Chronic neck pain is associated with sensorimotor dysfunctions, which may develop symptoms, affect daily activities, and prevent recovery. Feasible, reliable, and valid objective methods for the assessment of sensorimotor functions are important to identify movement impairments and guide interventions. The aim of this study was to investigate the discriminative validity of a clinical cervical movement sense test, using a laser pointer and an automatic video-based scoring system.

The aim of this study was to explore and describe the physiotherapy treatment experiences of persons with persistent musculoskeletal pain. Eleven participants with persistent musculoskeletal pain in the back, neck, or shoulders were included in the study. Data was collected via semi-structured interviews and were analysed with qualitative content analysis.

Background Context: Assessment of posture and lumbopelvic alignment is often the main focus in the classification and treatment of patients with low back pain (LBP). However, little is known regarding the effects of motor control interventions on objective measures of lumbopelvic alignment.

Purpose: The primary aim of this study was to describe the variation of sagittal lumbopelvic alignment in patients with nociceptive mechanical LBP.

Expectations of physiotherapy treatment of patients with persistent pain have been shown to influence treatment outcome and patient satisfaction, yet this is mostly explored and described in retrospective. The aim of the study was to explore and describe the expectations people with persistent pain have prior to physiotherapy treatment. Ten participants with persistent musculoskeletal pain from the back, neck, or shoulders were included in the study.

Background: Patients' participation in their health care is recognized as a key component in high-quality health care. Persons with persistent pain are recommended treatments with a cognitive approach from a biopsychosocial explanation of pain, in which a patient's active participation in their rehabilitation is in focus. Web-based interventions for pain management have the potential to increase patient participation by enabling persons to play a more active role in rehabilitation.

Study Design: Randomized controlled trial.

Objective: The aim of this study was to compare the effects of low-load motor control (LMC) exercises and a high-load lifting (HLL) exercise, on lumbar multifidus (LM) thickness on either side of the spine and whether the effects were affected by pain intensity or change in pain intensity.

Summary Of Background Data: There is evidence that patients with low back pain (LBP) may have a decreased size of the LM muscles with an asymmetry between sides in the lower back.

Background: Web-based interventions with a focus on behavior change have been used for pain management, but studies of Web-based interventions integrated in clinical practice are lacking. To emphasize the development of cognitive skills and behavior, and to increase activity and self-care in rehabilitation, the Web Behavior Change Program for Activity (Web-BCPA) was developed and added to multimodal pain rehabilitation (MMR).

Objective: The objective of our study was to evaluate the effects of MMR in combination with the Web-BCPA compared with MMR among persons with persistent musculoskeletal pain in primary health care on pain intensity, self-efficacy, and copying, as part of a larger collection of data.

Objective: The aim of this study was to compare the effects of a high load lifting exercise with low load motor control exercises on pain intensity, disability and health-related quality of life for patients with mechanical low back pain.

Design: A randomized controlled trial.

Subjects: Patients with mechanical low back pain as their dominating pain mechanism.

Background: Disruption of cortical representation, or body schema, has been indicated as a factor in the persistence and recurrence of low back pain (LBP). This has been observed through impaired laterality judgment ability and it has been suggested that this ability is affected in a spatial rather than anatomical manner.

Objectives: We compared laterality judgment performance of foot and trunk movements between people with LBP with or without leg pain and healthy controls, and investigated associations between test performance and pain.

Study Design: Randomized controlled trial.

Background: Low back pain is a common disorder. Patients with low back pain frequently have aberrant and pain-provocative movement patterns that often are addressed with motor control exercises.

Recent studies have indicated that the deadlift exercise may be effective in decreasing pain intensity and increasing activity for most, but not all, patients with a dominating pattern of mechanical low back pain. This study aimed to evaluate which individual factors measured at baseline could predict activity, disability, and pain intensity in patients with mechanical low back pain after an 8-week training period involving the deadlift as a rehabilitative exercise. Thirty-five participants performed deadlift training under the supervision of a physical therapist with powerlifting experience.

Obstructive sleep apnea/hypopnea syndrome (OSAHS) is a medical condition that has received significant attention within the medical community and mainstream media due to its potentially serious physiological consequences and relatively frequent occurrence within the general population. From the military perspective, the impact on individual readiness for deployment, and the potential degradation of performance in critically important military duties, often results in tremendous expenditures of training resources, time, and expertise to replace the military member with a suitable substitute or release of the individual from active duty. This article reviews common surgical techniques for clinical management of OSAHS patients in a presentation format for primary care and sleep medicine specialists, as well as surgeons interested in the philosophies of surgical management of sleep disordered breathing.

Intratracheal ectopic thyroid tissue is a rare finding, with few cases reported in the literature. Ectopic thyroid tissue results when the thyroid gland fails to descend to its final position during early development. These lesions present in various locations, and the clinician should be aware of their existence and presenting signs and symptoms.

There is ample instructive literature on preoperative analysis of the rhinoplasty patient available to the present day provider. However, the literature does show a paucity of instruction to convert the preoperative analysis into a surgical plan of action. The purpose of this article is to provide a systematic approach to preoperative planning once the analysis has been done.

The purpose of this pilot study was to evaluate sensorimotor functions in patients with chronic neck pain with objective and quantitative methods. A group of 16 patients with chronic idiopathic neck pain of insidious onset or whiplash associated disorders (WAD) was compared to an equally sized group of healthy subjects. Kinematics were investigated during voluntary head rotations by measuring range of motion, variability of range of motion (ROM-Variability), peak velocity, and smoothness of movement (jerk index).

Objectives: Accurate and timely diagnosis for patients with obstructive sleep apnea (OSA) is imperative. Unfortunately, growing interest in this diagnosis has resulted in increased requests and waiting times for polysomnography (PSG), as well as a potential delay in diagnosis and treatment. This study evaluated the accuracy and viability of utilizing SNAP (SNAP Laboratories, LLC, Wheeling, Illinois), a portable home sleep test, as an alternative to traditional PSG in diagnosing OSA.

As in many specialties, otolaryngology is not without diagnosis surrounded by controversy. This report discusses the entity known as the primary branchial cleft carcinoma, which has been argued by some to be no more than metastatic disease of the unknown primary. Although the disease is rare, the consideration of this diagnosis requires careful thought and analysis by the otolaryngologist, pathologist, and radiation oncologist so that a rational treatment plan can be offered to the patient.
