The SonicHand Protocol for Rehabilitation of Hand Motor Function: A Validation and Feasibility Study.

Musical sonification therapy is a new technique that can reinforce conventional rehabilitation treatments by increasing therapy intensity and engagement through challenging and motivating exercises. The aim of this paper is to evaluate the feasibility and validity of the SonicHand protocol, a new training and assessment method for the rehabilitation of hand function. The study was conducted in 15 healthy individuals and 15 stroke patients. The feasibility of implementation of the training protocol was tested in stroke patients only, who practiced a series of exercises concurrently to music sequences produced by specific movements. The assessment protocol evaluated hand motor performance during pronation/supination, wrist horizontal flexion/extension, and hand grasp without sonification. From hand position data, 15 quantitative parameters were computed evaluating mean velocity, movement smoothness, and angular excursions of hand/fingers. We validated this assessment in terms of its ability to discriminate between patients and healthy subjects, test-retest reliability and concurrent validity with the upper limb section of the Fugl-Meyer scale (FM), the functional independence measure (FIM), and the Box and Block Test (BBT). All patients showed a good understanding of the assigned tasks and were able to correctly execute the proposed training protocol, confirming its feasibility. A moderate-to-excellent intraclass correlation coefficient was found in 8/15 computed parameters. The moderate-to-strong correlation was found between the measured parameters and the clinical scales. The SonicHand training protocol is feasible and the assessment protocol showed good to excellent between-group discrimination ability, reliability, and concurrent validity, thus enabling the implementation of new personalized and motivating training programs employing sonification for the rehabilitation of hand function.

[Multidisciplinary protocol for work resumption after occupational osteoarticular injury: case record]. / Protocollo interdisciplinare per il reinserimento lavorativo dopo infortunio osteoarticolare sul lavoro: casistica clinica.

The results obtained with a protocol aimed at work resumption after occupational osteoarticular injury and subsequent rehabilitation are presented: 159 patients (102 males and 57 females: mean age 43.7 years) were evaluated by the physiatrist and the occupational physician, providing indications based on their functional capabilities and task features. After 6 months, 105 out of 130 subjects available for telephonic follow-up (80.7%) had returned to work (8 after changing tasks, 7 part-time). The mean time for work resumption was 9.4 days for those who resumed working completely, 31.4 days for the others. After 12 months, the percentage of working patients (76 out of 93: 81.7%) was superimposable, indicating that the rehabilitation beneficial effect is maximal in the short-medium period. On the whole, the data prove the efficacy of the multidisciplinary rehabilitative approach.

[Return to work after occupational osteoarticular injury: presentation of a multidisciplinary protocol and preliminary data]. / Reinserimento lavorativo dopo infortunio osteoarticolare sul lavoro: presentazione di un protocollo interdisciplinare e dati preliminari.

A protocol for work resumption after occupational osteoarticular injury and subsequent rehabilitation is presented: 97 patients (68 males and 29 females; mean age 42 years) were evaluated by the physiatrist and the occupational physician, providing indications based on their functional capabilities and task features. Up to date, 38 underwent follow-up at 6 months: 30 had returned to work (3 after changing tasks, 4 part-time). The mean time for work resumption was 15 days for the 26 subjects who resumed working completely, 1 month for the 4 who resumed partially. These data are encouraging, and highlight the importance of a multidisciplinary rehabilitative approach to facilitate return to work after occupational injuries.

[Risks of awkward posture]. / Rischi do posture incongrue.

For posture we mean the position of the body in the space and the relationship with its segments. The correct posture is determined by neurophysiological, biomechanical, emotional, psychological and relation factors, enabling us to perform daily and working activities with the lowest energy expenditure. When possible we suggest during posture variation, a preventive measure where there are prolonged fixed activities.

[Results of 2 years of activity]. / Risultati di 2 anni di attività.

Work-related injuries and occupational diseases are a scourge of modern, western societies, which, although technologically advanced, have difficulty in preventing, treating and rehabilitating victims with speed and efficiency. The current hospital neuromotor rehabilitation centres, whether public or accredited private structures, have notable difficulty in meeting the demand, which despite annual fluctuations and variable needs, does not, overall, seem to be decreasing. We present the results of an organization model developed at the "Fondazione Maugeri" Scientific Institute (Pavia, Italy), the criteria used for the activity, the technological innovations employed to determine ability, and the prospects for further development. This model is effective from a health care-rehabilitative point of view, also in the light of the new legislative scenarios, and is sustainable from an economic points of view; overall it is, therefore, efficient.

[Tests of hand functionality in upper limb amputation with prosthesis]. / I test di funzionalità della mano in amputati di arto superiore con protesi.

