By blocking the release of neurotransmitters, botulinum toxin A (BoNT-A) is an effective treatment for muscle over-activity and pain in stroke patients. BoNT-A has also been reported to increase passive range of motion (p-ROM), the decrease of which is mainly due to muscle shortening (i.e., muscle contracture). Although the mechanism of action of BoNT-A on p-ROM is far from understood, pain relief may be hypothesized to play a role. To test this hypothesis, a retrospective investigation of p-ROM and pain was conducted in post-stroke patients treated with BoNT-A for upper limb hypertonia. Among 70 stroke patients enrolled in the study, muscle tone (Modified Ashworth Scale), pathological postures, p-ROM, and pain during p-ROM assessment (Numeric Rating Scale, NRS) were investigated in elbow flexors (48 patients) and in finger flexors (64 patients), just before and 3-6 weeks after BoNT-A treatment. Before BoNT-A treatment, pathological postures of elbow flexion were found in all patients but one. A decreased elbow p-ROM was found in 18 patients (38%). Patients with decreased p-ROM had higher pain-NRS scores (5.08 ± 1.96, with a pain score ≥8 in 11% of cases) than patients with normal p-ROM (0.57 ± 1.36) ( p < 0.001). Similarly, pathological postures of finger flexion were found in all patients but two. A decreased finger p-ROM was found in 14 patients (22%). Pain was more intense in the 14 patients with decreased p-ROM (8.43 ± 1.74, with a pain score ≥ 8 in 86% of cases) than in the 50 patients with normal p-ROM (0.98 ± 1.89) ( p < 0.001). After BoNT-A treatment, muscle tone, pathological postures, and pain decreased in both elbow and finger flexors. In contrast, p-ROM increased only in finger flexors. The study discusses that pain plays a pivotal role in the increase in p-ROM observed after BoNT-A treatment.

Objective: To develop and validate a quick observational clinical tool, the Functional ASsessment Test for Upper Limb (FAST-UL), for the evaluation of upper limb impairment in goal-directed functional-oriented motor tasks after stroke., Design: Observational, cross-sectional, psychometric study., Setting: Inpatient and outpatient rehabilitation clinic., Participants: A total of 188 post-stroke survivors (mean age 65.2±17.7 years, 61% men, 48% with ischemic stroke and 66% in the sub-acute phase; N=188)., Interventions: Not applicable., Main Outcome Measures: Principal component analysis and Rasch analysis through a Partial Credit Model were used to assess the structure and psychometric properties of the 5 items of the FAST-UL (Hand to Mouth [HtM], Reach to Target, Prono-Supination, Grasp and Release, and Pinch and Release [PaR])., Results: The Cronbach's α equal to 0.96 was indicative of an acceptable internal consistency; the reliability, as measured through the Person Separation Reliability equal to 0.87, was good. The FAST-UL tool was unidimensional. All the FAST-UL items were found to fit well the Rasch measurement model. The easiest to perform FAST-UL item was the HtM movement while the most difficult was the PaR movement., Conclusions: The FAST-UL is a quick, easy-to-administer observational assessment tool of upper limb motor impairment in post-stroke survivors with good item-level psychometric properties., (Copyright © 2022 American Congress of Rehabilitation Medicine.

Background: The cardiorespiratory comorbidity can reduce the participation in the rehabilitation project of patients with motor disorders., Aim: The first aim of the study was to assess the frequency of cardiopulmonary comorbidity in inpatient rehabilitation units in Italy. The second aim was to evaluate the influence of cardiorespiratory comorbidity on some process and outcome indicators., Design: Data collection with a questionnaire sent to Physical and Rehabilitation Medicine specialists., Setting: Inpatient Rehabilitation Units., Population: Patients admitted to Rehabilitation Units with neurological and orthopedic disability., Methods: A questionnaire was sent to 33 Rehabilitation Units in Italy., Outcome: Length of stay in hospital (LOS), percentage of transfer to acute wards, level of satisfaction of the Physicians related to the degree of functional recovery of patients with cardiopulmonary comorbidity. In a subgroup of patients with and without cardiopulmonary comorbidity indicators were also used to retrospectively assess functional recovery during the hospitalization., Results: Analysis were made on 16 complete responses received. Data of 909 subjects were evaluated. The mean incidence of cardiovascular and respiratory diseases is high: 61.50%. The length of hospitalization (LOS) in patients with cardiac and respiratory comorbidity is significantly longer than in subjects without associated disease (46.55, SD 21.00 days vs. 37.26, SD 18.97; P<0.05). The number of transfers to acute wards is significantly higher in subjects with cardiorespiratory comorbidity (8.62% vs. 2.44%; P<0.05). Eleven out of 16 medical doctors (69%) said they were "quite satisfied" for the degree of functional recovery of patients with comorbidity. A group of patients with neurological disabilities associated with cardiorespiratory disease had significantly lower Functional Independence Measure (FIM) score at admission (55.36, SD 20.62, vs. 73.72, SD 22.15; P<0.05) than these without comorbidity. At discharge the subjects of the two groups assessed, independently from the presence of cardiorespiratory comorbidity, present no statistically significant difference of FIM scale values., Conclusion: The high frequency of cardiorespiratory comorbidity in patients with motor disorders negatively influenced the LOS and percentage of transfer to acute wards but not necessarily the functional results. It is, therefore, necessary to train the medical doctor who specializes in physical and rehabilitation medicine also in the clinical management of complex patients., Clinical Rehabilitation Impact: The results of the survey suggest that rehabilitation is useful even in patients with motor disorders and cardiorespiratory comordibity.
