I wouldn't bother attempting to reason with Sicknote....lots of supratentorial vacuum....from what I have seen. -
One problem is lack of core strength (pelvic stabilisation). How about too much sitting?. But the most overlooked is too do with the diet. People don't realise what affect certain foods/beverages have on stiffening/tightening the body (muscles/tendons).
Take people who drink coffee & also do yoga for example. Completely counter productive. -

Ok, now show that it works in patients with knee pain and whether or not their knee pain improves.
Also, how about testing it while they run, if that is possible, to see if they can do what they were trained to do with their glutes statically.

Comparison of the Activity of the Gluteus Medius According to the Angles of Inclination of a Treadmill with Vertical Load

What this study showed that gluteal activity was different in those who had achilles tendon problems, which could mean:
1) Glut problems caused the achilles problem due to a gait alteration
or
2) The pain in the achilles tendon changed the gait and that altered the EMG pattern in the glutes.
I think the overwhelming consensus of pretty much everyone (except for the fan boys) would agree that its probably (2) is the most likely explanation for the findings in the study in the absence of any other evidence. There is certainly nothing in the study saying that the gluts need to be treated in those with achilles problems.
Having said that, I just picked up this comment in a blog post (ie it carries a lot of weight :dizzy:):Runners who don’t engage their glutes tend to push with their toes instead of with their glute muscles, especially when trying to run fast. That kind of stress can cause inflammation {in the achilles tendon}.Click to expand...Craig Payne

It’s almost always an overstriding problem,” said Uhan. When your foot lands in front of your trunk, especially if you land on the forefoot, you end up putting all the weight on your Achilles tendon. “That’s stress your body has to absorb.”Click to expand...

The Gluteus Medius Activation in Female
Indoor Track Runners is Asymmetrical and
May be Related to Injury Risk
Stephanie E. Nevison, Youngmin Jun, James P. Dickey
Sport Exerc Med Open J. 2015; 1(1):27-34.
Track runners train and compete solely in the counter clockwise direction around the
track. These repetitive motions place track runners at risk of “over-use” injury, but strength
differences place females at greater risk than males. This study was conducted to evaluate the
asymmetry of gluteus medius muscle activation patterns in female runners as they run around
the curves of an unbanked 200 m track. Wireless surface electromyography (EMG) sensors
were adhered to the skin overlaying the gluteus medius. Participants’ muscle activation was
recorded as they ran two 200 m trials at a pace of 5±0.5 m/s and walked 200 m at a chosen
pace. Each participant’s EMG for the running strides was normalized to the average amplitude
of their walking trials. There were significant increases in muscle activation of the outside
(right) gluteus medius when athletes ran on the curves compared to the straightaways (359.1
percent of walking ±132.8 and 324.7±102.6 respectively, p=0.015). There was a trend for decreases
in muscle activation of the inside (left) gluteus medius when athletes ran on the curves
compared to the straightaways (449.2 percent of walking ±136.1 and 469.4±132.6 and respectively,
p=0.065). These data suggest that the gluteus medius abducted the outside (right) leg to
contribute to the lateral forces necessary to run around the curve. The muscular demands for
the two legs are different, and are consistent with observed injury patterns. This loading pClick to expand... -

