Clinical Presentation

Physical examination may be negative if the patient is seen within hours of the accident. Over time, however, patients develop tenderness in the cervical spine area, as well as decreased range of motion and muscle spasm. Neurological examination of the upper extremity should include assessment of motor function and grip strength, sensation, deep tendon reflexes, and range of motion (especially of the neck and shoulder).

Methodological considerations

The return of fractionated finger movements represents an excellent outcome and is therefore of clinical interest but this does not mean that it is the best paradigm to use, for the reasons described above. An important concept in experimental design is that it is not possible to scan patients in order to determine the neural correlates of something they cannot do (Price and Friston, 1999). An experimenter must find alternative ways to probe the system of interest. An alternative task is dynamic hand grip which is used in several studies described in this chapter (Ward and Frackowiak, 2003 Ward et al., 2003a,b). Hand grip can be performed by patients with even minimal recovery and its performance correlates well with other measures of upper limb recovery (Heller et al., 1987 Sunderland et al., 1989). In order to control as much as possible for the effort involved in performing a hand grip task subjects (controls and patients) can be set target forces that are a fixed percentage...

Cerebral reorganisation in chronic stroke

Thus alternative brain regions appear to be recruited after focal damage in those patients with greatest need. In addition, there is evidence that IL PMd takes on an executive motor role, such that task-related BOLD signal increases linearly as a function of hand grip force in chronic stroke patients with significant impairment, but not in good recov-erers or in controls. Thus it is unlikely that the response to focal injury involves the simple substitution of one cortical region for another, as nodes within a remaining motor network may take on new roles, that is there is true lesion-induced reprogramming in the human central nervous system. The studies discussed so far have been on chronic stroke patients. It appears that the relationship between size of brain activation and outcome in the late post-stroke phase holds true for patients in the early post-stroke phase also, at least when considering the primary and non-primary motor regions discussed above (Ward et al., 2004). Thus...

Management of musculoskeletal impairments

Studies in chronic stroke have demonstrated that a daily or three times per week stimulation program over 3-6 weeks strengthens the stimulated muscles and restores some degree of active and passive range of motion of the mobilized joints (Smith, 1990 Hazlewood et al., 1994 Pandyan et al., 1997 Alon et al., 1998 Powell et al., 1999). More recent clinical trials have combined the NMES with task-specific training of the paretic upper limb (Alon, 2003 Cauraugh and Kim, 2002, 2003a, b, c). Significant improvement in motor control as documented by Fugl-Meyer score or EMG has been reported by a number of investigators (Faghri et al., 1994 Chae et al., 1998 Francisco et al., 1998 Powell et al., 1999 Cauraugh et al., 2000 Cauraugh and Kim, 2002, 2003a, b, c Kimberley et al., 2004). Improved functional ability was limited to improvement in performance speed or increasing number of blocks transferred but not re-learning of hand function or ability lost due to paralysis, however.

Testing Batteries Versus Individualized Testing

Neuropsychological testing batteries provide a structured approach to the assessment of cognitive function. Although there are many neuropsychological testing batteries, two batteries are most commonly used the Halstead-Reitan Battery 18 and the Luria-Nebraska Neuropsychological Battery. y The Halstead-Reitan Battery is a collection of tests that Halstead found to discriminate normal individuals from patients with organic brain disease. The core of the Halstead-Reitan Battery includes six tests developed by the authors (measuring abstract reasoning, tactile performance, tactile visual-spatial memory, rhythm perception and memory, speech-sound perception, and primary motor speed) and seven tests developed by other individuals (measuring intelligence, psychomotor speed, sequencing abilities, language function, sensory function, grip strength, and personality functioning). The entire battery requires at least 6 hours for administration, not including scoring and interpretation, so...

Executive Function and Motor Performance

Hand Dynamometer.y This test measures grip strength in each hand. Patients are given three trials with each hand, the first considered practice. Large differences between left and right grip strength may reflect lateralized hemispheric dysfunction. Adequate norms are available for this test.

Documenting hand function (e.g., range of motion of fingers) after stroke (Jack et al., 2001) The majority of VR-based interventions used to train motor deficits have been used with patients who have had a stroke. Piron et al. (2001) used a virtual environment to train reaching movements, Broeren et al. (2002) used a haptic device for the assessment and training of motor coordination, and Jack et al. (2001) and Merians et al. (2002) have developed a force-feedback glove to improve hand strength and a non-haptic glove to improve the range of motion and speed of hand movement. Based on the results of the latter study, which included three patients

Structural Aspects Of Handedness

Furthermore, there is evidence that the volume of the right hand is greater than that of the left hand (Purves et al., 1994), and the surface area also might be expected to differ. Certainly in my own laboratory we have found the breadth of the right hand to be slightly greater than that of the left. Such size differences might be related to a difference in muscle mass and or bone size (see Steele, 2000) brought about by differential hand use, and might be expected to have cortical correlates. Conceivably, the neuroanatomic and neurophysiological findings are a reflection of this. In this context it is of interest that complexity of dendritic organization in the presumed hand region of the cortex has been related to differences in finger dexterity and hand function characteristic of a person's working life (Scheibel et al., 1990).

Forearm Exercise Testing

Oxidative phosphorylation cannot occur. A simple technique for evaluating lactate production in response to ischemic forearm exercise was described by Munsat in 1970. 6 In that report, rested and fasting individuals squeezed a handheld ergometer, with a workload of 4 to 7 kg-m, at 60 Hz for 1 minute. (Alternative methods are to sustain 1.5-second contractions that are separated by 0.5-second rest periods for 1 full minute M or squeezing a hand dynamometer to 50 percent of maximum grip strength until exhaustion--usually about 10 minutes. 2 ) Although the serum lactate concentrations vary significantly among the studied individuals (the standard deviation approximated 60 percent of the mean), their relative change (rather than their absolute change) is fairly constant for a given individual. The serum lactate concentration peaks within 5 minutes (within 3 minutes for 90 percent of the tested individuals) of work cessation at a value that is three- to five-fold greater than the initial...

