Repeated trials of this exercise can fatigue the intrinsic muscles
They reported that the patient's paresthesia symptoms disappeared following neurolysis of both the ulnar and the median nerve, while atrophy of the intrinsic muscles
There is increasing calcification and ossification of laryngeal cartilages, atrophy of intrinsic muscles
, and degenerative changes in the joints.
Physical examination of upper limbs was normal except mild atrophy of left hand intrinsic muscles
and right Hoffmann's sign.
Patients may report difficulty with motor tasks involving grip and pinch strength or fatigue with prolonged action of the intrinsic muscles
MGA may lead to misdiagnosis of conditions affecting the nerve supply to the upper extremity, particularly intrinsic muscles
They use intrinsic muscles

Power was Medical Research Council (MRC) grade 5 in the deltoid, biceps, and triceps muscles but MRC grade 4 in the right and left wrist flexors and extensors and intrinsic muscles
of the hand.
Strengthening these intrinsic muscles
can increase joint stability and improve shock absorption.
11 These changes have been studied widely in large muscle groups such as the quadriceps but a very less emphasis has been given to investigate changes occurring in other peripheral muscles especially the muscles of the upper extremity such as wrist and intrinsic muscles
of the hand.
For example, it's good to use soft surfaces like sand or grass to exercise those intrinsic muscles
There is motor function to peroneus longus, a plantar-flexed first ray, but less power to the intrinsic muscles
that extend the toes.