DOES THE DUMBBELL CARRYING POSITION CHANGE THE MUSCLE ACTIVITY DURING SPLIT SQUATS AND WALKING LUNGES?.
Stastny, Petr; Lehnert, Michal; Zaatar Zaki, Amr Mohamed; Svoboda, Zdenek; Xaverova, Zuzana
Journal of Strength & Conditioning Research: May 08, 2015
The forward walking lunge (WL) and split squat (SSq) are similar exercises that have differences in the eccentric phase, and both can be performed in the ipsilateral or contralateral carrying conditions. This study aimed to determine the effects of dumbbell carrying position on the kinematics and electromyography (EMG) amplitudes of the gluteus medius (Gmed), vastus medialis (VM), vastus lateralis (VL) and biceps femoris during WLs and SSqs.
The resistance-trained (RT) and the non-resistance-trained (NT) groups (both n=14) performed ipsilateral WLs, contralateral WLs, ipsilateral SSqs and contralateral SSqs in a randomized order in a simulated training session. The EMG amplitude, expressed as a percentage of the maximal voluntary isometric contraction (%MVIC), and the kinematics, expressed as the range of motion (ROM) of the hip and knee, were measured during 5RM for both legs.
The repeated measure analyses of variance showed significant differences between the RT and NT group. The NT showed a smaller knee flexion ROM (p<0.001, [eta][superscript digit two]=0.36) during both types of WLs, whereas the RT group showed a higher eccentric Gmed amplitude (p<0. 001, [eta][superscript digit two]=0.46) during all exercises and a higher eccentric VL amplitude (p<0.001, [eta][superscript digit two]=0.63) during contralateral WLs. Further differences were found between contralateral WLs and ipsilateral WLs in both the RT (p<0.001, [eta][superscript digit two]=0.69) and NT groups (p<0.001, [eta][superscript digit two]=0.80), and contralateral WLs resulted in higher eccentric Gmed amplitudes.
Contralateral WLs highly activated the Gmed (90%MVIC); therefore, this exercise can increase the Gmed maximal strength. The ipsilateral loading condition did not increaseClick to expand... -
The relationship of anticipatory gluteus medius activity to pelvic and knee stability in the transition to single leg stance
D. Kim, J. Unger, J.L. Lanovaz, A.R. Oates
PM & R; Article in Press
Background
Knee abduction moment in a weight bearing limb is an important risk factor of conditions such as patellofemoral pain and knee osteoarthritis. Excessive pelvic drop in single leg stance can increase the knee abduction moment. The gluteus medius muscle is crucial to prevent pelvic drop and must be activated in anticipation of the transition from double to single leg stance.
Objective
To examine the relationship of anticipatory activity of the gluteus medius to pelvic drop and knee abduction moment.
Design
Observational, cross-sectional correlational study.
Setting
Research laboratory.
Participants
20 female adults (mean 22.6 years, SD 2.5) were recruited and fully participated. Participant selection was limited to healthy females without a history of knee and ankle ligament injuries; any indication of knee, hip, and/or low back pain; and/or the knowledge of proper squat technique.
Methods
Participants performed 16 single leg mini squats on their non-dominant leg.
Main outcome measures
The onset and magnitude of anticipatory gluteus medius activity were measured in relation to toe-off of the dominant leg during the transition from double to single-leg stance. Pre-planned correlations between anticipatory gluteus medius onset and its activation magnitude, pelvic obliquity, and knee abduction moment were examined.
Results
The magnitude of anticipatory gluteus medius activity was significantly correlated with the knee abduction moment (rs (18) = -.303, p <.001) and pelvic obliquity (rs (18) = .361, p <.001), whereas gluteus medius onset was not significantly correlated with either knee abduction moment or pelvic obliquity.
Conclusions
The amount of gluteus medius activity is more important for controlling knee and pelvic stability in the frontal plane than the onset of activation.Click to expand... -

Evidence of altered corticomotor excitability following targeted activation of gluteus maximus training in healthy individuals.
Fisher BE, Southam AC, Kuo YL, Lee YY, Powers CM.
Neuroreport. 2016 Mar 15
It has been proposed that strengthening and skill training of gluteus maximus (GM) may be beneficial in treating various knee injuries. Given the redundancy of the hip musculature and the small representational area of GM in the primary motor cortex (M1), learning to activate this muscle before prescribing strength exercises and modifying movement strategy would appear to be important. This study aimed to determine whether a short-term activation training program targeting the GM results in neuroplastic changes in M1. Using transcranial magnetic stimulation, motor evoked potentials (MEPs) were obtained in 12 healthy individuals at different stimulation intensities while they performed a double-leg bridge. Participants then completed a home exercise program for ∼1 h/day for 6 days that consisted of a single exercise designed to selectively target the GM. Baseline and post-training input-output curves (IOCs) were generated by graphing average MEP amplitudes and cortical silent period durations against corresponding stimulation intensities. Following the GM activation training, the linear slope of both the MEP IOC and cortical silent period IOC increased significantly. Short-term GM activation training resulted in a significant increase in corticomotor excitability as well as changes in inhibitory processes of the GM. We propose that the observed corticomotor plasticity will enable better utilization of the GM in the more advanced stages of a rehabilitation/training program.Click to expand... -

