OSCE Research papers

Snider et al. 2011

• Cross sectional study

I/C:

• Measured palp. accuracy of lumbar SP’s using bony landmarks (Vs xray)

O:

• 69% accuracy of spinal level

• Identification rate of SP’s significantly higher using multiple bony landmarks than with fewer.

Limitations:

• Only 3 clinicians

• No standardised ruleset for palpation order

• Some anomalies with 12th rib placements caused lower accuracy on certain subjects.

You have been asked to locate a process on the spine - SP, TP, lamina etc.

• What paper may you cite?

• Give background info on the paper and how it supports your answer

• Limitations?

Park et al. 2013

• Psoas + QL activation inhealthy vs LBP population

P:

• Cross sectional study

I/C:

• Measured EMG scores druing iso. trunk efforts

• LBP participants with low ES EMG had greater bias of Psoas major (both parts) + QL during trunk extension

O:

• LBP participants with a High ES EMG showed less PM activity during extension.

• Hypothesized this is to “splint” the region and protect it in movement given individual anatomy.

Limitations:

• Small sample size

• Only those with history of LBP, none with current LBP

You are tasked with a movement / palpation of muscles around the lumbar spine:

Grimaldi et al. 2009

• Cross sectional Comparative

I/C:

• MRI used to measure muscle mass of glute med, min and piri. in mid and advanced hip pathologies vs control

O:

• Muscle volume smaller around hip of those with advanced condition, no difference found between mild and control. 12-15% decrease in advanced case. Up to 15% increases in affected side in mild cases. Hypertrophy in early stages

Limitations:

• Small sample size

You are asked to palpate a structure of the hip/ anything working alongside glutes:

Goderecci et al. 2022

P:

- Retired semi pro rugby players

I/C:

• Self reported function + history of injury

O:

• prev injury =  retired earlier = worse function + mental health

• Prevention = NB - without injury knee health normal

Limitations:

• Male only

• Elite sportspeople only

• Self reported history and function

Knee structures - any key structure in knee linked to injury:

Delahunt and Remus 2019

Risk factors for LAS + CAI

Intrinsic:

Risk factors:

• History of previous ankle sprain 40%+ in CAI Poor ankle + hip extensor strength Poor Balance

Extrinsic RF's:

• Court based sports (Basketball)

Lateral Ankle Paper

McKeon et al. 2014

O:

• Intrinsic muscles = local stabilisers → maintain arch;

• extrinsics = global movers → modulate load.

• Dynamic control > passive structures.

• Weak intrinsics linked to common injuries (PF, PTTD, MTSS).

Limitations:

• Conceptual model only, limited EMG evidence, no RCTs

• Review Article

Sternad et al. 2018

• Review Article

O:

• Variability in movement is normal + functional - not error. Multiple ways to move functionally - individuals develop their own (based on anthropometry + prev. injuries + neurom. control)

Limitations:

• Review Article

Mathiassen et al. 2006

• Review Article

O:

• Variations in movement normal to avoid repetitive stain injuries. In similar small movements injuries may develop, therefore body attempts to vary it’s actions to recruit different fibres, leading to variation not only across individuals, but between an individuals own steps.
