the effect of treatment based on movement system impairment classification theory in people with knee pain (a randomized control trial)

the investigation of the treatment effect based on movement system impairment classification theory in people with knee pain

a randomized controlled trial with equivalent intervention and control groups, single blinded on 60 patients, consecutive simple individual randomization (in order of referral)

place: Shahid Beheshti physiotherapy clinic. After examination and diagnosis of movement impairment, the expert colleague classify them into intervention and control groups randomly. During 10 sessions in 6 weeks, researcher accomplishes the predetermined physiotherapy treatments for each group. data collection, outcome measure assessment , data analysis is done by the colleague,using questionnaires for investigating function and disability, visual analogue scale and video camera to recording knee projection angle

inclusion criteria: patients with knee rotational syndrome or patellar lateral glide syndrome. Pain at least 3 on the visual analog scale. knee Pain during running or jumping. exclusion criteria: pregnancy

intervention1:patients with knee rotation syndrome with valgus control 1: patients with knee rotation syndrome with valgus intervention 2:patients with knee rotation syndrome with varus control 2: patients with knee rotational syndrome with varus intervention 3:patients with patellar lateral glide syndrome control 3: patients with patellar lateral glide syndrome similar treatments for control groups:10 sessions in 6 weeks: , electrotherapy,Ultrasound, exercices. intervention groups : the above treatment plus education and modification of functional activities, improve performance of hip lateral rotators and abductors and extensibility of iliotibial band

pain intensity, disability Level, Function level, Knee frontal plane projection angle.

the sampling method in the present study is consecutive. It means that the expert colleague gets present at the patients' referral site (Shahid Beheshti rehabilitation clinic) from the beginning of the study, and patients who are eligible to participate in the study are identified and then, invited to participate in the study. Therefore, randomization is occurred consecutively. It should be noted that only one rehabilitation center is sampled in this study. In this study, simple randomization method is used and randomization unit is individual. In this way,the eligible participant with diagnosis of having one of the three identified movement impairment syndrome is classified to a primary group with the other ones with the same impairment first. then in each group with the same movement impairment people are numbered by order of their referral. individuals who the odd number assigned to them are included in intervention group and participants with the even numbers are included in control groups.for example, if the primary diagnosis is rotational syndrome with varus,number one is assigned to the first participant with this movement impairment and number two assigned to the second one with the same diagnosis. so the first odd number is included in intervention group for rotational syndrome with varus and the second person with this syndrome with even number two is included to control group of the same subcategory and the way is continued until the assigned number of each group are entered in to the study for this diagnosis group. randomization for other subcategories are done the same way based on their primary diagnosis and by order of their referral.

In the present study، the expert experienced colleague who has passed more than 100 hours instructions in clinical diagnosis of movement system impairment is responsible to do: 1-Systematic examinations and diagnosis the movement system impairments of the clients 2- Randomization of participants into intervention or control groups. All of these procedures are done based on the study inclusion criterion and clinical recognition conceptions of the movement system impairment theory, furthermore; the researcher is blind to them. But all treatment sessions are done completely by the researcher. All intervention groups are treated specifically based on the movement system impairment classification theory for knee pain and all control groups treatments are based on routine treatment protocols for knee pain suggested by physiotherapy reference texts. Data collection in predetermined times is done by another co worker who is blind same as the researcher. Outcome measure assessment and data analysis are done by statistics consultant of the project but the researcher is also blind to all of these.
