The change of vertical ground reaction force and loading rate rate is a important factor in causing patellofemoral pain (PFP). The aim of this study was the effect of sensory-motor exercises on the vertical ground reaction force and loading rate in patients with PFP when stair descent.

A total of 30 patients with PFP participated and were randomly divided into two experimental and control groups (15 subject in each group). Over a period of twelve weeks, the experimental group engaged in sensorimotor exercises, while the control group did not receive any therapeutic intervention. Pain intensity, fear of movement, quadriceps muscle strength, knee flexion angle, components of vertical ground reaction force and loading rate were evaluated in two stages pre-test and post-test. For data analysis SPSS 16 software and the covariance statistical method were used to compare the results between groups, and the significance level was considered 0.05.

The analysis of covariance analysis indicated that sensorimotor exercises in the experimental group compared to the control group had a significant difference in reduced pain (P >0.001), reduced fear of movement (P >0.001), incresed quadriceps muscle strength (P >0.001), incresed knee flexion angle (P >0.001), components of vertical ground reaction force (P >0.001), and reduced loading rate (P >0.001).

The finding suggest that the experimental group experienced a boost in in quadriceps muscle strength, leading to diminished pain and fear of movement, an increase in knee flexion angle, and enhanced active shock absorption. Consequently, there was an increase in both peak forces while the loading rate and valley force decreased.

Disruption in biomechanics and kinematics of the lower extremity is one of the causes of knee patellofemoral pain syndrome. The purpose of this study was Comparison the effect of selected lower extremity movement pattern and traditional exercises on pain and quality of life in male athletic with patellofemoral pain syndrome.The Present research was semi-experimental and pre-test and post-test.The statistical population of this research is all men aged 18-28 years old with patellofemoral pain in Shiraz city who referred to Hadi sports medicine clinic. A number of 30 people from the aforementioned community were randomly and available purposefully selected and randomly placed in two movement pattern groups (15 people) and traditional (15 people). Subjects signed a personal consent form before participating in the exercise program. Each group had their own exercises for eight weeks, three sessions each week, and each session lasted 60 minutes. Before and after the training period, pain and quality of life were measured using visual pain measurement scale (VAS) and quality of life (SF-36), respectively. To were analyze the data, statistical test of variance was used for covariance data at a significant level (p<0.05).The results showed that the exercise program for correcting the movement pattern of the lower extremity significantly improved the level of pain (ES=0.7, P<0.05 and F(1,28)=15.32) and quality of life (P>0/005 and F(1,28)=27/02 , ES=0/6). Also, the results showed that the traditional exercise program significantly improved the pain level (ES=0/5, P<0.05, and F(1,28) =8/24) and quality of life (ES=0/4, P<0.05 , F(1,28)=27/02 ). The exercise program was effective in both groups, but the exercises in the movement pattern group were more effective on pain and quality of life than the traditional group.The biomechanics of the lower extremity are disturbed in patients with patellofemoral pain syndrome, and the exercises performed on these people should cause changes in the biomechanics of the lower extremity and finally align the joints.

Fatigue of the quadriceps muscle causes pain and decreased knee proprioception. The aim of research was the effect of two PNF stretching programs and lower limb strengthening on pain and knee proprioceptive of the knee joint before and after local fatigue of the quadriceps muscle in male athlete with patellofemoral pain.

