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.
DESIGN: A qualitative and quantitative research study.
METHODS: This study involved fourth-year medical undergraduates during their clinical posting in ophthalmology. One PAL session was conducted in each of the 4-week clinical postings. Peer tutors were selected during the first week and were briefed on PAL. Premultiple and postmultiple choice questions were distributed to PLs before and after each PAL session. One focus group discussion was conducted with PLs to explore their perception. Peer tutors were requested to give feedback in the form of structured Likert scale statements with 2 open-ended questions.
RESULTS: A total of 104 students, 6 PTs and 98 PLs, participated in this study. Both tutor and learner groups expressed positive attitudes toward PAL. Peer learners preferred having PAL in a clinical setting. There were some issues related with PAL that emerged from both groups. Success in PAL depends on the teaching ability of PTs.
CONCLUSIONS: Students have positive perceptions toward PAL. Most of the students believed PAL was beneficial to them.
