Changes in proprioception and pain in patients with neck pain after upper thoracic manipulation

Effectiveness and safety of thoracic manipulation in the treatment of neck pain: An updated systematic review and meta-analysis

BACKGROUND

The purpose of this meta-analysis was to evaluate the effectiveness and safety of thoracic manipulation (TM) in patients with neck pain (NP).

OBJECTIVE

The purpose of this meta-analysis was to evaluate the effectiveness and safety of thoracic manipulation (TM) in patients with neck pain (NP).

METHODS

Seven electronic databases were searched from their inception through October 2023 by two authors. The methodological quality assessments were performed with the Physiotherapy Evidence Database (PEDro) scale. Pain, cervical range of motion (ROM), disability, and quality of life (QOL) were estimated for TM treatment in patients with NP.

RESULTS

Eighteen randomized controlled trials (RCTs) with 914 patients were included with a PEDro score of 6.923 ± 3.120. Pooled effect sizes of pain (SMD =-0.481, 95% CI -0.653 to -0.309, P= 0.000), disability (SMD =-1.435, 95% CI -2.480 to -0.390, P= 0.007), QOL-physical component score (PCS) (SMD = 0.658, 95% CI 0.290 to 1.025, P= 0.000), ROM of flexion (SMD = 0.921, 95% CI 0.287 to 1.555, P= 0.000), ROM of extension (SMD = 0.572, 95% CI 0.321 to 0.822, P= 0.000), ROM of left lateral flexion (SMD = 0.593, 95% CI 0.075 to 1.112, P= 0.025) and ROM of left rotation (SMD = 0.230, 95% CI 0.010 to 0.450, P= 0.04) were favored by the TM group.

CONCLUSIONS

TM provides short-term effect on relieving neck pain, increasing cervical ROM, and disability in patients with NP without serious side effects. Continuous therapy and distraction therapy are recommended as optimal choice on reducing pain and improving cervical ROM, especially in patients with chronic NP (> 3 months). The TM-induced improvements in the QOL of patients with NP should be verified by more further high-quality RCTs.

Effectiveness of Thoracic Spine Manipulation on the Management of Neck Pain: A Systematic Review and Meta-Analysis of Randomized Control Trials

There are contradicting findings regarding the effect of thoracic spine manipulation in decreasing pain and disability in patients with chronic mechanical neck pain. Hence, the purpose of this review was to evaluate the current evidence on the effectiveness of thoracic spine thrust manipulation in decreasing pain intensity, and neck disability among subjects with chronic mechanical neck pain. We made a comprehensive search of literature published between 2010 and 2020 from the electronic databases of PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, and Physiotherapy Evidence Database (PEDro). We adhered to Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA). The methodological quality was assessed by the PEDro scale, and the level of evidence rated by Grading of Recommendations Assessment, Development, and Evaluation (GRADE) software. Finally, a meta-analysis was done using RevMan 5.3 with a random-effects model to calculate the mean difference (MD) and 95% confidence intervals for pain and disability. Eight eligible randomized controlled trials were identified with a total of 457 participants. The quality assessment of the included studies was found to be fair in quality (mean PEDro score of 6.63/10). The overall GRADE of the review showed low to moderate level of evidence. Effect size estimates of the studies showed modest differences in pain reduction, as it revealed a significant effect in Visual Analog Scale ((VAS) 0-100mm) (MD -12.46; 95% CI: -17.29, -7.64), and Pain Numeric Rating Scale ((PNRS) 0-10 pts) (MD -0.8; 95% CI: -1.60, -0.10). The thoracic manipulation also resulted in a significant effect in decreasing neck disability, in which the mean difference in Neck disability index (NDI) showed (MD -6.46; 95% CI: -10.43 -2.50). This review suggested that thoracic spine manipulation was effective in reducing pain and neck disability in all adults with chronic mechanical neck pain compared to other interventions.

