Clinical effectiveness of the activator adjusting instrument in the management of musculoskeletal disorders: a systematic review of the literature

Objective:

The purpose of this study was to conduct a systematic review of the literature investigating clinical outcomes involving the use of the Activator Adjusting Instrument (AAI) or Activator Methods Chiropractic Technique (AMCT).

Methods:

A literature synthesis was performed on the available research and electronic databases, along with hand-searching of journals and reference tracking for any studies that investigated the AAI in terms of clinical effectiveness. Studies that met the inclusion criteria were evaluated using an instrument that assessed their methodological quality.

Results:

Eight articles met the inclusion criteria. Overall, the AAI provided comparable clinically meaningful benefits to patients when compared to high-velocity, low-amplitude (HVLA) manual manipulation or trigger point therapy for patients with acute and chronic spinal pain, temporomandibular joint (TMJ) dysfunction and trigger points of the trapezius muscles.

Conclusion:

This systematic review of 8 clinical trials involving the use of the AAI found reported benefits to patients with a spinal pain and trigger points, although the clinical trials reviewed suffered from many methodological limitations, including small sample size, relatively brief follow-up period and lack of control or sham treatment groups.     

ACTIVLIM: adaptación transcultural al castellano y validación en adultos con miopatías hereditarias utilizando el modelo Rasch

IntroductionACTIVLIM is an instrument for the measurement of activity limitations in patients with neuromuscular disorders. The aim of this study is to establish a transcultural adaptation and psychometric validation of the Spanish-language version of ACTIVLIM in a sample of Spanish patients with inherited myopathies.Patients and methodA Spanish-language version of ACTIVLIM was developed using the translation/back translation method. The questionnaire was administered to 135 patients with inherited myopathies. The psychometric properties of the questionnaire were assessed using the Rasch model. Floor and ceiling effects were estimated. Unidimensionality was evaluated with a principal component analysis of the residuals of the model, and using infit and outfit statistics. We estimated reliability with the person separation reliability index and invariance with differential item functioning. External construct validity was tested through correlation with the Brooke scale, the Vignos scale, the Functional Independence Measure scale, and floor-to-stand time. Test-retest reliability was evaluated with the intraclass correlation coefficient and differential item functioning.ResultsThe psychometric analysis of the Spanish-language version of ACTIVLIM demonstrated that floor effect was absent, although a modest ceiling effect was identified. The instrument displayed unidimensionality, good internal consistency, external construct validity, and good test-retest reliability.ConclusionThe Spanish-language version of ACTIVLIM is a valid and reliable measurement nstrument for assessing activity limitations in patients with inherited myopathies.     

口腔手术显微镜联合超声技术在根管再治疗中的应用效果

 目的 探讨口腔手术显微镜联合超声技术在根管再治疗中的应用效果,为根管治疗失败的预防和再治疗提供依据。方法 选择2017-07至2020-12在武警特色医学中心口腔科接受显微根管再治疗病例98例,98颗患牙(共计142个根管),记录根管治疗失败的原因,在口腔手术显微镜下使用超声器械对患牙进行根管再治疗,6个月后随访,统计成功率。结果 98颗患牙中78颗治疗成功,总体成功率79.6%。根管遗漏患牙的成功率为92.9%(13/14);根管钙化患牙的成功率为65.4%(17/26);器械分离患牙的成功率为75.0%(12/16);髓腔穿孔患牙的成功率为85.0%(17/20);根尖敞开患牙的成功率为100%(10/10);根管台阶患牙的成功率为75.0%(9/12)。结论 口腔手术显微镜联合超声技术在根管再治疗中的应用效果好,治疗成功率高。     

Parental affectionless control and suicidality

Objective

Although poor parental bonding is a known risk factor for suicidality, current literature is inconsistent about the relative role of low parental care and parental overprotection, as well as the combination of the two, termed “affectionless control”. This review presents the current state of knowledge of the relationship between suicidality and these two aspects of parental bonding.

Method

The computerized databases Medline, PubMed, PsychINFO, PsychLit, and Google Scholar were searched using combinations of the following keywords: suicidality, suicide, suicide attempt, suicidal behavior, parental bonding, and parental bonding instrument. Using the results, we reviewed the reports on the relationship between suicidality and parental bonding as measured by validated parental bonding instruments.

Results

Twelve papers were analyzed. All of them used the parental bonding instrument (PBI) and one used both the PBI and the object representation inventory (ORI). Most reports agreed that, in mothers, either lack of maternal care and/or overprotection was associated with an increase in suicidal behavior, while in fathers only low care was consistently associated with suicidality. This lack of constancy with regard to the effect of paternal overprotection appears to be due to cultural differences in fathers' role in child rearing. With these differences acknowledged, affectionless control in both parents emerges as the parenting style most strongly associated with suicidal behavior. Common methodological problems included low numbers of subjects, inconsistent control groups, and the lack of a uniform definition of suicidality.

Conclusion

Despite methodological limitations, current literature consistently indicates that parental affectionless control is associated with suicidal behavior. Recognizing affectionless control as a risk factor for suicide and developing early interventions aimed at modifying affectionless and overprotective parenting style in families with a history of affective disorders may be effective in reducing suicidal risk.
