Aj and Slrt muscle fibers were then manipulated into the culture dishes on opposite sides of the neuron and plated within 50-100 [micro]m of the cell body.
For example, spikes in B19 evoke EJPs in muscle fibers of the supralateral radular tensor (Slrt) muscle (Fig.
In this way, each motoneuron (e.g., B19) is responsible for the excitation and contraction of hundreds of individual cells within the fiber bundles of specific muscle groups (e.g., the Slrt).
As originally described by Kater, and as seen in Figures 1 and 2, one of the muscle targets of B19 is the Slrt muscle group.
Neuron B110 was connected to each of the muscle groups tested (the Imrt was not examined), but its synaptic coverage of the Slrt muscle group was less extensive than its connectivity to the Aj muscle group (Fig.
This functional reinnervation was initiated at the point of entry of the growing axon into the fanlike muscle group, with all other Slrt muscles lacking evoked EJPs on that day (Fig.
Interestingly, mEJPs are extremely rare in adult Slrt muscle fibers, but were detected in greater than 80% of muscle fibers after 3-5 days of buccal nerve regeneration (Fig.
In 32(64%) patients Straight Leg Raising Test (SLRT
) was less than 45 degrees and in 18 (36%) patients it was more than 45 degrees out of the total fifty patients.
Good: Pain: Occasional, infrequent, mild in nature, tolerable and does not repeat with activities causing pain, SLRT: Able to perform SLRT upto 60-70 degrees without any pain, Neurological assessment: Marked neurological recovery, power of muscles recovered to near normal and patient not experiencing any subjective loss of sensation, Spinal movements: Terminal restrictions of movement but painless, Returned to job and performs satisfactorily but avoids extreme spinal movements and careful with regard of lifting weight, Subjective analysis: Patient is satisfied with regard to relief of symptoms during working and daily living activities, ODI score: Patient with ODI score more than 16 and less than 20.
Fair: Pain: Partial recovery of pain but notices pain on strenuous work, SLRT: Patient can perform SLRT between 50 to 70 degrees with little difficulty, Neurological assessment: Minimal improvement both motor and sensory, Spinal movements: Movements restricted and painful in terminal degrees, Patient resuming to light job which does not involve extreme spine movements and lifting weight., Subjective analysis: Partially satisfied, ODI score: Patient with ODI score more than 20 and less than 24.
Poor: Pain: Unrelieved/persisting/worsening, SLRT: Restricted to pre-surgical status, Neurological assessment: No signs of recovery/worsening, Spinal movements: Gross restriction and painful, Unable to get back to his/her pre-illness job, Subjective analysis: Unhappy, ODI score: Patient with ODI score with more than 24.
The study revealed that majority (90 percent) of the patients had positive SLRT