This research was semi-experimental and pre & post-test. The statistical population included men aged 20-30 with patella pain in Tehran. 24 people were placed in two groups of PNF stretching exercises (12 people) and strengthening (12 people) in a targeted and random selection. All subjects signed a personal consent form before participating in the study. Each group did their exercises for eight weeks and three 60-minute sessions each week. Before & after the exercises (before and after the test), knee pain and proprioceptive sensation were measured using visual pain measurement (VAS) and biodex isokinetic (model IV Pro made USA), respectively. Data were analysis significant (P<05/0) using the combined repeated measure.

the comparison of the first and third tests (before fatigue) (ES=0.5, p<0.05 and        F (1,22) =4.417) . The comparison of the second & fourth tests after fatigue(ES=0.8, p<0.05 and F (1,22) =148.4), there was a significant difference (ES=0.4, p<0.002 and F (1,22) =52.14). Pain reduction after training was 29% in the stretching group 18% in the strengthening group. The net effect of training on depth sensation improvement was significant (ES=0.6, p<0.005 and F (1,22) =2.404). Regarding the comparison of the first & third test (before fatigue) (ES=0.6, p<0.001 and F (1,22) =108.2). The comparison of the second & fourth test (after fatigue), there was a significant difference (ES=0.5, p<0.002 and F (1,22) =51.1). The improvement in proprioception after training was 15% in the stretching and 11% in the strengthening group. The exercises in the PNF stretching group were more effective on both variables in the post-test and after the training period.

Both exercise programs have been concluded for pain factor and proprioception, but the effect of PNF training to reduce pain and improve proprioception of patients was the amount of consumption.

Patellofemoral pain syndrome is a term used to describe pain that originates in the patellofemoral joint or the soft tissues surrouning it. This study compared the effects of relaxation tones and mindfulness-based breathing on the magnitude of the ground reaction force experienced by patellar femoris patients while walking to those of transcranial stimulation of the primary motor cortex.

Thirty men with patellofemoral pain participated in this semi-experimental study. With the aid of a force plate device, ground reaction force variables were assessed before and after transcranial stimulation, relaxation, and mindfulness-based breathing. The data were statistically analyzed using a two-way analysis of variance with a significance level of 0.05.

The results showed that the effect of the time factor was statistically significant on the peak internal-external force during heel contact (P=0.049), when the foot leaves the ground (P=0.001), the peak anterior-posterior force during heel separation from the ground (P=0.044), and the peak vertical ground reaction force during heel separation from the ground (P=0.011). The effect of the time factor was statistically significant on peak internal-external forces during heel contact (P=0.004), peak anterior-posterior forces when the foot leaves the ground (P=0.017), peak vertical forces during heel contact with the ground (P=0.009), and peak vertical forces during foot separation from the ground (P=0.047).

Based on the findings, it can be inferred that transcranial stimulation of the primary motor cortex, as well as body relaxation and mindfulness-based breathing awareness may be effective in reducing patellofemoral pain.

Disorders in the lower extremities biomechanics and kinematics are one of the causes of patellofemoral pain syndrome. The aim of this study was to investigate the lower extremities biomechanics of the in patellofemoral pain syndrome: a narrative review of the articles 2020-2010.

Patellofemoral Pain Syndrome is a common type of musculoskeletal disorder of the knee with a variety of therapeutic approaches, including surgery, kinesio taping, exercise therapy, physiotherapy, orthosis, and prosthesis. The aim of this study was to investigate the examination of strengths exercise performed on Patellofemoral Pain Syndrome with emphasis on muscle weakness.

The present article is a narrative review that with a systematic electronic search of databases (Google Scholar, Taylor & Francis, Springer, Magiran PubMed and ISC) applied to download related articles from 2010 to 2020. Keywords were “Patellofemoral Pain Syndrome”, “Strength Training”, and “Proximal Training for PFPS”.

After reviewing 324 articles, 64 related articles on exercise therapy were found. After reviewing the articles in terms of the quality of the paper, 17 articles that reviewed the strengthening exercise program looked at muscle weakness in people with patellofemoral pain syndrome, selected and their effect on improving pain and performance in people with patellar pain were investigated.

Strengths exercise has been shown to be effective in improving pain and performance in people with patellofemoral pain syndrome, but exercise that not only strengthens the muscles in the knee area but also strengthens the muscles in the lumbar-pelvic girdle showed more improvement than exercises that only focused on strengthening of the muscles of the knee joint.

