BACKGROUND: Studies investigating posteroanterior (PA) forces in spinal stiffness assessment have shown relationships to spinal level, body type, and lumbar extensor muscle activity. Such measures may be important determinants in discriminating between patients who are asymptomatic and those who have low back pain. However, little objective evidence is available concerning variations in PA stiffness and their clinical significance. Moreover, although several studies have assessed only load input in relation to stiffness, a more complete assessment based on dynamic stiffness measurements (force/velocity) and concomitant neuromuscular response may offer more information concerning mechanical properties of the low back...

"Core" exercise is a basic part of many physical training regimens with goals ranging from rehabilitation of spine and knee injuries to improving athletic performance. Core stiffness has been proposed to perform several functions including reducing pain by minimising joint micro-movements, and enhancing strength and speed performance. This study probes the links between a training approach and immediate but temporary changes in stiffness. Passive and active stiffness was measured on 24 participants; 12 having little to no experience in core training (inexperienced), and the other 12 being athletes experienced to core training methods; before and after a 15 min bout of isometric core exercises...

BACKGROUND: Low back pain (LBP) is an important health problem in all developed countries and is associated with high levels of disability. Evidence-based clinical practice guidelines usually recommend different physical therapy interventions to manage this condition. However, those interventions usually result in small to moderate clinical effects. Recent studies suggest that interventions based on subgroup classifications may improve the effect sizes compared with rehabilitation programs where the same interventions were applied to all patients...

The treatment-based classification (TBC) system for the treatment of patients with low back pain (LBP) has been in use by clinicians since 1995. This perspective article describes how the TBC was updated by maintaining its strengths, addressing its limitations, and incorporating recent research developments. The current update of the TBC has 2 levels of triage: (1) the level of the first-contact health care provider and (2) the level of the rehabilitation provider. At the level of first-contact health care provider, the purpose of the triage is to determine whether the patient is an appropriate candidate for rehabilitation, either by ruling out serious pathologies and serious comorbidities or by determining whether the patient is appropriate for self-care management...

BACKGROUND CONTEXT: Transcutaneous neuromuscular electrical stimulation (NMES) can stimulate contractions in deep lumbar stabilizing muscles. An optimal protocol has not been devised for the activation of these muscles by NMES, and information is lacking regarding an optimal stimulation point on the abdominal wall. PURPOSE: The goal was to determine a single optimized stimulation point on the abdominal wall for transcutaneous NMES for the activation of deep lumbar stabilizing muscles...

STUDY DESIGN: Randomized controlled trial. OBJECTIVE: To determine the validity of a previously suggested clinical prediction rule (CPR) for identifying patients most likely to experience short-term success following lumbar stabilization exercise (LSE). Background Although LSE is commonly used by physical therapists in the management of low back pain, it does not seem to be more effective than other interventions. A 4-item CPR for identifying patients most likely to benefit from LSE has been previously suggested but has yet to be validated...

OBJECTIVE: To review the specificity of exercises designed to condition the lumbar extensor musculature (ie, lumbar erector spinae and multifidus). METHODS: A review of studies examining effects of exercises designed to condition the lumbar extensors was conducted. Included were studies that examined the acute activation and chronic adaptation of the lumbar extensor musculature in response to benches and roman chair trunk extensions, free weights exercises (ie, deadlifts, squats, good-mornings, etc), floor and stability ball exercise (ie, trunk extensions, bridging, four-point kneeling, etc) and resistance machines (ie, those with and without pelvic restraints)...

STUDY DESIGN: An in vitro biomechanical study. OBJECTIVE: To perform in vitro biomechanical testing on a lumbar spine using a 6-degree-of-freedom machine. To compare the range of motion (ROM), intradiscal pressure, and facet force of different 3-level dynamic stabilization constructs with traditional rigid constructs. To determine the effect of decreasing the stiffness of the dynamic construct on the various parameters. SUMMARY OF BACKGROUND DATA: Dynamic stabilization systems are a surgical option that may minimize the development of adjacent segment disease...

OBJECTIVE: To compare the effects of lumbar stabilization exercises and lumbar dynamic strengthening exercises on the maximal isometric strength of the lumbar extensors, pain severity and functional disability in patients with chronic low back pain (LBP). METHODS: Patients suffering nonspecific LBP for more than 3 months were included prospectively and randomized into lumbar stabilization exercise group (n=11) or lumbar dynamic strengthening exercise group (n=10)...

STUDY DESIGN: Interrater reliability. OBJECTIVES: (1) To examine the interrater reliability of an existing clinical prediction rule (CPR) to predict the success of lumbar stabilization exercises (LSE), and (2) to examine the interrater reliability of 4 clinical tests that may be useful in determining the need for LSE. BACKGROUND: Physical therapists commonly use LSE to manage patients with low back pain. The clinical efficacy of LSE is unclear...

Understanding the clinical characteristics of patients with low back pain (LBP) who display improved lumbar multifidus (LM) muscle function after spinal manipulative therapy (SMT) may provide insight into a potentially synergistic interaction between SMT and exercise. Therefore, the purpose of this study was to identify the baseline historical and physical examination factors associated with increased contracted LM muscle thickness one week after SMT. Eighty-one participants with LBP underwent a baseline physical examination and ultrasound imaging assessment of the LM muscle during submaximal contraction before and one week after SMT...

STUDY DESIGN: Experimental laboratory study. OBJECTIVES: To measure trunk muscle activity using wire electrodes during lumbar stabilization exercises and to examine if more effective exercises to activate the deep trunk muscles (local muscles) exist. BACKGROUND: Lumbar stabilization exercises are performed to improve motor control of trunk muscles. However, the magnitude of activation of local muscles during lumbar stabilization exercises is not clear...

BACKGROUND AND PURPOSE: A clinical prediction rule (CPR) has been reported to identify patients with low back pain who are likely to benefit from stabilization exercises. The aim of this study was to characterize the spinal motion, using digital fluoroscopic video, of a subgroup of subjects with low back pain. SUBJECTS: Twenty subjects who were positive on the CPR were compared with 20 control subjects who were healthy. METHODS: The magnitude and timing of lumbar sagittal-plane intersegmental angular and linear displacement were assessed...

OBJECTIVE: To determine whether the abdominal hollowing technique is more effective for lumbar spine stabilization than a full abdominal muscle cocontraction. DESIGN: Within-subject, repeated-measures analysis of variance was used to examine the effect of combining each of 4 loading conditions with either the hollow or brace condition on the dependent variables of stability and compression. A simulation was also conducted to assess the outcome of a person activating just the transversus abdominis during the hollow...
