Background Paresis acquired in the intensive care unit (ICU) is common in patients who are critically ill and independently predicts mortality and morbidity. Manual muscle testing (MMT) and handgrip dynamometry assessments have been used to evaluate muscle weakness in patients in a medical ICU, but similar data for patients in a surgical ICU (SICU) are limited. Objective The purpose of this study was to evaluate the predictive value of strength measured by MMT and handgrip dynamometry at ICU admission for in-hospital mortality, SICU length of stay (LOS), hospital LOS, and duration of mechanical ventilation. Design This investigation was a prospective, observational study. Methods One hundred ten patients were screened for eligibility for testing in the SICU of a large, academic medical center. The Acute Physiology and Chronic Health Evaluation (APACHE) II score, diagnoses, and laboratory data were collected. Measurements were obtained by MMT quantified with the sum (total) score on the Medical Research Council Scale and by handgrip dynamometry. Outcome data, including in-hospital mortality, SICU LOS, hospital LOS, and duration of mechanical ventilation, were collected for all participants. Results One hundred seven participants were eligible for testing; 89% were tested successfully at a median of 3 days (25th–75th percentiles=3–6 days) after admission. Sedation was the most frequent barrier to testing (70.6%). Manual muscle testing was identified as an independent predictor of mortality, SICU LOS, hospital LOS, and duration of mechanical ventilation. Grip strength was not independently associated with these outcomes. Limitations This study did not address whether muscle weakness translates to functional outcome impairment. Conclusions In contrast to handgrip strength, MMT reliably predicted in-hospital mortality, duration of mechanical ventilation, SICU LOS, and hospital LOS.

Objectives: To reach agreement on standardized protocols for assessing upper limb strength and grip and pinch force for upper limb reconstructive surgery for tetraplegia. Methods: Selected members of an expert panel composed of international therapists formed at the 2018 International Congress for Upper Limb Surgery for Tetraplegia conducted a literature review of current practice that identified gaps and inconsistencies in measurement protocols and presented to workshop attendees. To resolve discrepancies, a set of questions was presented to workshop attendees who voted electronically. Consensus was set at 75% agreement. Results: For manual muscle testing, consensus was reached for using the Medical Research Council scale, without plus or minus, and the use of resistance through range when testing grade 4 and grade 5 strength. Pectoralis major and serratus anterior should be routinely tested, however there was no consensus on other shoulder muscles. Grip and pinch strength should be tested according to the American Society of Hand Therapists positioning. For grip strength, either the Jamar or Biometrics dynamometer expressed in kilograms should be used. For grip and pinch strength, three measurements should be performed at each testing. No consensus was reached on a device for pinch strength. Conclusion: This work is an important step to enable comparable data in the future. Further consensus methods will work toward developing more comprehensive guidelines in this population. Building international consensus for pre- and postoperative measures of function supports objective evaluation of novel therapies and interpretation of multicenter studies.

Objective To investigate the clinical demographics and rehabilitative assessments of encephalitis survivors admitted to a rehabilitation center, and to confirm the effects of inpatient rehabilitation manifested by changes in muscle strength and function after hospitalization.Methods Data of encephalitis survivors who received rehabilitation at our institution from August 2009 to August 2019 were reviewed. Medical charts were retrospectively reviewed, and motor, functional, and cognitive assessments were collected. Manual muscle testing (MMT), Fugl-Meyer Assessment (FMA), Berg Balance Scale (BBS), Functional Ambulation Category (FAC), Korean version of Modified Barthel Index (K-MBI), grip strength, Box and Block Test (BBT), and Korean version of Mini-Mental State Examination (K-MMSE) were performed, and the results upon admission and discharge were compared and analyzed.Results Most of the patients with encephalitis admitted to our institution had viral or autoimmune etiologies. The assessment results of 18 encephalitis patients upon admission and discharge were compared. The total K-MBI score, FAC, grip strength, and BBT significantly improved, but not the MMT and FMA. Subgroup analysis was performed for viral and autoimmune encephalitis, which are the main causes of the disease, but there was no difference in items with significant changes before and after hospitalization.Conclusion Encephalitis survivors showed a significant improvement in functional assessment scale during their hospital stay through rehabilitation, without significant changes in motor strength. Hence, we can conclude that encephalitis survivors benefit from inpatient rehabilitation, targeting functional gains in activities of daily living training more than motor strength.

