I was asked to carry out a neurological assessment of a 47 year old male. He had an atrioventricular malformation (AVM), which may have been a contributing factor to the spontaneous bleed which he presented with. Although he had a brain injury, his presentation was much like a stroke. He had right sided weakness of upper and lower limbs and he also had a dysphasic presentation and was unable to communicate verbally (3 in verbal section of GCS). My supervisor chose this patient as it would also be a good opportunity to be able to feel tone and get a better understanding of what is normal/abnormal tone. The focus of this first assessment was therefore looking mainly and tone and motor control.
Task:
To conduct a thorough neurological assessment with specific emphasis on the assessment of tone and motor control.
Action:
To start the assessment I introduced myself to the patient. I then checked the obs chart and medications list. I first asked the patient to do some gross movements with both arms and legs to get a general idea of his level of understanding as well as his ability to follow commands. This also gave me a good indication of the level of impairment of his right side. I then proceeded to assess the patients tone. I looked at his unaffected side first and started distally, looking at his fingers, wrist, elbow then shoulder. I then compared this to his affected side again starting distally. The last part of the assessment included a quick chest check and a look at his current mobility.
Results:
All obs were within normal limits. The patient had voluntary control and full range of motion with the left upper and lower limb. Looking at the tone of the unaffected side, all joints had a certain level of resting tone/ slight resistance with movement. The affected side however had no resistance with passive movement. The upper limb was completely flaccid and there was no real end feel at the end of range. No voluntary movement of the upper limb was observed on the right side. The right leg also had low tone but slight dorsiflexion was achieved.
Evaluation:
I think to improve my assessment of tone, I need to address my hand positioning skills. This is crucial in being able to perform the technique correctly and to feel any abnormalities. It also is important in terms of safety especially when doing quick stretches. As this patient has low tone, hand positioning and safety would be especially important as his joints are at risk of damage if inappropriate forces are applied to these areas of risk.
Strategies:
To improve my assessment of tone, I need to practise handling on family and friends. By practising on people with normal tone, I will be able to perfect my hand position for both the slow stretch and the quick stretch. Another strategy would be to try and continue assessing this patients tone to see if I can pick up any change in the level of tone.