To date, findings from studies of the hemiplegic UE suggest a moderate to strong correlation existing between muscle weakness and impaired motor function in patients after stroke (Ng and Shepherd, 2000). Torques measured during hand grip have been correlated with some hand function tests among patients in the acute and sub-acute post-stroke stages (Sunderland et al., 1989). In addition, isometric strength of elbow flexors strongly correlates with functional hand to mouth movements (Bohannon

Directed Neurological Examination Assessment Of Muscle Bulk

More objective measurements can be made with the use of specially designed instruments to measure force. The only one widely used in clinical practice measures grip strength. Recently an electronic strain-gauge that measures maximum isometric force has also been used in clinical research trials for the treatment of amyotrophic lateral sclerosis. y Some degree of objective measurement can also be obtained through formal assessment by a specially trained physical therapist. These semiquantitative methods (semiquantitative because they require the full cooperation of the patient being examined) are not primarily used for diagnostic purposes but rather for measuring changes that occur over time in response to some disease or treatment.

FES for hand grasp and release

Technology for the restoration of hand function in tetraplegic individuals has been under development for over three decades (Billian and Gorman, 1992) and has now entered the clinical environment (Peckham et al., 2001). The objective of the use of FES in hands of tetraplegic individuals is to restore grasp, hold and release, thereby increasing independence in performance of functional tasks. Sixty-one C5 or C6 patients were enrolled. All of the patients had one or more concurrent surgical procedures to augment hand function. A total of 128 cumulative implant years were evaluated. Summary pinch force measurements with and without the neuroprosthesis are shown in Fig. 9.4. Pinch force in both lateral and palmar prehension improved with the neuroprosthesis. The small improvement seen post-operatively with the neuroprosthesis turned off can be attributed to tendon synchronization. All patients realized some improvement in pinch force measurement in at least one grasp pattern with the...

Gamekeepers Thumb

Often the interposition of an adductor aponeuro-sis between the ends of the torn ligament (termed a Stener lesion) prevents ligament healing unless surgery is performed. Early repair of the ligament, within one to two weeks, optimizes return of hand function. If there is tenderness but the MCP joint is stable, a thumb spica splint or cast is applied for two to four weeks and the joint then reassessed for instability.


Infection of a flexor tendon sheath, although an uncommon injury, requires early recognition to prevent serious complications. A position of finger flexion, swelling of the entire finger, and tenderness along the tendon sheath are common findings. The most specific physical finding is severe pain with passive extension of the finger, which leads one strongly to suspect flexor tenosynovitis. In sexually active patients disseminated gonorrhea may also present as tenosyn-ovitis. Emergency orthopedic consultation is suggested for suspected tenosynovitis, as early debridement and aggressive care may allow salvage of the hand, whereas treatment delay of even 24 hours may result in a dramatic loss of finger or hand function.34


The value of NMES to the training of upper limb function remains controversial. Recent studies have begun to test the contribution of NMES particularly to hand function (Cauraugh et al., 2000 Alon et al., 2002 Cauraugh and Kim, 2002, 2003a, b, c Alon and Ring, 2003 Alon et al., 2003 Popovic et al., 2003). Outcome measures used in hand function evaluation vary considerably. Cauraugh and colleagues only use the box and blocks test while others also use the Jebsen-Taylor and the nine-hole peg (Alon and Ring, 2003 Alon et al., 2003 Kimberley et al., 2004). Popovic et al. (2003) recently used a comprehensive test battery that included many ADLs that depend on the upper limb collectively termed upper extremity functioning test (UEFT) as well as hand drawing test and patients testimonial statements regarding reduced upper extremity motor activity long (MAL) tests. that while the gains of hand functions were both statistically and clinically meaningful, the vast majority of patients improve...

Subjective Objective

Myopathy can be a feature of hypothyroidism and manifests with proximal muscle weakness. Regardless of the cause of the hypothyroidism, weakness is observed in about one third of these patients.y Increased muscle size and firmness, which is most obvious in the limb musculature, as well as slowed muscle contraction are important features to identify. Exertional pain, stiffness, and cramps may be noted, and myoedema may be observed. Myoedema, a mounding of the muscle in response to direct percussion, is painless and electrically silent, and occurs in one third of hypothyroid patients. y Difficulty relaxing the hand grip and exacerbation by cold weather may suggest myotonia. However, unlike myotonia, hypothyroid myopathy involves a slowness of muscle relaxation and contraction, and resolves with correction of the hypothyroid state. y Although sleep apnea is usually of the obstructive type, other possibilities include a central abnormality, chest muscle weakness, and blunted responses to...

Body composition

The correlation between T levels and muscle mass appears stronger than the correlation with muscle strength. In a study of men aged 73-97 years, serum T levels were, independently of age, positively related to isometric grip strength and leg extension strength 92 . In institutionalized men, who have lower T concentrations than healthy elderly men, a correlation between T levels and severity of loss of muscle function could be established 93 . By contrast, two other studies failed to establish correlations between T and strength. In one in elderly men (65-97 years old), a significant correlation was found between FT and muscle mass, but not grip strength 94 . In the other, no correlation between T levels and muscle strength was found 95 . In most RCTs in men over 50, the increase in muscle mass was not associated with statistically significant improvements in muscle strength. Where improved, this effect was mainly seen in the upper limbs with a statistically significant increase in...
