Osteopathic manipulative treatment combined with exercise improves pain and disability in individuals with non-specific chronic neck pain: A pragmatic randomized controlled trial

PurposeTo determine effectiveness of osteopathic manipulative treatment combined with stretching and strengthening exercises in the cervical region on pain and disability in individuals with non-specific chronic neck pain.Methods90 adults with non-specific chronic neck pain were randomized to either exercises group (EG, n = 45) or osteopathic manipulative treatment associated with exercises group (OMT/EG, n = 45). The primary outcomes were obtained by the use of Numeric Pain-Rating Scale (NPRS), Pressure Pain Threshold (PPT) and Neck Disability Index (NDI). Secondary outcomes included range of motion (ROM) for cervical spine rotation, Fear-Avoidance Beliefs Questionnaire Work/Physical Activity (FABQ-W/PA) and Pain-self efficacy at two different moments: baseline and 4 weeks after the first treatment. Techniques and dosages of OMT were selected pragmatically by a registered osteopath. Generalized Estimating Equations model (GEE), complemented by the Least Significant Difference (LSD) and the intention-to-treat analysis, was used to assess the clinical outcomes.ResultsAnalysis with GEE indicated that OMT/EG reduced pain and disability more than the EG alone after 4 weeks of treatment with statistically significant difference (p < 0,05), as well as cervical active rotation was significantly improved (p = 0.03). There were no between-group differences observed in Pressure Pain Threshold (PPT) measure, Fear-Avoidance Beliefs Questionnaire and Pain-self efficacy.ConclusionThe association between OMT and exercises reduces pain and improves functional disability more than only exercise for individuals with non-specific chronic neck pain.     

Effects of scapular stabilization and upper limb proprioception as an adjunct to cervical stabilization in chronic neck pain patients: A randomized controlled trial

BackgroundChronic neck pain is a prevalent health condition and a leading cause of disability worldwide. Prompt therapeutic measures are required to overcome this condition.ObjectivesTo evaluate the efficacy of incorporation of scapular stabilization and upper limb proprioceptive exercises to cervical stabilization exercises in patients with chronic neck pain (CNP).DesignA single-blinded randomized controlled design.MethodsA sample of convenience was deployed to recruit twenty-eight patients having CNP (18–45 years) and was randomized into two groups: group A (cervical stabilization exercises group) and group B (scapular stabilization and upper limb proprioceptive exercises group + cervical stabilization exercises). Pain intensity, disability, sleep quality, quality of life, scapular muscles strength and proprioception were assessed at 4 weeks follow up to determine the efficacy of the intervention.ResultsA mixed model ANOVA was used. A statistically significant (p < 0.05) group by time interaction for pain intensity (p = 0.000), scapular muscles strength of all muscles (p = 0.000) was observed. Significant group interaction for absolute error (p = 0.00), for pain (p = 0.001), disability (p = 0.04) and scapular muscle's strength (p = 0.000) was also demonstrated.ConclusionThe results indicated that scapular stabilization and upper limb proprioceptive exercises when combined with cervical stabilization exercises are more beneficial in alleviating pain and disability and improving scapular muscle strength and proprioception in patients with CNP.     

A randomized clinical trial of self-stretching with and without mindful breathing - immediate effect on pressure pain and range of motion in myofascial pain syndrome

IntroductionThe stretching intervention of the current study was applied from several principles and the latest updated method of slowed and synchronized patterns between self-stretching with mindful breathing (MB) and eyes closed period before and after the self-stretching was performed at least four times repeatedly within 150 s per each pose.ObjectiveTo investigate effects of self-stretching in five poses with and without MB on pain and cervical range of motion (CROM).DesignThe study was a randomized clinical trial with a blinded assessor.SettingThe participants were 30 females per group, aged 30–59 years with myofascial pain syndrome (MPS).Main outcome measuresThe participants were evaluated via the pressure pain threshold (PPT) at the upper trapezius muscles and the CROM.ResultsBoth groups showed that the PPT at upper trapezius muscles significantly increased after performing the stretching (p < 0.001). The ROM in the MB group significantly increased in extension, left and right lateral flexion, and left rotation (p < 0.05).ConclusionSelf-stretching with mindful breathing was designed to allow for effects within the shortest time in patients with myofascial pain syndrome. Since this treatment is a non-pharmacological intervention and was considered as part of active self-care, we suggest that this therapy could be used as alternative therapy for patients with MPS.     

