Changes in Vertebral Artery Hemodynamics Associated With McKenzie Therapeutic Cervical Movements: An Exploration Using Duplex Ultrasound Imaging.

Objective: The purpose of this study was to explore vertebral artery hemodynamic changes associated with McKenzie therapeutic cervical movements in healthy individuals.

Methods: A single-group repeated-measure design was used to examine 20 healthy participants aged 22.05 (1.

Importance Attributed to Cardiovascular and Pulmonary Competencies by Public Sector Physical Therapists in Kuwait: A Population-based Exploratory Study.

Background And Purpose: Indications for cardiovascular and pulmonary (CVP) physical therapy competencies are changing with the epidemic of non-communicable diseases in Kuwait, particularly lifestyle-related conditions. The degree to which the country's physical therapists (PTs) perceive the importance of CVP competencies (assessment/evaluation and clinical and laboratory investigation interpretation) in professional practice is relevant. Our study objectives were to (1) explore the importance attributed to specific CVP competencies by PTs to professional practice in Kuwait and (2) establish whether these are related to practitioner traits, for example, age, sex, practice setting and specialty.

To establish whether McKenzie lumbar flexion and extension mobility exercises performed in lying affect central as well as systemic hemodynamics: a crossover experimental study.

Objective: Examine systemic and central hemodynamic responses following McKenzie lumbar flexion and extension mobility exercises performed in lying (FIL and EIL).

Design: Crossover experimental study.

Setting: Clinical laboratory.

Evaluation of the McKenzie intervention for chronic low back pain by using selected physical and bio-behavioral outcome measures.

Objectives: To assess the bio-behavioral and physical performance characteristics of individuals with chronic low back pain who demonstrated the pain centralization phenomenon and received the McKenzie intervention using selected bio-behavioral and physical performance measures at intake and at 5 weeks and 10 weeks after treatment.

Design: A prospective cohort study with assessment at baseline and 2 follow-ups after completion of the McKenzie intervention.

Setting: Outpatient orthopedic physical therapy clinics.

The relationship of anticipated pain and fear avoidance beliefs to outcome in patients with chronic low back pain who are not receiving workers' compensation.

Study Design: A prospective, interventional case series design.

Objectives: To determine the degree to which preintervention measures of anticipated pain and fear avoidance beliefs predict outcome after intervention for patients with delayed recovery from low back pain (LBP) for which they are not receiving workers' compensation.

Summary Of Background Data: Anticipated pain and fear avoidance beliefs have been suggested as important factors for the classification and treatment of patients with LBP.

Differences in back extensor strength between smokers and nonsmokers with and without low back pain.

Study Design: Cross-sectional study comparing isometric lumbar extensor strength (ILES) in individuals who smoke and nonsmokers with and without low back pain (LBP).

Objectives: To examine the differences in ILES between individuals who smoke and nonsmokers with and without LBP.

Background: Given the evidence for general muscle weakness in individuals who smoke and in individuals with LBP, we were interested in examining the interrelationships between back strength, in particular ILES, and LBP in individuals who smoke and nonsmokers.

The influence of pain and pain-related fear and disability beliefs on walking velocity in chronic low back pain.

The purpose of this study was to examine the influence of anticipation of pain, sensory perception of pain and pain-related fear and disability beliefs on the gait characteristics of patients with chronic low back pain (CLBP). Thirty-one individuals with CLBP (16 men and 15 women) and 24 healthy individuals (11 men and 13 women) between 20 to 56 years of age participated in this study. Anticipated pain and the pain actually felt were measured with two separate visual analogue scales before and after preferred and fast walking performances.
