Latency to onset and peak of negative deflection and amplitude of the evoked action potential were determined for sensory nerves. Eleven subjects had amplitude and/or latency abnormalities of the sural, superficial peroneal, and median sensory nerves. One additional subject had abnormality of both the sural and superficial peroneal nerves. Five subjects had mononeuropathies and 2 of these also had membrane instability of the abductor hallucis muscle. Ten subjects had clinical or electrophysiologic findings compatible with carpal tunnel syndrome either as an isolated lesion or superimposed on underlying peripheral neuropathy. It was concluded that all subjects with abnormality of 3 sensory nerves (median, sural and superficial peroneal) had findings compatible with diabetic peripheral neuropathy and that additional electrodiagnostic studies (unless otherwise indicated) did not identify additional abnormalities diagnostic of peripheral neuropathy in the remaining subjects.","PeriodicalId":75477,"journal":{"name":"American journal of physical medicine","volume":"63 6","pages":"278-88"},"PeriodicalIF":0.0,"publicationDate":"1984-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17565683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five adult males performed maximal knee extensions and flexions on a modified Orthotron isokinetic dynamometer. Tests were done at four speeds (100-400 degrees/sec) and under two counterbalanced conditions: extension followed by flexion (E/F) and flexion followed by extension (F/E). Simultaneous recordings of torque, knee joint position and agonist/antagonist EMG changes from the quadriceps and hamstring musculature were collected and analyzed. No consistent EMG patterns emerged that inferred intermittent surges of muscular activity as the primary mechanism yielding double peaked torques that characteristically occur in isokinetic exercise. Further analyses revealed relatively small co-contractions of antagonists during the various phases of movement. The findings suggest that gravity and inertia of the limb/lever system were the major factors responsible for limb deceleration and substantive antagonist co-contraction was not required for braking. If isokinetic knee flexion and extension exercises are used for conditioning or developmental purposes of healthy subjects, any distraction of the co-contracting antagonist from the recorded force of the agonist appears to be small once the activity is learned.","PeriodicalId":75477,"journal":{"name":"American journal of physical medicine","volume":"63 6 1","pages":"289-97"},"PeriodicalIF":0.0,"publicationDate":"1984-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1249/00005768-198315020-00268","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66704734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five patients were given the regular hospital diet and low calcium diet (300 mg calcium/day diet) on a randomized cross-over design. The other five patients were given four treatment modalities: a. regular diet, b. low calcium diet, c. low sodium diet (2 gm sodium/day diet), d. low calcium diet plus hydrochlorthiazide 25 mg twice a day according to a cross-over randomized block design. Each treatment regimen lasted two weeks and 24-hour urinary calcium concentrations were determined weekly. The result indicated that low calcium diet, low sodium diet or low calcium diet plus hydrochlorthiazide reduced hypercalciuria significantly (P less than 0.01). Low calcium diet combined with hydrochlorthiazide was the most effective treatment for hypercalciuria. In retrospective studies, we found that recently injured patients developed hypercalciuria, however, there was no significant difference in the incidence of bladder stone formation in patients with hypercalciuria compared with those with normal urinary calcium excretion.","PeriodicalId":75477,"journal":{"name":"American journal of physical medicine","volume":"63 4","pages":"182-7"},"PeriodicalIF":0.0,"publicationDate":"1984-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17440487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In healthy people, the onset of isometric contraction is initiated by smaller motor units with briefer durations and higher spike frequencies. With the progression of contraction and muscular fatigue, electromyographic decrease in frequency and an increased spike duration occur. In our study, these findings were presented in subjects at the Final Value (FV) of electromyography before and after LE. In 8 subjects, the Initial Value (IV) of spike duration was longer after LE and a decrease in the frequency of electromyography was found in 9 of the 12 subjects. The changes in these two parameters at the onset of the BB contraction after LE may be due to the existence of an electrophysiological transfer effect. Eight subjects sustained the isometric BB contraction longer after LE than before LE. This may be explained by a diverting activity or other factors. Venous lactic acid was measured in 7 subjects and showed an increase after LE. No definite correlation between electromyographic changes and lactic acid was found.","PeriodicalId":75477,"journal":{"name":"American journal of physical medicine","volume":"63 3","pages":"113-21"},"PeriodicalIF":0.0,"publicationDate":"1984-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17784849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Relationship between myoelectric signals and blood lactate during incremental forearm exercise.","authors":"T Moritani, H Tanaka, T Yoshida, C Ishii, T Yoshida, M Shindo","doi":"","DOIUrl":"","url":null,"abstract":"Five men performed incremental forearm exercise by using a modified hand grip dynamometer while external loads (1 Kg metal plate) were added at each succeeding minute until volitional exhaustion occurred. Myo-electric signals were recorded from the belly of the flexor carpi radialis-palmaris longus. By the use of an LSI-11/23 minicomputer, the digitized data were processed for integrated EMG (IEMG) and mean power frequency (MPF) by means of 512 point fast Fourier transform. Data from individuals revealed that venous lactate correlated highly with IEMG (range: 0.977 to 0.857, P less than 0.001) and MPF (-0.960 to -0.862, P less than 0.001) during the incremental exercise. Group data revealed that none of the parameters tested showed any significant changes between the onset of lactate threshold (LT), i.e., the onset of abrupt increases in lactate, and one minute prior to LT. However, when these parameters were tested between LT and one minute after LT, significant differences were observed for venous lactate (t = 3.16, P less than 0.05), IEMG (t = 3.02, P less than 0.05) and MPF (t = 3.84, P less than 0.05). It was concluded that analysis of myo-electric signals may provide a non-invasive measure of lactate threshold after which dynamic equilibrium of lactate production and utilization becomes unbalanced during the incremental forearm exercise.","PeriodicalId":75477,"journal":{"name":"American journal of physical medicine","volume":"63 3","pages":"122-32"},"PeriodicalIF":0.0,"publicationDate":"1984-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17784850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