Influence of Neck Pain, Cervical Extensor Muscle Fatigue, and Manual Therapy on Wrist Proprioception

OBJECTIVE

The purpose of this study was to examine the effects of submaximal isometric neck muscle fatigue and manual therapy on wrist joint position sense (JPS) within healthy individuals and individuals with subclinical neck pain (SCNP).

METHODS

Twelve healthy participants and 12 participants with SCNP were recruited. Each group completed 2 sessions, with 48 hours between sessions. On day 1, both groups performed 2 wrist JPS tests using a robotic device. The tests were separated by a submaximal isometric fatigue protocol for the cervical extensor muscles (CEM). On day 2, both groups performed a wrist JPS test, followed by a cervical treatment consisting of manual therapy (SCNP) or neck rest (20 minutes, control group) and another wrist JPS test. Joint position sense was measured as the participant's ability to recreate a previously presented wrist angle. Each wrist JPS test included 12 targets, 6 into wrist flexion and 6 into wrist extension. Kinematic data from the robot established absolute, variability, and constant error.

RESULTS

Absolute error significantly decreased (P = .01) from baseline to post-fatigue in the SCNP group (baseline = 4.48 ± 1.58°; post-fatigue = 3.90 ± 1.45°) and increased in the control group (baseline = 3.12 ± 0.98°; post-fatigue = 3.81 ± 0.90°). The single session of manual cervical treatment significantly decreased absolute error in participants with SCNP (P = .004).

CONCLUSION

This study demonstrated that neck pain or fatigue can lead to altered afferent input to the central nervous system and can affect wrist JPS. Our findings demonstrate that acute wrist proprioception may be improved in individuals with SCNP by a single cervical manual therapy session.

A Single-Center Study Comparing the Effects of Thoracic Spine Manipulation vs Mobility Exercises in 26 Office Workers with Chronic Neck Pain: A Randomized Controlled Clinical Study

Background

Neck pain is associated with computer work, poor posture, imbalanced neck muscles, and fatigue, particularly in office workers. This study from a single center aimed to compare the effects of thoracic spine mobility exercise and thoracic spine manipulation to improve cervical spine range of motion in 26 office workers who had chronic neck pain for more than 12 weeks.

Material/Methods

The participants were 26 office workers with neck pain lasting >12 weeks. These participants were randomly assigned to undergo TSME (n=13) or TSM (n=13). Both groups underwent cervical joint mobilization and deep cervical flexor muscle exercises for 25 min a day, twice weekly, for 6 weeks. The TSME group additionally performed TSME 15 min a day, twice a week, for 6 weeks, while the TSM group received TSM 2 times a day, twice a week, for 6 weeks. Cervical and thoracic spine ROM, numeric pain rating scale (NPRS), and neck disability index (NDI) were measured before and after interventions. The ROM of cervical and thoracic spine was measured using a dual inclinometer.

Results

Both groups showed significant changes in cervical spine ROM, thoracic spine ROM, NPRS, and NDI after intervention compared to before intervention (P<0.05). Cervical spine right lateral flexion and right rotation differed significantly between the groups (P<0.05), while thoracic spine ROM, NPRS, and NDI did not.

Conclusions

TSME and TSM have similar effects in improving pain and disability in office workers with non-specific chronic neck pain.

Immediate effects of thoracic manipulation on cervical joint position sense in individuals with mechanical neck pain: A randomized controlled trial

BACKGROUND

Performing thoracic manipulations for neck pain can result in immediate improvements in neck function.

OBJECTIVE

The aim of this study was to investigate the immediate effects of thoracic manipulation on cervical joint position sense and cervical range of motion in individuals with chronic mechanical neck pain.

METHODS

Eighty male volunteers between 18-25 years and having chronic or recurrent neck or shoulder pain of at least 3 months duration with or without arm pain were randomized into two groups: Thoracic Manipulation Group (TMG:50) and Control Group (CG:30), with a pretest-posttest experimental design. The TMG was treated with thoracic extension manipulation while the CG received no intervention. Cervical joint position error and cervical range of motion of the individuals were assessed at baseline and 5 minutes later.

