METHODS: In this study, twenty formalin embalmed human cadavers were used and we have documented the orientation of the PTLF and quantified the number of peripheral nerve endings at the different vertebral levels.
RESULTS: Mean distance of PTLF from vertebral spines to the musculofascial junction was at thoracic region 3.38cm and 3.34cm; at lumbar region, it was 7.4cm and 7.36cm and at sacral region it was 2.98cm and 2.96cm on right and left side, respectively. The angulation of PTLF varies from 18-110 degrees at different vertebral levels. The microscopic data shows the thickness of PTLF and number of nerve endings in the sacral level is increased compared to that of thoracic vertebral levels.
CONCLUSIONS: We have contributed the novel morphological and microscopical details to the limited existing data on PTLF. We also have provided the quantitative data of nerve fibers, which are possible nociceptors of PTLF.
OBJECTIVE: The objective was to review the evidence on the effect of core exercises on clinical and functional outcomes after TKA in individuals with knee osteoarthritis (OA).
METHODS: PubMed, Scopus, CINAHL, Web of Science, the Cochrane Library, and ProQuest databases were explored with appropriate keywords for studies published on the effect of core exercises on TKA from inception to 1 April 2024. Two authors independently screened the titles and abstracts and full-texts, and a third author solved the discrepancies. Risk of bias assessment was done with the Joanna Briggs Critical Appraisal tool. The final articles were systematically summarised.
RESULTS: A total of 1485 records were retrieved. Sixty-four articles were included for screening full-texts, and four articles were ultimately included. Core exercises were administered for three to 6 weeks. The administration of core exercises along with the standard knee rehabilitation programme significantly improved balance, mobility, knee function, transverse abdominis muscle thickness, transversus abdominis contraction, and quality of life after TKA (p
METHODS: We searched six databases (PubMed, Scopus, Web of Science, CINAHL, EMBASE, and ProQuest) using appropriate search terms to identify the relevant literature published on the factors determining QoL following TKA. Two reviewers independently performed the study screening and study selection. A third reviewer was consulted in case of any disagreement. The methodological quality of the included studies was assessed using the Modified Downs and Black Index checklist. This review was registered in PROSPERO (CRD42022352887) and reported according to the PRISMA checklist.
RESULTS: We identified a total of 8517 studies, 29 of which were included. Advanced age; female sex; increased body mass index (BMI); the presence of comorbidities such as diabetes; contralateral knee pain; poor preoperative status; psychological and pain-related factors such as the presence of pain catastrophizing; central sensitization; kinesiophobia; anxiety; depression; chronic pain; psychological distress; low level of optimism; and reduced patient satisfaction were used to determine post-TKA QoL scores. High BMI and depression were the most common factors evaluated in these studies. Overall, the methodological quality of the included studies varied from high to low.
CONCLUSION: After TKA, the overall QoL score improved. However, there are a few physical, behavioral, and psychological factors that influence QoL. Identifying these factors could aid clinicians and health professionals in treating and rehabilitating patients by helping them improve patient prognosis after TKA.
