“…The selection of specific-VM and general exercises was based on the findings from two systematic reviews assessing interventions for people following FTPD [8] and electromyography (EMG) preferential activation of the distal VM [13][14][15][16][17][18]. From this available EMG data, four exercises were identified which provided some evidence that the distal VM may be preferentially activated during these activities.…”

“…Nonetheless, a small number of studies have demonstrated the preferential recruitment of this muscle in either healthy or patellofemoral pain (PFP) populations [13][14][15][16][17][18]. Nonetheless no studies have assessed whether this can influence clinical outcomes in people following FTPD.…”

“…However, questions remain regarding whether the VM can be preferentially recruited [10]. Accordingly, although some clinicians continue to prescribe specific-VM exercises [9], there is uncertainty that this can actually preferentially recruit this muscle rather than recruiting the quadriceps globally [10,12].Nonetheless, a small number of studies have demonstrated the preferential recruitment of this muscle in either healthy or patellofemoral pain (PFP) populations [13][14][15][16][17][18]. Nonetheless no studies have assessed whether this can influence clinical outcomes in people following FTPD.…”

“…Numerous studies have demonstrated that isometric and isokinetic quadriceps exercises can significantly increase knee extension strength over three week [36], eight week [37] and five month periods [38]. Whilst the specific-VM exercise programme used in this trial was based on EMG studies which have demonstrated an ability to preferentially recruit the VM [13][14][15][16][17][18], it was expected that this exercise programme could also increase knee extension strength [30,39]. Whilst not statistically significant, there were small mean differences in isometric knee extension strength between the groups at each follow-up period.…”

Rehabilitation following first-time patellar dislocation: A randomised controlled trial of purported vastus medialis obliquus muscle versus general quadriceps strengthening exercises

Purpose: Define whether distal vastus medialis (VM) muscle strengthening improves functional outcomes compared to general quadriceps muscles strengthening following first-time patellar dislocation (FTPD).Methods: Fifty patients post-FTPD were randomised to either a general quadriceps exercise or rehabilitation programme (n=25) or to a specific-VM exercise and rehabilitation regime (n=25).Primary outcome was the Lysholm Knee Score, secondary outcomes included the Tegner Level of Activity Scale, the Norwich Patellar Instability (NPI) Score, and isometric knee extensions strength at various knee flexion ranges of motion. Outcomes were assessed at baseline, six weeks, six months and 12 months.Results: There were statistically significant differences in functional outcome and activity levels through the Lysholm Knee Score and Tegner Level of Activity Scale at 12 months in the general quadriceps exercise group compared to the VM group (p=0.05; 95% CI: -14.0 to 0.0/p=0.04; 95% CI: -3.0 to 0.0). This did not reach a clinically important difference. There was no statistically significant difference between the groups for the NPI Score and isometric strength at any followup interval. The trial experienced substantial participant attrition (52% at 12 months). Conclusions:Whilst there was a statistical difference in Lysholm Knee Score and Tegner Level of Activity Score between general quadriceps and VM exercise groups at 12 months, this may not have necessarily been clinically important. This trial highlights that the recruitment and retention of participants from this population is a challenge and should be considered during the design of future trials in this population.

The estimated incidence of patellar dislocation is between 7 [2] to 77 per 100,000 people per year [3], with a marginally greater incidence in females [2,4]. The term first-time patellar dislocation (FTPD) represents the first episode that the patella disengages completely from the femoral trochlear. It is sometimes termed primary patellar dislocation [5].Conservative (non-operative) treatment is the treatment of choice for FTPD. Quadriceps strengthening exercises are considered one of the principal management for people following FTPD [6,7]. A United Kingdom (UK) survey of physiotherapy practice has shown that quadriceps strengthening and specific-vastus medialis obliquus (VMO) or distal vastus medialis (VM) muscle strengthening or recruitment exercises were two of the most frequently used interventions for this population [1]. However, there remains controversy rega...

“…The most frequently described cause of anterior knee pain is patellofemoral pain syndrome [27]. The trajectory of patella movement during extension is modified by the joint's surfaces and the tension of active stabilizers -the vastus lateralis and vastus medialis muscles [28]. Dieter et al noticed that people with patellofemoral pain syndrome have a different thigh muscle activation time than the control group, and that these muscles are responsible for the syndrome [29].…”

Introduction. The number of cyclists increases each year. Some people treat cycling as a passion and practice it at every possible occasion, while for others it is a mean of transport or a form of relaxation at the weekend. However, very few people realize that cycling can also have a negative impact on their health. Objective. To assess the prevalence of lower extremity and spine pain in cyclists, and evaluate the influence of various factors causing it. Materials and method. The study was performed on 167 subjects during amateur cycling competitions in the Greater Poland and Kuyavian-Pomeranian Provinces. A specially prepared questionnaire was used in the study. The questions related to the pain caused by cycling, the character and the localization of the pain, and the presence of warm-up and stretching. Results. Knee pain was reported in 40% of the study subjects (mostly anterior pain -26%). Spine pain was reported in 41% of the studied athletes, where 26% was related with the lumbar spine. Variables, such as age, weight, age, BMI, training experience and number of hours devoted to training per week had no influence on the incidence and the localization of leg pain, but it had influence in the case of spine pain. Stretching after cycling was the factor which significantly distinguished the studied groups with regard to the incidence of knee pain. Conclusions. The most common type of leg pain was knee pain (anterior knee pain) whereas spine pain was most commonly reported in the lumbar spine. Statistical analysis showed that spine pain is more often reported by people who are older, have higher weight, and people who spend more time training per week. Warm-up and stretching after cycling are recommended to cyclists who experience pain.
