“…19,20 Children are more susceptible to overuse injuries than adults due to the effect on their immature growth cartilages and as children become more heavily involved in cricket. 21 LBP is not associated with impaired hamstring flexibility, stiffness 22 or hamstring muscle length. 23 Massoud Arab et al, 24 further described that there is no significant difference in hamstring muscle length with and without sacroiliac joint dysfunction.…”

Background: Cricket fast bowlers are identified as the players with a higher risk of injury due to their susceptibility to develop low back pain (LBP). Aims and Objective: This study aims to investigate how intrinsic factors associate with LBP among fast bowlers aged between 15-19 years in Colombo division 1 boys’ schools in Sri Lanka. Materials and Methods: A descriptive cross-sectional study was conducted with one hundred and two (102) fast bowlers who were prospectively monitored over the competition period of 2019 cricket season and the demographic data, severity of LBP, general characteristics and intrinsic factors related data were recorded. Results: Thirty-seven (43.5%) of the subjects were presented with LBP. Reduction of quadriceps strength of dominant side, hamstring strength of non-dominant side and increased ankle dorsiflexion of non-dominant side were found to be significantly associated with non-contact LBP (P<0.05). There were significant differences for the quadriceps strength of dominant side and hamstring strength and ankle dorsiflexion of non-dominant side between the fast bowlers with and without LBP. Conclusion: The results concluded that reduced quadriceps muscle strength of dominant side, reduced hamstring muscle strength and higher ankle dorsiflexion of non-dominant side have an important role in predisposing a fast bowler to have an increase in non-contact LBP.

Objective: Cricket fast bowlers are identified as the greatest injury risk players who are more prone to sustain with low back pain (LBP). The current study was aimed to investigate how intrinsic factors associate with LBP among fast bowlers aged between 15-19 years. A descriptive cross-sectional study was conducted with one hundred and two (102) fast bowlers in Colombo division 1 boys’ schools in Sri Lanka. Bowlers were prospectively monitored over the competition period of 2019 cricket season and the demographic data, severity of LBP, general characteristics and intrinsic factors related data were recorded.Results: Thirty-seven (43.5%) of the subjects were presented with LBP. Reduction of quadriceps strength of dominant side, hamstring strength of non-dominant side and increased ankle dorsiflexion of non-dominant side were found to be significantly associated with non-contact LBP (P<0.05). There were significant differences for the quadriceps strength of dominant side and hamstring strength and ankle dorsiflexion of non-dominant side between the fast bowlers with and without LBP. The results indicated that reduced quadriceps muscle strength of dominant side, reduced hamstring muscle strength and high ankle dorsiflexion of non-dominant side have an important role in predisposing a fast bowler to have an increase in non-contact LBP.

“…The studies’ methodological quality was assessed using the modified McMaster Critical Review Form for Quantitative Studies [ 15 ], where a total score ranges from 0 to 16. This critical appraisal tool was selected given that: (1) it has acceptable inter-examiner reliability as reported in several studies [ 15 , 16 , 17 ], (2) most of the 16 points are covered in the CONSORT statement and were considered comprehensive, (3) it can be used for not only RCTs but also cross-sectional studies, and (4) a threshold of poor quality has been used in previous studies [ 15 , 16 , 17 ]. The present study followed the modified guidelines for the critical appraisal tool established in a previous study to enhance inter-examiner agreement [ 15 ].…”

“…Studies with a score of ≤8 in the modified McMaster Critical Review Form for Quantitative Studies (poor quality) were excluded from data synthesis. A threshold of 8 was selected based on previous studies [ 15 , 16 , 17 , 18 ] and was considered reasonable given that it is the middle point of the whole scale.…”

“…No upgrading was present when downgrading was performed in any of the five criteria [ 21 ]. The following criteria utilized in previous studies [ 15 , 16 , 17 ] were used for downgrading: (1) imprecision where meta-analysis included <200 participants in each arm (one level) or <100 participants in each arm (two levels) [ 22 ], (2) inconsistency where the I 2 value for heterogeneity was more than 75% [ 22 ], and (3) indirectness where clinically different populations or outcome measures or indirect comparisons were included in the meta-analysis. Downgrading by two levels was used for conservative consideration when any of the three criteria were satisfied [ 23 ].…”

This systematic review and meta-analysis investigated whether the use of a lumbar roll reduced forward head posture (FHP) while sitting among individuals with or without musculoskeletal disorders. EMBASE, MEDLINE, and the Cochrane Library were systematically searched from their inception to August 2020. The quality of evidence for variables used in the meta-analysis was determined using the GRADE system. Five studies satisfied the criteria for data analysis. All studies included individuals without any spinal symptoms. Data from five studies on neck angle showed a statistically significant (p = 0.02) overall effect (standardized mean difference (SMD) = 0.77), indicating a lesser neck flexion angle while sitting with a lumbar roll than without it. Data from two studies on head angle showed a statistically significant (p = 0.04) overall effect (SMD = 0.47), indicating a lesser head extension angle while sitting with a lumbar roll than without it. In each meta-analysis, the quality of evidence was very low in the GRADE system. The use of a lumbar roll while sitting reduced FHP among individuals without spinal symptoms.
