Lower Extremity Motor Coordination Test (LEMOCOT)
Introduction:[edit | edit source]
Lower Extremity Motor Coordination Test was developed as an easy, yet effective tool to clinically assess, measure, and evaluate the deficits in Lower Limb Motor Coordination [1] in conditions such as stroke, spinal cord injuries, ataxia, Parkinson’s disease, schizophrenia or other psychiatric illnesses.
The standard reference values were determined using healthy individuals, categorizing them into age and gender. [1]
It is able to detect motor coordination disturbances after stroke. It also gives a strong indicator of participation capabilities. [1]
It is interesting to note that LEMOCOT scores differentiated between stroke patients who were discharged to long-term care compared to other types of living environments. [1]
Technique:[edit | edit source]
The patient, in a comfortable sitting position, with heels on the proximal target and with the knees at 90° of flexion, is instructed to alternately move his/her lower limb as quickly as possible and touch with the hallux two red targets with 6 cm in diameter (one proximal and one distal), separated by a distance of 30 cm for 20 seconds. An additional instruction is given not to sacrifice the accuracy of the touches nor the quality of the movement to increase speed. A familiarization trial is conducted first before the examiner counts the number of touched targets.[1][2]
Obtaining the LEMOCOT Score[edit | edit source]
There are a few possible ways to determine the LEMOCOT score, as illustrated by different researchers.
Validity and Reliability:[edit | edit source]
The convergent construct validity was shown by significantly high correlations with physical and functional tests, and the divergent validity was shown by a reduced association with cognitive or visual perceptual tests.
Evidence:[edit | edit source]
Test-retest reliability in stroke population[edit | edit source]
Intraclass correlation (ICC) >0.97
Construct validity p<0.0001
ICC values (dominant and non-dominant limbs) 0.90<ICC<0.99[1]
Validity and Reliability in Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) population[edit | edit source]
ICC 0.92 - 0.97[4]
Normative Values for LEMOCOT[5]
