A Study On Open Chain Exercises

Provided to each subject was a consent form to review and sign before their participation in this study. The researcher excluded any identifiable information from the data collection measures. Subjects received a number as they signed in for the information session. The researcher used these numbers to link the subjects to their surveys and their clinical assessments. Their numbers coordinated with the attendance form which was in the sole possession of the researcher. Institution

A researcher has designed a study to test the effects of different types of individual psycho-therapy on people's levels of anxiety. She has randomly placed people into one of three groups: a behavioral treatment group, a psycho-dynamic treatment group, or a no-treatment control group. She then measures people's level of anxiety after the treatment.

Thus obtaining on proposed rehabilitation program in accordance with the scientific foundations in order to achieve the desired benefit which represents in enhancing the functional efficiency of athletes after ACL surgery for return to their preinjury state and participate in their sports activities.

A research team leader will randomly select eligible participants and divided them into two equal groups, A and B. Group A pre-intervention and Group B post intervention. There are multiple delivery methods available for collection data such as interview (one-on-one, via telephone or in person), focus groups, and observation. The traditional method paper-and-pencil survey whose results are subsequently entered into a software program will be used as well as an online based collection to reducing the cost of data collection and encouraging voluntary participants. The data will be electronically downloaded directly to an Excel spreadsheet for analysis and minimizing data entry error or bias. There will be four different types

The study consisted of fifty, female, undergraduate college students. The ethnicities that were use for this study were African American, European, Asian, Hispanic, biracial, and a very slight percentage was categorized as other. The experiment would begin at 5:00pm everyday, for four weeks. One of the three groups was administered each day. The three groups were either peppermint, expectation, or control. Each participant was seated down, given an instruction sheet, a laptop, and was not able to see the other participants from their view.

In addition, regression analysis was used to determine independent variable among age, BMI, grip strength, sex and K/L grade for knee pain. The result indicated that the most significant variable was BMI correlated with the occurrence of knee pain. ORs of BMI (+5 kg/m2) was 1.54 and the risk was 0.60 which was significant. This implied that the ORs of K/L grade for knee pain can be overestimated due to the possibility of extremely low risk of K/L grade. In fact, the percentage of participants who suffered from knee pain with K/L (grade 2) and K/L (grade 3 and 4) was just 61.0% and 71.0% respectively. In other words, it will be about 40% of participants with K/L grade 2 and about a third of subjects with K/L grade 3 and 4 had no pain at the knee joint at follow-up.

Within the study, the demographics of the participants were made available, including gender, age, race and ethnicity, marital status, and educational and employment status. Special consideration and statistical analysis was conducted for those in the High

The purpose of ACL reconstruction is to restore function by repairing normal movements, replicate knee anatomy, and to protect the knee for a long duration. More specifically, the dimensions, orientation, and insertion sites of the ACL must be restored. To ensure this, future consideration for improvement of ACL reconstruction surgery is vital.

The purpose of this article is to compare the laxity and stiffness of the knee joint in male and female cadavers. Three different directions will be evaluated, anterior-posterior, internal-external, and varus-valgus. Females are at a two to eight times greater risk of an ACL injury than a male. This is due to the laxity in the joints. Females also have limited proprioception in the knee joint, which may attribute to some injuries. This study used a technique using cadaver knees to complete this study.

This study included 28 patients who underwent ACL surgery performed by the same 2 surgeons and standard rehab protocol was done in the same physical therapy clinic, with all the same exercises and progressions. The Battery Test uses exercise analysis to grade the participants. The exercises include measurement of isokinetic strength, single hop for distance, triple hop, side hop, and a jump-landing assessment. There were also patient surveys that asses their feelings about the overall health of their knee. The participants completed this testing 6 months after surgery, which is the average RTP time frame for basic ACL rehab protocol. Out of all 28 patients, only 2 individuals passed this test and can be considered safe for RTP. This information is extremely important for anyone who has the authority to grant RTP to any athlete. Allowing patients back to play too soon is extremely dangerous and can cause further injury. Using this specific test to determine RTP decisions is a great technique to utilize in athletic

2001, Withrow, Huston et al. 2006). Quadriceps inserts on the proximal-anterior part of tibia and isolated contraction of the muscle will cause anterior translation of tibia in relation to femur, putting strain on the ACL and possibly rupture the ligament (Renström, Arms et al. 1986, DeMorat, Weinhold et al. 2004, Withrow, Huston et al. 2006). Furthermore, landing and cutting manoeuvres produce abduction, adduction and rotational torques about the hip and knee (Besier, Lloyd et al. 2001). Without an opposing force to these torques the loaded leg(s) will be forced into the valgus position with the femur adducted and internally rotated, the tibia externally rotated and the knee abducted further increasing strain on the ACL (Markolf, Burchfield et al. 1995). Ireland (2002) has characterized this the position of no return, unassumingly because it habitations the stabilizing muscles of the knee in a mechanical disadvantage disabling them from re-establishing a sound posture. I should notate that several studies have associated this position of no return to an increased risk of knee injury. Female athletes exhibit increased knee valgus 6 movement patterns during landing and cutting activities compared to male athletes (Chappell, Yu et al. 2002, Ford, Myer et al. 2003, Zeller, McCrory et al. 2003, Olsen,

The overall objectives that were taken under consideration included nearly all aspects in regards to functionality of the knee (14). Many studies have placed patients recovering from ACL reconstruction on rehab regimens with the hope to improve various aspects concerned with how well and at what levels the knee can function. Treatment programs, accelerated or non-accelerated commonly encompass similar exercises and physical activity such as stretching, strength training, and activation of muscles through electrical stimulation. The intensity and general progression of therapy is where the two significantly contrast. With the use of weight bearing exercises, or strength training within the accelerated regimen, it has been proven to limit muscle weakness as a consequence of immobilization after surgery. Shelbourne carried out this method of intervention every week, 2-3 times per week, while progressively increasing weight and the degrees to which the knee was stretched. The results were assessed using The Cybex Isokinetic Device, a

All patients included in the study were recalled for subjective, objective, and functional evaluation; the study protocol involved the range of motion (ROM), ligamentous stability, Tegner-Lysholm Score, Modified Cincinnati Rating System Questionnaire, Short Form-12 (SF-12) in addition to the plain radiograph, computed tomography (CT), and magnetic resonance imaging (MRI) of the knee. According to international knee documentation committee (IKDC) score, any development of arthrosis was assessed at the final follow-up.

Osteoarthritis is the most common joint disorder, and more than half of all Americans who are older than 65 have been diagnosed with osteoarthritis. However, recent US data has revealed knee osteoarthritis does not discriminate age, and there is growing evidence that osteoarthritis affects individuals at a young age. The annual cost of osteoarthritis due to treatment and loss of productivity in the US is estimated to be more than 65 billion dollars.1 With no cure currently available for osteoarthritis, current treatments focus on management of symptoms. The primary goals of therapy include improved joint function, pain relief, and increased joint stability. Although the exact cause of osteoarthritis is unknown, many risk factors have been identified including increased age, female gender, obesity, and trauma.2 Within these risk factors, the etiology of osteoarthritis has been divided into anatomy, body mass, and gender.