RESULTS

There was no difference in demographic variables such as age (p= 0.764), Body Mass Index (p= 0.917) and Neck Pain Disability Scale (NPDS) scores (p= 0.436) at baseline outcomes between TMG and CGs. Joint position error outcomes between the two groups following intervention were similar in all directions at 30 and 50 degrees. Differences in range of motion following intervention in neck flexion (p< 0.001) and right rotation (p= 0.004) were higher in TMG compared to CG.

CONCLUSIONS

A single session of thoracic manipulation seems to be inefficient on joint position sense in individuals with mild mechanical neck pain. However, thoracic manipulation might be an effective option to increase flexion and rotation of the cervical region as an adjunctive to treatment.

Postural Stability in Individuals with and without Sacroiliac Joint Dysfunction Before and After Pelvic Belt Application

Background: Sacroiliac Joint Dysfunction (SIJD) is considered an origin of low-back pain. It can change the motor control strategy and postural control (PC). Objectives: We aimed to find any probable differences in PC between subjects with and without SIJD and determine the effects of the pelvic belt (PB) on PC. Methods: Thirty-eight subjects were assigned into two equal groups with and without SIJD. They started to walk from the place marked on a force plate for 10 seconds after hearing an auditory signal and performed three attempts for each foot. They repeated six more ones with PB. Raw data were imported to an excel software (version 2007) spreadsheet to calculate the reaction time (RT) and anticipatory postural adjustment (APA) as the components of PC. Results: Our results showed a significant difference in RT between the SIJD-affected and non-affected sides (P = 0.035), but there was no significant difference in APA (P = 0.057). There were significant differences in RT and APAs between the control and SIJD-affected side groups (P = 0.001 and P = 0.010, respectively). The PB application showed a significant difference in RT and APAs of the SIJD-affected side (P = 0.001 and P = 0.047, respectively). Conclusions: It seems pain could lead to the postural sway into instability and change the motor control strategy. The proprioception signals from the neuromuscular system of SIJ improved after PB. Therefore, PB, as a feasible tool, can be recommended for PC improvement.

Wireless Motion Sensors-Useful in Assessing the Effectiveness of Physiotherapeutic Methods Used in Patients with Knee Osteoarthritis-Preliminary Report

Osteoarthritis of the knee (OAK) is characterized by pain, limitation of joint mobility, and significant deterioration of proprioception resulting in functional decline. This study assessed proprioception in OAK patients following two ten-day rehabilitation programs using the Orthyo® system. Fifty-four study participants with clinical symptoms and radiological signs of OAK were randomly divided into an exercise group (n = 27) or a manual therapy group (n = 27). The control group consisted of 27 volunteers with radiological signs of OAK, but with no clinical symptoms or prior history of rehabilitation. The following parameters were assessed: knee proprioception using inertial sensors and a mobile application, patients' function using Western Ontario and McMaster Universities osteoarthritis index (WOMAC), and pain intensity using the visual analog scale (VAS). Following rehabilitation, knee proprioception tests did not improve in either study group. Both study groups showed significant improvement of the WOMAC-assessed function (exercise group: p < 0.01, manual therapy group: p = 0.01) and a significant decrease (p < 0.01) of VAS-assessed pain following rehabilitation, but the post-therapy results did not differ significantly between the aforementioned groups. The Orthyo® system provided a quick and accurate assessment of the knee joint position sense. There was no direct relationship between functionality, pain, and proprioception threshold in the knee joint.

Completeness of the description of manipulation and mobilisation techniques in randomized controlled trials in neck pain; A review using the TiDieR checklist

STUDY DESIGN

A secondary analysis of a systematic review.

