Pressure release technique versus placebo applied to cervical and masticatory muscles in patients with chronic painful myofascial temporomandibular disorder: A randomised clinical trial.

BACKGROUND: The therapeutic approach to myofascial TMD should focus on pain relief and rehabilitation of function. OBJECTIVE: This study investigated whether pressure release technique (PRT) is effective for reducing pain in people with chronic myofascial temporomandibular disorders (TMD). METHODS: A single-blinded randomised parallel-group trial, with 3 months follow-up was conducted. A total of 72 patients were randomly allocated to receive PRT or sham PRT. Primary outcome was pain assessed with a visual analogue scale (VAS). Secondary outcomes included pressure pain thresholds (PPTs), range of opening of the mouth (ROM), Neck Disability Index (NDI), Pain Catastrophizing Scale (PCS), Tampa Scale for Kinesiophobia (TSK-11), State-Trait Anxiety Index (STAI) and State-Trait Depression Index (ST-DEP). All parameters were assessed at baseline, at the end of the treatment and at 3 months follow-up. Statistical analysis was performed by ANOVA. RESULTS: There were significant main effects of time, group and interaction between time and group (F ≥ 21.92; p < .001) on VAS pain. Post hoc tests showed a significant reduction in VAS pain scores in the PRT group (≥31.9%; p < .001). Effect sizes were moderate in the PRT group at all follow-up periods (≥1.25 Cohen's d). Also, there were significant effects of time in secondary outcomes (F ≥ 9.65; p < .001), and there were also interactions between time and group (F ≥ 3.82; p < .002) with better effects in the PRT group. CONCLUSIONS: The inclusion of PRT to conventional management with occlusal splints and self-care management appears to be effective to improve self-reported levels of pain in patients with chronic myofascial TMD pain.

Effectiveness of the physical therapy Godelive Denys-Struyf method for nonspecific low back pain: primary care randomized control trial.

STUDY DESIGN: A simple blind, random controlled clinical trial. OBJECTIVE: To assess the effectiveness of physiotherapy treatment based on the muscular and articular chains Godelive Denys-Struyf (GDS) method for nonspecific low back pain (LBP) in primary care. SUMMARY OF BACKGROUND DATA: Despite a systematic review by the European COST ACTION B13 "Low back pain: guidelines for its management," there are still many unresolved questions regarding the effectiveness of the different physical therapy treatments used for LBP. SETTING: 21 physicians and physiotherapists in 7 Primary Care Centers and 6 researches in the Complutense University of Madrid (Spain). PARTICIPANTS: 137 patients diagnosed with nonspecific LBP. METHODS: The control group underwent 15 sessions of conventional physiotherapy in Primary Care Centers, and the experimental group received 15 GDS treatment sessions. Pain was evaluated by Visual Analogical Scale (VAS), functional disability by Oswestry questionnaire, and quality of life by the physical and mental components of SF-36 questionnaire. Outcome measures were assessed before treatment (A1), at the end of treatment (A2), and at 3 months (A3), and 6 months (A4) of follow-up. RESULTS: Repeated measures analysis of variance revealed that at the end of treatment and 3 months later, subjects in both groups showed less pain, reduced functional disability, and an improved quality of life, though improvements were greater in the GDS group.Six months after treatment, patients in the GDS group continued to show reduced pain (VAS(A4-A1) = -3.54, 95% CI: -4.18 to -2.90) while VAS scores in the control group returned to initial values (VAS(A4-A1) = 0.15, 95% CI: -0.36 to 0.67). CONCLUSION: Treatment of nonspecific LBP using the GDS method provides greater improvements in the midterm (6 months) in terms of the pain, functional ability, and quality of life perceived by patients than the conventional treatment based administered in primary care.