Patellofemoral pain is the most common and controversial musculoskeletal problem. Several studies have focused on its causes, prevention, and treatment strategies. This study was done to determine the effect of eight weeks of standard and functional stabilization training on pain and functional movement of women with patellofemoral pain.

This quasi-experimental study was performed on 45 non-athletic women with patellofemoral pain syndrome aged 18-35 years. Subjects were divided into three standard, functional stabilization training and the control group and followed for 8 weeks. Pain was measured by visual analogue scale and functional movement was measured by the KUJALA (Anterior knee Pain Scale).

Severity of pain significantly reduced in the two interventional groups (standard and functional stabilization training) in comparison with control group (P<0.05). Functional movement significantly increased in the two interventional groups in comparison with control group (P<0.05). Severity of pain and functional movement had no significant difference between the two intervention groups.

Performing each of the exercises, standard or functional stabilization training, for eight weeks, had beneficial effect on reducing pain and improving functional movement in patients with patellofemoral pain syndrome.

The aim of the current study was to investigate the effect of hip abductor and external rotator muscles strengthening exercises on pain, muscle strength, and lower extremity kinematics in people with patellofemoral pain (PFP).

A total of 35 patients with PFP were randomly assigned into exercise and control groups. The exercise group received abductor and external rotator strengthening exercises with thera-band 3 times per week for 12 weeks. The control groups did not receive any training intervention. Then, the two groups were compared to study the effect of independent variable on the experimental group. Pain (VAS), hip muscle strength (handheld dynamometer), and lower extremity kinematics (video analysis) were assessed at baseline and post-intervention. Participants included patients with bilateral or unilateral patellofemoral pain; if pain was bilateral, exercises were performed bilaterally on both lower extremities but measurements were performed only on the lower extremity which was more painful; whenever the pain in both knees was equal, data were collected only from the superior lower extremity. Repeated measures ANOVA was applied using SPSS to assess the effects of the exercises on measured variables.

Pain decreased significantly in exercise group from baseline to post-intervention (P=0.000). Hip abductor muscles strength (women, P=0.000 and men, P=0.003) and external rotator muscles strength  (women, P=0.024 and men, P=0.000) increased significantly in exercise group after 12 weeks of strengthening program. There was a significant improvement in dynamic knee valgus during single-legged squat (women, P=0.018 and men, P=0.017) and contralateral pelvic drop during stair descending just in women (P=0.04) in exercise group. There were no significant differences between men and women in the effect of exercises on the variables studied (P>0.05).

According to the results, hip strengthening can decrease pain, increase muscle strength, and change kinematics in the frontal plane movement patterns of the lower extremity, which can possibly be the mechanism of effect of this intervention on PFP symptoms. According to findings of the present study, it might be concluded that gender-specific rehabilitation program is not needed in patients with PFP.

Previous studies suggest that hip muscle weakness may contribute to patellofemoral pain (PFP). Accordingly, addition of hip strengthening exercises to conventional knee exercises was recommended for treatment of PFP. However, evidence to support superior efficacy of additional hip exercises in treatment of PFP is limited. This study compared the clinical efficacy of knee exercises versus combined knee and hip exercises in females with PFP.
In this randomized clinical trial 60 females with PFP were randomly assigned into two groups: “the knee exercises” and “the knee and hip exercises”. Participants performed progressive therapeutic exercises 3 times a week for 4 weeks. Pain, muscle strength (the knee extensors, the hip abductors and the hip external rotators) and physical function were evaluated before and after treatment interventions using Visual Analogue Scale (VAS), a dynamometer, and step-down test, respectively.
Both groups showed significant improvements in pain, function, and the knee extensor, hip abductor and hip external rotator muscles strength after the interventions (P0.05).
Four weeks of either knee exercises or combined knee and hip exercises significantly improve function and reduce pain in women with PFP. Addition of hip strengthening exercises to conventional knee exercises was not associated with superior treatment outcomes.