Instrument assisted soft tissue mobilization (IASTM) versus stretching: A comparison in effectiveness on hip active range of motion,muscle torque and power in people with hamstring tightness

BackgroundInstrument-assisted soft tissue mobilization (IASTM) is a new technique that has been known to be effective in reducing muscle tightness in athletics. However, little is known about its effect on the range of motion, muscle power, and torque compared to manual stretching among non-athletics. Thus, the study was aimed to compare the effectiveness between IASTM and manual stretching in improving hip flexion active range of motion (ROM), muscle torque and power on hamstring muscle complex (HMC) tightness in one session.MethodTwenty-three young male college students with unilateral hamstring tightness measured via straight leg raising (SLR) test (<65°) were randomly assigned to one of two groups. Twelve participants received the application of IASTM (group 1), and eleven received manual stretching (group 2). Hip flexion active ROM was measured via goniometer, the torque & power of the hamstring muscle were measured using Humac isokinetic dynamometer, before and after both interventions. (ISRCTN17693345).ResultsThere was no significant difference in the improvement of hip flexion active ROM (69.6 ± 6.6 vs 72.5 ± 7.9, p = .34), HMC torque (63.7 ± 14.5 vs 53.2 ± 16.3, p = .14), and HMC power (47.8 ± 11.8 vs 40.9 ± 16.3, p = .34) between group 1 and group 2 respectively. When a comparison was made within each group, significant improvements in hip active flexion ROM was found in both groups (p's < .001), and HMC power was significantly improved in group 1 (p = .04) but not in group 2.ConclusionThe current study findings demonstrate that IASTM was as effective as manual stretching in improving hip flexion active ROM, muscle torque and power among non-athletic people with HMC tightness.     

Effects of sling-based manual therapy on cervicothoracic junction in patients with neck pain and forward head posture: A randomized clinical trial

ObjectiveThe purpose of this study was to investigate the effect of 4 weeks of sling-based manual therapy on the cervicothoracic junction (CTJ) area in patients with neck pain and forward head posture.DesignSingle-blind randomized controlled trial.SettingOutpatient, Chonbuk National University hospital, Republic of Korea.SubjectsA total of 22 participants with neck pain (Numeric Pain Rating Scale >3) and forward head posture (craniovertebral angle <51) were randomly assigned to a CTJ group or a control group (n = 11 each).InterventionIn the control group, joint mobilization and motor control training was applied for the upper cervical spine (C0–C1). The CTJ group applied the same intervention to the upper cervical spine and cervicothoracic junction (C7-T3).Main measuresNumeric pain rating scale and neck disability index, craniovertebral angle, active range of motion, and muscle activity were evaluated before and after 4 weeks of intervention.ResultThe CTJ group participants showed significant improvement in the craniovertebral angle and cervical extension range after the intervention than the control group (P = 0.025, P = 0.001). While both groups presented significant differences after the intervention regarding Numeric pain rating scale, neck disability index, and muscle activity (sternocleidomastoid and anterior scalene muscle), there were no statistically significant differences between the groups (P > 0.05).ConclusionOur results suggest that the CTJ and the upper cervical region in patients with neck pain and forward head posture represent an area which if approached by manual therapy, improves cervical mobility and posture.     

Effects of the craniocervical flexion and isometric neck exercise compared in patients with chronic neck pain: A randomized controlled trial

