Clinicians frequently assess movement performance during a trunk rotation task to observe
19 biomechanical deficits. The degeneration of the sensory (Brumagne et al., 2004) and motor systems (Horak et
20 al., 1989) is inevitable as age increases; thereby altered movement and/or postural control in older adults is
21 apparent.(Pyykko et al., 1990) For example, compared to younger adults, older adults show less rotational
22 ROM of the cervical spine (Trott et al., 1996) and of the thoracic spine (Baird and Van Emmerik, 2009) during
23 axial trunk rotation while standing as well as in sitting (Doriot and Wang, 2006). A comprehensive
24 investigation on different directions of rotation is required since trunk asymmetry exists during daily activities.

Such differences have the potential to contribute to variations in the kinematics and
39 shoulder-pelvic coordination in older adults with recurrent LBP.
40 In our study, the RP was defined by the kinematic differences between the angle of the shoulder and
41 pelvis during two phases of trunk rotation. The coordinated rotation of RP was investigated during rotation
42 from the left to the right side (RP1) as well as during the return phase to the left side (RP2). In addition, the
43 shoulder and pelvis ROM during trunk rotation was also investigated while considering individual
44 characteristics, such as age and BMI. Therefore, the purpose of this study was to compare changes in
45 kinematic differences of angular displacements with shoulder and pelvis ROM as well as RP based on trunk
46 coordination in different directions of rotation in older adults with and without recurrent LBP.

A VAS for pain intensity provides a quantitative measure of subjective pain and a total functional
68 disability score ranging from 0 to 100 mm.(Huskisson, 1983) The pain was generally rated during the
69 individual’s daily activities.
70 As indicated in Figure 1, in order to capture the angular displacement of trunk rotation, reflective
71 markers were attached to the bilateral shoulders, the first thoracic spine (T1), the 10th thoracic spine (T10), the
72 first sacrum (S1), and the bilateral posterior superior iliac spines (PSIS). Six digital cameras captured the
73 motion of each marker three-dimensionally (Motion Analysis Corporation, Santa Rosa, CA, USA). The signals
74 from the marker trajectories were filtered with a fourth-order zero-phase Butterworth low-pass filter with a
75 cutoff frequency of 6 Hz to eliminate noise from the raw data with the sampling rate at 100 Hz. The captured
76 data was recorded in a personal computer and further analyzed by customized software in MATLAB (The

