Center of rotation locations during lumbar spine movements: a scoping review protocol.

Objective: The objective of this review is to identify and map current literature describing the center of rotation locations and migration paths during lumbar spine movements.

Introduction: Altered lumber spine kinematics has been associated with pain and injury. Intervertebral segments' center of rotations, the point around which spinal segments rotate, are important for determining the features of lumbar spine kinematics and the potential for increased injury risk during movements.

Should Preoperative Fascia Iliaca Block Be Used for Hip Arthroscopic Labral Repair and Femoroacetabular Impingement Treatment? A Prospective Single Blinded Randomized Study.

Purpose: To evaluate the analgesic effect of preoperative fascia iliaca block on postoperative morphine equivalent dose, pain level, and patient satisfaction for patients electing to undergo primary hip arthroscopic labral repair with osteochondroplasty.

Methods: This prospective study included 60 patients (fascia iliaca block group: n = 27; control group: n = 33) undergoing elective arthroscopic hip surgery by a single board-certified orthopedic surgeon, fellowship trained in hip arthroscopy. Participants for the study included patients older than 10 years of age and younger than 85 years of age, American Society of Anesthesiologists classifications I to III, diagnosed with symptomatic femoroacetabular impingement, and/or hip labral tear, and/or cartilage damage, and electing to undergo arthroscopic hip surgery.

Effectiveness of Nanolime as a Stone Consolidant: A 4-Year Study of Six Common UK Limestones.

Protecting stone buildings from weathering and decay is a major challenge in the conservation of built heritage. Most of the stone consolidants currently available are well suited to silicate stones, but are less compatible with limestone. In this paper we present for the first time the results over a 4-year period of various consolidation treatments carried out using nanolime on 6 of the most representative and significant stones used in historic buildings in the United Kingdom.

A noninvasive hair sampling technique to obtain high quality DNA from elusive small mammals.

Noninvasive genetic sampling approaches are becoming increasingly important to study wildlife populations. A number of studies have reported using noninvasive sampling techniques to investigate population genetics and demography of wild populations. This approach has proven to be especially useful when dealing with rare or elusive species.

The grammatical morpheme deficit in moderate hearing impairment.

Background: Much remains unknown about grammatical morpheme (GM) acquisition by children with moderate hearing impairment (HI) acquiring spoken English.

Aims: To investigate how moderate HI impacts on the use of GMs in speech and to provide an explanation for the pattern of findings.

Methods & Procedures: Elicited and spontaneous speech data were collected from children with moderate HI (n = 10; mean age = 7;4 years) and a control group of typically developing children (n = 10; mean age = 3;2 years) with equivalent mean length of utterance (MLU).

An investigation of weak syllable processing in deaf children with cochlear implants.

In this study the influence of prosodic foot structure on the processing of weak syllables in children with cochlear implants (CI) was investigated. A battery of tests investigating processing of weak syllables in single and multi-word utterances was carried out on four groups of children: 15 children with CI developing spoken language as expected (Main CI); five children with CI reported to have additional speech and language problems; 15 age matched; and 15 language matched (LM) children with normal hearing (NH). Children in the main CI and, to a lesser extent, the LM groups processed footed weak syllables preferably over unfooted weak syllables (particularly as memory load increased).