ABSTRACT

Introduction: The present study compared the effects of neck isometric exercise (NIE) and craniocervical flexion exercise (CFE) on cervical lordosis, muscle endurance of cervical flexion, neck disability index (NDI), and active cervical range of motion (ACROM) in all three planes in patients with non-specific, chronic neck pain (CNP). Materials and Methods: Forty-one patients from a university hospital-based rehabilitation center were randomly assigned to an experimental (22 patients performing CFE) or control (19 patients performing NIE) group. All patients performed three 30-second repetitions of stretching exercises for the neck flexor, extensor, lateral flexor, and rotator as warm-up and cool-down exercises. The patients in the experimental group then underwent CFE 30 minutes/day, 3 times a week, for 8 weeks, while the control group underwent NIE. The main outcome measures were pain on visual analogue scale (VAS) and perceived disability based on the neck disability index (NDI). The secondary outcomes were cervical lordosis measured by an absolute rotation angle (ARA), muscle endurance of cervical flexion, and ACROM. Results: Both groups showed improved pain, NDI, endurance of the cervical flexor muscles, and ACROM in all three planes after 8 weeks (p < 0.001 for all). All these outcomes, except for the NDI, showed significantly greater improvements following CFE than following NIE (p < 0.05 for all). In particular, a significantly improved ARA of cervical lordosis was found following CFE but not following NIE (p < 0.05). Conclusions: CFE targeted at retraining the craniocervical flexor muscles was useful for improving or restoring the pain, cervical lordosis, and neck-related function disorders among patients with non-specific CNP.     

Effects of static stretching and strengthening exercises on flexion relaxation ratio in patients with LBP: A randomized clinical trial

IntroductionStretching and strengthening exercises are commonly used to improve muscle shortness. Consequently, the aim of this trial was to compare the flexion-relaxation response (electromyography activities of shortened hamstring and back muscles) in chronic nonspecific LBP patients.MethodsIn this randomized controlled clinical trial, forty-five eligible patients were randomly categorized into three groups; static stretching (n = 15), strengthening exercise in lengthened hamstring position (n = 15) and control (n = 15). All groups received conventional physical therapy for LBP and the two intervention groups received special exercise programs as well. Each group performed three treatment sessions for a week, a total of 12 sessions. The flexion-relaxation ratio (FRR) for knee and back muscles were assessed as the primary outcome measure. Pain and functional disability for participants were also assessed.ResultsThe results indicated non-significant differences between the three groups regarding the changes of FRR (mean between-group differences ranged over 0.69 to 39.1; p > 0.05), pain and disability (mean between-group differences ranged over 0.15 to 5.96; p > 0.05). Within-group analysis for each group, revealed statistically significant improvement in the patients' score of either pain (mean within-group differences ranged over −27.20 to −35.76; p < 0.001) or disability (mean within-group differences ranged over −16.17 to 24.95; p < 0.001) as secondary outcomes. In other words, the scores of pain and disability decreased in all treatment groups as compared to the baseline.ConclusionNeither static stretching nor strengthening exercises in lengthened hamstring position affected FRR more than the control group.     

Comparison of the effectiveness of proprioceptive neuromuscular facilitation exercises and shoulder mobilization patients with Subacromial Impingement Syndrome: A randomized clinical trial

IntroductionThe aim of this study was to compare the effectiveness of Proprioceptive Neuromuscular Facilitation (PNF) exercises and shoulder mobilization (SM) in addition to conventional physiotherapy on pain, range of motion (ROM), functionality, and muscle strength in patients with Subacromial Impingement Syndrome (SIS).MethodsForty-four patients were randomly allocated into three groups as conventional physiotherapy (control group; n = 14), conventional physiotherapy + PNF exercises (PNF group; n = 15), and conventional physiotherapy + SM techniques (SM group; n = 15). Pain, ROM, muscle strength, and functionality were evaluated by using VAS (Visual Analog Scale), goniometer, push-pull dynamometer, Constant-Murley score and DASH (Disabilities of the Arm, Shoulder and Hand) score. Patients were received 20 sessions (4 weeks) of treatment. Assessments were performed at baseline, and weeks two, four, and sixteen.ResultsAfter treatment, significant improvements in outcome measurements were observed in all groups (all p < 0.05). PNF or SM groups were not superior to each other in terms of improving pain and functionality. SM group was superior to PNF group for improving shoulder flexion ROM at week 4 (p = 0.009). The improvements in shoulder extension muscle strength were greater in PNF group at weeks 2 and 16 compared with other groups (p = 0.030, 0.035).ConclusionPNF or SM, in addition to conventional physiotherapy, might help to improve pain and functionality more in patients with SIS. It is recommended to add SM or PNF to conventional treatment to maintain the ROM increase gained with SIS treatment after treatment, and to apply this treatment for 4 weeks for muscle strength increase.     