The need for standardized instruments for clinical measurements has become pressing in the fields of occupational rehabilitation and ergonomics. This is particularly the case for instruments that allow a quantitative evaluation of upper limb function, and especially hand function in patients who have undergone an amputation and then application of an upper limb prosthesis. This study presents a review of the main tests used to evaluate hand function, with a critical analysis of their use in subjects with an upper limb prosthesis. The tests are divided into: tests to evaluate strength, tests to evaluate co-ordination and dexterity, tests of global or overall function, and tests proposed specifically for subjects with an upper limb prosthesis. Of the various tests presented, the authors give their preference to the Bimanual Functional Assessment, Abilhand and/or the ADL Questionnaire, because of the practical usefulness, clinimetric features, simplicity and ease of administration of these tests.

Work-related posttraumatic upper limb disorder. A case report.

In this paper we describe a patient with mor-sensory loss in the right forearm and hand, which persisted more than 2 years after work-related crush trauma of the left hand. Radiographic and electromyographic investigations, somatosensory evoked potentials, CT scans of the encephalus as well as the Minnesota Multiphasic Personality Inventory and the Roarschach test have been performed. On the basis of these investigations, we think this represents a case of conversion disorder with somatic features. Included is a brief overview of other psychological illness with physical findings involving the upper limb.

[An ergonomic study of postures of toll collectors]. / Indagine ergonomica nelle postazioni di "esattori pedaggio".

The working activities of operators in the workstations along the italian motor ways involve repetitive movements of upper limbs and neck with asymmetric postures of the trunk. The tasks examined are characterized by factors potentially dangerous for developing musculo-skeletal disorders, such as repetitivity, and prolonged constrained postures. It is therefore crucial that dimensional and structural characteristics of the workplace are adequately designed, with regard to the anthropometric parameters and the type of activity performed. The results of our "on-site" investigation, using an observational method (OCRA), dedicated computerized modules for postural analysis (software "Vision 3000", Promatek, Ltd.), and recordings of myoelectrical activity (surface EMG) in the muscles of the shoulder girdle, have shown the need of a partial re-designing of the man-workstation system under investigation.

[Evaluation of the capacity of work using upper limbs after radical latero-cervical surgery]. / La valutazione della capacità lavorativa con gli arti superiori dopo intervento di svuotamento latero-cervicale.

Evaluation of arm work capacity after radical neck surgery. The aim of this paper is to describe an approach for the assessment of work capacity in patients who underwent radical neck surgery, including those treated with radiation therapy. Nine male patients, who underwent radical neck surgery 2 months before being referred to our Unit, participated in the study. In addition to manual muscle strength test, we performed the following functional evaluations: 0-100 Constant scale for shoulder function; maximal shoulder strength in adduction/abduction and intrarotation/extrarotation; instrumental. We measured maximal isokinetic strength (10 repetitions) with a computerized dynamometer (Lido WorkSET) set at 100 degrees/sec. During the rehabilitation phase, the patients' mechanical parameters, the perception of effort, pain or discomfort, and the range of movement were monitored while performing daily/occupational task individually chosen on the simulator (Lido WorkSET) under isotonic conditions. On this basis, patients were encouraged to return to levels of daily physical activities compatible with the individual tolerable work load. The second evaluation at 2 month confirmed that the integrated rehabilitation protocol successfully increased patients' capacities and "trust" in their physical capacity. According to the literature, the use of isokinetic and isotonic exercise programs appears to decrease shoulder rehabilitation time. In our experience an excellent compliance has been noted. One of the advantages of the method proposed is to provide quantitative reports of the functional capacity and therefore to facilitate return-to-work of patients who underwent radical neck surgery.

Work capacity of the upper limbs after mastectomy.

Cancer patients are now more often long-term survivors and their needs for returning to social and productive activities have become a primary focus of intervention. The purpose of the present study was to propose an objective evaluation test for predicting endurance capacity in breast cancer patients after surgery, in order to optimize return to work or previous daily activities, and for monitoring changes during rehabilitation. Twenty female patients (mean age: 44 +/- 5), who underwent radical breast surgery 2 months before being referred to our Unit, participated in the study. In addition to the measures of the circumferences in the arm-forearm and manual muscle strength test, we performed the following functional evaluations: 0-100 Constant scale for shoulder function; instrumental evaluation of daily/occupational upper limb activities (Lido WorkSET). We monitored the mechanical parameters, the perception of effort, pain or discomfort, and the range of movement while performing a 3-minute steady daily/occupational task chosen by the subject. Patients were asked to perform the 3-minute test at three different intensities ("moderate", "somewhat hard", "hard") until the perception of fatigue, pain or discomfort was rated > 3 on the 10 point Borg's scale. The 'power-duration' product (Watt x min) defined by the three tests (see Fig. 1) represented the individual tolerable work load, since subjective indicators of pain/discomfort remained within tolerable limits during the exertion. On this basis, patients were encouraged to return to levels of daily physical activities compatible with the individual tolerable work load. The second evaluation, although no statistical analysis was performed, confirmed that the "guided" daily activity in a 2-month period increased patients' capacities and "trust" in their physical capacity.
