To evaluate Ultrasound Imaging (USI) reliability for measurement of lumbar multifidus (LMF) muscle thickness and cross sectional area (CSA) at rest and during contraction in patients with unilateral lumbar disc herniation.
Laboratory.
Reliability Study.
Thirty patients, aged 25-50 years (37.55 ± 9.55), with unilateral L4-L5 lumbar disc herniation participated in this study.
Thickness and CSA of LMF were measured using B-mode ultrasound by two raters in prone position.
Same day and multiple day inter-rater and same day intra-rater reliability showed good to excellent reliability (intraclass correlation coefficients ranged from 0.70 to 0.91). Also standard error of measurement and minimal detectable change for USI reliabilities ranged from 0.06 to 0.57 and 0.16 to 1.31, respectively.
Reliability of USI for measurements of LMF muscle thickness and CSA was high, and consistent with previous studies conducted on reliability of USI to measure LMF dimensions in other populations.

Decrease in cross-sectional thickness of lumbar multifidus (MF) muscles during prolonged low back pain episodes commonly occurs. Restoration of the MF muscle size can be an effective way of treating chronic low back pain (CLBP) patients. Traditionally, clinicians apply muscle stabilization exercises for these patients. Recent studies support the need for active strengthening exercises for treatment of the CLBP patients.
The MF muscles provide lumbar stability, and therefore we hypothesized that strengthening of these muscles can be more effective than the MF muscle stabilization exercises in restoration of the muscle size.
Study design was a randomized allocation control trial with two groups of adult female CLBP patients (n=12 each; age range of 20-45). Patients in the control group underwent stabilization exercises and the patients in the intervention group underwent the hip abductor strengthening exercises.
For all subjects of each group, the trials continued in 24 sessions distributed over 8 weeksses for effective treatment of female adults with CLBP is recommended.
To describe a conservative approach to care of an adult patient presenting with chronic abdominal wall pain persisting two years following abdominal surgery.
A 62-year-old female presented to a chiropractic neurologist with abdominal wall pain and sensation deficits. Her prior surgical history and a positive Carnett's sign indicated anterior cutaneous nerve entrapment syndrome (ACNES).
Treatments, including manual therapy, rehabilitation, and desensitization techniques, significantly reduced the frequency and severity of the ACNES symptoms.
ACNES can be effectively managed via nonsurgical and non-pharmacological treatment methods.

Individuals with shoulder and upper extremity pathology often present with altered scapular motion. Few studies have looked at variations in scapular acceleration as a way of quantifying scapular motion. The purpose was to determine the effectiveness of wireless accelerometers for detecting changes in acceleration in individuals with scapular dyskinesis.
Twenty-seven asymptomatic college students (mean age 24 (SD±1.54), 65% female, 93% right handed) were visually screened for scapular dyskinesis using previously described criteria. Of the students recruited, fifteen students were determined to have scapular dyskinesis. After securing a wireless accelerometer (MyoResearch 3D DTS) on the dominate scapula, the participants performed five repetitions of standing scaption from 0 to 140°. Linear scapular accelerations along three orthogonal axes (frontal-y, transverse-z, and sagittal-x) were collected. Intraclass correlation coefficients (ICC
) were used to determine the between day intra-rater reliability whiroup without dyskinesis.
The purpose of the cross-sectional observational cohort study was to quantify movement patterns and neuromuscular impairments in Olympic Female Field Hockey utilizing a standardized movement-centered assessment model.
A sample of convenience was obtained from the active roster of the 2016 USA Women's Olympic Field Hockey team. Inclusion and exclusion criteria were applied and resulted in nine participants. The study was conducted over 1 session in which each athlete was tested using the SFMA™, Y Balance Test Lower Quarter (YBT-LQ™) FMS™, and closed chain dorsiflexion range of motion (CKCDFROM). XYL-1 clinical trial Injury risk assignment was generated based on an evidenced based algorithm. Descriptive statistics and frequency distributions were applied to the subjects.
Injury risk stratification was applied to the subjects with 44% being at moderate risk and 56% at slight risk. 100% of the athletes exhibited spinal extension deficits and 89% of the athletes displayed a dysfunctional single leg stance pattern. Regional impaiinjury risk for the spine and lower quarter.
Functional dry needling (FDN) is commonly used to treat soft tissue pain-related conditions. Previous research has demonstrated benefits to chronic resistance training; however, objective physiological measures sensitive to acute exercise have not been found. The purpose of this study was to evaluate the acute effects of FDN on muscle strength and endurance.
Ten subjects (height 168±9cm, mass 68.2±11.3kg) were tested bilaterally (pre and post) for vastus lateralis (VL) isometric strength, isokinetic fatigue index, muscle electrical activity, and muscle oxygenation. FDN was administered to one leg, while the other served as a control.
Limited acute effects of functional dry needling were observed (p<0.05).
FDN does not appear to acutely improve muscle function in healthy young adults. Although there were no improvements in muscle function, there were no adverse effects either, contributing to the safety of FDN healthy populations.
Acute FDN does not appear to enhance muscle performance in a healthy, non-clinical population.XYL-1 clinical trial