Lower-Limb Muscle-Activation Patterns During Off-Axis Elliptical Compared With Conventional Gluteal-Muscle-Strengthening Exercises.
Lin CY et al
J Sport Rehabil. 2016 May;25(2):164-172.
CONTEXT:
Gluteal-muscle strength has been identified as an important component of injury prevention and rehabilitation in several common knee injuries. However, many conventionally prescribed gluteal-strengthening exercises are not performed during dynamic weight-bearing activities, which is when most injuries occur.
OBJECTIVES:
To compare lower-limb muscle-activation patterns between conventional gluteal-strengthening exercises and off-axis elliptical exercises with motorized foot-plate perturbations designed to activate gluteal muscles during dynamic exercise.
EVIDENCE ACQUISITION:
Twelve healthy volunteers (26.1 ? 4.7 y) participated in the study. They performed 3 conventional exercises (single-leg squat, forward lunge, and clamshell) and 3 elliptical exercises (regular, while resisting an adduction force, and while resisting an internal-rotation torque). Gluteus medius (GMed) and maximus (GMax), quadriceps, hamstrings, and gastrocnemius muscle activations during each exercise were recorded using surface electromyography (EMG) and normalized to maximal voluntary isometric contraction (MVIC).
EVIDENCE SYNTHESIS:
Normalized GMed EMG was the highest during the adduction-resistance elliptical exercise (22.4% ? 14.8% MVIC), significantly greater than forward lunge (8.2% ? 3.8% MVIC) and regular elliptical (6.4% ? 2.5% MVIC) and similar to clamshell (19.1% ? 8.8% MVIC) and single-leg squat (18.4% ? 7.9% MVIC). Normalized GMax EMG during adduction-resistance (11.1% ? 7.6% MVIC) and internal-rotation-resistance elliptical (7.4% ? 3.8% MVIC) was significantly greater than regular elliptical (4.4% ? 2.4% MVIC) and was similar to conventional exercises. The single-leg squat required more muscle activation from the quadriceps and gastrocnemius than the elliptical exercises.
CONCLUSIONS:
Off-axis elliptical exercise while resisting an adduction force or internal-rotation torque activates gluteal muscles dynamically while avoiding excessive quadriceps activation during a functional weight-bearing activity compared with conventional gluteal-strengthening exercises.Click to expand... -
Running Related Gluteus Medius Function in Health and Injury: A Systematic Review with Meta-analysis
Adam Semciw et al
Journal of Electromyography and Kinesiology; 17 June 2016
Running is a popular sport and recreational physical activity worldwide. Musculoskeletal injuries in runners are common and may be attributed to the inability to control pelvic equilibrium in the coronal plane. This lack of pelvic control in the frontal plane can stem from dysfunction of the gluteus medius. The aim of this systematic review was therefore to: (i) compile evidence of the activity profile of gluteus medius when running; (ii) identify how gluteus medius activity (electromyography) varies with speed, cadence and gender when running; (iii) compare gluteus medius activity in injured runners to matched controls. Seven electronic databases were search from their earliest date until March 2015. Thirteen studies met our eligibility criteria. The activity profile was mono-phasic with a peak during initial loading (four studies). Gluteus medius amplitude increases with running speed; this is most evident in females. The muscles? activity has been recorded in injured runners with Achilles tendinopathy (two studies) and patellofemoral pain syndrome (three studies). The strongest evidence indicates a moderate and significant reduction in gluteus medius duration of activity when running in people with patellofemoral pain syndrome. This dysfunction can potentially be mediated with running retraining strategies.Click to expand... -
A Systematic Review of Rehabilitation Exercises to Progressively Load Gluteus Medius
Jay R. Ebert et al
JSR; In Press
Context: Gluteus medius rehabilitation is of critical importance given its role in pelvic and lower limb stability, and the known link between gluteus medius weakness and many lower limb conditions.
Objective: To systematically review the literature and present an evidence-based graduated series of exercises to progressively load gluteus medius.
Evidence Acquisition: A systematic literature search was conducted in January 2016 to identify studies reporting gluteus medius muscle activity as a percentage of maximal volitional isometric contraction (%MVIC), during rehabilitation exercises. Studies that investigated injury free participants were included. No restrictions were placed on the type or mode of exercise, though exercises that could not be accurately replicated or performed within an independent setting were excluded. Studies that did not normalize electromyographic activity to a side lying MVIC were excluded. Exercises were stratified based on exercise type and %MVIC: low (0?20%), moderate (21?40%), high (41?60%) and very high (˃61%). Evidence Synthesis: Twenty studies were included in this review, reporting outcomes in 33 exercises (and a range of variations of the same exercise). Prone, quadruped and bilateral bridge exercises generally produced low or moderate load. Specific hip abduction/rotation exercises were reported as moderate, high or very high load. Unilateral stance exercises in the presence of contralateral limb movement were often high or very high load activities, whilst high variability existed across a range of functional weight bearing exercises.
Conclusions: This review outlined a series of exercises commonly employed in a rehabilitation setting, stratified based on exercise type and the magnitude of gluteus medius muscular activation. This will assist clinicians in tailoring gluteus medius loading regimens to patients, from the early post-operative through to later stages of rehabilitation.Click to expand... -