BACKGROUND

Manipulations or mobilizations are commonly used interventions in patients with mechanical neck pain. The treatment effects have often been studied in randomized controlled trials (RCT) which are generally considered the gold standard in evaluating the treatment effects, mainly due to its high internal validity. External validity is defined as the extent to which the effects can be generalised to clinical practice. An important prerequisite for this is that interventions used in clinical trials can be replicated in clinical practice. It can be questioned if interventions utilized in randomized controlled trials can be translated into clinical practice.

OBJECTIVES

The overall aim of this study is to examine whether the quality of the description of manipulation and mobilization interventions is sufficient for to replication of these interventions in clinical practice.

METHODS

A comprehensive literature search was performed. Two independent researchers used the Template for Intervention Description and Replication (TIDieR) which is a 12-item checklist for describing the completeness of the interventions.

RESULTS

Sixty-seven articles were included that used manipulation and/or mobilization interventions for patients with mechanical neck pain. None of the articles describe the intervention e.g. all the items on the TIDieR list. Considering item 8 (a-f) of the TIDieR checklist only one article described the used techniques completely.

CONCLUSION

Manipulation or a mobilization interventions are poorly reported in RCTs, which jeopardize the external validity of RCTs, making it difficult for clinicians and researchers to replicate these interventions.

Effects of kinesiotape on pain and disability in individuals with chronic low back pain: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE:

To explore the effects of kinesiotape on pain and disability in individuals with chronic low back pain.

DATA SOURCES:

PubMed, Embase and the Cochrane Central Register of Controlled Trials were searched for English language publications from inception to 13 February 2018.

REVIEW METHODS:

This study was registered in PROSPERO (CRD42018089831). Our key search terms were ((kinesio taping) OR (kinesiotaping) OR (kinesiotape)) AND (low back pain). Randomized controlled trials evaluating the effects of kinesiotape published in English language were included in this review. The reference lists of retrieved studies and relevant reviews were also searched. Quality of the included trials was assessed according to 2015 updated Cochrane Back and Neck Review Group 13-Item criteria.

RESULTS:

A total of 10 articles were included in this meta-analysis. A total of 627 participants were involved, with 317 in the kinesiotape group and 310 in the control group. The effects of kinesiotape on pain and disability were explored. While kinesiotape was not superior to placebo taping in pain reduction, either alone ( P = 0.07) or in conjunction with physical therapy ( P = 0.08), it could significantly improve disability when compared to the placebo taping ( P < 0.05).

CONCLUSION:

Since kinesiotape is convenient for application, it could be used for individuals with chronic low back pain in some cases, especially when the patients could not get other physical therapy.

The clinical reasoning process in randomized clinical trials with patients with non-specific neck pain is incomplete: A systematic review

OBJECTIVE

Primarily to evaluate the completeness of the description of the clinical reasoning process in RCTs with patients with non-specific neck pain with an argued or diagnosed cause i.e. an impairment or activity limitation. Secondly, to determine the association between the completeness of the clinical reasoning process and the degree of risk of bias.

DATA SOURCES

Pubmed, Cinahl and PEDro were systematically searched from inception to July 2016.

STUDY SELECTION

RCTs (n = 122) with patients with non-specific neck pain receiving physiotherapy treatment published in English were included.

DATA EXTRACTION

Data extraction included study characteristics and important features of the clinical reasoning process based on the Hypothesis-Oriented Algorithm for Clinicians II (HOAC II)].

DATA SYNTHESIS

Thirty-seven studies (30%) had a complete clinical reasoning process of which 8 (6%) had a 'diagnosed cause' and 29 (24%) had an 'argued cause'. The Spearmans rho association between the extent of the clinical reasoning process and the risk of bias was -0.2.

CONCLUSIONS

In the majority of studies (70%) the described clinical reasoning process was incomplete. A very small proportion (6%) had a 'diagnosed cause'. Therefore, a better methodological quality does not necessarily imply a better described clinical reasoning process.

Manual therapy, exercise therapy or combined treatment in the management of adult neck pain - A systematic review and meta-analysis

BACKGROUND

Neck pain is a common and often disabling musculoskeletal condition. Two therapies frequently prescribed for its management are manual therapy (MT) and exercise therapy (ET), and combining these treatment approaches are common.