Comparison of two mobilization techniques in management of chronic non-specific low back pain

AimThe aim of the study was to compare between the effects of Maitland's postero-anterior (PA glide) mobilization and Mulligan's sustained natural apophyseal glide (SNAG) on pain, mobility, muscle activation and functional disability in subjects with chronic, non-specific low back pain.MethodsThe study was a two arm repeated measure design with random allocation of subjects (n = 33). Subjects in group 1 received Maitland's PA glide mobilization and those in group 2 received Mulligan's SNAG. Along with the respective mobilization technique, individualized exercises were common for subjects in both the groups. Subjects in both groups received treatment for 4 days a week for 4 weeks. The outcome measures were numeric pain rating scale (NPRS) scores, lumbar flexion and extension range of motion, erector spinae muscle activity and Oswestry low back pain disability questionnaire score.ResultsThe outcome measure scores showed statistical significance in time effect on NPRS (p = 0.001); lumbar flexion and extension range of motion (p = 0.001); erector spinae muscle activity (0.001); Oswestry low back pain disability questionnaire score (p = 0.001); group effect on lumbar flexion (p = 0.03) and extension range of motion (p = 0.05); and interaction effect (time x group) on lumbar flexion (p = 0.003) and extension range of motion (p = 0.002); and, erector spinae muscle activity (p = 0.05) at the 3rd lumbar vertebral level.ConclusionThe addition of Maitland or Mulligan mobilization techniques of the spine does not show a difference in the improvement of symptoms associated with chronic non-specific low back pain.     

A preliminary study comparing the use of cervical/upper thoracic mobilization and manipulation for individuals with mechanical neck pain

Objectives:Neck pain is routinely managed using manual therapy (MT) to the cervical and thoracic spines. While both mobilizations and manipulations to these areas have been shown to reduce neck pain, increase cervical range of motion, and reduce disability, the most effective option remains elusive. The purpose of this preliminary trial was to compare the pragmatic use of cervical and thoracic mobilizations vs. manipulation for mechanical neck pain.Methods:This trial included 20 patients with mechanical neck pain. Each patient was randomized to receive either mobilization or manipulation to both the cervical and thoracic spines during their plan of care. Within-group analyses were made with Wilcoxon signed-rank tests and between-group analyses were made with Mann–Whitney U.Results:There were no between-group differences for any of the dependent variables including cervical active range of motion (CAROM) (P = 0.18), deep cervical flexion (DCF) endurance (P = 0.06), numerical pain rating scale (NPRS) (P = 0.26), the neck disability index (NDI, P = 0.33), patient-specific functional scale (PSFS, P = 0.20), or the global rating of change (GROC) scale (P = 0.94). Within-group results were significant for all outcome variables (P<0.001) from initial evaluation to discharge for both groups.Discussion:These findings were consistent with other trials previously conducted that applied the MT techniques in a pragmatic fashion, but varied from previous trials where the treatment was standardized. A larger experimental study is necessary to further examine the differences between mobilization and manipulation for neck pain.     

Correlation between baropodometric variables,disability, and intensity of low back pain in pregnant women in the third trimester

BackgroundGrowth of uterus, enlargement of breasts and weight gain result from the development and growth of the fetus during pregnancy. The posture and the displacement of the center of gravity change.ObjectiveCorrelate baropodometric variables with low back pain in pregnant women in the third trimester of pregnancy.MethodsThis is a cross-sectional analytical study conducted in São Luís (MA, Brazil). For data collection, we used a form containing sociodemographic and clinical data, Oswestry Disability Questionnaire for disability evaluation of the lumbar spine, Numerical Rating Scale to measure pain intensity, and baropodometric evaluation.ResultsTwenty-five pregnant women took part in the study. There was a significant and positive correlation (r = 0.404, p = 0.045) between functional disability and hindfoot pressure and a significant and negative correlation (r = −0.404, p = 0.045) between functional disability and plantar pressure in the forefoot of the right foot. In addition, there was a positive and significant correlation between the intensity of pain and the contact area on the left (r = 0.504, p = 0.010) and right (r = 0.509, p = 0.009) foot.ConclusionThere is a relation between disability and plantar pressure and between pain intensity and area of contact of feet in pregnant women.     