Gluteus Maximus and Hamstring Activation During Selected Weight-Bearing Resistance Exercises.
McCurdy, Kevin; Walker, John; Yuen, Derrick
Journal of Strength & Conditioning Research: October 20, 2017
The purpose of this study was to compare the gluteus maximus (GM) and hamstring group (HG) electromyographic (EMG) activation levels among selected weight-bearing resistance exercises. Eighteen young adult females with previous resistance training experience completed the study. Strength was assessed on the bilateral squat (BS) (3 repetition maximum [RM]), modified single-leg squat (MSLS) (3RM), and stiff-leg deadlift (SLDL) (8RM) to determine an 8RM load for all lifts. Surface EMG was collected after 48 hours of rest using wireless Trigno IM Sensors using EMMA software (Delsys), which also collected and synchronized 3D hip and knee motion. A maximum voluntary isometric contraction was determined for the GM and HG to normalize the EMG data. During EMG data collection, 3 repetitions were completed using an 8RM load on all 3 exercises. Gluteus maximus EMG was significantly greater than HG EMG on the BS (40.3 vs. 24.4%, p < 0.001), MSLS (65.6 vs. 40.1 %, p < 0.012), and SLDL (40.5 vs. 29.9 %, p < 0.047). The MSLS produced significantly greater HG EMG (p = 0.001) compared with the SLDL, whereas the SLDL was significantly greater (p = 0.004) than the BS. The MSLS GM EMG was also significantly greater (p < 0.001) than the SLDL and BS, whereas no difference was found between the SLDL and BS. Comparing the activation of the 2 muscle groups in all exercises, the GM seems to be the primary muscle recruited whereas the MSLS seems to produce greater GM and HG activation. The data indicate that it would be most beneficial to include the MSLS during GM and HG training.Click to expand... -

Gluteal Muscle Inhibition: Consequences of Patellofemoral Pain?
Neal R.GlavianoDavid M.Bazett-JonesGrantNorte
Medical Hypotheses; 27 February 2019
Muscle weakness is a common impairment in females with patellofemoral pain (PFP), clinically seen in both the quadriceps and gluteal muscles. These weaknesses have been suggested to result in poor movement patterns, which results in the clinical presentation of pain due to increased stress on the patellofemoral joint. While quadriceps weakness have been identified as a risk factor for the development of PFP, prospective studies have not found gluteal muscle weakness to be a risk factor. Therefore, gluteal muscle weakness may in fact be a consequence of PFP. This muscle weakness is often combated with traditional strengthening programs. These interventions improve both short-term subjective function and improve strength, yet their relationship to long-term outcomes are less than optimal. Strength training of the gluteals also does not transition to improved movement patterns in this population. The presence of hip muscle inhibition may be the explanation for both poor long-term function and altered movement patterns. Assessment methods for muscle inhibition have been studied in the quadriceps, commonly conducted with the superimposed burst technique to calculate an activation ratio. The use of this method may be used on the gluteus medius and gluteus maximus muscles to determine if inhibition of the hip musculature is present in females with PFP. This knowledge would provide clinicians with a more complete picture of muscle dysfunction and lead to a paradigm shift in clinical treatment strategies for this chronic condition. We hypothesize that muscle inhibition is present in the gluteal muscles of females with PFP compared to healthy controls and it is associated with both decreased subjective function and longer duration of symptoms.Click to expand...
