrings leg muscles was assessed in 132 college-male students in the campus of King Saud University, Riyadh, Kingdom of Saudi Arabia in the year 2002 using a Cybex machine and a standardiz...

BACKGROUND Racing drivers require multifaceted cognitive and physical abilities in a multitasking situation. A knowledge of their physical capacities may help to improve fitness and performance. OBJECTIVE To compare reaction time, stability performance capacity, and strength performance capacity of élite racing drivers with those of age-matched, physically active controls. METHODS Eight éli...

CASE NUMBER 1. Mr. M. W., a 41-year old white male was admitted to the Victoria General Hospital with complaints of twitching in the left arm and legs, and weakness of the left hand. Seven to eight years prior to admission, the patient noticed dull muscle pain in his arms and legs, lasting four to five days at a time. The pain worsened as the day passed and was neither aggravated nor relieved b...