OBJECTIVE

To assess whether or not combined treatment consisting of MT and ET is more effective than either therapy alone in relieving pain and improving function in adult patients with grade I-II neck pain.

DESIGN

Systematic review with meta-analysis.

METHODS

A systematic search on EMBASE, MEDLINE, AMED, CENTRAL and PEDro were performed until June 2017. Randomized controlled trials with adult grade I-II neck pain patients were included if they investigated the combined effect of MT and ET to the same ET or MT alone, and reported pain intensity or disability on numerical scales. Quality of life was assessed as a secondary outcome. Quality of the included trials was assessed with the PEDro scale, and the quality of evidence was assessed with GRADE.

RESULTS

1169 articles were screened, and 7 studies were included, all of which investigated the addition of ET to MT. Only very small and non-significant between group differences was found on pain intensity at rest, neck disability, and quality of life at immediate post-treatment, 6 months, and 12 months follow-up. The quality of evidence was moderate for pain-at-rest outcomes and moderate too low for neck disability and quality of life outcomes.

CONCLUSION

Combined treatment consisting of MT and ET does not seem to be more effective in reducing neck pain intensity at rest, neck disability or improving quality of life in adult patients with grade I-II neck pain, than ET alone.

Predictive factors for reporting adverse events following spinal manipulation in randomized clinical trials - secondary analysis of a systematic review

While spinal manipulative therapy (SMT) is recommended for the treatment of spinal disorders, concerns exist about adverse events associated with the intervention. Adequate reporting of adverse events in clinical trials would allow for more accurate estimations of incidence statistics through meta-analysis. However, it is not currently known if there are factors influencing adverse events reporting following SMT in randomized clinical trials (RCTs). Thus our objective was to investigate predictive factors for the reporting of adverse events in published RCTs involving SMT. The Physiotherapy Evidence Database (PEDro) and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for RCTs involving SMT. Domains of interest included: sample size; publication date relative to the 2010 CONSORT statement; risk of bias; the region treated; and number of intervention sessions. 7398 records were identified, of which 368 articles were eligible for inclusion. A total of 140 (38.0%) articles reported on adverse events. Articles were more likely to report on adverse events if they possessed larger sample sizes, were published after the 2010 CONSORT statement, had a low risk of bias and involved multiple intervention sessions. The region treated was not a significant predictor for reporting on adverse events. Predictors for reporting on adverse events included larger sample size, publication after the 2010 CONSORT statement, low risk of bias and trials involving multiple intervention sessions. We recommend that researchers focus on developing robust methodologies and participant follow-up regimens for RCTs involving SMT.

Effect of thoracic manipulation and deep craniocervical flexor training on pain, mobility, strength, and disability of the neck of patients with chronic nonspecific neck pain: a randomized clinical trial

[Purpose] To investigate the effects of thoracic manipulation and deep craniocervical flexor training on the muscle strength and endurance, range of motion, and the disability index of the neck of patients with chronic nonspecific neck pain. [Subjects and Methods] Forty-six patients with chronic neck pain participated. They received an intervention for 35 minutes a day, three times a week for 10 weeks. Subjects were randomly assigned to one control and two experimental groups: group A (thoracic manipulation combined with deep craniocervical flexor training, n=16), group B (deep craniocervical flexor training, n=15), and group C (active self-exercise as a control group, n=15). Muscle strength and endurance, pain, neck disability index, and range of motion of the cervical and thoracic spine were measured before and after the intervention. [Results] Group A showed significant increases in muscle strength, endurance, and cervical and thoracic range of motion, and significant decreases in the pain and neck disability index, compared with groups B and C. [Conclusion] Although deep craniocervical flexor training is effective at improving neck function, thoracic manipulation combined with deep craniocervical flexor training was a more effective intervention for pain relief and improving the range of motion, muscle function, and neck disability of patients with nonspecific chronic neck pain.
