Gamified Physical Rehabilitation for Older Adults With Musculoskeletal Issues: Pilot Noninferiority Randomized Clinical Trial

BACKGROUND

Resource-rich countries are facing the challenge of aging societies, a high risk of dependence, and a high cost of care. Researchers attempted to address these issues by using cost-efficient, innovative technology to promote healthy aging and regain functionality. After an injury, efficient rehabilitation is crucial to promote returning home and prevent institutionalization. However, there is often a lack of motivation to carry out physical therapies. Consequently, there is a growing interest in testing new approaches like gamified physical rehabilitation to achieve functional targets and prevent rehospitalization.

OBJECTIVE

The purpose of this study is to assess the effectiveness of a personal mobility device compared with standard care in the rehabilitation treatment of patients with musculoskeletal issues.

METHODS

A total of 57 patients aged 67-95 years were randomly assigned to the intervention group (n=35) using the gamified rehabilitation equipment 3 times a week or to the control group (n=22) receiving usual standard care. Due to dropout, only 41 patients were included in the postintervention analysis. Outcome measures included the short physical performance battery (SPPB), isometric hand grip strength (IHGS), functional independence measure (FIM), and the number of steps.

RESULTS

A noninferiority related to the primary outcome (SPPB) was identified during the hospital stay, and no significant differences were found between the control and intervention groups for any of the secondary outcomes (IHGS, FIM, or steps), which demonstrates the potential of the serious game-based intervention to be as effective as the standard physical rehabilitation at the hospital. The analysis by mixed-effects regression on SPPB showed a group×time interaction (SPPB_I_t1=-0.77, 95% CI -2.03 to 0.50, P=.23; SPPB_I_t2=0.21, 95% CI -1.07 to 0.48, P=.75). Although not significant, a positive IHGS improvement of more than 2 kg (Right: 2.52 kg, 95% CI -0.72 to 5.37, P=.13; Left: 2.43 kg, 95% CI -0.18 to 4.23, P=.07) for the patient from the intervention group was observed.

CONCLUSIONS

Serious game-based rehabilitation could potentially be an effective alternative for older patients to regain their functional capacities.

Muscle size, strength, and physical function in response to augmented calorie delivery: A TARGET sub-study

PURPOSE

Augmented calories may attenuate muscle loss experienced in critical illness. This exploratory sub-study assessed the effect of augmented calorie delivery on muscle mass, strength, and function.

MATERIALS AND METHODS

Patients in The Augmented versus Routine approach to Giving Energy Trial (TARGET) randomised to 1.5 kcal/ml or 1.0 kcal/ml enteral formulae at a single-centre were included. Ultrasound-derived muscle layer thickness (MLT) at quadriceps, forearm and mid-upper arm, and handgrip strength, were measured weekly from baseline to hospital discharge, and 3- and 6-months. Physical function was assessed at 3- and 6-months using the 'get up and go' and 6-min walk tests. Data are mean ± SD.

RESULTS

Eighty patients were recruited (1.5 kcal: n = 38, 58 ± 14y, 60%M, APACHE II 20 ± 7; 1.0 kcal: n = 42, 54 ± 18y, 66%M, APACHE II 22 ± 10). The 1.5 kcal/ml group received more calories with no difference in quadriceps MLT at any timepoint including ICU discharge (primary outcome) (2.90 ± 1.27 vs 2.39 ± 1.06 cm; P = 0.141). Relationships were similar for all MLT measures, handgrip strength, and 6-min walk test. Patients in the 1.5 kcal/ml group had improved 'get up and go' test at 3-months (6.66 ± 1.33 vs. 9.11 ± 2.94 s; P = 0.014).

CONCLUSION

Augmented calorie delivery may not attenuate muscle loss or recovery of strength or function 6-months post-ICU, but this requires exploration in a larger trial.

Early anthropometry, strength, and function in survivors of critical illness

BACKGROUND

Critically ill patients experience acute muscle wasting and long-term functional impairments, yet this has been inadequately categorised early in recovery.

OBJECTIVE

This observational study aimed to evaluate anthropometry, strength, and muscle function after intensive care unit discharge.

METHODS

Adult patients able to complete study measures after prolonged intensive care unit stay (≥5 d) were eligible. Demographic and clinical data were collected, and bodyweight, height, triceps skinfold, trunk length, handgrip strength, 6-minute walk test, whole-body dual-energy x-ray absorptiometry, and mid-thigh, knee, and above-ankle circumferences were measured. Body cell mass was calculated from these data. Data are presented as mean (standard deviation) or median [interquartile range].

RESULTS

Fourteen patients (50% male; 57 [10.5] years) were assessed 11.1 (6.9) d after intensive care unit discharge. Patients lost 4.76 (6.66) kg in the intensive care unit. Triceps skinfold thickness (17.00 [8.65] mm) and handgrip strength (12.60 [8.57] kg) were lower than normative data. No patient could commence the 6-minute walk test. Dual-energy x-ray absorptiometry-derived muscle mass correlated with handgrip strength (R = 0.57; 95% confidence interval = 0.06-0.85; p = 0.03), but body cell mass did not.

CONCLUSIONS

Anthropometry and strength in intensive care unit survivors are below normal. Muscle mass derived from dual-energy x-ray absorptiometry correlates with handgrip strength but body cell mass does not.

Mobility and clinical outcome of patients admitted to an intensive care unit

Abstract Introduction: The hospital environment exacerbates the effects of immobility due to several exposure factors, and the functional assessment of individuals using reliable instruments is vital. Objective: To determine the relationship between functional mobility and the clinical outcome of patients admitted to an intensive care unit. Method: This is a prospective quantitative longitudinal study, approved by the institutional research ethics committee, carried out in the intensive care unit of a University Hospital. Clinical data and the Acute Physiology and Chronic Health Evaluation (APACHE II) score were collected 24 hours after admission. The Perne Score was used to analyze patient mobility. Results: 33 patients participated, 63% female. With respect to mobility and transfers, 69.7% required total assistance from the supine to the sitting position and 70% to maintain balance, 9.1% needed minimum assistance from sitting to standing, and 100% total assistance for walking and endurance exercises. The main barriers to mobility were invasive ventilation (60%), assistive devices and intravenous infusion (100%). The following Perne Score domains were significantly associated with the outcome: mental status (p = 0.040), barriers to mobility (p = 0.016), strength (p = 0.010), mobility in bed (p = 0.024) and the total Perme Score ( p = 0.002). There were also significant associations between invasive ventilation and low Perme Scores (p = 0.000), and the Richmond Agitation-Sedation Scale (RASS) (-5 and -4) and death in 66.7% of patients (p = 0.011). The Perme Score and RASS (R = 0.745) were moderately correlated and APACHE II and Perme Score inversely moderately correlated (R = -0.526). Conclusion: Mobility assessed by the Perme Score was related to the clinical outcome and strongly associated with sedation level and patient severity.
