Review
Manual therapy with or without physical medicine modalities for neck pain: a systematic review.
Manual therapy interventions are often used with or without physical medicine modalities to treat neck pain. This review assessed the effect of 1) manipulation and mobilisation, 2) manipulation, mobilisation and soft tissue work, and 3) manual therapy with physical medicine modalities on pain, function, patient satisfaction, quality of life (QoL), and global perceived effect (GPE) in adults with neck pain. A computerised search for randomised trials was performed up to July 2009. ⋯ We included 19 trials, 37% of which had a low risk of bias. Moderate quality evidence (1 trial, 221 participants) suggested mobilisation, manipulation and soft tissue techniques decrease pain and improved satisfaction when compared to short wave diathermy, and that this treatment combination paired with advice and exercise produces greater improvements in GPE and satisfaction than advice and exercise alone for acute neck pain. Low quality evidence suggests a clinically important benefit favouring mobilisation and manipulation in pain relief [1 meta-analysis, 112 participants: SMD -0.34(95% CI: -0.71, 0.03), improved function and GPE (1 trial, 94 participants) for participants with chronic cervicogenic headache when compared to a control at intermediate and long term follow-up; but no difference when used with various physical medicine modalities.

The extent of cortical neuroplastic changes has been shown to be a key neurophysiological feature that correlates with the level of functional recovery. Therefore, rehabilitation efforts that attempt to maximize cortical reorganization provide the greatest potential for rehabilitation success. This paper reviews the evidence of cortical neuroplastic changes that have been shown to occur in association with experimental or chronic pain disorders. Further, the promising role of novel motor-skill training is discussed in order to best direct the clinician to optimize rehabilitation strategies for patients with musculoskeletal pain disorders.

Palpation of tender points in superficial tissue is commonly undertaken in the management of musculoskeletal pain. The sensory characteristics of digitally tender points (DTPs) have not been defined. This study had two major aims: 1) to characterise 'Strain-Counterstrain' DTPs, using quantitative sensory testing (QST) in participants with low back pain (LBP); 2) to compare corresponding points at lumbar sites in participants with LBP to those without LBP. ⋯ These findings may be indicative of altered central processing of Abeta afferents with terminal receptors at DTPs. Participants with LBP demonstrated elevated cold pain thresholds at lower back sites and at the peripheral shoulder site compared to participants without LBP (p < 0.001). This may also indicate augmented central pain processing in participants with LBP.

Randomized Controlled Trial
Abdominal muscle contraction thickness and function after specific and general exercises: a randomized controlled trial in chronic low back pain patients.
The aim of this study was to assess changes in deep abdominal muscle function after 8 weeks of exercise in chronic low back pain patients. Patients (n = 109) were randomized to specific ultrasound guided, sling or general exercises. Contraction thickness ratio in transversus abdominis (TrA), obliquus internus (OI) and externus (OE), and TrA lateral slide were assessed during the abdominal drawing-in maneuver by b-mode ultrasound. ⋯ Only modest effects in deep abdominal muscle function were observed, mainly due to reduced activation of OI (contraction thickness ratio: 1.42-1.22, p = 0.01) and reduced TrA lateral slide (1.26-1.01 cm, p = 0.02) in the ultrasound group on the left side. Reduced pain was associated with increased TrA and reduced OI contraction ratio (R(2) = 0.18). It is concluded that 6-8 treatments with specific or general exercises for chronic low back patients attained only marginal changes in contraction thickness and slide in deep abdominal muscles, and could only to a limited extent account for reductions in pain.

Comparative Study
Comparison between the reliability levels of manual palpation and pressure pain threshold in children who reported orofacial pain.
The aim of this study was to compare the intra- and inter-rater reliability of pressure pain threshold (PPT) and manual palpation (MP) of orofacial structures in symptomatic and symptom-free children for temporomandibular disorders (TMD). Fourteen children reporting pain in masticatory muscles or the temporomandibular joint and 16 symptom-free children were randomly assessed on three different occasions: by rater-1 in the first and third session and by rater-2 in the second session. The trained raters applied algometry and MP as recommended by the Research Diagnostic Criteria for TMD. ⋯ Excellent intra- and inter-rater reliability levels were observed for PPT values at most of the examined sites for symptom-free children and excellent and moderate reliability levels for children reporting pain. For MP, moderate and poor intra-rater and inter-rater reliability levels were observed for most sites in both groups. Algometry showed higher reliability levels for both groups of children and is recommended for pain assessment in children in association with MP.
