Not exact matches
Recent research on hip strengthening exercises
has shown a direct link between hip
weakness and these three muscles — the gluteus
medius, the gluteus maximus, and the tensor fascia lata (TFL).
Excessive knee valgus
has been linked to gluteus
medius weakness, by way of reduced hip abduction strength (Jacobs et al. 2007; see review by Cashman, 2012).
However, when comparing individuals with and without low back pain, it
has been noted that there is hip abduction
weakness in those with pre-existing low back pain compared to healthy controls and that this is accompanied by greater gluteus
medius co-activation during single leg stance.
Gluteus
medius weakness, by reference to low hip abduction strength,
has been linked to patellofemoral pain in cross-sectional case - control studies (Ireland et al. 2003; Prins et al. 2009; Souza and Powers, 2009; Lankhorst et al. 2012).
These findings indicate that addressing gluteus
medius weakness may well
have some benefit for patellofemoral pain.
Hip osteoarthritis
has been associated with reduced hip abduction strength, which is indicative of gluteus
medius weakness (Arokoski et al. 2002; Rasch et al. 2007; Suetta et al. 2007) as well as with compensatory increased gluteus
medius muscle activity (Sims et al. 2002; Dwyer et al. 2013).
Some researchers
have suggested that gluteus
medius weakness, leading to overactivity, might be implicated in the development of low back pain.