Abstract Lesions of the peripheral nervous system (PNS), whether due to injury or illness, commonly result in residual symptoms and signs and, hence, permanent impairment. The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fourth Edition, divides PNS deficits into sensory and motor and includes pain in the former. This article, which regards rating sensory and motor deficits of the lower extremities, is continued from the March/April 2000 issue of The Guides Newsletter. Procedures for rating extremity neural deficits are described in Chapter 3, The Musculoskeletal System, section 3.1k for the upper extremity and sections 3.2k and 3.2l for the lower limb. Sensory deficits and dysesthesia are both disorders of sensation, but the former can be interpreted to mean diminished or absent sensation (hypesthesia or anesthesia) Dysesthesia implies abnormal sensation in the absence of a stimulus or unpleasant sensation elicited by normal touch. Sections 3.2k and 3.2d indicate that almost all partial motor loss in the lower extremity can be rated using Table 39. In addition, Section 4.4b and Table 21 indicate the multistep method used for spinal and some additional nerves and be used alternatively to rate lower extremity weakness in general. Partial motor loss in the lower extremity is rated by manual muscle testing, which is described in the AMA Guides in Section 3.2d.

Capos Syndrome

Abstract Background CAPOS syndrome (cerebellar ataxia, areflexia, pescavus, optic atrophy, and sensorineural hearing loss) is a rare congenital autosomal dominant disorder. The resulting neurological sequelae of impairments are progressive in nature and may interfere with functional independence, performing activities of daily living (ADL’s), and subsequently, affecting the quality of life (QOL). Since it is an extremely rare disorder, there is a severe dearth in the literature about how specific physiotherapy interventions may affect their functional status. Therefore, our objective was to investigate the effects of proprioceptive neuromuscular facilitation (PNF) and Frenkel’s coordination exercises on functional recovery in a patient with CAPOS syndrome. Case presentation We herein present a case of a 25-year-old Indian male with complaints of generalized body weakness, difficulty visualizing distant objects, nystagmus, progressive sensorineural deafness, and ataxia. He was rehabilitated with a structured/customized physiotherapy protocol consisting of PNF approach and coordination exercises for 4 weeks, 6 days/week, 60 min daily. An improvement in overall functional performance of patient as per post-intervention scores of manual muscle testing, trunk control measurement scale, functional independence measure (components of self-care, transfers, and locomotion), and decline in severity of ataxia on scale for assessment and rating of ataxia scale was observed. Conclusion PNF and Frenkel’s exercises resulted in an improvement in overall functional performance of the patient. Improvement was observed in post-test scores of Manual Muscle Testing (MMT), Trunk Control Measurement Scale (TCMS), and Functional Independence Measure (FIM) for the components of self-care, transfers, and locomotion. Additionally, results also showed a decline in severity of ataxia on post-test scores of scale for the assessment and rating of ataxia (SARA) scale (i.e., from severe to moderate).

Objective To examine the pain-reducing effects of intra-articular oxygen–ozone (O2O3) injections and mechanical focal vibration (mFV) versus O2O3 injections alone in patients with knee osteoarthritis. Methods Patients with chronic pain (>6 weeks) due to knee osteoarthritis (II–III on the Kellgren–Lawrence scale) were consecutively enrolled and divided into two groups: O2O3 (n = 25) and O2O3-mFV (n = 24). The visual analog scale (VAS), Knee Injury and Osteoarthritis Outcome Score (KOOS), and Medical Research Council (MRC) Manual Muscle Testing scale were administered at baseline (before treatment), after 3 weeks of treatment, and 1 month after the end of treatment. Patients received three once-weekly intra-articular injections of O2O3 into the knee (20 mL O3, 20 μg/mL). The O2O3-mFV group also underwent nine sessions of mFV (three sessions per week). Results The VAS score, KOOS, and MRC score were significantly better in the O2O3-mFV than O2O3 group. The within-group analysis showed that all scores improved over time compared with baseline and were maintained even 1 month after treatment. No adverse events occurred. Conclusion An integrated rehabilitation protocol involving O2O3 injections and mFV for 3 weeks reduces pain, increases autonomy in daily life activities, and strengthens the quadriceps femoris.

Background. Different types of mattresses affect sleep quality and waking muscle power. Whether manual muscle testing (MMT) predicts the cardiovascular effects of the bedding system was explored using ten healthy young men.Methods. For each participant, two bedding systems, one inducing the strongest limb muscle force (strong bedding system) and the other inducing the weakest limb force (weak bedding system), were identified using MMT. Each bedding system, in total five mattresses and eight pillows of different firmness, was used for two continuous weeks at the participant’s home in a random and double-blind sequence. A sleep log, a questionnaire, and a polysomnography were used to differentiate the two bedding systems.Results and Conclusion. Heart rate variability and arterial pressure variability analyses showed that the strong bedding system resulted in decreased cardiovascular sympathetic modulation, increased cardiac vagal activity, and increased baroreceptor reflex sensitivity during sleep as compared to the weak bedding system. Different bedding systems have distinct cardiovascular effects during sleep that can be predicted by MMT.
