Intrinsic Muscles

A clinical and electromyographic study of major nerve transections at the wrist in 22 patients has shown that electrical recovery nearly always occurs in the intrinsic muscles, despite the absence of clinically detectable function. There appears to be a level of electrical reinnervation above which clinically detectable intrinsic muscle power is usually present. This level would appear to be 50% of the contralateral maximum evoked muscle action potential; above this the “myth” of clinical recovery becomes a reality.

The reciprocal interaction between the accommodation and pupil control systems of the human eye is examined from a theoretical point of view. The system, which is responsible for maintaining pupil diameter at a value which is a compromise between conflicting requirements, is represented by a control model, and is considered in terms of the concept of a performance index.

We report a series of 12 patients (19 hands) with clasped thumb who underwent surgical treatment. The series is divided into three groups. In the first group, the prominent pathological feature was hypoplasia of the extensor tendons which was treated by tendon transfer. The second group, the arthrogryphotic type, had contracture of the intrinsic muscles of the thumb and shortening of the skin; these needed mainly release operations. In only three hands out of nine was tendon transfer performed. The third group was defined by a combination of skeletal, muscular and tendon hypoplasia. Instability of the M.P. joint and adduction contracture of the first ray were found in all hands of this group. The adduction deformity was corrected by skin-plasty of the first web and the extension was improved by tendon transfers. Only one case needed stabilisation of the M.P. joint. The final results were related to the extent of the contractures and to the age of the patient when treatment started.

The purpose of this study was to investigate the strengths of four intrinsic muscles of the hand of college baseball players. The strengths of four intrinsic muscle groups were measured by the Rotterdam Intrinsic Hand Myometer (RIHM) which has been developed to assess the abduction of the little finger and index finger, and palmar abduction and opposition of the thumb. The strengths of these four intrinsic muscle groups were compared between baseball players and inexperienced sports players. The abduction of the little finger and index finger, and the opposition of the thumb in both the dominant and nondominant hands of the baseball players were notably stronger than those of the inexperienced sports players. There was no statistical difference in the strength of the palmar abduction of the thumb between the two groups. The results suggest that the specific intrinsic muscles in both the dominant and nondominant hands might be strengthened by repeated baseball practices, such as a batting performance, which requires strain in both the dominant and nondominant hands repeatedly.

Intrinsic Muscles

1. A short review is given of the coelom and of its morphological relations in the earthworm. 2. The arrangement of the intrinsic muscles in a typical septum is described. Four main sets of muscles are recognized: viz. radial muscles, circular muscles, oblique muscles, and the sphincter around the ventral foramen. 3. It is suggested that the function of the radial, circular and possibly of the oblique muscles is to control bulging of the septa, and so serve to localize differences in pressure in the coelomic fluid. Normally, in active worms, the sphincter of the ventral foramen is contracted and forms an effective barrier to the passage of fluid from one coelomic compartment to the next. This was verified experimentally and by X-ray photography. 4. A series of measurements of the pressure in the coelomic fluid in different regions of active worms was recorded by means of a capillary manometer and by the use of a spoon-gauge apparatus. Manometric measurements showed the average pressure in the anterior third of the body to be 16.0 cm. water and in the tail region to be 8.0 cm. water. The corresponding figures obtained with a spoon gauge were 13.5 and 8.5 cm. water. The pressure in narcotized worms is zero. 5. These results are discussed, and it is pointed out that the manometer readings suffer from the disadvantage of failing to show the rapid fluctuations in pressure which occur during wriggling movements of the worms. 6. It is calculated from these pressure readings that a worm can exert a forward thrust equivalent to forces of between 1.5 and 8.0 g. These figures agree well with those obtained by Gray & Lissman by the use of a special torsion balance. 7. The burrowing movements of earthworms are briefly described. 8. It is shown that the sphincters of the dorsal pores and of the nephridiopores do not normally allow of the escape of coelomic fluid, and will withstand a pressure well outside the normal range.

1. The vocal performance of different species of songbird was compared by measuring the maximum total sound power produced during normal song. This varied from 10 mW/Kg body weight in the linnet Acanthus cannabina and the whitethroat Sylvia communis to 870 mW/Kg in the song-thrush Turdus philomelos. 2. In comparison, the performance of the chicken Gallus domesticus during crowing was approximately 60 mW/Kg. 3. There was some evidence that performance was related to size in the songbirds as a group, the smaller bird being less effective than the larger. 4. Differences in performance are discussed in relation to the presence or absence of intrinsic muscles in the syrinx and to possible effects of scale on the efficiency of the fundamental sound-producing process.

Intrinsic Muscles

The playing of many musical instruments is performed principally by the small intrinsic muscles of the hands. Practice records were reviewed to investigate the epidemiology, etiology, and risk factors for intrinsic muscle strain. Fifty-one instrumentalists were found, out of 129 having strains of all hand and forearm muscles. These 51 comprised 15.5% of all 329 musicians seen for overuse-related conditions. The patient ages ranged from 10 to 72 years; 20 were male. Forty-one of the 51 played keyboard or stringed instruments; 11 of the 19 stringed instruments were bowed. Twenty-one patients were professionals or university/conservatory music students. Sixty percent of strains were caused by playing music, with slightly more than half being in the professional/collegiate cohort. Pianists were more likely to experience right hand involvement. Seven patients had bilateral intrinsic strains. Thirteen experienced concomitant strains of the extrinsic forearm muscles, either on the same side or bilaterally with bilateral intrinsic strains. Treatment followed standard principles, with hand rest prescribed in 12, musical practice changes in 19, activity modification in 30, and formal exercises/hand therapy in 23. Nonsteroidal medication was prescribed in 17 cases. The data suggest that intrinsic muscle strains related to overuse follow the same etiologic and anatomic patterns as other upper extremity muscle strain and pain syndromes and have the same risk factors. Health care providers should be aware of the role of the hand intrinsic muscles in playing musical instruments and their propensity for overuse-related strain syndromes from both musical and nonmusical activities.