Knee chest is a specific upper cervical technique used by many upper cervical chiropractors. It is an articular based model that allows correction of subluxation by hand. According to Craniocervical Chiropractic Procedures – A Precis of Upper Cervical Chiropractic (2015), the knee chest technique relies heavily on thermography to establish a pattern for the patient. In addition, a rest period post-adjustment is advocated. A typical knee chest adjustment begins with the doctor positioned in a fencer stance on the side of the listing. The patient is placed in a knee chest position with the upper cervical spine resting on the floating neck of the table and the patient’s head rotated towards the listing side. The doctor’s pisiform is the contact point and the segmental contact point is either the body, lamina pedicle junction, and lateral inferior portion of the axis spinous process or the posterior arch of atlas. The practitioner may also utilize a tissue pull. A base posterior film is imperative to determine the line of correction needed for the appropriate line of drive. Lastly, to execute the knee chest adjustment, the doctor may utilize a body drop and triceps extension perpendicular to the table
For shoulder flexion 61% of the variance could be accounted for by the sit-and-reach. A correlation was also found between the modified sit-and-reach test and both the shoulder extension and hip flexion tests. For shoulder extension 33% of the variance was accounted for by the modified sit-and-reach and for hip flexion 22% of the variance was accounted for by the modified sit-and-reach.
However it is noticed that there is a shift of the ribcage which would indicate a shift in the shoulders, the shift of the ribcage is clear in the video footage of the roll down posteriorly as the model rolls to the right on the way down which could mean the dancer has a tight right side. In the roll down the model hinges when the roll down reaches her lumbar spine that is due to a tight back. As well as a tilt the model has a rotation in the torso to the right this is sighted in appendices 1 and 2 the lateral views of the model this is because whilst looking at appendix 1 you are able to see the models left arm as well as the models right arm however in appendix 2 you are only able to see the models left arm which signifies that the model has a slight rotation in the shoulders also. The model has a right lateral tilt in her
The scale is broken up into classifications A, B, C, D, and E. Classification “A” represents the most severe impairment indicating a complete lesion with no signs of sensory or motor function in the sacral segments. Classification “B” represents an incomplete lesion. Some sensory function is present but motor function is lost below the neurological level. Classification “C” represents an incomplete lesion. Motor function is present in this classification and more than half of the muscles below the point of injury have a muscle grade less than 3. Classification “D” represents an incomplete lesion, motor function is present, and at least half the muscles below the point of injury have a muscle grade of 3 or greater. Classification “E” represents the best outcome and indicates that all sensory and motor functions are intact (p.
Modifications of the original posture have been used in diverse situations, with applications found for “high,” “low,” and “reverse-Trendelenburg.”
Proper positioning of patient is one of the most significant components of physical therapy. Safe and comfortable position is recommended by health care professional. This process should apply immediately after accident and continue during all phases of recovery. Suitable positioning assists in stimulating motor function, raises sensory awareness, improve respiration and can help normal range of motion in trunk and extremities. One of the most important effects of positioning is to prevent pressure ulcers. Mostly patients lie on back, involved side of non-affected side. The body points that should be considered are shoulder and pelvis. Gluteus maximus and rhomboid muscles become stiff retract shoulder and pelvis. Due to this, shoulder and pelvis must be positioned in a bit protraction in order to decrease spasticity and tightness.(Mehrholz, 2012)
Response: since the AP clavicle and AP axial do not require much movement both projection can be taken with minimal positioning modification. The image was taken without placing the arms on the sides. Both shoulder were position at equal distances from the IR and the mid coronal plane straight and align parallel to the IR.
The adductors as a group are really a powerhouse. They have a lot of combined muscle fibers and through their attachment sites on the pelvis and the femur, significantly influence the body’s alignment. Because they originate and have such a presence on the pelvis, shortened adductors will influence the tilt and transverse rotation of the pelvis. The thorax is intimately connected and sometimes anchored to the pelvis through muscles such as the Quadratus Lumborum, the Rectus Abdominis and the Transverse, Internal and External Obliques. Any shift in the pelvis toward neutrality as a result of bodywork on the adductors will directly affect the muscles that connect the pelvis and the thorax and thus will create space for the thorax to shift
A normal human thoracic spine begins at the first vertebra (T1) and ends at the twelfth (T12). When viewed laterally (side), the thoracic spine presents a normal forward curvature, which ranges from twenty to forty-five degrees in roundness (Scoliosis Research Society, 2015). Excessive curvature that exceeds forty-five to fifty degrees causes an abnormal slouched posture known as kyphosis. According to Kamiah A. Walker (2011), “The vertebrae stack one on top of each other and are supposed to be rectangular” (para. 11). However, Walker adds that kyphosis “causes the vertebrae to become triangular or wedge shaped” (2011, para. 11). This results in an inward and forward postural change of the upper spine.
The sagittal axis splits the body with an imaginary line into left and right halves and the frontal plane splits the body with an imaginary line into front and back halves. The movements that occur in the frontal plane about the sagittal axis are lateral flexion – tilting the head to one side, radial and ulnar deviation of the little finger from the wrist to the side, inversion and eversion which tilt the sole of the foot towards or away from the midline of the body, adduction and abduction which is moving a body apart towards or away from respectively of the body’s midline (arms / legs for
PNF rolling started with the patient lying supine and instructed to roll towards right side lying with the left elbow and knee coming in contact once right side lying was attained, and terminating the sequence by rolling back into supine. Once the patient was able to complete the sequence of movements correctly, he was instructed on inhaling during the rest period and exhaling as he rolls. When the entire sequence was demonstrated correctly, manual resistance was added to the left anterior shoulder girdle and hip. The patient performed ten repetitions rolling to the right and then to the left. Then manual resistance was removed, and the patient then performed ten alternating rolls to each side. After the first week of treatment, the patient fully understood the sequence of movements and required less practice before initiating manual resistance. This style of PNF was chosen to integrate core and trunk engagement during more functional activities.10 The coordination of trunk engagement during rotational and reciprocating movement is necessary to accomplish the pre-established long-term goals of stair climbing, running, and return to recreational

Posture is one of the most important factors of our bodies when it comes to exercise. There are a few very common postural deviations and most people suffer from at least one of them, so I performed a posture test on myself and Victoria to evaluate our current posture for deviations. The standard posture test, included standing up with our back towards a wall, making five points of contact with the wall. If all five points, including heels, calves, buttocks, upper back, and head can make contact easily or without much strain, good posture is determined. If all five points do not touch, then you will see where and what postural deviations are present.