Effects of movement impairment based treatment in the management of mechanical neck pain

Background

Neck pain is a common musculoskeletal complaint in computer users due to prolonged static or awkward work postures. It has been shown that pathogenesis of neck pain is associated with scapular movement impairment syndromes. However, there is a dearth of literature in treatment based on these syndromes.

Origin of neck pain and direction of movement influence dynamic cervical joint motion and pressure pain sensitivity

BackgroundPatients with neck pain normally showed alterations in cervical motion and pressure pain sensitivity. Cervical joints show scattered motions opposite to (anti-directional) the primary motion direction (pro-directional) during dynamic cervical flexion and extension. This study aimed to assess dynamic cervical joint motion and pressure pain sensitivity when pain originated from different cervical muscles which may have clinical relevance in diagnosis of impairments related with neck pain.MethodsFluoroscopic video recordings of cervical flexion and extension were collected from fifteen healthy subjects before and during hypertonic saline-induced pain in right multifidus and trapezius muscles. Cervical flexion and extension motions were divided into 10 epochs with respect to time. Pro-directional, anti-directional, and total joint motion were extracted across epochs as well as joint motion variability. Pressure pain thresholds (PPTs) were assessed bilaterally over C2/C3 and C5/C6 facet joints.FindingsCompared with baseline: 1) Multifidus muscle pain increased the C3/C4 anti-directional motion (P < 0.01), decreased the C6/C7 anti-directional motion (P < 0.05) during extension, and redistributed total joint motion between joints and between half ranges during flexion (P < 0.05). 2) Trapezius muscle pain decreased pro-directional motion (P < 0.05), anti-directional motion (P < 0.05), and joint motion variability (P < 0.05) during extension. 3) Trapezius and multifidus muscle pain increased the PPTs bilaterally over C2/C3 and on the left side of C5/C6 facet joints (P < 0.05).InterpretationThe direction of motion influenced the effects of experimental muscle pain on dynamic cervical joint kinematics, and deep muscle pain showed local effects on individual joints while superficial muscle pain showed global effects spread to all joints.     

A comparison of mobilization and mobilization with movement on pain and range of motion in people with lateral ankle sprain: A randomized clinical trial

BackgroundMaitland and Mulligan mobilization techniques are two manual therapy methods to increase the range of motion following immobility treatment. The present study was conducted to compare two therapeutic methods, namely mobilization and mobilization with movement (MWM), on the pain and range of motion in people with lateral ankle sprain.MethodsA total of 40 individuals with grade two lateral ankle sprain were randomly divided into two groups, including the Maitland's mobilization intervention group, and the Mulligan's mobilization intervention group. Both groups underwent treatment every other day for two consecutive weeks. The pain intensity was measured using the Visual Analogue Scale (VAS), and the ankle dorsiflexion movement range using the Weight Bearing Lunge Test (WBLT) before and one day after the intervention.ResultsThere were no significant differences between the two groups in terms of pain (P = 0.297) and range of motion (P = 0.294) before the intervention. Meanwhile, after the intervention, a significant change was observed in both groups in terms of these variables, which indicates the effectiveness of both interventions (P < 0.001) and the greater effect of the mobilization with movement in reducing pain (P = 0.037) and increasing the range of motion (P = 0.021).ConclusionsBoth techniques significantly improved the range of motion and reduced pain in people with lateral ankle sprain, but Mulligan's technique was significantly more effective among the two, perhaps due to joining active and passive mobilizing tensile forces as well as interaction of afferents and efferents in the reflex arc.     

Pilates method for low back pain in individuals with Parkinson’s disease: A feasibility study

