“…Two studies found a negative correlation, moderate [ 25 ] or weak [ 26 ], between hip extensor strength and DKV during a single-leg squat test. Conversely, no significant correlations were found in other studies between the two variables during step-down tests [ 22 ], single-leg squat tests [ 27 ], or forward lunges [ 28 ].…”

“…The relationship between the DKV and the strength of hip abductors and/or hip external rotators was investigated in all of the included studies and/or hip extensors in five studies [ 22 , 25 , 26 , 27 , 28 ]. The main outcome measures of the included studies, including the reported correlation between hip muscle strength and DKV, are shown in Table 3 .…”

“…However, another two studies revealed a weak positive correlation between hip abductor strength and DKV when participants performed single-limb step-down [ 23 ] or single-leg squat [ 26 ] tests. Furthermore, other studies found no statistically significant correlations during a single-leg squat test [ 24 , 28 ], a single-leg drop [ 28 ], or a forward lunge [ 27 ].…”

“…Two studies showed a weak positive correlation between hip external rotators and DKV in female participants during a single-leg squat test [ 24 , 26 ]. However, no relationship between these parameters was observed in cohorts comprising both males and females [ 25 , 27 , 28 ] or in cohorts that were exclusively females [ 22 , 23 ].…”

“…All included studies recruited healthy participants (Table 2). Five studies used handheld dynamometry (HHD) [22,23,26,27,29], one study used a Biodex System 3 Pro (Biodex Medical Systems, Inc., Shirley, New York, NY, USA) [28], and one study used a Biodex Isokinetic Dynamometer (Biodex Medical System, Inc., Shirley, New York, NY, USA) [25] to measure hip strength. All studies measured the isometric peak torque and normalized strength against the participant's body mass.…”

This study aimed to systematically review research investigating the association between hip muscle strength and dynamic knee valgus (DKV). Four databases (MEDLINE, PubMed, CINAHL, and SPORTDiscus) were searched for journal articles published from inception to October 2020. Seven studies investigating the association between hip muscle strength and DKV using a two-dimensional motion analysis system in healthy adults were included. The relationship between hip abductor muscle strength and DKV was negatively correlated in two studies, positively correlated in two studies, and not correlated in three studies. The DKV was associated with reduced hip extensor muscle strength in two studies and reduced hip external rotator muscle strength in two studies, while no correlation was found in three and five studies for each muscle group, respectively. The relationship between hip muscle strength, including abductors, extensors, and external rotators and DKV is conflicting. Considering the current literature limitations and variable methodological approaches used among studies, the clinical relevance of such findings should be interpreted cautiously. Therefore, future studies are recommended to measure the eccentric strength of hip muscles, resembling muscular movement during landing. Furthermore, high-demand and sufficiently challenging functional tasks revealing lower limb kinematic differences, such as cutting and jumping tasks, are recommended for measuring the DKV.

Background: Lack of control in deep muscles may result into poor segmental support even during activities of daily living in people with or without history of low back pain. This states the importance of muscular system in control of spinal stability. Aim: To evaluate and estimate core strength of lumbar region in normal individuals. Methods and Material: Cross sectional observational study with convenience sampling was carried out on 843 normal healthy individuals between the age group of 18 – 60 years. Core strength was estimated by pressure biofeedback unit with individual in prone formal test to assess transversus abdominis. Pressure reduction which was held at least up to 10 seconds was noted. The same procedure was repeated for three times and the best of the three repetitions was used for analysis. Statistical analysis: MedCalc version 19.7.4 was used. Reference ranges were calculated with 90% CI with non-parametric percentile method. Results: Reference range was 2 – 10 mmHg with median 9 mmHg for all the subjects between the age group of 18-60 years. Reference range for males (5 – 10 mmHg) was higher than females (2 – 10 mmHg) among this age group. Median for males and females was 10 mmHg and 6 mmHg respectively. Reference ranges was 5 – 10 mmHg for 18 – 30 years, 2 – 10 mmHg for 31 – 40 years and 41 – 50 years respectively and 2 – 9 mmHg for 51 – 60 years age groups. Conclusions: Reference range for the core strength of lumbar region among normal individuals as measured by pressure biofeedback unit is 2 – 10 mmHg. Key words: Core strength, Pressure biofeedback unit, Reference range, Transversus abdominis
