A Relationship Between Shoulder Flexion Angle And Mobility Measured Through A Tug Test

On the downward phase flexion occurs at the knee, stopping at about 90 °. Both quadriceps, acting as the agonist to flex the knee, and hamstrings, which mainly stabilizes the knee, act as an antagonistic pair and co-contract eccentrically to allow flexion. The hamstring is also acting as the synergist for the hip joint (Tortora and Derrickson, 2009). The Sartorius acts as the synergist and also contracts eccentrically to cause flexion at the knee (Wynsberghe et al., 1995).

Osteoarthritis (OA) is a chronic joint disorder; knee is the joint that most frequently affected.1 During 1988 to 1994, among US adults, the prevalence of knee OA was 37.4%, and the prevalence was greater among women than men (42.1% vs 31.2%).2 Knee OA will impair lower extremity function, and influencing the quality of life. The most common complaints from the patients with knee OA are the pain, daily functional decline, joint deformity, and gait deviation3,4. Symptomatic OA knee patients have shown that significantly less knee angular velocity and knee range of motion during gait. The normal joint load line can be altered with possible varus angulation of the knee, eventually affecting

1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1, 22) = 9.619, p = 0.005. Discuss each aspect of these results.

The rectus femoris crosses both the hip and knee. In order to test its passive sufficiency, either of the joints ranges of motion could be measured. In this example, range of motion will be measured at the hip. The rectus femoris will be most constrained when the knee is flexed and the hip is extended. For this test, the

When an ACL is torn there is usually a whip-like snap of the lower extremity that can be observed as the ACL tears (Ireland, 1999, p.152). In visualizing this high-risk ”position of no return,” we comprehend the importance of a “get-down” knee-flexed, 2-footed balanced position (Ireland, 1999). In the no-return position, the hip abductors and extensors have shut down, and the pelvis and hip are uncontrolled.

Patients were examined using the active compression (O’Brien’s) test, biceps load II test, dynamic labral shear test (O’Driscoll’s), Speed’s test, and the labral tension test. The same physician performed all

The purpose of this experiment was to identify which flexibility measurement tests correlate with the sit-and-reach and modified sit-and-reach tests. In more recent studies, statistics have shown that both hip flexion test results and shoulder extension test results were directly correlated to modified sit-and-reach test results (Mayorga-Vega, Merino-Marban, and Viciana, 2014). The data gathered for the sample

The Modified Thomas is common test that used to assess hip extensibility and determine the existence of hip flexion contracture. Various athletic activities can be significantly affected by the lacking of hip extension and the tightness in the hip flexor muscles. A deficient in hip extension can lead to altering the gait pattern (overstriding gait ) and raised the impact forces during running and then elevates the risk of tibial stress fracture. In the original Thomas test, the participant lies on his back upon an examination table; the participant flexes and hold one knee at the chest. The other leg should remain relaxed upon the tabletop. The positive test will be documented if a gap between this leg

The paper presents the force equation generated by the muscle group, the equation between the moment and the EMG signal. Use software to simulate the dynamics generated by the knee joint. Use the Arduino Uno driver to read signals from the EMG sensor, and store values to the SD card. Using Excel software to process data, create a status chart of the experimenter in knee flexion. The results show that the EMG signal readiness histogram has the same relationship as the dynamical simulation chart with the Matlab software. This is the basis for the calculation of the optimal parameters for the relationship between momentum produced by the muscle group and the EMG signal. In the next study, we will evaluate the baseline levels for patients with

Next let's measure the amount of flexion or bending of the elbow. Position the patient in the correct position to measure this motion. Now place the goniometer on the patient so the axis or center of the goniometer is in the correct position to measure elbow flexion, remember this motion is when the patient bends the elbow bringing the palm towards the

(2008) wrote a case study report to explain the benefits of using a dynamic splint for knee flexion contracture patient after TKA as an add on treatment with the physiotherapy in reducing the knee flexion contracture. In the experiment, physiotherapy was the primary intervention for the patient after one month of TKA surgery. The exercises that were prescribed to the patient includes a combination of ROM, closed and open kinetic chain strengthening exercises and balance exercises that involve trunk and lower limb muscles. Following the 28 physiotherapy sessions, a DS was prescribed to the patient to wear at night time (while sleeping) in order to increase the patient’s time at total end range of knee extension. DS act as a second intervention in reducing the knee flexion contracture in the patient. He explained the benefit of using dynamic splinting to reduce the contracture of the knee and achieve full knee extension after a TKA due to its low-load and prolonged stretching duration with the dynamic tension provided by the splint. However, additional stretching would help in reducing the contracture rather than continuous passive

This proposal is innovative because it combines a proven, effective exercise protocol with Vibromyography (VMG) Assessment tests to accurately measure the knee ROM and strength gains post surgery (1). Measuring the knee ROM and strength of the quadriceps will help determine whether or not an accelerated exercise intervention will yield better results, and in a shorter duration, compared to a traditional, non-accelerated intervention. Evaluating the knee range of motion and strength of the muscles surrounding the quadriceps will conclude whether or not the accelerated exercise intervention will be effective because it looks beyond the simple, quantitative scope of functional ability and knee stability, but rather will measure knee characteristics

The techniques used to evaluate and manipulate the data involve linear regression and correlation methods. The researchers chose linear regression and correlation techniques because the analysis involves a comparison of the degree of relationship between the assessments done by patients and the analysis of clinical officers (Price, 2014). Also, the analysis involved statistical elements such as phi-coefficients and Pearson's correlation coefficient, r. Pearson’s correlation coefficient has been used to test the linear relationship between information given by patients and those collected by nurses.

The goniometer measure was used to assess the range of motion during this study. The intraclass correlation coefficients (ICC) for test-retest reliability of the shoulder is between .6 and .69. A previous study on the kinesiologic electromyographic have demonstrated that the interrater kappa coefficient for identification of muscles weakness without using a muscle test grade is between .62 to .69 for muscles of the rotator cuff. The interrater reliability for muscle stretch reflexes is around .73, with a specificity value ranging from .95 to .98 and sensitivity ranging from .03- .24. The interrater reliability for dermatomal sensory testing for C5 distribution around .67. The Spurling test for cervical radiculopathy had