BackgroundPain is one of the most common and troublesome non-motor symptoms in Parkinson's disease (PD), including low back pain (LBP).ObjectiveThis study aims to evaluate the feasibility, acceptability, and safety of using Pilates for individuals with PD and LBP, as well as the effect on pain intensity, disability, motor and nonmotor PD symptoms, and quality of life. METHODS: Participants received 24 sessions of supervised Pilates twice a week for 12 weeks, each session consisting of 60 min. The isometric contractions of the core muscles were emphasized.ResultsFifteen (13%) of the screened patients were enrolled in the study and continued for the entire 2 months (100%). Participants completed the full training in 352 of 360 sessions (98%). Adverse effects were not reported. Pain and disability were significantly improved after intervention (Visual Analog Scale, p = 0.007; McGill Pain Questionnaire, p = 0.034; Roland-Morris Disability Questionnaire, p = 0.035). There were also significant improvements in depressive symptoms (Beck Depression Inventory, p = 0.028) and PD symptoms (Unified Parkinson's Disease Rating Scale – UPDRSI, UPDRSIII, UPDRS Total). However, there were no statistically significant changes in fatigue and quality of life.ConclusionsThis study suggests that the 12-week Pilates program is feasible and well tolerated by people with PD in mild to moderate stages of the disease. It also appears to be a promising strategy to reduce pain intensity and LBP-related disability, as well as PD motor and non-motor symptoms, which can be associated with this painful symptom. This study provides a basis for future investigations, especially randomized clinical trials.     

A comparison of two non-thrust mobilization techniques applied to the C7 segment in patients with restricted and painful cervical rotation

Objectives:

Cervical mobilization and manipulation have been shown to improve cervical range of motion and pain. Rotatory thrust manipulation applied to the lower cervical segments is associated with controversy and the potential for eliciting adverse reactions (AR). The purpose of this clinical trial was to describe two translatory non-thrust mobilization techniques and evaluate their effect on cervical pain, motion restriction, and whether any adverse effects were reported when applied to the C7 segment.

Methods:

This trial included 30 participants with painful and restricted cervical rotation. Participants were randomly assigned to receive one of the two mobilization techniques. Active cervical rotation and pain intensity measurements were recorded pre- and post-intervention. Within group comparisons were determined using the Wilcoxon signed-rank test and between group comparisons were analyzed using the Mann–Whitney U test. Significance was set at P = 0.05.

Results:

Thirty participants were evaluated immediately after one of the two mobilization techniques was applied. There was a statistically significant difference (improvement) for active cervical rotation after application of the C7 facet distraction technique for both right (P = 0.022) and left (P = 0.022) rotation. Statistically significant improvement was also found for the C7 facet gliding technique for both right (P = 0.022) and left rotation (P = 0.020). Pain reduction was statistically significant for both right and left rotation after application of both techniques. Both mobilization techniques produced similar positive effects and one was not statistically superior to the other.

Discussion:

A single application of both C7 mobilization techniques improved active cervical rotation, reduced perceived pain, and did not produce any AR in 30 patients with neck pain and movement limitation. These two non-thrust techniques may offer clinicians an additional safe and effective manual intervention for patients with limited and painful cervical rotation. A more robust experimental design is recommended to further examine these and similar cervical translatory mobilization techniques.     

Reduced flexion rotation test in women with chronic and episodic migraine

ObjectiveTo compare flexion rotation test and global active cervical mobility in women with chronic migraine, episodic migraine, and headache-free controls. The influence of neck pain-related disability on the flexion rotation test was also analyzed.MethodsWomen with chronic migraine (n = 25), episodic migraine (n = 30), and those who were headache-free (n = 30) were evaluated. Upper cervical mobility was measured using the flexion rotation test and global active mobility was assessed using the cervical range of motion device. Neck pain related-disability was assessed using the Neck Disability Index. Statistical analyses were performed using a MANOVA test, prevalence ratios, and linear regression.ResultsChronic (right, MD: ?15°; 95%CI: ?21° to ?11°; left, MD: ?13°; 95%CI: ?20° to ?12°) and episodic (right, MD: ?8°; 95%CI: ?13° to ?4°; left, MD: ?8°; 95%CI: ?12° to ?5°) migraine groups achieved lower flexion rotation test mobility bilaterally than headache-free women. Only chronic migraine was associated with a lower global cervical range of motion compared to that of headache-free women during flexion, (MD: ?8°; 95%CI: ?15° to ?1°), extension (MD: ?13°; 95%CI: ?20° to ?4°), right lateral flexion (MD: ?4°; 95%CI: ?9° to ?0.2°), left lateral flexion (MD: ?6°; 95%CI: ?10° to ?2°), right rotation (MD: ?9°; 95%CI: ?15° to ?4°), and left rotation (MD: ?8°; 95%CI: ?13° to ?2°). Migraine was associated with a 2.85-fold increase in the risk of a positive flexion rotation test. Flexion Rotation Test was influenced by disability-related neck pain (R² = 19.1; p = 0.001).ConclusionWomen with migraine have a lower upper cervical range of motion than headache-free women. Women with chronic migraine demonstrated reduced global cervical range of motion when compared to headache-free women. Migraine was associated with in increased likelihood of a positive Flexion Rotation Test. Reduction in mobility was influenced by migraine frequency and disability-related neck pain.     

