BACKGROUND Historically, persons scheduled for total knee arthroplasty (TKA) have reported severe pain with low demand activities such as walking, but recent data suggests that TKA recipients may have less preoperative pain. Little is known about people who elect TKA with low levels of preoperative pain. To better understand current TKA utilization, we evaluated the association between preopera...

BACKGROUND Athletes often take androgenic steroids in an attempt to increase their strength. The efficacy of these substances for this purpose is unsubstantiated, however. METHODS We randomly assigned 43 normal men to one of four groups: placebo with no exercise; testosterone with no exercise; placebo plus exercise; and testosterone plus exercise. The men received injections of 600 mg of test...

PURPOSE Leg muscle strength and power are increased after whole-body vibration (WBV) exercise. These effects may result from increased neuromuscular activation during WBV; however, previous studies of neuromuscular responses during WBV have not accounted for motion artifact. METHODS Sixteen healthy adults performed a series of static and dynamic unloaded squats with and without two different ...

Objective: In recent times, there have been a shift in the focus of health sector towards respectful maternity care. The concept care is inclined client centred with right women to make informed decisions concerning birth choices. woman decide which position adopt during childbirth has limited supine most service centres and hospital settings. This study sought investigate pregnant women’s pref...

The aims of this study were to compare the validity of two accelerometers with a force plate and to determine the influence of the sensor’s point of attachment on the assessment of squat jump performances. Nine male subjects performed a number of squat jumps (n = 38) on a force plate, either with a Myotest or Mensense system attached to their hips and backs. For evaluation purposes, twoway ANOV...

On 21 April 2011, violence flared in the Stokes Croft area of Bristol following a police raid on a squat. Media coverage suggested that this riot was a manifestation of the campaign against the opening of a Tesco supermarket in the area. Footage later emerged on YouTube, which appeared to support claims by local residents that the violence was caused by heavy-handed police tactics rather than t...

The purpose of this paper is to explain how and why performance in explosive movements depends on musculoskeletal properties and coordination. First, a musculoskeletal model is presented that has muscle stimulation as only independent input, and allows for forward simulation of explosive movements. Subsequently, a theoretical framework is presented for analyzing simulation results: performance ...