Immediate Effects of a Single Session of Cervical Spine Manipulation on Cervical Movement Patterns in People With Nonspecific Neck Pain: A Randomized Controlled Trial

ObjectiveThe aim of the present study was to assess the immediate effects of a single session of cervical spine manipulation on cervical movement patterns, disability, and the patient's perceived improvement in people with nonspecific neck pain.MethodsA single-blinded, randomized, sham-controlled trial was carried out at a biomechanics institute. Fifty participants diagnosed with acute and chronic nonspecific neck pain (minimum duration of the symptoms being 1 month) were randomized to an experimental group (EG, n = 25) or a sham-control group (CG, n = 25, 23 of whom completed the study). EG received a single cervical spine manipulation session; CG received a single placebo intervention. Both groups received manipulation or sham from the same physiotherapist. Main outcome measures were neck kinematics (ie, range of motion and movement harmony) during cyclic movements, self-reported neck disability, and impression of change assessed before and 5 minutes after treatment.ResultsThe EG showed no significant improvements (P > .05) in any of the studied biomechanical variables, except for right-side bending and left rotation, in which we found a range of motion significant mean difference of 1.97° and 1.95°, respectively (P < .05). The CG showed enhanced harmonic motion during flexion (P < .05). Both groups showed a significant decrease in self-reported neck disability after treatment (P < .05), and EG participants perceived a significantly larger improvement after manipulation compared with the CG (P < .05).ConclusionsA single session of cervical manipulation provided by a physiotherapist had no impact on cervical motion during cyclic movements, but rather induced self-reported perceived improvement in neck disability and impression of change after treatment in people with nonspecific neck pain.     

Effectiveness of Scapular Stabilization Versus Non-Stabilization Stretching on Shoulder Range of Motion,a Randomized Clinical Trial

BackgroundPrevious research has demonstrated the benefits of both stabilization and non-stabilization of the scapula during stretching in individuals with posterior shoulder tightness, but limited evidence exists in patients with shoulder pain.Hypothesis/PurposeThe aim of this study was to determine the effect of stabilized scapular stretching on patients with shoulder pain. The primary hypothesis of this study is that stabilized scapular stretching will improve glenohumeral motion and pain compared to non-stabilized stretch program. A secondary hypothesis of this study is that stabilized scapular stretching will produce greater improvement in function compared to the non-stabilized stretching program.Study DesignRandomized Clinical TrialMethodsSixteen patients with sub-acromial pain associated with tendinopathy and associated pathologies presenting to physical therapy were randomized into two groups (stabilized or non-stabilized scapular stretching). Baseline pain and range of motion were measured prior to and following each treatment session for three visits that occurred over the course five to seventeen days depending on the patients availability. The dependent measurements were stabilized horizontal adduction, stabilized internal rotation, stabilized shoulder flexion, non-stabilized shoulder flexion, and current pain level.ResultsPatients in the scapular stabilization stretching group increased horizontal adduction 40° (CI₉₅ 31, 48°) compared to the non-stabilization stretching group increase of 8° (CI₉₅ 0, 17°) over the course of the three treatments (p<0.001). Similarly, the stabilized stretching group increased internal rotation 48° (CI₉₅ 26, 69°) compared to the non-stabilized stretching group increase of 26° (CI₉₅ 4, 48°) (p=0.001). Pain decreased in the stabilized stretching group by 1.4 points (CI₉₅ -0.4, 3.2) but increased slightly in non-stabilized group by -0.5 points (CI₉₅ -2.3, 1.3) which was not a clinically meaningful change. (p=0.03)ConclusionStabilized scapular stretching was more effective than non-stabilized stretching at gaining shoulder mobility in patients with shoulder pain. Benefits were immediate and sustained between treatment sessions. Stretching interventions improved range of motion but had limited effect on shoulder pain.Level of Evidence2
